I believe there is a new scheme being launched shortly, it is an attempt to get our sustainable energy figures up. If you invest in a turbine, PV panel or whatever - you can sell that energy back to the grid for 30p a unit. Bearing in mind you can buy power at 10p a unit, that is a significant amount of money. I know of several people who are investing in wind turbines for this sole purpose. Not sure how long this scheme will be in place for, but I know of several of our customers who are doing it.
