An Oklahoma power company called
AEP-
PSO, is helping customers go green. Customers can choose to have their electricity come from wind power instead of coal. For just $2.85/100 kilowatts, Oklahomans can help save the planet. Wind power does not emit carbon dioxide like burning coal does. If everyone switched to renewable energy, it would save millions of pounds of co2 from being released into the environment.
