Rock Port, MO - As energy costs go up, we're all looking for ways to save money. Just down I-29, an entire town takes action and risks on a power supply right outside their back door. Someday, it may be a money-saver.
 
Look down the road on this Rock Port farm, you'll see the spinning shadows over the corn fields. Look up and see the giant blades that power the town.
 
"It's the way to go with electricity as far as I can see," Steve Scamman says.
 
Rock Port flipped the switch to wind energy three months ago. It's the first U.S. City totally powered by wind. The immediate benefit - it's clean and good for the environment.
 
"Those turbines produce electricity without any emissions, without any other fuel source other than the wind. They produce a lot of power," Wind Capital Group's Eric Chamberlain says.
 
Wind power runs the traffic signals, the clock at the bank and keeps the lights on at the hair salon.
 
Chamberlain is Rock Port's wind czar. "I was born and raised here and began to think it's windy a lot of the time," he says.
 
Already the wind is strong enough to meet the demand. It's even possible the wind will blow hard enough to produce more power than Rock Port needs and the town will sell the surplus.
 
You might think the windy plains of Nebraska would be a good power supply. OPPD tells us wind isn't always reliable, the equipment is expensive and it costs a lot to get power from those turbines to your house. There are only a few places in the state windy enough to make it worthwhile. Right now, OPPD buys wind energy from NPPD and wants to buy more.
