I'd love to see an investigation into fossil fuel accumulation over geological time scales - especially petroleum.

From what I've seen, 10,000 barrels per year is a reasonable guestimate.

If that is the case, then just the electrical energy harvested from solar panels in the UK could convert air into fuel at a faster rate than the WHOLE earth (on average over geological time scales) (as long as the fuel conversion/production was at least 1% efficient at converting electricity to fuel).

From what we know it's a very lumpy distribution. Most of the fossil fuels were created in a few specific points of history

The thing is that the supply of fossil fuel depends one's willingness to spend effort finding it. There's a virtually unlimited amount of methane on the ocean floor but harvesting it is not economically viable (fortunately).

US fracking technology allows otherwise unavailable heavy oil to be harvested but naturally at a higher price than Saudi light crude.

So solar tech, as it declines in cost, will replace a larger and larger portion of fossil fuels but not the entire spectrum of these some come out of the ground close to the form we need them in (solar asphalt is hard to imagine with subsidies).

Random question and memes-aside, is there oil on other planets?

Edit: GPT says hydrocarbons yes, oil as in Earth no (because that comes from complex living matter).

Edit 2: As far as we know, I really hope there's more life out there.

solar panels dont convert air into fuel
