One of the most effective ways to make a lot of renewable energy with just a little patch of land is to use a large wind turbine. Solar too is always better when there is a lot of it. However large scale wind and solar don’t come cheap. One way around the high cost of these projects would be to get together with a bunch of your friends and neighbors and pool your resources.
This would allow you to buy a very large wind turbine, or set up a field of solar for your neighborhood, use the energy from it and sell the rest. The offset of not having an electric bill combined with the revenue sharing would be used to pay back your part of the investment. You would in essence be your own little neighborhood power company.
There is only one problem…
