To the interest of probably very few, the (private) utility company that 
serves my area is Mid-American energy, a division of Berkshire Hathaway.
When I moved in here my electricity cost was approximately halved from 
what I was paying to Nebraska Public Power, a quasi-government entity.

Anyhow, Mid-American has invested heavily in wind power, their web  site 
probably has the gory statistics on it.  About thirty miles south of 
where I'm sitting is a wind farm that covers several square miles of land 
area, and they're adding more turbines as I type this.  Their goal is to 
generate most of their electricity using wind power.

When I was a youngster (a VERY long time ago) I lived in California 
(NORTHERN California).  Back in the last half of the 1950s somebody 
noticed that the hot air over California's Central Valley went up, and 
caused a significant amount of wind over the hills east of San Francisco 
Bay.  So they put up a couple of windmills to harvest electricity from 
that wind in Altamont Pass, which was known for its consistent high 
winds.  That worked very well, and over the next decade or two dozens of 
wind generators sprang up along that range of hills.

Then the whacko environmentalists got involved, and sued the h*ll out of 
anybody that had built a wind generator there, not to mention the usual 
rioting at the company's headquarters and executive's homes.  So most if 
not all of those windmills are gone, now, and California suffers from a 
significant power shortage (DUH!).
