Since earliest recorded history, windpower has been used to move ships,grind grain, and pump water. Today, windpower is also being used to provideelectricity to homes, schools, busi-nesses, and entire communities. Morethan half the United States have windresources that could support the devel-opment of utility-scale wind powerplants.

We have enough wind in Colorado togenerate 288 billion kilowatt-hours (kWh)of electricity annually. That’s enough toserve double the entire state’s popula-tion. Construction on Colorado’s firstwind farm, Public Service Company’sPonnequin wind farm located near theColorado-Wyoming border, began inJanuary 1997. The first wind turbine wasinstalled in January 1998 and begangenerating electricity in April 1998.Today, Ponnequin boasts 29 turbinesthat generate 20 megawatts (MW) ofelectricity.

Colorado utilities also purchase windpower for their customers from windfarms in Wyoming. Public ServiceCompany purchases wind power fromthe Foote Creek Rim Wind Farm nearArlington, Wyoming. In addition, four tur-bines recently installed at Medicine Bowby the Platte River Valley Authority willserve green-pricing customers andrenewable energy programs in Aspen,Fort Collins, Longmont, Loveland, andEstes Park.

What is Green Pricing?In Colorado, customers can arrange to purchase a certain amount of windpower (actual energy in kWh) per month,for which they commonly pay a smallpremium to completely or partly offsetany higher cost of renewable powersources. The policy of transferring theslightly higher costs for "green power" to customers is called "green pricing."Green power is power produced byrenewable or environmentally friendlyenergy sources, as distinct from powerproduced by fossil fuel, nuclear, andother types of generators.

How Do I Sign Up?Residential and commercial customerscan join wind power programs acrossthe state by signing up through theirlocal utilities to buy wind energy in 100-kWh blocks on a monthly basis for$2.50-$3.00 per month above existingresidential rates. Since wind power pro-grams were introduced in Colorado in1996, more than 16,000 customers havesigned up for wind power for their homesand businesses.

You can sign up for wind power throughyour local utility or online. To sign up forgreen power and calculate the environ-mental benefits of your purchases, visithttp://www.cogreenpower.org/

What is the installed wind energy capacity in the United States?

By 2000 the total U.S.installed wind energycapacity is 2,650 MW.(See http://www.awea.org/faq/instcap.html) That’senough electricity to meetthe needs of 600,000 to800,000 typical U.S.homes.
