Combined Heat&Power. The rustbelt and the oil, coal and gas states have vast untapped potential for combined heat & power, as I’ve covered before: 7 Quadrillion BTUs of Free Energy Available. It’s free. In fact many industries could sell electricity from the byproduct they make as they make other things. Heat. This is a great opportunity for cement makers and paper-mills to make a side income. Any industrial process that creates heat could also generate electricity on the side.
The DOE is investigating using a variation of CH&P for getting electricity from the hot water they create as a byproduct of oil drilling – so it is sort of a hybrid between “artificial” geothermal power and CH&P:
