 ==Vehicles==
-No matter the energy source, gasoline cars and diesel trucks would need to be replaced with [[electric vehicles]] and/or [[hydrogen]] vehicles. So in any case, [[energy storage]] is needed.
+* [[EVs]] with '''[[sodium-ion batteries]]'''
+* '''[[Hydrogen combustion vehicles]]''' - {{light|using [[hydrogen gas]] produced by surplus [[wind power]]}}

+'''Things that ''won't'' work'''
+* The status quo (mostly gasoline cars and diesel trucks)
+* EVs with [[lithium-ion batteries]] (too much '''cobalt''') {{x|This is true even when manufacturers brag about batteries having "only" 3% cobalt. Not low enough: It would have to be less than 1% - otherwise, cobalt scarcity is still the most limiting factor in scaling up EVs. See page on [[lithium-ion batteries]] for more details.}}
+* Hydrogen [[fuel cell vehicles]] (too much '''platinum''' or '''palladium''') {{x|Note that hydrogen gas ''production'' also needs these metals, but the fuel cells would need [[hydrogen gas#Platinum-group metals|7 times more]] on average}}
+'''Things that could ''somewhat'' work'''
+* EVs with [[LFP batteries]] (no cobalt, lithium-based; still not as scalable as sodium-ion)

 ==Analysis==

+* [[Energy supply solutions summary]] - the likely answer, but still unconfirmed <!-- TALK: Is this redundant tho? -->
