Too cheap to meter, as long as you have no SLA. Much like solar-generated heat is "too cheap to meter" in traditional greenhouses. Desalination is not sensitive to input power fluctuations, as long as you have a large enough reservoir to even out the spikes. The natural desalination cycle, with evaporation of ocean water, clouds, mountains, and rivers, already worrks like that, but probably a more localized setup with electric pumps and reverse-osmosis membranes could bring freshwater more directly where humans need it. |

For desalinization plants to operate with the sun entirely new massive fresh water reservoirs would need to be constructed.
