Now how to shift energy from noon to evening, or demand from evening to noon?

Energy for hot water can just be stored in the form of hot water. Cooking on the other hand need too high temperatures for that, maybe hydrogen is the solution here, the beauty of using it for cooking is that you don't need an expensive fuel-cell like when using it for electricity storage. And since you don't need small tanks like in a car, lower pressures can be used and a lot of the waste with compression can be avoided.

And the McMansions with low thermal mass, black roofs and huge interior spaces? Perhaps it's time to admit that they were a daft idea all along. We instead need houses with less interior space, with more thermal mass, that are white and even mirrory from all the angles that the sun sees them, that are more connected to nature - and by nature I mean all the free thermal mass of the ground.
