Special Issue Information

Dear Colleagues,

Energy-sharing mechanisms and renewable energy communities (RECs) have changed the paradigm of energy production, distribution, and consumption. The increasing number of decentralized renewable energy systems allows communities to reduce their dependence on traditional grid systems and share surplus energy using digital platforms and smart grids. This is based on real-time consumption, enabling the balancing of energy supply and demand within communities.

From a technological point of view, the success of RECs depends on advancements in energy storage systems, blockchain for peer-to-peer trading, and evolving energy management systems.

Despite the huge impacts, many challenges remain: regulatory barriers and the need for standardized frameworks across regions, issues related to interoperability between different technologies, high investment costs, and the need to ensure equitable access to benefits. 

A fundamental aspect to ensure the success of these new energy paradigms encompasses community engagement, as well as the formation and information of populations regarding personal and social opportunities, such as increased energy independence, lower carbon emissions, and economic benefits for participating households. Energy-sharing mechanisms also support the transition to more resilient and sustainable energy systems, aligned with the climate action goals and the democratization of energy.

Energy communities led by local citizens are vital for achieving the European energy transition goals. This study examines the design of a regional energy community in a rural area of Spain, aiming to address the pressing issue of rural depopulation. Seven villages were selected based on criteria such as size, energy demand, population, and proximity to infrastructure. Three energy valorization scenarios, generating eight subscenarios, were analyzed: (1) self-consumption, including direct sale (1A), net billing (1B), and selling to other consumers (1C); (2) battery storage, including storing for self-consumption (2A), battery-to-grid (2B), and electric vehicle recharging points (2C); and (3) advanced options such as hydrogen refueling stations (3A) and hydrogen-based fertilizer production (3B). The findings underscore that designing rural energy communities with a focus on social impact—especially in relation to depopulation—requires an innovative approach to both their design and operation. Although none of the scenarios alone can fully reverse depopulation trends or drive systemic change, they can significantly mitigate the issue if social impact is embedded as a core principle. For rural energy communities to effectively tackle depopulation, strategies such as acting as an energy retailer or aggregating individual villages into a single, unified energy community structure are crucial. These approaches align with the primary objective of revitalizing rural communities through the energy transition. Full article
