This is going to be important because as our climate changes and governments will finally start making the difficult (but necessary) decision to cut carbon emissions, the grunt of the work with dealing with the consequences will fall on regular people. Knowing how to heat/cool your environment is already a survival skill, and that will become even more necessary in the near future.
Cars are terrible, they’re bad for the environment, and they’re bad for the individuals who own them (financially speaking). If people switched to public transport and ebikes the whole world would be better off.
