Solar and wind are strategically untenable. I can harden, concentrate and layer my defenses around dense energy production facilities. I can also concentrate my remedial assets to bring them back online asap.
With the solar in particular it's one cluster munition away from massive degradation.
In times of scarcity and uncertainty, strategy becomes a lesser focus than just survival.
It works the same with money: when you barely have what’s necessary to live, you don’t have the reserve to invest/save strategically to improve your situation, and you don’t necessarily have the peace of mind required to think about it.
