Europe faces a critical challenge in scaling renewable energy in agriculture, as isolated pilot projects have proven successful but widespread adoption remains limited.
Farms across the continent are already producing clean energy alongside food, using technologies such as agrivoltaics, farm-scale wind turbines, and circular biomass systems.
Despite the availability of these technologies, rollout is fragmented and often disconnected from the financial and policy frameworks in which farmers operate.
The EU-funded HarvRESt project has examined where renewable energy solutions are ready to scale and where enabling conditions are insufficient.
Solar energy is the most mature and investable option for agriculture, with agrivoltaic systems allowing energy generation alongside crop production.
Innovations such as Germany’s Next2Sun vertical bifacial panels and the Dutch H2arvester mobile solar units demonstrate high energy yields with minimal land use, enabling farmers to generate electricity and even produce hydrogen for long-term storage.
Wind energy is technically feasible but underdeveloped in agricultural settings due to the lack of farmer-friendly business models.
Dutch company Ecoways is addressing this gap by deploying compact wind turbines and hybrid systems combining solar, wind, and storage to provide reliable, self-sufficient energy for farms.
Biomass and biogas technologies offer circular solutions, particularly for small and medium-sized farms, turning animal manure and crop residues into electricity, heat, and value-added products.
Italian start-up MicroBiogasItalia and Ireland’s Comhar Bia network are examples of distributed, cooperative models that make biomass systems economically viable while enhancing rural economies.
Scaling renewable energy in agriculture depends not only on technology but also on supportive policies, access to finance, and long-term market stability.
HarvRESt is bridging this gap by testing renewable solutions on farms, developing decision-support tools, and fostering multi-actor collaboration between researchers, policymakers, and investors.
The initiative highlights that Europe’s challenge is systemic rather than technological, emphasizing the need for integrated frameworks to make renewable energy deployment practical, attractive, and economically sustainable for farmers.
