The European Union aims to cut greenhouse gas emissions by at least 55% in 2030 compared to 1990 levels, and to become the first carbon-neutral economy by 2050. This ambitious goal requires a radical increase in the production of green energy within a relatively short timeframe. The untapped potential of rural areas in the union offers a way forward.Rural areas could produce more energy than we needRural areas cover more than 80% of the EU’s territory and are host to around 30% of its population. Our work at the European Commission’s Joint Research Centre (JRC) shows that rural territories already generate the largest share of green electricity (72%) from the three most prominent renewable technologies: solar photovoltaic, onshore wind and hydropower. The remaining share of renewable energy is produced in towns and suburbs (22%) and cities (6%). Germany, Spain, France, Italy and Sweden are the top five renewable energy producers in the union, accounting for 68% of its total production from solar, onshore wind and hydropower installations.But there is more. According to our analyses, rural areas also possess the highest untapped potential of renewable energy production–nearly 80%. Theoretically, they could produce enough to meet the total energy demand of the EU. We estimate that the total potential of solar, onshore wind and hydropower energy production in rural areas nears 12,500 terawatt hours per year. That’s more than five times the amount of electricity the union consumed in 2023, and it surpasses total energy consumption (which includes sources such as gas, oil and coal) for that year, too.Technologies that suit the landAll this energy could be produced in rural areas without disrupting existing agricultural systems, landscapes and natural resources. Rural areas could produce up to 60 times more solar energy than what they currently deliver, quadruple their output from wind, and boost hydropower production by 25%. Spain, Romania, France, Portugal and Italy are the five EU countries with the highest combined (solar, wind and hydropower) untapped potential: together, they account for 67% of the EU’s potential, with contributions from rural areas ranging from 92% in France to 49% in Italy.Overall, solar panels installed on the ground can make the biggest contribution to green energy production in the EU. However, rural areas across the union are highly diverse, so choosing the right technology would depend on local characteristics. Mountainous areas with abundant water resources are a good fit for hydropower production, while rural municipalities with large areas of suitable land lend themselves to solar or wind energy, depending on sun irradiation and wind speed. In rural areas where wind and land are insufficient, rooftop photovoltaic systems are a good option.Boosting clean energy production can be a win-winRural areas are key to producing more renewable energy, as almost 80% of suitable, available land is located there. In addition, some of these areas are facing demographic and economic decline and are already the target of measures aimed at making them stronger, resilient and prosperous–as part of the EU’s long-term vision for rural areas. In this context, ensuring that these areas benefit economically from hosting more renewable energy projects makes them even more enticing. It also aligns with political considerations, as energy independence is a key part of the EU’s goal of strategic autonomy. À lire aussi : Could the EU's Green Deal provide security benefits? Addressing local concerns and fostering acceptanceWhile the potential offered by renewables is unquestionable, their production sites can face resistance from communities concerned about impacts on the local economy and quality of life. Seeing land used to produce energy with little local employment and seemingly for the benefit of large companies can also lead to resistance. Other concerns include competition for land use in areas where income is tied to other industries (such as agriculture or tourism), and the potential environmental impact of solar panels and wind or hydropower plants on rustic landscapes. With these concerns in mind, we identified portions of land suitable to host renewable energy plants that comprise roughly 3.4% of the EU’s surface. We excluded protected nature sites and biodiversity areas, forests and water bodies. We used strict limits on the use of agricultural land for energy production by only considering land that has been abandoned or has a very low productivity. Finally, we created buffer zones around infrastructure and settlements to minimise disturbance and safeguard natural beauty and cultural heritage.Engaging local communities to find solutionsIn our report, several case studies show the successful implementation of renewable energy projects in rural areas, driven by community engagement, collaboration and innovative financing models. From the first community-owned turbine in southern Europe in Catalonia, Spain, to a commercial energy company giving part of its profits to a local cause chosen with an energy community in the northern Netherlands, these cases highlight the potential for such projects to contribute to energy security, produce economic and social benefits and promote environmental sustainability.These case studies show that active involvement of local communities from the early stages of renewable energy projects can foster acceptance. Citizens who are actively engaged or even share ownership in small- or medium-scale projects become more supportive. Beyond seeing profits stay local, engaged communities can mitigate negative effects of production by, for instance, choosing where to locate new energy plants.Our report also offers an overview of renewable energy communities’ role in ensuring a sustainable energy transition in which rural areas are not left behind. The number of renewable energy communities in the EU is rising and, although an exact count is unavailable, it is estimated that there were over 4,000 of them, with some 900,000 members, in 2023. These communities are mainly concentrated in northwest Europe, and a high proportion are rural. Beyond energy communities, place-based approaches, where local populations and administrations are engaged from the early stages and see clear benefits, can make an important contribution to our sustainable transition.Lewis Dijkstra ne travaille pas, ne conseille pas, ne possède pas de parts, ne reçoit pas de fonds d'une organisation qui pourrait tirer profit de cet article, et n'a déclaré aucune autre affiliation que son organisme de recherche.
