This is also something I have against heat pumps when compared to a gas furnace for heating. The gas furnace is 80-90% thermally efficient. That is the amount of energy in the fuel that makes it into the space or water being heated, with the remainder ending up in the exhaust gases and vented outside as waste.

The heat pump is touted as being vastly better because it is 300% efficient, but ignores that electricity generation is typically 30% and at best 60% efficient. At 30% efficiency generating efficiency the heat pump has to be 266% efficient to match that 80% "inefficient" gas heater when you don't ignore generating efficiencies.

Photovoltaic solar is about 10-20% efficient, while wind and hydro are 80%+ efficient because they don't count the thermal cycle that creates wind and rain, but it's still there, safely out of sight.

For comparison, a typical coefficient of performance for a heat pump looks to be 2-3 (200-300%).
