Living Off the Grid

The answer to this question is no.

Obviously if you’re one of the tiny fraction of 1% of the world’s population who lives in a house like the one shown here, you have no choice, but you do have some interesting options in terms of renewables.  With all that water around you, wave power, tidal, and ocean current may work very well, in addition to, of course, wind and solar.

FWIW, sodium-ion batteries have been around for 50 years, but lost out to lithium.  Some people say that they’re coming back.
