doesn't matter. gas pipes leak, and shall appliances aren't efficient, so even if the grid was 100% fossil fuel (which it's not), it still would be more efficient to use electric in the home.

Efficiency wise you may be wrong. Carrying electricity is not efficient (you lose energy with distance) while gas (as long as leaks are limited) is a more efficient store of energy from start to end.
