Have you seen this? The Windsave system is a personal wind-powered dynamo for houses that allows you to generate a bit of your own electricity—up to 33% of your yearly usage (based on the average UK household consumption and average UK wind speed).

They aren’t cheap at around £1,000, but with potential government subsidy, the company estimate that you’ll make up the purchase price within 5 years (based on the same stats as above).

I first read about this on Gizmodo, a great gadget site.
