Wind Power Introduction
Like hydropower, wind power
has been used for centuries, to lift water, propel boats, grind
grain. It is an attractive and non-polluting source for
electricity. It has only been since the mid 1980s, however, that
wind power has contributed appreciably to our supply of
electricity. The largest generating capacity in the world at
present is in Germany, although Denmark is targeting wind as the
source of half of its electricity in the near future, if public
opposition to their visual intrusion can be overcome.
Some of the largest "wind
farms" in the world area in California. One, that in San
Gorgonio Pass, is about 100 miles west of Arizona, near Palm
Springs, California, where about 4000 wind turbines convert wind
power into electricity power. The other major installations in the
US are similarly located in passes where the winds are
concentrated. Without such concentration, the density of wind
power is usually too low to generate electricity commercially.
Like many other states,
Arizona has long used wind power to pump water on ranches.
Nowadays, this is not a major use in Arizona. Indeed, few sites in
Arizona are consistently windy enough for commercial development.
Only northern Arizona (for example, near Winslow) might be
commercially attractive. As yet, no projects of this sort are yet
in place.

Large
Wind/Solar Electric Array SE of Tucson?
The Willcox Playa wind solar
electric array is a project that needs to be moved forward for it is
a totally positive project. It pushes the envelope of education in
both wind and solar electric generation. Read more about the
proposal here...
Wind energy becomes cheaper than conventional
energy (AP, 10/17/2005)
The Denver Post - Customers of
Xcel Energy's Windsource wind energy program soon will have more
to brag about than their environmental ethic. Namely, lower
bills. Click

APS Wind Integration Study
(September 2007)
The final report of the APS Wind Integration Cost Impact Study was produced by Northern Arizona University (NAU), with contributions from EnerNex Corporation, 3TIER, and Arizona Public Service Company (APS). The report is a result of an eight month study to characterize the impacts and costs due to the variability and uncertainty of wind energy associated with integrating wind energy into APS’ utility resources and practices.
