Heating and cooling can only be offloaded in extremely wellinsulated houses. A lot of the ones in the UK do not make the cut. Even some new EU ones do not. If you try to offload it otherwise you just waste power heating/cooling yourself at wrong hours. A boiler in this setup is a thermal battery. These are good, but space consuming and relatively failure prone and expensive to maintain. Inefficient compared to central too.

Are you arguing for or against offshore wind? Tackling climate crisis requires All The Above. Wind, nukes, solar farms, tidal, whatever, by themselves, aren't silver bullets. We also need heat pumps, renovations (insulation, air sealing), district heating, etc. That's just for housing. We could also talk all day about industry and agriculture. As the saying goes: The opportunities are insurmountable!

  Nuclear power is indeed a silver bullet. France supplied > 85% of its electricity demand with nuclear (with the rest being filled by pre-existing hydroelectricity). As is hydroelectricity and geothermal power for those countries with the appropriate geography. E.g. Norward produces 100% of electricity through hydro. Non-intermittent sources of energy don't need to be supplemented by alternative sources of energy.

    Whenever a cold spell hits France 10 GW of fossil production is started and 15 GW of exports turns to 5 GW of fossil based imports. The French grid would collapse without 30 GW of fossil based production to manage cold spells.

      Using absolute units instead of proportional figures is deceptive.

        Why are you lying then? Why are you attempting to shift the topic? You said: > Non-intermittent sources of energy don't need to be supplemented by alternative sources of energy. Like I said the. The French grid would crash during cold spells if not supplemented with 30 GW of fossil fueled power production.

        They could always build more nuclear plants to fill additional demand. Again, non intermittent sources don't need supplemental sources of energy, as long as there's sufficient supply. By comparison, a country cannot possibly run their grid entirely with solar on account of intermittency. I'd suggest reading people's comments in greater detail, before accusing people of lying.

        So now you suggest that we should build peaking nuclear plants in an attempt at covering your previous blunder with pure insanity. Lazard expects peakers to run at 10-15% capacity factor because you know, how often do we have cold spells in France or whatever other reason causes them to run? A couple of weeks a year at most. Lets say 15%. Lets calculate what Hinkley Point C costs when running as a peaker. It has a CFD at $170/MWh for 30 years. Lets assume it runs at a 85% capacity factor and that $20/MWh are O&M costs. 153/0.15 + 20 = $1040/MWh You want to solve the problem by forcing electricity costs on the consumers at double of the peak of the energy crisis. All because you view the world in nuclear fanclub fantasy land glasses.
