Assuming the efficiency gains are real, increasing the max COP ("efficiency") of heat pumps beyond their already astounding levels of near 5 (500%) would be a game changer for heating and cooling.
Even at quite cold temperatures (sub freezing), the latest heat pumps achieve a COP of 2.5 (250%), a level at which they beat the efficiency of gas furnaces even when powered by 40% efficient natural gas generated electricity.

- danans 5y agoTechnologyConnections is the best ;) I did indeed borrow his numbers. But also, I installed a whole house heat pump about a year ago so also have real life experience with them, and with my electricity plan, it's even better from a CO2 perspective since it is 100% wind/solar/hydro based.
