Egni Coop gathers lots of people together to invest collectively in renewable energy projects.
Once these renewables are installed, the electricity produced qualifies for a government subsidy called the Feed-in-Tariff. Additionally, Egni is paid for any excess power which is exported onto the National Grid, and the community buildings get free electricity.
The money raised then flows back into the Coop, and is used to pay interest to members, as well as to cover things like ongoing maintenance and development of future projects.
This is a model that has worked extensively in European countries such as Denmark and Germany. Indeed, there are more than fifty renewable energy coops in the UK. Some have raised hundreds of thousands of pounds, others millions. What joins them together is a grassroots effort to develop local renewable energy.
