Coal and oil - supplies are finite, takes a lot of effort to "gather", and finishes up filling the atmosphere with CO2, carbon etc etc
Solar - clean but very limited.
Nuclear - no CO2, but a helluva problem with the waste.
Why is
nobody pushing Geo-thermal power generation ?
Drill the hole; push water down it, and get super-heated steam back up the pipe, and the only by-product is pure water !!! Unlimited energy and no crap for the atmosphere.
Oh how selfish of me. Just think how many coal and oil industry workers that would be put out of work !!!
