With some nuclear capacity, electric heating makes the most sense. Just let off-peak boilers use that off-peak nuclear electricity.

The problem is, a lot of people want to push 100% renewables.

Solar overproduces in summer and wind has strong days and weak days. Batteries are economically great for short term energy storage (i.e. charging and discharging at least once a day and profiting off of those arbitrages), but they will always be way too expensive for seasonal or multi-day storage. Imagine paying a very cheap $50 for a kWh battery in 2030 and only cycling it 50 times a year. Over a decade, that’s an insane 10c per kWh just for the battery, excluding all other generating and financing costs.

The only way out is to have the windmills generate hydrogen on windy days and then push the hydrogen through the old natural gas pipelines.

And you’ll have to subsidize it, because economically it will never be very competitive.
