The ultimate sustainable living is a commie-block in a reasonable small, walkable city with a good public transport and services mixed with residential areas. If you do that - it doesn't matter what the source of heating, energy etc. is, and what kind of a car (if any) you drive. Even if it's all coal and fossil-fuel powered - you are order of magnitude more sustainable than people living in suburbs with solar panels, heat pumps and Teslas simply because you waste so much less energy on building and transporting stuff to make living there possible.
