I’m surprised it hasn’t been increasing faster. The US is in the midst of drive to replace heating systems of all kinds with more efficient heat pumps, with massive effort behind it, including restrictions on other kinds of heat, significant tax returns for upgrades of existing systems, etc… and they are lumping heat pumps into the figure.
> 88% of U.S. households use air conditioning (AC). Two-thirds of U.S. households use central AC or a central heat pump as their main AC equipment.
- bombcar 4y agoThe cost of central air has been dropping (it was something like $3k add-on to a furnace replacement) and so rarely do you install or replace a furnace without A/C, and once you have central air, you just set it and forget it. Even a fancy thermostat is going to use more energy than a loud window unit that you turn off whenever possible.
- rwcarlsen 4y agoIf you use a heat pump in winter you do actually make outside colder. So there is that analog.
- alach11 4y agoI think technically you still make the outside warmer, once you account for heat leaking from the house and waste heat from the heat pump.
