A while ago I switched to Good Energy for electricity. They state on their website that 100% of the power you use comes from renewable energy, although it can take up to a year for this to work through:
“Good Energy customers will always get a supply of electricity even if the wind stops blowing. We promise to buy the same amount of renewable electricity over 12 months as our customers need, so at some points during that 12 month period Good Energy will be purchasing too much renewable electricity, and at some points it will not have sufficient renewable electricity. However, over the 12 months the supply and demand of renewable electricity will match.”
In addition, they now offer the option of selling power back to them. However, the price you pay (about 11p/unit) is quite a bit higher than the sell price of about 4p/unit. If I ever did get a wind turbine installed, this would help to off-set some of the costs. Not only would I save just by being able to generate my own power, but because the wind doesn’t always stop when I’m not using power the excess can be sold rather than wasted.

Good Energy sound great in principle but their customer service can be dire – phones never answered, calls back days later when you’re out, emails ignored. I’ve never come across anything like it. Watch out if you have something that needs sorting!
