Examine the facts, then decide for yourself.
Denmark is the world’s most wind-intensive nation with more than 6,000 turbines generating 19% of its electricity. But consider this:

Not one fossil fuel power plant has been closed
50% more coal-generated electricity is needed to cover wind’s failings
Pollution and carbon dioxide emissions rose 36% in 2006 alone
Danish electricity costs are the highest in Europe

So what are the Danes saying about wind power now?

“Windmills are a mistake and economically make no sense.” – Neils Gram, Danish Federation of Industries
“Wind turbines do not reduce carbon dioxide emissions.” – …

The wind farm industry has been forced to admit that the environmental benefit of wind power in reducing carbon emissions is only half as big as it had previously claimed.
The British Wind Energy Association (BWEA) has agreed to scale down its calculation for the amount of harmful carbon dioxide emission that can be eliminated by using wind turbines to generate electricity instead of burning fossil fuels such as coal or gas.
