Saladbar,
Could you explain the solar power? Here in NY, if you install solar panels on your roof, the kwh supplied by the panels gets DEDUCTED from your bill. The purpose of the panels is that you store enough energy so that your meter actually begins to spin backwards. Why would he billed for having it?? Are the laws different?
Thanks for the information.
He uses a program called GREEN POWER SWITCH available in Tennessee (not sure what other states). Using this you pay more because although sunlight and wind are FREE the "technology for capturing their energy is still more expensive than traditional power generation methods". By chosing to pay more, if you have such means (as Gore does) then you "help advance the technology and increase the amount of electricity generated from cleaner sources" and the money goes into more research.
So that is why it costs MORE.
