> Our biggest environmental footprints as individuals are heating and cooling. Having an electric car is nothing compared to it. Isn't Tesla aiming to electrify everything and then use clean energy as the source of the electricity? At the moment running heating or cooling should be clean as long as the energy is coming from a renewable source, right? > Take one intercontinental flight and again, having a fossil fuel car for a year does not exceed the emissions of that flight. For the entire flight, right? I would be curious how much driving one seat on a flight equates to. I presume flying is at least better than driving on a per-mile basis?

Adjusted for your own seat, assuming a full plane. You can read about the calculation in the linked book. http://www.withouthotair.com/c5/page_35.shtml http://www.withouthotair.com/c5/page_35.shtml

You can’t compare the two so cleanly as to conclude with a simple this is better than that. There’s different effects of different types of pollutions at different altitudes, some unknown. Brake dust, the knock on effects of needing more road due to more miles driven, the infrastructure required to operate an airport, etc.
