I'm starting to wonder whether the conventional wisdom of reducing carbon emissions in favour of more electricalisation is really solving the actual problem. As is often pointed out on HN, electrical cars are substantially heavier than their fossil fueled alternatives, and generate other pollution along the way. Furthermore, we're digging our lithium brines from the environment, without really understanding what all this lithium will do once it's leached out into the environment or what impact the mines themselves will have.

With the recent advances of turning CO2 into other substances, such as propane, should we be focusing more on closing the carbon cycle and simply be producing fossil fuels from the waste products of yesteryear?

Naively, it feels like we understand C, O and H, better than we understand some of the rare metals we're now introducing in the name of climate change.

EVs also don't solve the other issues with cars.

Like how deadly they are, microplastics and pollution from tire/road wear, noise in residential areas, the huge waste of area, expensive upkeep of infrastructure, how they make cities less inhabitable etc etc.

> how they make cities less inhabitable

Everyone says they would love to live in a walkable city, but for some reason, at least in the US, the biggest gainers in population over the recent decades have been all automobile-centric cities (which are probably more accurately described as a large patchwork of suburbs). NYC would have shrunk due to out-migration to other places if it wasn't for foreign in-migration[0]. Chicago lost people 15 out of the last 20 years[1].

> at least in the US

Well the US is never a good example for that, because the US notoriously completely screwed up their city planning w.r.t. cars.

You need to look at examples of cities that were not built around the individual cars to check whether that's possible or not, and whether people like it better or not.
