As usual, headlines go for the 'big wins' and ignore the detail. If we all go electric heating, and electric cars, where is all this electricity coming from? We need to go back to address needs and wants. New houses need to be well insulated, then either better insulate older houses, or knock down and build new better ones, whichever is more efficient.
But currently around here, so many new houses are being built, but there is no more employment, so we are creating more commuters. Before the car, we all lived close to work, we need a culture change to move us back towards that, where possible. But also remove the desire to keep travelling. So much is done because we can, which we then interpret as a need. I meet so many people who travel a hundred miles for a 15 minute business meeting, then return.
Rail travel instead of cars would help, if only it could cope. Biggest problem is too many people, a long-term plan to reduce population is needed, not involving mass genocide. There's a task no politician will volunteer for.
Some years ago, we had a small house, mid terrace, electric storage heaters, warm 24/7, cheap. Washing machine and dishwasher ran on overnight cheap power too. Always a challenge to set the input for the next day's weather/temp, so as Jock says, sometimes too hot/cold. Always thought a mix of sotorage heaters as background and radiators as top-up might work.
Government heads flying around the world to climate summits is a bit of an irony.
