Next thing you know is that we'll be importing billions of plastic bottles filled with water from France, Spain and Italy because we are so desperately short of the stuff.
These things drive me insane.

Council houses, or I suppose housing association houses th these days. How much money is it going to cost to upgrade all of these properties with a heat pump?
In the US roughly 237 TWH of coal is burned per month to produce 76 TWH of electricity. Similarly roughly 292 TWH of gas is burned per month to produce 129 TWH of electricity. Renewables only need to replace 205 TWH of electricity to displace 529 TWH of fossil fuels on your graph.
The remaining coal and gas is used directly for heat. One could argue that that should be replaced at about 1 TWH of fossil fuel burned for about 0.94 TWH of electrical heat but that assumes resistive heating. If a heat pump is used that becomes 1 TWH of fossil fuel burned for about 2.5 TWH of electrical heat. So 71 TWH of fossil fuel heat can be replaced by 28 TWH of electric heat.
Your graph shows about 600 TWH of coal and gas but that can be replaced by about 233 TWH of renewables.
