Seems like a good time to (slowly) start shifting investment from production into storage (maybe also if you've got stock in renewables).

It has been calculated that a supergrid alone without special off-the-grid energy storage could potentially eliminate any need for fossil fuels for electric production.

However, my best guess is the best strategy would be to combine supergrid with off-the-grid energy storage and that off-the-grid energy storage should use either flow batteries or magnesium-sulfur batteries (which have yet to be properly developed).

There is also the currently massively under exploited marine current power;
