well I am in the rabidly alternative energy northeast. How does gore do it in coal nearby tennesee? seriously I have an option for about 4 or 5 green energy sources. but since I make about 4 kw an hour with solar, it doesnt mean much to me and no I dont think co2 is the cause for global warming, and i didnt put up solar because i am a member of the green party. I just liked it
