Traditional capital construction will not only seriously constrain the transformation and upgrading of China’s economic structure but will also lead to a high probability of recurrence of new types of ecological risks, which will cause the relevant industries and enterprises to miss development opportunities and face greater challenges in achieving green development. Therefore, the development of “new infrastructure” construction and the promotion of the rapid development of the 5G network, automobile intelligence, new-energy vehicles, artificial intelligence, industrial Internet, and other industries can not only stabilize the traditional real economy but also significantly reduce the cost of sharing fixed assets, energy consumption, and environmental protection through the virtualization and structuring of data resources. It not only meets the urgent demand for data industry green development in some key areas of new infrastructure but also provides the necessary support for how to introduce the rule of law and other institutional constraint tools for data industry green development in this scenario.
3.1. Developing Ultra-High-Voltage Smart Grid
The rapid development of the economy requires the consumption of a large amount of energy. As a fast-developing country, China’s energy consumption ranks second in the world, resulting in many Chinese cities reaching the maximum emissions of air pollutants. The adjustment of the energy structure, prevention, and control of air pollution has been imminent. The construction and operation of an ultra-high-voltage power grid will greatly improve the situation. At the end of 2017, “four AC and four DC lines” in an ultra-high-voltage (UHV) smart grid were all put into operation. The North China Power Grid initially formed an ultra-high-voltage AC grid, with Beijing, Tianjin, Hebei, and Shandong province receiving a capacity of 32 gigawatts and the Yangtze River Delta receiving a capacity of 35 gigawatts, which can reduce the emission of 960,000 tonnes of sulfur dioxide and 530,000 tonnes of air pollutants annually. A reduction of 960,000 tons of sulfur dioxide, 530,000 tonnes of nitrogen oxides, and 110,000 tonnes of soot per year and the effect of the prevention and control of air pollution are remarkable [
9]. With clean energy from the west and north boosting the transformation of energy consumption in the east and central regions, UHV has become an important channel for China’s economy to realize green development and it is also a representative field for the digital upgrading of new infrastructure in the future. Among them, the digital power grid built with the help of 5G digital technology is the most important.
The UHV smart grid is also known as “Grid 2.0” in China. The most important features are the “data flow”, “power flow”, and “transaction flow”, which are highly intertwined and can better improve the power delivery and use of power, reduce the probability of failure, shorten the fault maintenance time, improve the security of the entire power grid and its flexibility, and minimize energy consumption and electricity costs. Under the concept of green development, the smart grid will further realize the digital upgrading of the existing power system through the four links of power consumption information collection, automated intelligent power distribution, precise load control, and distributed power supply:
First of all, electricity consumption information collection. Through the newly constructed electricity consumption information collection system, it can timely, completely, and accurately grasp the data of users’ electricity consumption. The data can be used as the basis for charging users for electricity consumption and automatically controlling the power outages and power delivery of functional users. Secondly, implementing smart power distribution. It integrates data transmission, precise control, equipment management, and other technologies and realizes intelligent judgment, analysis, fault location, fault isolation, power supply restoration in non-faulty areas, and other operations through peer-to-peer communication between terminals to make the whole fault-handling process fully automated and minimize the time and scope of faulty power outages. Thirdly, achieving accurate load management. The power load management system integrates modern management, computer applications, automatic management, and digital technology to realize various functions, such as power marketing monitoring, power marketing management, data collection, and network connection. Compared with the traditional power distribution network to disconnect the entire distribution line when the load is removed, precise load management is more flexible and intelligent.
Finally, implementing distributed power supply systems. It is a method of energy supply based on the user side, mainly including wind power, solar power, electric vehicle charging stations, energy storage equipment, and microgrids. In addition to saving the investment cost of the transmission grid, distributed energy can also improve the reliability of the entire power system. For example, in the event of large-scale damage to the power network, distributed energy can be isolated or used to form a microgrid to provide an emergency power supply to transportation hubs, hospitals, radio and television broadcasting, and other important facilities.
In the various application scenarios of a digitalized ultra-high-voltage smart grid, the business requirements under different scenarios have large differences, and these differences are mainly reflected in the requirements of different data technology indexes. Although the design and construction of the smart grid has better met the green development requirements, at the data level, the virtualization of power facilities and data standards are still not uniform. At present, there is a significant lack of data policies and regulations to help electric companies to amend and guide the technical architecture of digital grids according to the differences in technical indicators. This is especially true in regards to environmental protection in the construction of ultra-high-voltage facilities and for managing high-quality and accurate control of the data flow system to regulate green development. There is an urgent need to introduce a rule of law program that can meet the needs of multiple scenarios and differentiated data so as to achieve the goal of green development under diverse data application scenarios, such as digitalized ultra-high-voltage power grids.
3.2. Developing Next-Generation Green Data Centers
Against the backdrop of rapidly growing energy and land costs, improving PUE (Power Usage Effectiveness) is one of the core indicators for future data center construction [
10]. The new generation data center is inevitably green and sustainable, which can achieve the full use of energy and space resources and create a sustainable computing environment for data center service providers. In next-generation data centers, data center service providers will be equipped with a large number of energy-efficient servers, eco blade servers, and energy-efficient storage devices and use new power components, power capping, heat intelligence, and other technologies to solve the problems of traditional data centers, and the aim is to realize the seamless integration and management of heat dissipation, power supply, and computing resources [
11]. In the context of “new infrastructure” construction, a green data center has become the common goal of new-generation data center construction. Currently, newly built green data centers present the following outstanding features.
Firstly, developing according to circumstances. For example, in the Chinese eastern coastal areas, high-energy-consuming equipment uses liquid circulation cooling, and insulated coolant is utilized instead of air-cooling. This means no fans or air-conditioning or other cooling equipment is required, and a lot of space is saved, which is also the most efficient way to reduce the PUE at present. Secondly, improving the process and accelerating innovation. The innovation of green processes and technology can save resource consumption, reduce environmental pollution, and guide science and technology in the direction conducive to the development of a green economy; the improvement in process and technological innovation is aimed at reducing the load energy consumption of mechanical data equipment, refrigeration energy consumption, and equipment energy consumption.
As a representative field of new infrastructures, the construction of data centers has been plagued by environmental issues such as excessive energy consumption, and adherence to the principle of green development has become the consensus of society. Although there is no accurate and authoritative definition of a green data center, the evaluation index of green data centers can be clarified indirectly.
At the policy level, in 2014, Beijing took the lead in introducing the local standard “Data Center Energy Efficiency Grading” (DB11/T 1139–2014) [
12] and has been gradually promoting the evaluation of green data centers in Beijing since then; in 2015, the Ministry of Industry and Information Technology, the State Administration of State Organs Affairs, and the National Energy Administration issued the “Pilot Program for the State’s Green Data Centers”, whose main evaluation indicators include the energy efficiency level, carbon emissions, water resources, hazardous materials control, disposal of waste electrical and electronic products, management systems, etc. Green data centers are required to use green energy, realize green procurement, guarantee green operation, and ensure green disposal. On the technical level, in 2014, China’s Open Data Center Committee (ODCC) and The Green Grid Committee (TGGC) jointly carried out a green-level assessment of data centers in China, and the assessment indexes involved three dimensions of energy efficiency, energy-saving technology, and green management; in 2015, the Ministry of Housing and Urban-Rural Development issued the Technical Rules for Green Data Center Building Evaluation, which gives specific guidelines for data centers to carry out green building evaluation according to the Green Building Evaluation Standard (GB/T50378-2014) [
13]; in 2018, the Chinese Institute of Electronics issued the group standard T/CIE 049-2018 “Green Data Center Evaluation Guidelines” [
14]; and in 2019, the Architectural Society of China released the group standard T/ASC05-2019 “Green Data Center Evaluation Standards” [
15].
Combined with the below evaluation indexes, a green data center can be defined as a data center that minimizes the consumption of resources and environmental impact from construction, equipment, and management under the premise of guaranteeing services, security, and reliability (
Table 1). In other words, the existing policies, regulations, and industry standards for the construction of green data centers are more inclined to focus on the hardware aspect. According to the data published by the Ministry of Industry and Information Technology in the National Data Center Application Development Guidelines (2018) in 2019, China’s data centers are becoming more and more perfect in terms of hardware construction, and new data centers, especially large and mega data centers, are gradually shifting to the western part of the country as well as to cities around the north, upstream, Guangzhou, and Shenzhen. Data centers in Inner Mongolia, Hebei, Guizhou, Ningxia, and other regions with sufficient energy and suitable climate conditions account for more than 30% of the total number of racks in use. Based on this, the past relevant policies on green data center hardware construction have become more restrictive. Soft system-level innovation will be the future of green data centers and even new infrastructure in other areas to break through the environmental bottleneck to become the primary choice. However, the reality is that, while local data industry development or digital economies vary in importance, local laws and regulations related to green development have been issued to promote the development of big data or a digital economy, which is relatively limited. Further, specific regulations for the green data center of this specific area are also limited. In the face of the rapid emergence of green data centers, it is urgent for national and local governments to change the direction of green development policies and regulations.
3.3. Green Cloud Platform
Promoting the development of industrial Internet is a huge and complex systematic project, which requires high requirements of the overall planning and ecological layout and needs to emphasize the system design, supply–demand matchmaking, cross-border cooperation, energy saving and efficiency enhancement, scientific and technological innovation, and talent cultivation. The practice cases of the United States, Germany, Japan, and other countries have proved this point. In China, our industrial system is complete, the application scenario and demand is more complex, and more attention needs to be paid to aligning the top-level system with the green industry ecological construction.
Firstly, setting up a new standard for the green development of industrial Internet of Things (IIoT). In the field of industrial Internet, the industrial Internet platform is the core of industrial competition. General Electric (GE), Siemens, and other industrial giants have utilized their high-end equipment and products to establish industrial Internet platforms with various functions, such as industrial equipment connection, industrial big data analysis, and industrial application services, with the intention of gaining a competitive edge in the global IIoT market [
16]. At the same time, Microsoft, Cisco, Amazon, Intel, and other information and communication giants are also actively developing industrial Internet platforms by utilizing their strong position in software and hardware systems and solutions. For example, the U.S.-led Industrial Internet Consortium (IIC) has long been committed to building a globally unified industrial Internet technology standard and has been working with the International Organization for Standardization (ISO), the International Electrotechnical Commission (IEC), open-source organizations, and regional standards development departments, effectively accelerating the research and development process of relevant standards [
16]. Germany’s “Industry 4.0 Platform” has established a standardization agency (Labs Network Industrie 4.0), which is fully responsible for the research and development of standards in the field of the networked and intelligent manufacturing industry. And the IIC and LNI 4.0 have reached a cooperative relationship on “Standards and Interoperability”, with a view to working together on the development of standards and interoperability. It can be seen that the competition for standards, including those for green, healthy, and sustainable practices, is an important part of the market competition, which directly affects the industry’s technological system, industrial system, and so on. At present, the promotion of standardization in the IIoT is highly valued by countries around the world.
In addition to promoting the construction of industrial Internet platforms and the research and development of standards, manufacturing enterprises, and information and communication enterprises, industrial alliances and governments have also invested massive resources in establishing standardized industrial Internet business solutions, cultivating industrial Internet ecosystems, and strengthening industrial Internet application security. Therefore, China must urgently speed up the development of new domestic industrial Internet standards, including those related to green development, and actively align with the current international industrial Internet technical standards system, which has been the trend.
Secondly, building a cloud platform to accelerate green development. In recent years, China’s industrialization process has accelerated, the cost of labor and material costs continue to rise, and consumers pay more attention to the product process and quality. The methods of development for enterprises are gradually shifting from factor-driven, large-scale production to an innovation-driven approach, focusing on quality enhancement and green environmental protection. Therefore, manufacturing enterprises must actively embrace new changes, new technologies, and new trends and take advantage of the industrial Internet [
17].
It should be emphasized that building a perfect industrial Internet cloud platform requires government departments and industry associations to do a good job of coordinating and integrating their work and accelerating the research and development of strategic planning for the industrial interconnection of manufacturing enterprises and the related systems and norms [
18]. Among them, actively guiding manufacturing enterprises and equipment and component suppliers and outsourcing manufacturers, equipment manufacturers, platform suppliers, software developers, system integrators, and other parties to reach a unified industry standard, to establish a green cloud ecology to support the realization of sustainable development of the Industrial Internet, should be the most important.
Under the concept of green development, the cloud platform upholds the purpose of energy saving and environmental protection, high efficiency and safety to cultivate and develop intelligent production, network collaboration, service extension, personalized customization, and other emerging business forms and comprehensively promotes the transformation and upgrading of the manufacturing industry. Relevant enterprises should also actively cooperate with government departments and continue to promote their own cloud infrastructure and equipment’s intelligent transformation. They should enhance their ability to collect and apply industrial data, especially to strengthen the standardized use of data; to realize the barrier-free real-time flow of data in the enterprise equipment, workshops, departments, jobs, and partners; to improve their own competitiveness in the market at the same time; to reduce the demand for energy consumption; to enhance the added value of products; and to improve the competitiveness of China’s manufacturing industry of high-tech, low-consumption, and low-priced products. These efforts will support the contribution of energy to the transformation and upgrading of China’s manufacturing industry.
