Especially if you're in Pennsylvania, you've probably heard a lot about electric utility deregulation. So far, there are three electric suppliers in Pennsylvania marketing electricity under the 'Green-e' label. If you've been paying any attention, you've probably heard a lot from the first two by now. The third is a non-profit, so you won't be hearing much from them. The rest of the electricity can still include nuclear, coal or other dirty power sources, but must not be any dirtier than the normal system power already available on the power grid.
Wind is the best energy source there is.
According to Department of Energy research, wind alone has the capacity to power this whole country's energy needs many times over. There is no wind capacity installed in Pennsylvania. Moreover, there are no serious proposals to install wind projects in Pennsylvania right now. Green Mountain Energy Resources, while advertising widely with pictures of windmills, has made only a lukewarm commitment to build windmills in Pennsylvania. Initially, they were talking as if they'd build a windmill for each 3000 customers that are enrolled in a specific program of theirs.
