Cumbria-based Energy4All enables anyone to invest in renewable energy, provided that they have at least £250. It does this by helping communities to set up co-operatives that own wind farm capacity, and by carrying out regulated offers to sell the shares. By guiding through the many financial, legal and technical hurdles, it takes the pain out of the process of setting up a co-operative. Energy4All now manages eight co-operatives with 7,690 members, who collectively own the equivalent of over 20 MW of capacity in UK wind farms. In 2011 this generated over 45 GWh of electricity, saving 19,500 tonnes of CO2 emissions.
