We also thought that about oil at one point, woefully underestimating the human appetite for cheap energy, for which we’re just now paying the price.

Burning them is a monumental waste of perfectly good and useful organic compounds.

Juggling the changing demand for gasoline over the next decade or more is going to be an interesting challenge, because when you refine crude oil, you’re separating it out into several different fuel and feedstock compounds, and the amount of crude you need to refine depends on the demand for that particular fraction. So if you reduce gasoline output, you’re also reducing output of things like diesel, propane, kerosene, fuel oil, asphalt, etc. if the demand for any of those doesn’t drop along with that of gasoline (or demand for gasoline stays steady while it drops for other fractions), you end up with oversupply or undersupply (which is a major component of why diesel costs have soared relative to gasoline). If demand for diesel, jet fuel, and ship fuel oil stays steady while gasoline drops, the cost of gasoline is going to crater, changing the economics of BEVs. Now add in biofuels, which change the demand for petroleum fractions, and it’s gonna be a wild ride for a few decades.

How did you manage that calculation? I found the average gas emissions to be 1t of CO2 per 2500mi. So 16t of CO2 should actually be 40,000mi.

And that's only because you're taking the worst case for a Model 3 battery when the best case is actually 4.5t. While the mean is apparently closer to 5t, even if we take the median of 10t it's still a lot less CO2 at 25000mi.

Don't forget about the CO2 cost to extract, process, and transport that fuel all the way to the pump too. Actually makes the gas numbers way worse.

Plus a gas car has a lot more components in the drivetrain so the rest of the vehicle production is a bit more CO2 intensive compared to an EV as well.

Also considering batteries can be (and are being) recycled, the need for mining new battery materials will start to slow down, and maybe eventually can stop entirely.

So even if you're being pretty generous to the gas car and somewhat unfair to the EV, the gas car will overtake the EV on CO2 after 5 years.

Sadly most people don't know how bad and shorthanded the foster system is. A lot of the kids aren't even in homes, they're in group homes because there arent enough families.

It's why they've been removing way less kids from homes, especially where it's like mild neglect from drug addict parents, etc, because the alternative is rarely better.
