The obvious and safest solution is nuclear energy.Nuclear plants can be made far safer now with much less waste product. But nuke is received with horror by the Left because it IS the cheapest and best. De-growth and de-population is the goal of the Left, not efficiency or clean safe growh and prosperity.
But you can’t carry a nuclear reactor in your car and there isn’t enough copper in the world to electrify the US for transportation purposes and lithium batteries are only about 6% as efficient as a gallon of gas.
I agree that nuclear is the best option on an industrial level, but for electricity, we are limited to powering our houses and not our cars.
