Putting all the eggs in the solar basket has risks, too. Like a large volcano eruption that reduces the amount of light that reaches the surface for a few years would be a double whammy, affecting food production as well as electricity production (which we'd need to rely on to try to offset the food losses). If we're instead facing brownouts or full blackouts, that's a recipe for a complete loss of stability. I suspect less solar energy reaching the surface would also reduce total wind energy (less localized heating would mean lower pressure differentials, but I could be missing other significant parts of this equation).

I'd be most comfortable with a nice mix of energy sources combined with mothballing instead of decommissioning some capacity as renewables are able to take over more and more of the day to day energy needs so that we're prepared to deal with an emergency like that.

I'd also like to see more food production moved to vertical farms that can be powered by electricity rather than relying entirely on the sun and weather. But I do understand that the scale of food production would make doing that with a significant portion of the food supply very difficult. But with climate change (plus nutrient depletion of the soil), keeping so many eggs in the "just keep farming" basket also doesn't seem like a great idea.
