@Viking_Hippie Sure there are alternatives but nothing can be put in place overnight and the capacity should be there before you should down fossil fuel plants. Also the only real reliable alternatives that can be scaled are nuclear fission and geo-thermal, and geo-thermal is only available in some geographical regions, although in the US you could build enough capacity in yellow-stone to supply the entire country, the same namby-pambys that are panic'ing over carbon dioxide don't want to risk diminishing the geysers. And most of them are also opposed to nukes.
