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, because they move heat instead of creating it by burning stuff. This lets them be more than 100% efficient. You can expect something like 300% efficiency averaged over a year for air-sourced heat pumps in the US which are sized correctly for the house they're in. This makes them a net benefit, even on the current electrical grid.
People also often choose to add insulation when installing heat pumps, as this has the benefit of lowering overall system cost, which makes the situation even better.
