  Or import it as gas/liquids from other countries, which probably accounts for the majority of energy in the majority of countries today. EVs and renewables will decrease the amount of imports needed for most countries, but a reduced amount might still be needed for some nations. Only difference will be a less cartelized supply since there's a lot of countries that can set up solar and wind for export.

  The intensity is low, though, and the weather can be rough on panels in the winter. If it's possible to stockpile the energy in fluid/gas form, it's better to produce it in Sahara and then ship it to wherever it's needed.

  For household-scale I only have a proposition regarding storing/generating heat, namely compost. A compost pile produces a surprisingly large amount of heat. If you run a hose through it you can have sufficiently hot water all winter. You could maybe use it to produce biogas and burn it in a turbine, but that's anything but household-scale. As for electricity you won't find anything better than batteries at the moment.
