Consumers will be able to use them to generate electricity and warmth

Cogeneration is one of the good ideas that should be used more. Note that cogeneration with solar is also possible, with PVT (photovoltaic thermal) designs which use the heat also. These run around 70% collection of solar energy. However, whether PV or thermal, storage is needed! For the thermal aspect, search on "seasonal heat storage" which is being used a number of places. As usual, to be effective, we need to change our thinking from that of spending for to that of investing in.

Disclosure: in our spare time, the house is being modified to store attic heat into the soil underneath. Slow work, but do-it-ourself is affordable! An low cost variation is fans to blow summer air through the basement into the house. Don't forget the dehumidifier if you do this.
