Almost 50% of residential energy usage is HVAC and Hot Water heaters.

I see no reason we couldn't use excess solar during the daytime to heat our hot water heaters, or cool/heat the house.

Modern Construction and Water Heaters have great insulation, and its possible to use the `cheap` electricity during peak solar to store as heating/cooling.

Heat pump technology has come an amazing way, as well!

Switching to an electric heat pump water heater from my natural gas water heater saves nearly as many emissions per year as stopping 12,000 vehicle miles. And it saves money, though it front loads the cost a tiny bit.

We could have a massive economic boom just by retrofitting existing buildings with more efficient and modern technologies.
