Google Energy fuels its Oklahoma plant with energy from wind power in Oklahoma: http://www.rechargenews.com/energy/wind/article291445.ece
Next Era is the largest generator of wind and solar energy in the country and it has the capacity to produce over 8,500 megawatts from green renewable sources. That is enough green energy to to power 2,465,000 homes on a regular basis (assuming a constant energy output). That is more than one-third of all homes in the San Francisco Bay area!
Current estimates put the total percentage of renewable energy consumed in the U.S. at only ~seven percent. Energy from petroleum and coal add up to roughly 65 percent. This means that we need a nearly eightfold increase in renewable energy sources to make them the dominant form of energy in the U.S. so get out your bikes and solar panels and rock on!
