For [[homes]]/buildings{{x|connected together via the power grid for some load balancing}}, [[rooftop solar]] would provide enough "general-purpose" electricity, but not always enough for [[heating]]. | ||

There would be battery [[electric vehicles]]{{x|mostly sodium-ion, because [[lithium-ion]] battery minerals are too scarce}} and hydrogen-based vehicles{{x|mostly [[hydrogen combustion vehicles|combustion]], because fuel cells are too high in platinum-group metals}}. | |||
In any case, it becomes a lot easier if we '''[[public transit|drive]] [[walkability|less]]''' (some careers are an exception obviously) and '''[[frugalism|buy less]]''' new stuff. Those factors alone account for 2/3 of the world's [[energy]] consumption. | In any case, it all becomes a lot easier if we '''[[public transit|drive]] [[walkability|less]]''' (some careers are an exception obviously) and '''[[frugalism|buy less]]''' new stuff.
