While impressive to be boring electricity use was about 30GW but direct heating by gas and oil consumption was another 150GW or so. Heat pumps might reduce tha

  If I understand it correctly a heat pump would have produced the same heat with 1/3 the energy? Yeah a long way to go but considering we are only really at the beginning of the green energy revolution this is all great news. It affirms that we can do it.

    Yes, and a heat pump tends to run at lower output for longer periods of time versus traditional fuel fired boilers so the peak power demand would be even lower still.

    Can confirm that in my 1920s house, now with heat pump, my energy use is now a fraction of what it used to be, since replacing boiler with heat pump. Before: Jan 600kWh electricity, 3300kWh gas = 3900kWh After: Jan 1580 kWh electricity, 20kWh gas (cooking hob) So in total, 41% of previous amount, and for heating, 30%. So yes, for crappy uk houses heat pumps are totally fine. Adding in solar pv, and a time shifting battery, and the bills are maybe £2k per year lower than they would be.
