Wind energy is currently supplying enough electricity annually in the United States to power more than 4.5 million homes. While that sounds like a lot, less than 1% of the nation’s electricity is currently supplied by wind power, according to the American Wind Energy Association. In Europe, Denmark gets more than 20% of its power from wind. In 2007, Germany received about 7% of its power from wind.
In the United States, the winds in North Dakota alone could supply about one-third of the nation’s electricity, but there are adequate winds for commercial power production at various sites in 46 states.
The other wind energy fund expected sometime soon is the PowerShares Global Wind Energy Portfolio.
Seems like wind power has lots of potential for growth in this country.
