A lesson being learnt in the Middle East and Eastern Europe right now is that any form of highly centralised energy generation (or energy processing) is hugely risky during a war. It's an Achilles' heel that makes modern economies hugely vulnerable when attacked, even by a mid-power like Iran, let alone a super power.
replySolar and wind have been branded as unreliable by propogandists working for billionaire fossil fuel magnates, oil sheiks, and oligarchs.
The converse is true: distributed power generation and storage is incredibly robust and can easily meet the needs of our civilization even under active attack.
If you want long term thinking, if you want robustness over short term profits, then solar + wind + batteries are you answer.
No super power can blockade the sun and wind.
No super power can blow up every rooftop panel without also nuking entire cities.
