Stupid children. Don't they understand personal consumption is irrelevant and "carbon footprints" are industry propaganda? If they actually wanted to make a difference, they should have spent more time shitposting about the 100 corporations that produce 70% of fossil fuel emissions.
Those numbers you cite are based on "scope 3" emissions, which is to say, the emissions that are produced when the fossil fuels those companies extracted are ultimately burned.
Individual consumption of fossil fuels also needs to end. This is part of that.
They've been used in warmer parts of the country for quite a while, but ones which remained highly efficient below freezing only became commercially available in the US a few years ago.
Depends. There are ones like that still sold. There are ones which don't switch to resistive heat until -10°F. Probably even colder too, but not sold where I live
