Excellent points covered here. No perfect solutions but here's my suggestions: * Stop ignoring the basic's (extremely efficient insulation). We need to reduce the costs of VIPs & VIGs (Vacuum insulated Panels & Vacuum insulated Glass). Wide scale use of these (cars, houses, refrigerators etc) would significantly reduce power demands. * Overbuild off-shore wind farms and rooftop solar. Any surplus energy could be stored (batteries, pumped hydro, etc)--and when these are "full", dump the excess into H2 production. This H2 would be essentially free--since the surplus power would otherwise be wasted. * Get rid of ALL fossil fuel 'base load' power plants. Add small/modular nuclear plants (preferably Thorium) as needed to supplement battery storage. * All EV's should have V2X (vehicle-to-grid, vehicle-to-house, vehicle-to-vehicle) capability. This way every EV (car, bus, truck etc.) is dual use--and thus, a potential mini power plant.

I live in the Pacific Northwest which experienced the heat dome many of our neighbours use oil and natural gas to heat their homes but my household uses a heat pump.

We were so thankful as when the Heat Dome hit we could keep cool 😎 we actually offered our house to friends and family to keep cool as the vast majority people in my city don’t have ac. The government currently gives out thousands of dollars of subsidies to switch people who used natural gas to heat pumps which is relatively green in BC as we use hydro or wind to power our grid.

I can see riots and demonstrations like those never seen before not so far off as workers simply can no longer make ends meet, pensioners especially as the pension increase in April is only going to be about 3% and 3% on the state pension is peanuts and comes nowhere near to covering the huge energy price increases with similar increases in the Autumn, rapidly rising food, clothing and petrol increases, along with just about everything else that only fuel further increases. The energy companies in the UK are going to end up being owed hundreds of millions of pounds as a lot of households will run up huge energy bills rather than sit in coats and jumpers in semi darkness in a bitterly cold house and any government that allows them to cut off huge numbers of people because of unaffordable energy bills, which would take them years to pay back at the same time as energy bills become more and more unaffordable for ever-increasing numbers of people is going to face huge social unrest, which is probably why the French Government made EDF shoulder the brunt of energy price increases, the French consumer only having to pay a 12% increase in gas prices and 4% in electricity prices.
