Ah, but one enhances the other. Solar (and wind) both suffer from the intermittency problem: both do not scale up or down to match demand peaks and troughs for electricity. Also the 'amount' of sun and wind varies geographically. So the two solutions are: - Build roughly 6 sets of geographically distributed wind/solar farms (with 6 separate sets of transmission infrastructure) to handle base-load demand reliably. Expensive. - Attach a whole bunch of batteries to the grid to smooth out demand. Also (currently) expensive. I think Elon Musk's solution is to convince enough people to buy huge battery packs that they occasionally drive around, but mostly leave plugged in to the grid. |

Musk's plan is also to sell literal battery packs that attach to the wall, provide for expansion, and work in tandem. Which he is already doing.
