Rock Port, MO - 100% of Energy from Wind

Vehicles in this northwest Missouri farm community are likely to be pickup trucks, and "green" is the color of a John Deere tractor.
But when it comes to alternative energy, little Rock Port - population about 1,400 - is a pioneer: it's the site of a wind farm that's projected to generate more electricity than the town uses in a year.

Four 250-foot wind turbines on the town's western bluffs are the source of Rock Port's alt-energy designation. The massive turbines linked to the city-owned utility were installed early this year by St. Louis-based Wind Capital Group, with financing from Deere & Co., the world's biggest manufacturer of farm equipment.

"We are always going to be agriculture-based. We are always going to be rural," said Eric Chamberlain, project manager for the Loess Hills Wind Farm. "But there are things we can do certainly, and we're doing it.

"I mean, when you remove your carbon footprint for the entire town for electricity production, that's a pretty big deal."

The wind turbines in Rock Port are estimated to generate about 16 million kilowatt hours of energy a year, or about 3 million more than what Rock Port typically uses. That's thanks to northwest Missouri gusts that put the region, where Wind Capital has three other, larger wind farms, among the windiest parts of Missouri, which ranks 20th in the nation in terms of wind potential.

Wind energy has been gaining momentum in the U.S., growing by 45 percent last year and now providing about 1 percent of the nation's energy, according to AWEA. A study from the Energy Department and the industry found that wind could generate 20 percent of the nation's electricity by 2030.

But that doesn't mean Rock Port is off the electrical grid and getting all its electricity from wind.

In May, for example, on days the turbines didn't spin, the town pulled its energy from the rural electric cooperative. But for the overall month, the turbines provided 107 percent of the town's needs, Chamberlain said.

When the turbines churn out more than Rock Port needs, the remaining energy is sold by Deere, which owns the turbines, back to the Missouri Public Energy Pool. The pool then distributes it to its other 31 co-op members...

Other cities like Hull, Mass., and Aspen, Colo., were earlier on the wind curve, but Rock Port's projected estimate of its turbines generating more wind than the town needs in a year appears to be a first for the U.S. Hull has been producing about 12 percent of its energy needs with two city-owned wind turbines since 2006.

And Aspen gets 75 percent of its energy from renewables, said Sally Spaulding, Aspen's director of community relations. Aspen also won the Department of Energy's Wind Power Pioneer Award for 2008 because it buys three times more wind power than any other public utility in the country on a per capita basis...
