We use oil because it’s cheap not because it’s the only possible solution. It’s not that we’re going to run out 100% year X, it’s that as economies of scale end priced inherently spike. Gas stations can scale down to 1940’s levels by having most of them close, but giant fuel refineries, pipelines, etc need scale to be worth the maintenance.

- geysersam 2y agoFor some things fossil fuels is still the only feasible (meaning, remotely close in cost) solution. Air fuel and fertilizer comes to mind.
- Retric 2y agoNot when we start talking 4x or more the price. The cost premium of biofuels for air travel aren’t that high and the scale can meet demand for long distance flights. Fertilizer from nitrogen in the atmosphere is again cost competitive relative to that kind of increase. Batteries are fine for ocean shipping on a ~50 year timescale, and that basically covers burning fossil fuels. Using it as a feedstock for plastics etc is a non issue for climate change.
- vlovich123 2y agoYou're basically arguing for the latest estimates for peak oil. Maybe they're right this time but I still think that improving technology & prices make new sources available. > Who is going to pay the equivalent of 50$/gallon when they can use an EV? If we're going to be arguing for peak oil, let's argue for peak lithium then too. EVs are going to get more and more expensive too as we have to extract from more expensive lithium stores. > We use oil because it’s cheap not because it’s the only possible solution For some things sure. Aviation fuel and ship fuel notably don't have any real replacements on the horizon. From your sibling comment: > The cost premium of biofuels for air travel aren’t that high and the scale can meet demand for long distance flights.

Batteries are fine for ocean shipping on a ~50 year timescale, and that basically covers burning fossil fuels. Using it as a feedstock for plastics etc is a non issue for climate change. I think you're mistaken here. Biofuels for air travel are much more complex than just pricing. You've got regulatory approvals, cost of retrofitting existing engines / figuring out how to make them drop-in without needing petroleum, etc. If you're thinking that batteries are fine for ocean shipping, I'd like a sample of what you're taking because the energy demands of massive ship containers dwarf the capabilities of batteries. That's why they're talking hydrogen fuel cells and nuclear. > It’s not that we’re going to run out 100% year X, it’s that as economies of scale end priced inherently spike. Gas stations can scale down to 1940’s levels by having most of them close, but giant fuel refineries, pipelines, etc need scale to be worth the maintenance. Conversely, there's a huge incentive to have oil be competitively priced and avoid a total collapse of that segment. That's why you see huge resistance politically - there's no real plan put forward for how we transition to a clean energy economy for the people currently participating in the oil economy.
- Retric 2y ago> Peak lithium Oil is consumed, lithium isn’t. There’s plenty of lithium to electrify the world multiple times, but it’s just an element so you can literally recycle it for billions of years. > You've got regulatory approvals, cost of retrofitting existing engines / figuring out how to make them drop-in without needing petroleum, etc 0.2% of global aviation fuel is already biofuels, the regulatory processes is already involved and we’re talking a 50+ year timeframe here there’s plenty of options without retrofitting existing aircraft. As to boats, weight and volume are a non issue so they scale just fine into the 24,000 TEU behemoths. Upfront costs are prohibitively expensive though operating costs are presumably. That said, there’s many options, ships are one of the few cases where hydrogen is a realistic possibility.
- vlovich123 2y ago> There’s plenty of lithium to electrify the world multiple times, but it’s just an element so you can literally recycle it for billions of years. Recycling lithium is typically more expensive than extracting it through mining. Recycling companies claim a recovery rate of 95-98% so certainly lithium is lost and that's ignoring that smaller batteries often don't even end up in the recycling stream. But the important bit is the cost - if it's more expensive than mining then the recovery isn't economical then either there's a government subsidy or the lithium ends up diluted in the trash stream. You'd have a point about nickle or cobalt because they're particularly valuable but lithium is not so it is effectively being consumed. > 0.2% of global aviation fuel is already biofuels But it's not even clear that biofuels reduce CO2 due to production, processing & transport as well as land clearing for scaling it up. [1] suggests that biofuels can actually end up emitting more CO2 than the fossil fuels they replace (for example here's an earlier study [2]). And that's ignoring the substantial scaling challenges that SAF faces on the production side. I hope it works out but the lesson with huge risky bets is that many don't pan out and all we have now is large risky bets left which makes me pessimistic we'll succeed just because we run out of oil (assuming we even do which again seems highly unlikely to me because that's not how economics works).
