Gets just a little tricky on one aspect;

Lots of oil sites, oil refinery plants, (heck, even landfills) just 'flare' excess Natural gas today.

Biggest reason for that, is, they don't have the infrastructure to store that excess safely (at least around here, a lot of the landfill trucks are NG powered as a way to lower their fuel costs and lower flaring, but storing too much NG in one place makes for a fun terrorism target.) Natural gas is actually -way- worse for global warming than CO2, thus the flaring process.

Not saying that's a good thing. It would be better if companies saw the growing energy demand and figured out how to economically put power generation in place, back when such projects would have been cheaper to build. Alas the cost/benefit for that has usually been on the wrong side, to the detriment of us all.
