I don't care if renewable electricity is more expensive - we should be using as much of it as we can for the planet's sake. He who wants to eat cheap may often eat dirty.
A rather cavalier attitude as the cost of energy has a lot to do with people’s standard of living, especially in developing countries.
Natural gas is hardly a “dirty” fuel, and modern coal plant stack emissions are pretty innocuous if the mercury is scrubbed.
Just where in the hell do you think all that carbon came from in the first place ?
