America Needs To Install A Lot More Heat Pumps
(www.distilled.earth)
Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.
As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades:
How much each change to the atmosphere has warmed the world:
Recommended actions to cut greenhouse gas emissions in the near future:
Anti-science, inactivism, and unsupported conspiracy theories are not ok here.
Yes, over 100% efficiency is exactly what I claimed. In winter, you'll get more BTUs of heat output from a heat pump than you had put in as BTUs of electricity input -- because instead of converting the electricity to heat, it's using the electricity to pull heat from the outside and put it in your house. Hence, it's a more energy-efficient way to do things than the laws of physics would allow for a device that directly converted electricity to heat. That's what it means to be a reversible air conditioner, yes.
IDK why me saying that is some kind of controversial statement -- it's simply a factual description of the product. There are scenarios and real-world constraints which may mean it's more or less sensible to install one, but over 100% efficiency is, exactly, the selling point of a heat pump.
