Generation and distribution are legitimate concerns. But it's rubber-meet-road at the point of use. If geodesic dome houses had become the norm in the 1970s the housing stock would be largely converted. The total requirement would be somewhat less. 50%? 10%?
Just having a wind powered ventilation system is a start. Space and water heating. An electrical microgrid if in a Democrat-run state.
