> I'm basically a non global warming type This is nonsense, global warming is real and it's implications are visible already. Whether we are smart is irrelevant when we are lazy, selfish and greedy.

Noise pollution, local air pollution from exhausts, and local air pollution from tires are all far more directly costly to human wellbeing at scale than water use in lithium mining.

The Eevee revolution will probably be salt water batteries anyway

If you placed a weightless empty box on your head and filled it with the average cars exhaust emissions for one year, the result 4.6 metric tons would crush you like a pancake.

If we're being charitable we could let you take a few breaths of what's in the full box just to ease your suffering.

There are 1.4 billion such cars currently operating in the world.

A few things that should probably be taken into a account as we move to an electrified future is 1) what is the carbon footprint of an EV vehicle when we are recycling batteries 2) what is the carbon footprint of an EV as we increase efficiency/range 3) what is the carbon footprint of an ICE as they increase range The reason this might be interesting is that EVs, I believe, are still in their infancy and are likely t…

Most cars are still sold without turbocharging. We are nowhere near maximizing combustion vehicles. That 100hp/l is somewhat in contradiction to your arguement.

The wide array of technologies for injection and burn efficiency are still largely unadopted as well.

The replacement costs of batteries at ~5-8 years of ownership are always conviently absent from the comparison between EV and combustion. No surprise.

EV are not in their infancy either, the first EVs are from over a hundred years ago and there have been models available since the 90s from major manufacturers

Those are all good questions, but the answers are already well-understood EV’s already win on all of those metrics, hands down, even in parts of the US with lots of coal power plants, including CO2 emitted during manufacturing:

I copied this from a climatologist's twitter last year but can no longer find the source, I suspect they've deleted their account: > All other things being identical, if an EV made from metals that were processed with green electricity only has one (1) order of magnitude less emissions than a petrol engined vehicle of the same size over the vehicle's lifetime, the equivalent EV where the metals were smelted with coal…

A 50% reduction in emissions in the short term is barely enough to stay on track to not destroy civilization in our own lifetimes. We should take the order of magnitude win! (Even if it is “only” really the 70%, from that sibling comment)

Also, carbon capture will eventually exist at scale, and cutting CO2 production by 90% will cut carbon capture costs by 90%z

Wrong question, the right one is: How to make 10 billion people live with decent life standards and comfort without destroying the planet?

The standards probably have to be really lowered... If we believe this data[1], one would have to live like a resident of Sri Lanka, Jamaica or Myanmar so that 1 earth is enough per year (other countries are available). Pessimistically, with the planet we currently have, not all 10 billion can live decently, and the minority who control the weapons would probably rather resort to violence rather than share things equ…

I generally refer to the framing offered by https://goodlife.leeds.ac.uk/

Nonsense. A ton of steel produced with coal produces about two tons of CO2. If produced from recycled steel, it produces about 0.4 tons, but let’s say 0. So a two ton EV (like the Tesla Model Y) would generate 4 tons more CO2 than a similar ICE vehicle made with “green steel”. That ICE vehicle will generate more than 4 tons of CO2 every single year of its existence.
