And that’s just looking at the most basic swap out. The whole point of the energy transition is to also make everything better. Continent wide energy grids need to happen ie. Wind in Norway, solar in Morocco and a grid between etc. local generation by solar or wind also has a huge part to play. Geothermal is getting much better with lower temperature or harder to reach heat sources too, see Eden Project in Cornwall.

If you haven’t already have a watch of the Everything Electric videos on YouTube for good views on how wide this whole thing is going to have to be.
