Now Obama is allowing an increase in coal burning that will have the USA putting out 50% more CO2 in 15 years, while they spend a couple billion on solar and push themselves as green.
Remodeling existing homes with Earthship style mass walls and sun rooms for heat and growing food, attaching straw bales to super insulate the rest of the house, putting solar panels on the roof, and hybrid/electric cars in the garage are what is needed by the many millions--like all 80 million homes in the USA. No more coal!!! Phase out the coal plants here, immediately!!
