I heard that there is a new possibility in the USA from this year to use crowdsourcing to raise equity without the normal regulatory process. However, it would take a lot of people to raise the amounts of money needed to make a difference. Say you want to raise 50 million euro for a wind farm. It's drop in the ocean for an investment fund, but you'd need 50,000 people to commit 1,000 euro... 50,000 is a hell of a lot of people, and not very many people can speculate with even 1,000 euro! As wealth gets more and more concentrated, crowdsourced finance becomes less probable, I think.

I'd like to see fossil fuel subsidies go to renewables and efficiency - so the conventional energy companies are left to crowdfund their new projects!

Ecotoo, crowdfunding for renewable electricity is very well possible. In the Netherlands we have a company called "windcentrale" (https://www.windcentrale.nl/). Their FAQ #7 explains their model but since it is all in Dutch let me give you a hand: The Windcentrale divides a wind mill over several 1000 pieces. Every "windshare" has an expected production of 500 kWh per year. Participants can buy 1 or more shares to a maximum of 85% of their historic consumption. The generated electricity will be divided amongst the shareholders during the mills life-time and delivered at their homes. This gives participants price-stability and guaranteed 100% sustainable energy. Try an internet translation on their FAQ for more information. They explain very nicely how they solve construction lead-times etc.
