Here's an idea: Build out massive solar and wind power capacity and create electricity for the grid. Use specially designed desalination plants which operate well at low utilization and significant swings in production to smooth out the peaks in the solar / wind production curves. Excess power is converted into clean water. Water seems like a reasonably good place to "store" the value of the energy you just created. Furthermore, what is the value of having a somewhat more predictable power supply from solar and wind resources?
