If it were that simple we would have unlimited free energy by simply using heat pumps to power steam turbines. I don't think heat pumps can generate very high

I don't think heat pumps can generate very high temperatures efficiently.
Resistive heating is 100% efficient by definition. There is almost no energy lost. the only loss of energy is light generated.
- maxerickson 11y agoThe thermal losses at the power plant are kind of a bummer. (My vague understanding is that heat pumps are not cost competitive with natural gas for winter heating)
- ryanstanton 11y agoResistive heating is 100% efficient, yes, but the electricity required to power the element is rarely above 40% efficient for most combustion powered sources (combustion turbines, combined cycle, etc.).
