1. Introduction
Promoting economic prosperity, social justice, and ecological sustainability requires the rapid decarbonization of our global energy system in favor of renewable sources of energy. Our planetary transition to a just and sustainable energy future unfolds at widely different rates across different government contexts, within and across nations [
1] In the United States (US), the Biden Administration set a target to achieve 100% ‘clean’ power by 2035 with the broad goal of attaining net zero emissions by 2050 [
2]. The anticipated transition scenario predicts that wind and solar sources will account for the highest share of all future electricity sources, representing between 60 and 80 percent [
2]. Recent news analysis, however, estimates that 15% of counties across the US have banned wind turbines, solar fields, and/or other green energy developments [
3] and the majority of wind developers (80%) and solar developers (67%) identify local land use regulations as the main barrier to green energy installation [
4]. Yet, current scholarship assesses the degree to which local governments enable or block green energy installation; the factors associated with differential action are underdeveloped.
This phenomenon of local land use planning powers being used to inhibit, undermine, or otherwise complicate federal or state policy aims raises complicated questions for energy scholars and practitioners alike, questions that have not been robustly investigated to date. Local governments in most states have tremendous leverage to advance or hold back wind and solar projects, irrespective of the goals of federal and state governments. Utility-scale wind and solar siting regulations, which involve a local authority dictating the procedures, standards, and conditions that inform how, when, and where wind and solar capacity is installed, are very commonly under the jurisdiction of county governments [
5,
6]. Given the location of major belts of wind and solar potential in the Great Plains and Sun Belt [
3], proposed projects are in areas that tend to be more politically conservative, less comfortable with government regulation of all kinds, and highly protective of private property rights. Together, these contextual factors create a fast-moving, complicated, and oftentimes vexing regulatory environment for green energy advocates and developers seeking to invest in wind and solar facilities [
7]. They also raise questions of whether counties in greater need of economic development opportunities to help stem decline may be left behind in renewable energy installation.
Nevertheless, few research studies have investigated how local factors influence these regulations. An initial analysis by Lerner [
8] on these factors modeled the relationship between developers and the counties and how it affects the regulations. However, they only modelled a sample of counties from states, not a census of counties within a state. Another study by [
9] modelled the economic tradeoffs of adopting these regulations and their role in policy diffusion but did not focus on land use regulations. In both papers, a gap remains as to the local factors that lead to regulations adopted or not adopted and the type of regulation adopted, using a comprehensive current and statewide database.
Our research, which focuses specifically on wind regulations, responds to these challenges. We pose two overarching research questions: (1) How do local regulations of wind facilities vary at the county level? And (2) what factors explain the variation in local wind regulations? Together, the answers to these two questions will provide vital insights for policymakers at the federal, state, and local levels and provide a foundation for future scholarship on what promises to be a multi-decadal process of global consequence: planning for a just energy future. We also expand the scope of policy types by introducing a classification of regulations. These include zoning, wind energy ordinance, development agreements, county moratorium, and state moratorium. Prior studies do not make a distinction in the regulations and model them as zoning regulations, yet counties can use a different set of policy types to regulate these developments. Moreover, we investigate how social, technical, and planning considerations relate to the regulations observed.
To answer these questions, our research began with creating a geospatial information system (GIS) database of the local energy regulations available for all 105 counties in Kansas, a top state for wind potential, and a recent hotbed of local actions that both facilitate and block renewable energy investments. We used this census of Kansas regulations to answer our descriptive question about the variation in the policy landscape. Then, we coupled the database with secondary data, including internal county factors and broader external factors that may explain the observed patterns of variation.
Next, we review the literature to understand local siting of renewable energy facilities, including the federal and state policy framework, local land use planning, and issues specific to renewable energy. The literature review leads to our conceptual framework, which in turn guides our analysis of factors driving variation in local wind regulations, using multivariate regression modelling. After describing our research design and methods, we present our findings, which make it clear that planners and policymakers do, in fact, have levers that can advance or encumber wind transitions. We conclude by highlighting the policy implications of our findings, as well as laying out ideas for future research.
2. Materials and Methods
2.1. The Critical Role of Local Regulation in the Renewables Energy Transition
The United States has set ambitious targets for energy transition across different sectors of the economy. This transition, often referred to as the “green energy” or “clean energy” transition, aims to reduce the consumption of fossil fuels and embrace renewable energy alternatives [
10,
11,
12,
13,
14]. Rising energy demands, carbon dioxide emissions, and increasingly negative impacts of climate change necessitate this transition [
6,
11,
15,
16,
17] with utility-scale renewable energy projects playing an even more important role in achieving climate goals [
18]. Wind energy is a key renewable source, with the Great Plains region of the US poised to contribute significantly [
3,
6]. To meet the transition goals, it is estimated that the United States needs wind power to grow by 70–145 Gigawatts per year by the end of the decade, which is four times the current annual development trends [
13] (the transition to 100% green energy promises to yield net benefits far exceeding the associated costs, with benefit-to-cost ratios ranging from 2.2 to 4.8 and total net benefits estimated between USD 900 billion and USD 1.3 trillion by 2035 [
12]. A renewable energy grid could reduce environmental and health costs by USD 1.7 trillion and prevent approximately 93,000 premature deaths by 2050 [
19].
Concerns about increased wind energy capacity abound. Specific concerns include visual impacts, as large wind turbines can be seen far from the generation site and may be perceived as ugly or disruptive to the landscape, and noise pollution, as the sounds of rotating blades may carry over distances. Environmental concerns include the fragmentation of habitats, although this concern may be mitigated in instances where habitats have already been fragmented, which is typically the case in heavily agricultural areas like Kansas. Wildlife mortality can be a concern as well, although here, too, the scope of impact is dwarfed by other pervasive problems, such as bird kills by domestic cats and the loss of critical habitat due to climate change. With the increased deployment of wind installations and industry responses to the impacts (such as recent developments in radar linkages that reduce light pollution by having aircraft warning lights only activate when a plane is near), the negative impacts of wind installations are evolving.
Fossil fuel-based energy systems in the US lose about 67% of energy from production to use, with up to 80% inefficiency in the transportation sector [
20,
21]. In contrast, renewables convert energy directly at the source, achieving efficiencies of up to 90%, as seen with electric vehicles using renewable energy [
22]. The economic impacts of wind energy developments are significant, especially in rural areas where most of the projects are situated [
23]. Local communities benefit economically through lease payments to landowners and increased tax revenues [
18,
24]. The ambitious green energy targets are projected to generate about 500,000 to 1 million jobs per year in the green energy sector alone [
25]. The ‘just energy’ movements may result in a more equitable distribution of costs and benefits in the aim of shifting energy sources.
A major constraint to achieving urgent global emissions reduction and generating foreseeable economic and societal benefits from renewable energy is the devolution of land use authority to the local level in the United States, which empowers local governments to enable or block the transition [
26,
27]. Zoning and land use control typically lie at the county and municipal level, subjecting transition activities to local regulations that can outright ban renewable energy projects or functionally do so with strict limitations. Scholars have begun to call attention to local ordinances arising from local opposition as a primary cause of delays and cancellation, along with the challenge of connecting a project to the electric grid [
4] (grid integration is an additional challenge but one that industry experts are optimistic that the sector can solve it [
28]. In 2023, about 80% of wind energy developers cited local ordinances or zoning as the leading cause of their project cancellation [
29]. Approximately 60% cited these regulations as the critical causes of project delays, second only to grid interconnection challenges. Projects were most delayed during the site control and local permission phases, with 62% of respondents anticipating that local siting authorities will increase with community opposition [
4]. In recent years, the energy transition has slowed down, with a decline in wind energy generation in 2024 for the first time since the 1990s. According to the US Energy Information Administration, wind generation in 2023 was about 425 Terawatt-hours (TWh) compared to 434 TWh in 2022, representing a decrease of 2.1% [
11]. This decline was largely observed in the Midwest, including states like Kansas, which generated 47% of its total energy from wind in 2022 compared to 46.2% in 2023 [
30].
Yet, few studies offer empirical insights on the local regulatory network underpinning the renewable energy transition, and little attention has been paid to the dynamic and rapidly evolving array of approaches used by local jurisdictions [
19]. At the local level, renewable energy transition initiatives will remain a hotly contested arena of political action, especially given that local ordinance development and implementation are much more accessible to non-experts than state and federal policy. Understanding patterns in wind energy development regulations and factors driving variation in local regulations will help practitioners and scholars design and study policy adjustments to better achieve climate goals.
2.1.1. Local Options for Regulating the Renewable Energy Transition
Local land use regulations, especially zoning ordinances, legally dictate suitable activities for specific land areas (as well as issues like density, design, and infrastructure) and thus have a tremendous influence on renewable energy installations [
31,
32,
33]. In theory, these local land use regulations are guided by local comprehensive plans, which offer general guidelines and policy directions for the community, developed through extensive public engagement over a period of one or more years [
34,
35,
36]. However, in most states with areas of high wind potential, local plans often lack the force of law, if they exist at all. This context reinforces the crucial power of local land use regulations, which can be enacted or modified by local county or municipal commissions, in some cases, in a single meeting based on the perspectives of a small number of commissioners.
In contrast to renewable energy production, fossil fuels have historically faced few local regulatory hurdles. Traditional land use categories, like public utility and industrial use, have been used to classify power production activities, such as coal plants, oil refineries, pipelines, and transmission lines [
34,
35]. Given the large size of such facilities and the history of strong federal and state interests to supersede local authority through tools like eminent domain (whether in the name of economic development or national security), local plans and local land use regulation have not played a major role in fossil fuel development, compared to the role they already play for renewable sources.
Local regulations, as much as they are critical to wind development, exist in a complex regulatory system. Obtaining construction approval for a large-scale wind installation involves a multi-step, intricate process with multiple permits commonly needed for a single project, often from Federal, Tribal, or State authorities [
7,
37]. Wind energy developers typically navigate consent and/or ground lease agreements from the private landowners before any siting permits or construction can proceed, with other easements and covenants sometimes in play [
38]. These agreements or contracts, notably known as Wind Energy Land Agreements (WELA), spell out the terms of use of the property, duration, and payments that will be made to the owner by the developer.
Recently, renewable energy installations such as solar and wind farms have been added and incorporated into existing land uses, often on open land or integrated with agricultural activities [
2,
39]. These renewable energy uses can be categorized into resource production, transmission, and storage land uses [
40,
41]. Additional approaches, though uncommon, are proposed for adoption in land use planning to enable cost-effective grid-connected renewable energy development [
42]. These zones possess attributes facilitating cost-effective renewable energy development, such as abundant resources, suitable topography, proximity to infrastructure, high energy demand, and strong developer interest. Another method used for electricity production is power sector planning, which involves market, geographical, policy, and labor factors [
43]. Again, despite their critical role, county regulations related to wind generation installation remain an understudied aspect of this regulatory framework.
2.1.2. Land Use Approaches to Wind Development
At the broadest level, we conceive local land use approaches to wind development as enabling or blocking. The former aims at attracting or at least allowing wind installations, and the latter aims at prohibiting or limiting wind installations. Enabling and blocking regulations in states with rich wind potential can take one of four primary forms.
First, counties can modify their existing zoning ordinances to include provisions related to wind installations, just as zoning can address a wide array of other land uses like housing, industry, commerce, and education. Not all counties have existing zoning ordinances, particularly in less populous rural counties. Second, counties can adopt a wind-specific zoning regulation, which essentially serves as an addendum to existing zoning (if general zoning exists) or as a use-specific zoning code (where general zoning does not exist). Third, counties can enable wind installations through development agreements. These one-off agreements between a county and a wind developer provide the regulations for a single, specific, proposed project, functioning as a one-time, wind-specific zoning code. Sometimes, these development agreements include payments in lieu of taxes (PILOTs) that include fees and community development grants, which are appealing to county authorities who may be expecting wind developers to fund county development [
18,
44]. (PILOT payments are considered voluntary for renewable energy farms due to property tax exemptions by the state [
45]. Some counties also transfer road repair costs to wind farm developers [
46]. This makes jurisdictions with wind resources more inclined to accept wind energy proposals, especially if they need more financial resources. For example, in Kansas, farmers facing hardships have found lease payments from wind farms helpful [
47]. Fourth, the primary tool available to counties to block development is a moratorium, which can prohibit the development of wind installation in perpetuity (i.e., a ban) or prohibit development until wind regulations are enacted as part of the zoning ordinance or as a stand-alone ordinance (i.e., a temporary moratorium) [
48,
49]. Some counties, however, may choose a more complicated path of intentionally (or unintentionally) blocking wind installations by using the specific provisions of the zoning code or wind-specific regulation to greatly limit or even eliminate acceptable sites for wind installations.
The distinction between “blocking” and “enabling” regulations in the context of wind siting is critical for understanding how regulatory frameworks can either hinder or facilitate the development of renewable energy projects. “Blocking” regulations impose stringent restrictions that can prevent the establishment of wind farms, while “enabling” regulations create a supportive environment that encourages development through incentives and streamlined processes. Blocking regulations often arise from environmental concerns, land use conflicts, and community opposition. In the United States, the siting of wind farms is heavily influenced by ecological considerations [
50], recognizing the need for an ecological risk-based management approach to mitigate potential impacts on wildlife. This type of regulatory framework can cause delays or the outright denial of projects, thereby effectively blocking development. Similarly, a systematic review by Spyridonidou & Vagiona [
51] emphasizes that stringent site-selection processes can complicate the approval of wind energy projects, particularly when they are not aligned with local community interests or environmental protection.
On the other hand, enabling regulations are designed to facilitate wind energy development by providing clear guidelines and incentives. For instance, Tegou and colleagues [
52] outline a comprehensive environmental management framework integrating technical, economic, social, and environmental factors to assess wind energy sites. This approach not only aids in identifying suitable locations but also aligns with sustainable development goals, thus enabling projects to proceed more smoothly. Furthermore, the work of Mahdy & Bahaj [
53] illustrates how multi-criteria decision analysis can be employed to identify optimal offshore wind sites, thereby promoting development through informed decision-making processes. This includes the integration of Geographic Information Systems (GISs) in site selection, as discussed by Bili & Vagiona [
54]. Gavériaux and colleagues [
55] exemplified how enabling regulations can leverage technology to enhance the efficiency and effectiveness of wind farm siting. These methodologies allow for a more nuanced understanding of potential sites and balance ecological concerns with the need for renewable energy development.
2.2. Wind-Specific Regulation Characteristics
Wind projects typically consist of wind turbines, access roads, and connections to transmission lines. Wind turbines, typically 50 or 80 m, with recent (post-2016) models exceeding 100 m [
56], generate electricity as the wind’s air pressure turns turbine blades. Access roads allow for the construction and maintenance of turbines. Transmission lines enable the transmission of electricity generated by turbines to users of energy. Often, the wind-specific infrastructure can take up only about 10% of the installation space, with a majority of this being the roads for servicing and maintenance [
2], meaning the concrete pad for turbines is not the only siting issue of concern [
57]. Local regulations of wind installations typically focus on two main features: the spatial context of turbines and the technical features of the turbines themselves.
2.2.1. Spatial Context
A primary set of considerations for local wind regulations involves the spatial context of turbine siting. Setbacks are the core method by which a county can dictate how, and to an extent if, a renewable energy installation will be installed by requiring a minimum distance between the wind energy conversion system and other features around it a minimum distance between the wind energy conversion system and other features around it [
9,
37]. As shown in
Figure 1, typical features from which turbines are setback include existing structures, property lines, transmission lines, roads, settlements, and other turbine installations. Additionally, within a single project, turbines may be required to have a certain setback from each other, known as tower density. Setback values can significantly affect the viability of a project proposal. Larger setbacks reduce the land available to install the turbines, make it costly to connect to the grid, and reduce the power density output from a wind farm. Some setbacks may have the effect of severely reducing the land available, making the developer cancel the project proposal altogether [
4]. At the same time, while wind farms require large land areas, and the spaces not directly occupied by the turbines or roads to the turbine area are left free for other uses that allow for multiple economically productive activities simultaneously, such as farming and grazing [
41], allowing the possibility of multiple economically productive land uses simultaneously.
2.2.2. Technical Specifications
Counties may also enact land use provisions that are more technical in nature, generally to address issues perceived as nuisances. Negative impacts associated with wind projects may include the shadow flicker resulting from light disrupted by turning blades, noise to the houses within their vicinity [
13,
58], and a reduction in property values [
59]. Height above ground plays a key factor in the wind generation by turbines but also raises local concerns about the degradation of viewsheds and the rural character of communities [
60]. Height limits may make it more difficult to use this massive resource because taller turbines may capture more energy higher up, where speeds are faster than at lower heights [
61,
62]. Similarly, restricting height could have the unfavorable effect of requiring more turbines to produce the same amount of electricity [
13]. According to Hoen and colleagues [
63], given the existing innovation trends, local governments might mandate greater setbacks to accommodate larger turbines. Nonetheless, bigger turbines might result in a 60% decrease in the amount of land needed, or around 130 turbines per typical wind farm [
13]). Collectively, we classify these four areas of technical considerations: (1) height restrictions, (2) minimum blade clearance, (3) shadow flicker conditions, and (4) maximum noise allowances.
2.3. Factors Driving Local Wind Regulation
Next, we examine factors that may help explain local variation in wind regulation, which together form our conceptual model and drive our core research questions. A growing body of studies investigates the successes and failures of the green energy transition across a range of issues. These include the impact of renewables on land [
41,
63,
64,
65], factors affecting renewable energy generation [
2,
39,
57,
62,
63,
65], the market trends of renewable energy [
12,
66,
67], federal and state policies concerning green energy [
5,
37,
68], attitudes towards renewable energy [
48], policy diffusion between counties [
9], and factors that limit the adoption of renewable energy [
7,
27,
69].
While some states have established policy targets for renewable energy, counties less commonly set corresponding goals, especially in states with the most wind potential. The regulations counties implement are typically influenced by local dynamics [
9,
28,
44]. Few empirical studies examine the interplay of factors leading to different types of regulations adopted by a local government, however. Existing studies typically focus on a single, distinct factor, such as the regulation’s environmental considerations, or provide in-depth case studies of the local political context. Winikoff [
9] models economic factors, assuming counties have a target number of turbines, and makes a regulatory trade-off to optimize this number. The model also draws data from earlier years (2007, 2008, 2010) to predict or explain regulatory outcomes in 2019. Our study controls for the temporal effects and models local factors and their relationship to the regulation adopted. On the other hand, Lerner [
8] attempts to model these local factors, primarily the relationship between developers and cities, and how it impacts the regulations. However, their data have limitations as they show only 27 counties in Kansas have a regulation, while we show 74 counties. In both cases, they also ignore the state moratoria, which supersede the local regulations in their sample.
Data limitations about local regulations across a state or region have long been a challenge in conducting studies that go into the depth of myriad local land use planning issues, such as environmental conservation, the mitigation of natural hazards, the provision of affordable housing, and adapting to climate change; such data limitations have been a barrier in understanding the green energy transition [
70]. Beyond data limitations, renewable energy is a relatively new area of local policy innovation with substantial prior scholarship.
2.3.1. Federal and State Policy Contexts
In the United States federalist system, the Federal government has significant, though not unlimited, power to compel or incentivize state-level action on renewable energy. In turn, states may compel or incentivize local-level action. However, as noted earlier, land use regulation powers essential for renewable energy transitions have typically remained at the local level [
71], as states typically hesitate to impose land use standards on communities, a phenomenon that is especially true in states with high wind potential. Because the empirical dimension of our study focuses on one state at one point in time, Kansas, in 2024, we only briefly reference the federal and state policy context, although future studies that compare county regulations across time or across states should account for these factors. In recent years, the federal government has increasingly sought to incentivize wind energy development [
12,
72,
73,
74]. The Infrastructure Investment and Jobs Act of 2021, often known as the Bipartisan Infrastructure Law (BIL), and the Inflation Reduction Act of 2022 (IRA) are the most recent laws that Congress has approved that directly affect renewable energy [
75]. Production tax incentives, offering credits for each kilowatt-hour of electricity sold to an unaffiliated party for 10 years once the facility is put into service, provide perhaps the biggest incentive for wind installation [
12]. However, investment incentive credits are provided to wind developers to cover some of the capital input costs at the initial stages of project development and thus may not have much impact on county-level decision-making. Developers also need to submit an environmental assessment statement in accordance with the National Environmental Policy Act (NEPA) to evaluate the potential environmental impacts of the proposed project [
76], while some sites require permits from agencies such as the Bureau of Land Management, Federal Aviation Administration, and U.S. Fish and Wildlife Service often require a permit or specific project specifications [
12,
77]. At the state level, renewable energy portfolio standards (RPS) establish targets for the percentage of total energy that electric suppliers must derive from renewable sources, thus serving as incentives for their development [
78]. The state of Kansas is one of the few states with an expired RPS, which it did after meeting its target of 20% by 2020. All states have utility commissions, and some have regulatory requirements for the development of renewable energy projects, especially on siting or permitting [
37]. Some states have model regulations that local jurisdictions use to guide the enactment of local regulations. Again, for our purposes, all of these considerations hold constant within Kansas.
2.3.2. Biophysical Factors
Two main biophysical factors shape local wind installation regulation. Most obviously, the potential for an area to generate enough wind to be economically viable. Wind energy projects are most viable where the wind blows strongly and consistently, whether onshore (i.e., on land) or offshore (i.e., on water and beyond the scope of this study). In the United States, the onshore wind resource is predominantly available in the middle belt of the country, running from North to South [
39], covering states such as North Dakota, South Dakota, Nebraska, Kansas, Iowa, Oklahoma, and Texas. Interrelated is the availability of land, typically in rural areas, sufficient for a concentration of turbines from which energy can be generated and transmitted; that is, the production of electricity from wind energy is a land-use-intensive activity [
9,
41,
79,
80]. Turbines installed on the ground require considerable space due to safety issues while also maximizing energy generation [
81]. The National Renewable Energy Lab (NREL) indicates that 30 acres of land is needed to produce 1 megawatt of electricity [
39], and the US will need land nearly the size of Texas to meet the ambitious goal of the net-zero transition by 2050 [
82]. Thus, the availability of wind potential and available land presents the first set of biophysical challenges to meet the rising demand for wind energy [
65].
A second biophysical factor Involves whether wind installations negatively impact other environmental concerns [
27,
82]. A site might have high wind energy potential but also comprise a valuable ecological habitat. Such concern led Kansas, in 2011, to create (and in 2020 to reaffirm) a multi-county Tallgrass Heartlands Wind Moratorium area to preserve the “unique prairie ecosystem” [
83]. This mirrors concerns about tradeoffs between wind and agriculture in agriculturally productive areas with high wind potential.
2.3.3. Infrastructure Connectivity Factors
New wind projects in high wind potential regions like the Great Plains can be hindered by transmission constraints, limiting the ability to transmit electricity to areas of high demand. Research shows that the availability and proximity of the electricity transmission grid influence where developers choose to site their projects [
42,
84,
85]. Developers prefer areas close to the necessary voltage transmission lines connected to utility providers. Due to wind’s intermittent power generation and the nature of current, renewable energy power must be converted before being connected to the main grid, which complicates connectivity from a technical and, potentially, a land use standpoint [
86]. Thus, for the purposes of understanding county regulations, proximity to transmission capacity may be an important influence (land regulations, local opposition, and right-of-way permit requirements have delayed the construction of renewable energy projects [
87]. In 2020, about 750 GW of renewable energy projects faced setbacks due to transmission limitations, causing concerns from grid developers about underutilization [
86,
88].
2.3.4. Community Socio-Economic Characteristics
A myriad of social and economic factors shape local planning and land use regulation, with wide variation depending on the composition of the community and whether the planning topic is considered to benefit the community [
89,
90,
91]. Typically, places with more college-educated residents, which often are more populous communities, are likely to push for planning that addresses their environmental concerns [
92]. Community wealth, whether considered in terms of median incomes or home values, can influence local planning by increasing fiscal resources to hire more in-house or consulting planning capacity. Each of these factors has the potential to shape whether and how counties regulate wind projects.
Additionally, economic factors specific to energy generation may influence how a county regulates new wind projects. Many communities with high wind potential may have legacies of fossil fuel production or processing. Fossil fuel extraction often carries local fiscal effects that are valuable to local jurisdictions, whether due to job creation or revenue like property taxes that support schools, roads, and the provision of public services [
93]. Shifting to renewable energy sources, especially if linked rhetorically or substantively to reductions in fossil fuels, may become a local impediment to wind installation. Likewise, in rural areas, dependence on agricultural production and processing can dominate the local economy. The extent to which major farm interests understand wind installations as complementary or competitive may shape county regulations.
2.3.5. Local Political Context
Local politics is also another factor that has been found to play a role in local green energy planning [
9,
28,
44]. Prominent considerations include economic benefits to the community [
18,
94], the existence and abundance of renewable energy resources [
79], political opinions and community attitudes [
27,
95] a state of grid infrastructure [
96], and environmental considerations [
82]. Instances of local governments having highly restrictive land-energy regulations, possibly more so than their federal and state counterparts, were noted early in the initial years of renewables development [
46]. Over time, some local officials have strived to ban wind projects, while others have aggressively promoted them [
3].
Opposition to renewables is in both conservative and liberal areas [
14]. Core values and deeply entrenched policy orientations influence local decision-making at the local level, even if partisan politics are less dominant [
64,
97]. Objections to wind development proposals may extend beyond “NIMBY” (Not in My Backyard) concerns and often reflect concerns about participation and authority during the decision-making process [
7]. Evidence suggests that those who object to wind energy in their areas often lack first-hand experience [
47]. Thus, even if directly impacted landowners have an agreement with a developer to install wind turbines on their property, public participation requirements at the local level permitting stage may result in objections from residents and stall or kill a project [
98]. A recent case study of the High Banks Wind Project, a large wind project situated in the counties of Republic and Washington in Kansas, suggests that the communities’ opposition to wind development was influenced by local mistrust and, to some extent, false and misleading information [
99].
Meanwhile, more liberal areas may more readily accept land use regulation and broadly support the green energy transition but worry about tradeoffs with other local environmental issues, like habitat conservation or social issues, such as affordable housing. In virtually all contexts, the green energy transition is highly political with local leaders facing intense pressures, up to and including physical threats [
98,
99]. Familiarity with renewable energy sources matters as well, as local leaders push for the adoption of ordinances regulating wind in instances where they have interacted more with the developers and have seen neighboring counties adopt them [
8,
100]. Pierce and colleagues [
27] noted that high social capital was related to fewer turbine installations in the counties in Kansas and posited that this higher social capital is likely used to drum up opposition to renewable projects.
2.3.6. Planning Capacity
Developing an appropriate renewable energy siting policy at the county scale requires familiarity, if not expertise, across a broad swath of knowledge applicable to local land use regulations. Prior studies identified the availability of planners during the planning process as a critical component in land use planning in general [
34]. Planners improve the capacity of local authorities to make sound decisions by providing expertise and information on the issues being addressed [
101]. Local governments, particularly in rural areas, have been found to be lacking in professional expertise that would enable them to plan for and regulate renewable energy developments effectively [
60]. Local planners often bear responsibility for reviewing and making recommendations on wind installation proposals for adoption or denial by planning commissions and county commissions, which often comprise volunteers and other non-experts [
90]. As is true for the general public, a lack of prior experience with wind regulation among planning professionals can complicate drafting, approval, and implementing county regulations [
102]. The lack of widespread expertise, as well as basic capacity in smaller counties, may increase the importance of policy diffusion, as neighboring counties enact similar regulations to those surrounding them, especially if those counties have the capacity to draft their own regulations [
58].
2.4. Conceptual Framework and Research Questions
Collectively, the literature reviewed above leads us to present the conceptual framework shown in
Figure 2. Federal and state policies, socio-demographic factors, biophysical factors, power infrastructure, planning capacity, and local political factors may drive the adoption of local wind regulations and variations in the types of regulations adopted. In turn, this framework leads us to develop research questions from the conceptual framework (
Figure 2), as follows:
- (1)
How do regulations of wind facilities vary at the county level?
- (2)
What factors explain the variation across county wind regulations?
2.5. Research Design and Methodology
We employ a comparative research design using primary data collection and couple the primary data with secondary data sources in multivariate regression modeling to answer our two questions. The unit of analysis for our study is the county, focusing on the regulations adopted to enable, block, and otherwise shape the installation of wind generation capacity. Collecting county-level regulations and analyzing their contents requires considerable time and effort, and thus, we focus on one state with high wind potential and an actively evolving local regulatory context. Our approach allows us to eliminate state planning and energy policy as a confounding factor, while also providing a foundation for future extensions and comparisons across states.
2.5.1. Why Kansas
Kansas is the nation’s fourth-largest wind producer and is the third largest in terms of share of renewable energy sources [
103]. Kansas ranks first in the country in terms of wind energy share of total renewable energy production at 99.4% wind, with solar and other sources comprising the remainder. In recent years, more than 40% of electricity generation in the state has come from wind. Focusing on Kansas thus allows us to understand the role of local regulation in one of the key states for a green energy transition, although it may limit generalizability to states with lower wind potential.
Kansas’ land use and energy policy context highlights the importance of local land use regulation, as well as the dynamic and contested nature of the green energy transition. The State of Kansas grants counties and municipalities the authority and autonomy to enact regulations concerning land use within their jurisdictions, under which renewable projects must be approved. Additionally, at the state level, Kansas went from actively supporting renewable sources of energy generation at the state level, such as having a Renewable Portfolio Standard, to a state posture of leaving renewable energy development to the existing market dynamics and local preferences [
104]. Stokes charts how a combination of fossil fuel industry lobbying and local resistance to wind installations drove this shift, creating a complicated local policy landscape in which some counties sought economic development benefits associated with wind installations and others sought to block wind installations for a mix of economic, private property rights, and anti-climate change rationales.
2.5.2. Primary Data Collection on County Wind Regulations
Our team visited the government website for each of the 105 counties in Kansas to obtain wind regulations, downloading the relevant documents and web links. In cases where regulations were not obtainable online, we contacted local governments directly to obtain the relevant regulation or affirm that no such regulations had been adopted. Our data were collected and coded between January and July 2024, which establishes August 2024 as the point in time for our analyses.
We coded four main types of regulatory mechanisms being used: the incorporation of wind regulation standards in an existing zoning code, a stand-alone wind regulation code, a moratorium on wind installation (ban or temporary), and one-off development agreements between a county and a wind developer for a specific installation project. A fifth category of the regulatory mechanism includes a state-level moratorium on wind installation, the Tallgrass Heartland Wind Moratorium, which covers all or parts of 12 counties for the purpose of “conserve[ing] Kansas’ unique prairie ecosystem, vital to native wildlife, tourism, education, and local ranching economies” [
83]. We characterize these five types of regulatory approaches as enabling (zoning, wind-specific, and development agreements) or blocking (state and local moratoria). As previously noted, however, the specific features of zoning and wind-specific ordinances can be crafted to functionally ban wind projects, for example, by setting such large setback distances that no site in the county could possibly meet the setback requirements. The implication here is that our measurement likely underestimates the extent of local blocking actions. Finally, some counties have taken no action to regulate wind installations to date.
In addition to noting the type of regulatory mechanism, our team read the relevant regulations and coded 11 distinct types of sitting characteristics, covering topics including distance-based setbacks, turbine heights, minimum lot sizes, and more, in line with
Figure 1 in the literature review (see
Appendix A for more detail).
2.5.3. Creating the Kansas Energy Transition Atlas
We created the Kansas Energy Transition Atlas (KETA), a publicly available, web-based Geographic Information Systems platform to provide access to the primary data described above. Additionally, we collected secondary data from federal, state, and non-profit organization sources to enrich the ability of users to explore, understand, and analyze the myriad factors shaping the green energy transition in Kansas. An overview of the data from secondary sources includes the following categories: political factors, such as voting patterns; sociodemographic factors, such as median home values, education levels, and environmental (in)justice indicators; biophysical factors, such as wind potential, oil and gas production, and environmentally sensitive areas; energy infrastructure, particularly transmission lines; and planning capacity, especially the presence or absence of a local planning director. Detailed explanations for how each data set was obtained and converted to be accessible are in the notes. We utilized ArcGIS Pro to convert biophysical data from raster to vector format and then performed pairwise intersection processing using the county feature layer. The resulting intersect layer underwent summary statistics processing to find the sum, mean, median, maximum, and minimum values, which were then spatially joined to the counties layer and exported. The process was similarly applied to oil and gas wells’ point data and transmission line data to analyze cumulative production and capacity. However, for the transmission layer, the summary statistics were configured to be a function of the length and voltage capacity, so that the highest capacity represented counties with more lines and higher carrying capacity. This was performed to control for instances where a county might have low-voltage lines that do not have enough capacity for carrying large amounts of power from wind farms. The KETA provides users the following capabilities: (1) exploring county wind regulations, including specific siting characteristics in the regulations, as well as direct access to the relevant document (pdf or weblink) and contact information for the relevant local agency; (2) generating maps of selected variables (displayed in selectable layers) and overlays, with the user only need to create a map title; and (3) as described below, analysis of quantitative relationships between variables included in the KETA. A detailed user guide helps users navigate the platform, and the team is in the process of complementing the county wind regulation data with data on county solar regulations (a slower-developing policy domain in Kansas).
2.5.4. Descriptive and Inferential Statistical Methods
Our first research question regarding the patterns of variation in county wind regulation is answered with a combination of descriptive statistics and maps generated from the KETA. We chart and map the following data: (1) the presence or absence of any county wind regulation; (2) variation in the regulatory approaches used (zoning, wind ordinance, development agreements, moratoria); and (3) variation in the specific siting characteristics used to influence wind installations.
Our second research question regarding factors that explain variation in county wind regulation is answered with a series of multivariate regression models. Two main regression models presented in the findings answer our questions, although we ran additional models for the purposes of sensitivity analysis. The first model uses binary logistic regression to explain the presence or absence of any wind regulation (a binary dependent variable with an n of 105 counties), based on a combination of political, sociodemographic, biophysical, power infrastructure, and planning capacity factors (independent variables descriptive statistics in
Appendix A). To improve model interpretation and reduce large coefficient values, some variables were rescaled. Median Income and average farm income were divided by 1000, population divided by 1000, cumulative gas and oil production divided by 100,000, area covered by environmentally sensitive land and valuable ecosystem divided by 1,000,000, and transmission potential divided by 1000. The main focus of the analysis was the significance and direction of relationships rather than the absolute magnitude of the coefficients. Thus, the model still retains the validity of inference based on coefficient signs and
p-values, as these are unaffected by the linear rescaling.
The second model also uses binary logistic regression to explain whether the type of wind regulations adopted is a blocking or enabling regulation (a binary dependent variable with an n of 74 counties that have taken one of the five approaches), using the same set of independent variables as predictors. Diagnostic measures of model fit are presented along with the model estimates, standard errors, and p-values.
We recognize inherent limitations in a single-state approach with a limited sample size (n = 105 counties), which may limit generalizability. Additionally, some factors that may predict local policy adoption, such as aspects of the planning process used to generate the regulations, the idiosyncrasies of local county officials’ views toward wind energy, and the strategies of the private wind developers, are beyond our ability to measure at this time. Likewise, our research provides a single-point in-time view of the regulatory environment, which prohibits any tracing of policy evolution over time. Due to the limited number of counties with influential setback regulations, statistical modeling to assess relationships with predictor variables was not feasible. Each of these limitations offers directions for future research.
Interpretation of binary logistic regression results in wind energy regulation studies requires the consideration of both statistical significance and effect sizes. While
p-values indicate the presence of relationships between variables, effect sizes reveal the magnitude and practical significance of these relationships, providing an important context for policy applications [
105,
106]. In the context of county-level wind regulation, this understanding goes beyond simply identifying which factors (such as median household income, population, or transmission line proximity) have statistically significant associations with regulatory adoption. Instead, recognizing the impact of sample size can quantify and contextualize the strength of these relationships through measures such as odds ratios, which provide stakeholders with clearer insights into the practical implications of their findings [
107].
When examining the factors that influence whether specific places can adopt enabling or blocking regulations, the integration of effect sizes becomes particularly important for understanding the relative impact of different variables. For instance, while the presence of valuable ecosystems shows statistical significance in predicting blocking regulations, the practical interpretation of this relationship requires an examination of effect magnitudes to understand its policy implications [
50]. This approach aligns with recent methodological advances in environmental policy research that advocate for more nuanced interpretations of logistic regression results [
51]. Such an analysis enhances the statistical rigor of the research and provides more actionable insights for policymakers and stakeholders involved in wind energy development.
3. Findings
Our findings answer our two research questions about variations in county wind regulations and factors explaining that variation. As described below, we found that 70% of Kansas counties have wind installation regulations in effect, with clear spatial patterns apparent in our maps. Among those counties, we find wide variation in the types of regulatory approaches being used. However, patterns of spatial variation are more nuanced, as is true for the variation in the specific siting characteristics found in the regulations. Our regression modeling identifies that socioeconomics, infrastructure, and biophysical context are associated with variation in county regulations, but no relationship to political factors and wind-generating potential.
3.1. Presence of Wind Installation Regulations
Out of 105 Kansas counties, 74 have wind regulations in place, which amounts to 70.5% of the total. As shown in
Figure 3a,b, the counties with no wind regulations generally align into two spatial groups: a handful of eastern counties, mostly along the border with Missouri. The second cluster is western counties, especially in northwestern Kansas and along the Colorado border.
In terms of the types of regulatory approaches taken (
Figure 4a,b), we note the wide swath of counties in east-central Kansas subject to the Tallgrass Heartland Wind Moratorium (THWM). These 11 counties comprise 15% of the 74 Kansas counties with some form of wind regulation. Again, this swath of counties prohibits wind installations based on state activity that was initiated in 2011, reaffirmed in 2020, and tends to have bipartisan support. Five additional counties are part of the THWM and have zoning regulations. The six additional counties with moratoria (8% of the 74 counties) consist of three counties along the I-135 corridor from Wichita to Salina, just west of the THWM swath, as well as Shawnee County, which contains Topeka and is just east of the THWM, and two lower population eastern Kansas counties. Together, these counties represent the group we consider to be engaged in blocking actions, a combined 19 counties, which is nearly 20% of the 105 total counties.
In terms of the counties opting for enabling actions, we find zoning regulations to be the dominant approach, with 30 of the 74 counties (40%) embedding wind standards in their existing zoning code. These counties span the state from east to west and north to south, showing no clear clustering. Nineteen counties (26%) rely on one-off development agreements with private wind developers to set standards for installations. Like the counties using zoning, these counties span the state north to south and east to west, with no clear clustering. The three counties with wind-specific regulations (4%) are in southern Kansas but do not border each other. Together, these counties amount to 52 counties (or at most 50% of all Kansas counties) that are taking enabling actions, as some of the zoning and wind-specific ordinances may functionally block wind projects.
3.2. Characteristics of Wind Installation Regulations
The patterns of specific characteristics of wind installation regulations are even more varied among the 74 counties with regulations in effect (
Table 1). More counties focus on spatially oriented characteristics of installations than technical characteristics. For example, environmental considerations—the key factor identified for the THWM—are present in more than half of the counties (41 or 55%), even as minimum lot sizes and minimum distances from settlements are less common. Project size limitations also abound, with road, structure, and property line setbacks used in roughly half of the counties. Nuisance considerations and technical considerations, while present in many counties, are not typical. In terms of spatial distribution, the patterns shown in
Figure 5a–c basically reflect the same variation as the zoning and wind-specific regulations, as one-off development agreements do not necessarily set forward-looking policy standards.
Setback standards exhibit limited variation across most counties. However, a small number (approximately seven—Cherokee, Harvey, Bourbon, Neosho, Reno, Kearny, Reno) adopt significantly larger setback distances that deviate from the broader pattern. Moreover, only 36 counties have at least one documented setback regulation, further constraining the sample size available for modeling the factors associated with variation in setback strictness.
3.3. Explaining Factors Shaping Wind Installation Regulations
We begin by explaining factors associated with the existence of any wind installation regulation, which 74 counties have in place.
Table 2 shows the results of the first logistic regression modeling; the model includes all 105 counties (n) and exhibits strong model performance in terms of pseudo-R-squared, explaining more than half of the variation in the data (0.64).
The model indicates that median household incomes (p = 0.004), proximity to transmission lines (p = 0.017), and overall population (p = 0.058) are positively associated with a county having some sort of wind regulation. Meanwhile, high average farm income (p = 0.010) and the presence of a county planner (p = 0.029) are negatively associated with county wind regulations. Notably, partisan voting, fossil fuel production, and wind energy potential are not statistically significantly related to county wind regulation at commonly accepted levels.
The modeling of factors associated with whether a county wind regulation focuses on blocking (moratoria) or enabling (zoning, wind-specific, development agreement) wind installation also exhibits strong model fit (pseudo-R-squared of 0.78). This model includes the 74 counties with some sort of regulation, of which 22 are considered blocking and 52 are considered to be enabling. Median household income (
p = 0.022) and overall population (
p = 0.059) are associated with enabling regulations (positive estimates), similar to the adoption of any type of regulation. Again, average farm income (
p = 0.014) is associated with blocking legislation (negative estimate). However, the main driver of a blocking regulation appears to be the presence of a valuable ecosystem (
p = 0.008), which fits with the state intervention to create the Tallgrass Heartland Wind Moratorium. Other factors, like fossil fuel production, partisan voting, and proximity to transmission capacity, are not statistically significantly related to blocking or enabling at commonly accepted levels. (We also analyzed this relationship without the valuable ecosystem variable and found that the direction of relationships holds for other variables, although with fewer variables being significant. We replaced the valuable ecosystem variable with key environmental areas for each county and ran the model. See
Table 3b).
4. Discussion
Our findings provide clear answers to our two research questions, and from the answers, we glean numerous insights of importance for scholarship and practice. First, as expected, our descriptive analysis shows wide variation in the county-level wind regulation landscape. Like many aspects of land use regulation, we see a ‘patchwork quilt’ of approaches that evidence the centrality of local control when it comes to the use of land in the United States. The variation plays out across three dimensions: whether counties have taken any type of action yet, whether the actions taken are enabling or blocking wind installations, and what array of specific characteristics comprises the regulations. Second, the regression modeling provides robust predictive power for the presence of county wind regulations and whether those regulations tend towards enabling or blocking wind installation. The wide variation in a dynamic policy realm suggests that Kansas is in a tumultuous phase of energy development at the time of this study.
We see two types of counties that have not yet engaged in wind regulation. The smaller group consists of counties along the eastern border with Missouri, which, comparatively speaking, have less wind potential than much of the rest of Kansas. We discourage others from interpreting these counties as irrelevant, however, as even the lowest wind potential areas of Kansas still have more generation potential than almost any county in the eastern half of the United States. We expect that these counties will likely face pressure to adopt regulations in the near future, whether due to proposals for wind facilities from developers or to proactive policy pushes within the county. The larger group of inactive counties (as of August 2024) tends to be in western Kansas, especially along the border with Colorado and in northwestern Kansas. Compared to other counties in western Kansas, the inactive counties tend to have smaller populations, are less wealthy, and are somewhat farther away from the major energy transmission lines.
The results from the associated regression model affirm this dynamic. The indication that the presence of a county planning director is negatively associated with the adoption of regulation is counterintuitive. However, this finding may be an artifact of variation in planning capacity in the inactive counties, as the eastern counties that are inactive may be likely to have planning staff. Together, these findings point to the question of whether smaller counties farther from transmission lines, which are often in desperate need of economic development opportunities to help stem population decline, may be left behind in the green energy transition. This concern may have even greater import outside of Kansas, in Great Plains counties ranging from the Canadian border in North Dakota and Montana to the Mexican border in Texas and New Mexico.
Interpreting the patterns of enabling and blocking regulations presents a more nuanced narrative. First, in 2011, the state prioritized conserving environmentally sensitive areas by adopting the Tallgrass Heartland Wind Moratorium across the Flint Hills region of Kansas. Other states may also choose to take such action to preserve ecologically sensitive areas, which may reveal deep tensions between local environmental goals, particularly protecting endangered ecosystems and vulnerable species, and national and global environmental goals of expediting the renewable energy transition.
Interpreting local actions to block wind installations also points to place-based context and the need for additional research. Do the actions of counties in the I-135 corridor between Wichita and Salina and in the Topeka area of Shawnee County point to spillover concerns about ecological conservation adjacent to the Flint Hills? Or, perhaps, do the actions of these higher-population counties suggest more of a Not-In-My-Backyard (NIMBY) dynamic among residents on aesthetic grounds? (Two interesting exceptions are Douglas County and Johnson County in eastern Kansas, each with larger populations and wind potential, though lower potential than counties in Western Kansas. For now, the counties have pursued what we measured as enabling regulations, although debate continues as to whether the standards amount to a ban). Case study research holds the potential to shed light on these nuances, particularly the role of public discourse in planning processes and the specific features of local political climates, given that partisan politics does not appear to be a factor.
Around half of Kansas counties, at most, fall into the group enacting enabling regulations. These counties tend to be more populous and have a higher median income, although we must remember that those tendencies are in reference to the rest of the state, not the nation. The finding that counties with larger average farm incomes are less likely to adopt enabling regulations points to the need for a better understanding of the interaction between agriculture and renewable energy industries. Although our data do not include a temporal dimension, we suspect that future research will show that development agreements often precede the adoption of wind-specific provisions in zoning regulations or stand-alone wind regulations. We also acknowledge that stringent setback regulations may reduce the favorability of certain locations for wind energy development. Future research that develops a detailed stringency index for these regulations, especially for specific standards that directly impact developers, would provide a more comprehensive understanding of their implications.
Overall, we see a general pattern that will be interesting to monitor over time. Among the counties not subject to state-level moratoria, less populous counties farther from transmission capacity (northwestern Kansas) or of prime wind generation areas (eastern Kansas) tend not to have taken action yet. At the other end of the spectrum, more populous counties seem to tend toward blocking action. Most Kansas counties are between these two extremes of largely rural counties that appear to be pursuing enabling legislation, presumably to foster economic growth. Yet, these counties vary widely in the type of regulatory approach—zoning, wind-specific regulation, and development agreements—and in the specific siting characteristics.
Our findings highlight the rapidly evolving and dynamic nature of the green energy transition, overlaid on the United States’ longstanding tradition of local land use control. All manner of interested parties in the renewable energy transition seek more clarity and control, although often coming from very different philosophical, economic, and social perspectives. At the very least, the ‘patchwork quilt’ of regulations requires tremendous effort from interested parties to monitor and engage with varied local processes. This challenge holds true whether one is a county official seeking to develop regulations, energy developers seeking to build a wind project, or residents and advocates seeking to shape local regulations or influence decision-making on project proposals.
Before concluding, we also feel it is important to iterate that the only state-level intervention in renewable energy siting in Kansas—the THWM—has been a blocking action. That is, to date, the state has not opted to preempt or otherwise limit local land use control over wind energy development. A few states have recently modified the role of local governments in renewable energy siting, raising questions about whether and how and under what circumstances states may intervene on traditional land use regulation for national and global aims.
5. Conclusions
Our research has sought to answer key questions in the rapidly evolving renewable energy transition policy landscape. With Kansas, one of the vanguard wind energy generation states, as our focus, we have examined the variation in local land use policies related to wind development. We assessed factors explaining whether counties have regulations that enable or block wind generation capacity, an issue identified by green energy developers and media outlets as a major barrier to meeting national and global goals to transition away from fossil fuels.
Our findings point to a highly varied local regulatory context in Kansas, with roughly 70% of counties currently regulating wind installation through land use controls. Of those, between ¼ and 1/3 have adopted blocking regulations (or are subject to a state-level moratorium based on environmental rationales). That leaves just 50% of Kansas counties adopting some form of enabling legislation, although the approaches vary widely, including wind provisions in existing regulations, adopting stand-alone wind ordinances, and one-off development agreements. Our regression modeling suggests a non-linear pattern of the least populous and least wealthy counties, especially those farther from transmission capacity, not having yet taken action. Notably, some counties have adopted moratoria, and others are in the midst of contentious policy debates and battles. The broad middle contingent of counties seems poised to facilitate wind installations, although those with larger average farm incomes appear less receptive.
Our study points to implications for states and local governments in areas with high wind capacity, not least because a huge menu of options exists. At the very least, the ‘patchwork quilt’ of regulations in this ‘wild west’ landscape poses challenges for all parties interested in clarity, especially those eager for an accelerated green energy transition. State-level entities may choose to develop model regulations for local officials to consider, as well as training programs highlighting the range of options available, which are likely needed in an emergent field like wind generation. In other countries with a multi-level framework for land use regulation, similar steps may assist sub-national officials tasked with permitting wind installations. We hope the Kansas Energy Transition Atlas, a publicly available, web-based Geographic Information Systems tool, aids all parties to understand this context better and may serve as a model for sub-national governments for tracking and publicizing regulatory activities. We also hope the KETA and the analyses we present here advance future research into activities in other states, activities over time, and especially place-based factors that so often shape local land use regulations that enable or constrain broad societal goals.
