A lot of energy is used for heating, heating water is more efficient with fossil fuel than with electricity - because for electricity you have transmission loss.

Fossil fuels have transmission losses too. You just don't see them.
40% of all global shipping is used for fossil fuels. [1]
10% of the energy in a barrel of crude oil is used to refine it. [2]
I'm not even counting the energy cost of crude oil extraction, pipeline leaks, hauling gasoline, diesel and LPG to its final destination, or the million other places where energy is lost.

That used to be the case, but with the efficient heat pumps that have come out in the last few years, that is no longer true. Since you’re using electricity to move heat rather than produce it, it’s two to three times more efficient than burning fossil fuels for heating.
