Given an on-the-grid, non-solar house, is it more energy efficient to charge your phone in your house or in your car? If there would be a difference for gas-powered and electric vehicles, please explain that as well.

i’d say house. it takes the same amount of power to charge your phone regardless. if your car is running, obviously you are just wasting energy while your phone charges. if it isn’t running, youre just trading the energy in your car battery to your phone. replacing that energy eventually requires starting your car which in this scenario is the least efficient thing. or if you have an EV hooking it up to the grid anyway.
