This website has an incredible amount of information on it. It is a really great primer on Wind Power. The technology, environment, public policy, and lots more. Very easy to read too!
The Danish have got it figured out. Over 20% of their electricity comes from wind power. Each megawatt produced by wind power is money that does not need to be sent abroad to purchase fossil fuels. And, about 90% of the wind turbines they produce, are exported. Their currency is definitely not going to depreciate because of their wind industry, but appreciate.
