* '''[[Solar panels]]:''' Only if they can be made cheaply [[solar/challenge 1|without scarce minerals]] (it's ok if the efficiency is lower). Need to mass produce enough to cover every [[rooftop solar|rooftop]]. Need [[energy storage]]: [[sodium-ion batteries]] or similar. | * '''[[Solar panels]]:''' Only if they can be made cheaply [[solar/challenge 1|without scarce minerals]] (it's ok if the efficiency is lower).

* '''[[Wind power]]:''' Only to generate [[hydrogen gas]] (which can be used as fuel instead of [[natural gas]]). Otherwise too intermittent, too far away for power lines. | * '''[[Wind power]]:''' Only to generate [[hydrogen gas]] (which can be used as fuel instead of [[natural gas]]).
