Oil is used for more than just energy.

[-] frank@sopuli.xyz 8 points 2 days ago

Idk why you're being downvoted. Petrochemicals are used for a bunch of stuff, including plastics manufacturing.

We should switch to renewables as quickly and completely as we can, but it wouldn't eliminate 100% of oil use

[-] MonkderVierte@lemmy.ml 5 points 1 day ago

I argue that if oil wasn't as cheap, ecological alternatives to plastic would have a chance or would be considered at all.

No, they wouldn't. Capitalism is driven by supply, not demand.
If by some magic we switched to renewables over night, the owner class would open or expand another market to keep those ships moving.

[-] philpo@feddit.org 6 points 2 days ago

Yeah, that worked totally well for the Guano and sodium nitrate businesses.

Yo, you right

[-] Track_Shovel@slrpnk.net 2 points 2 days ago

I'll allow it.

As nice as it would be, a not insignificant amount of coal being transported is destined to steel production. Steel is iron + carbon, and the easiest source of carbon is coal. Steel is pretty important, so that's not going away anytime soon. I wonder if carbon capture could make a product that could be used to replace coal here though, and fairly effectively sequester the carbon in an actually useful form?

What biomass grows the fastest without being waterlogged - I imagine bamboo or sugarcane or something

Grow that, and burn it to make carbon neutral steel; bonus points if you do it in a highrise/underground farm but frankly some medium term reversible environmental damage is preferable to killing off way more with climate change

[-] Phineaz@feddit.org 3 points 2 days ago

Eh, purity is a thing. Biomass is the opposite of what you want there, but it could be doable. I do wager, however, that the largest "climate cost" of steel comes from the repeated melting of the steel.

[-] 1rre@discuss.tchncs.de 5 points 2 days ago* (last edited 2 days ago)

Coal has a bunch of impurities compared to charcoal I thought?

And if the repeated melting is done by burning biomass/charcoal or with clean(er) energy then it's not a huge issue

[-] JacobCoffinWrites@slrpnk.net 1 points 1 day ago

Electric Arc Furnaces are probably our best bet for that - they're an established, proven technology and can be swapped over to a green power source without any other changes (assuming the society has the energy capacity). I think I remember reading that a factory somewhere in Europe had already done that but a quick search has failed me.

I don't know about all of you, but I know I wouldn't want to cross oceans without a good engine.

Storms are not cool. Not being in the age of sail anymore seems good.

[-] dejected_warp_core@lemmy.world 3 points 1 day ago

You say that, but modern sail concepts are a thing and are already in place as hybrid shipping solutions. Boats require a LOT of energy to do their thing, so any savings translates to big numbers.
