CER (community energy river) offers services to energy cooperatives, focusing on energy-saving and clean energy production. Also, CER has designed a fintech platform that groups efficiently individuals and companies into energy cooperatives and facilitates them to buy, produce and sell their own renewable energy on a local level. Our vision is a future of Greener & Sustainable energy. The problem is to involve citizens in a clean energy transition and to familiarize them with new technologies. This involvement is important for economic but also technical reasons because local energy production reduces energy losses. Until now there is a lack of knowledge about the energy needs from demand-side which makes the system inefficient. Energy cooperatives offer a great solution: 1. To reduce energy cost 2. To help the energy market grow by having a balance between offer and demand and illustrating successful use cases to inspire citizens 3. To support local communities by boosting the local economy through projects of RES (wind, sun, and waves) CER Accelerates the creation of Energy Cooperatives, Digitalizes their management, Facilitates their investments and Develops their Market opportunities.
