Easy just tax the rich more, tax carbon, subsidize EVs

> Exporting your CO2 emissions to other countries (in the form of battery manufacture) This does not make sense. Battery manufacture is no way equivalent to ICE emissions.

>Battery manufacture is no way equivalent to ICE emissions. How is it not? It takes a huge amount of energy to manufacture a battery pack (you spend about the first 1/3rd to 1/2 of an EV's life paying off the "CO2 debt"), and it generates all sorts of pollution in the process.

Because they are two completely different things. One is the environmental cost of manufacture, and one is the environmental cost of usage.

Electric and ICE vehicles both have both of these costs. They are all different. If you want to compare things, you need to actually look at all four numbers, not take two unrelated numbers and comparing them for dishonest reasons.

I'm aware of those numbers, and they are still both an environmental cost, regardless of how they happen. EVs swap high environmental running costs for high environmental manufacturing costs, and then we in developed countries externalise those costs by sourcing most of the component parts from other countries, and tell ourselves that we have done something great for the world.

Edit: It takes 25MWh to manufacture just the battery pack for a Tesla, or about 18,000Kg CO2 (assuming a 0.6Kg/kWh CO2 ratio for the Chinese power grid, which is a very optimistic number).

Assuming the power grid where the EV will be used is 100% sustainable (which is very very far from the truth), given that the CO2 output for gas/petrol is 0.3kg / kWh or 2.3kg / liter, and assuming an average of 35 mpg or 7.7 miles per liter, as well as adding a factor of 1.5 to account for refining, storage, and transport losses (which I think is very generous) you would have to drive your new Tesla for around 40,000 miles on 100% renewable power before you've paid off the increased CO2 debt of its manufacture over an ICE. That mileage, by the way, is the number of miles the petrol-engined car would have to drive to produce the 18,000kg CO2 that it took to manufacture the EV battery pack. I am also assuming that the manufacturing cost of the rest of the EV is comparable to an entire ICE car, which I think is fair, as EVs generally contain a lot more electronics (which are very energy-intensive to manufacture), as well as at least one electric motor. An ICE is basically a lump of metal, which has a surprisingly low relative cost of manufacture.

The UK has a relatively "green" power grid, for a developed country, and even here, the difference in CO2 output between the grid and an ICE is so small, you would basically never break even in overall CO2 emissions between an ICE and an EV. For reference, the calculated CO2 output of the UK grid is 0.23kg/kWh.

Also, just for fun, the embodied energy of a 1960's Fiat 500 (assuming its entire 500kg weight is made of steel, which is probably a good enough approximation) is 3MWh, or three laptops.

So what is more sustainable? Claiming that I am making an "dishonest comparison" just ignores the issues with the "green maths" of EVs.

Petrol cars have significantly longer driving range, which is important for transport efficiency. Petrol cars are significantly cheaper to buy. Petrol cars refuel significantly faster than electronic cars recharge. Petrol cars don't have a costly battery which degrades over time and pollutes.

- Very few trips are long enough to deplete an EVs battery - EVs have significantly lower Total Costs of Ownership - To refuel your petrol car, you have to make an extra trip to the petrol station. While your EV is simply charged where it is parked overnight - The extraction, refinement and transportation of petrol pollutes way more than that EV battery will

> - To refuel your petrol car, you have to make an extra trip to the petrol station. While your EV is simply charged where it is parked overnight

I have yet to see an apartment building with more than a couple of charging stations, if they have any.

On the street where I currently live, half the houses don't have driveways. Assuming you can park in the same spot on the street every night, are you going to run an extension cord from the house to the street?

(It's not an "extra trip," it's a stop when I am going somewhere.)

I don't like to discuss EVs in public because things quickly devolve into an inquisition if one doesn't fully embrace the messaging, but I'll bite. From an enthusiast perspective, I have no issues with an electric powertrain. The concept has a lot of promise once the implementation matures. The current issues I have with electric _powertrains_ (not vehicles) are: Relatively short battery lifespan, high replacement co…

>As for the environmental aspect, well, I'm probably going to regret saying this openly. We live in a fully industrialized world. Unless we're all willing to go back to using wind power to transport cargo and carriages to transport people, while simultaneously getting the world population back to pre-industrial levels, it's a bit too late. I don't think you're going to be saving anything with your EV. The messaging a…

> It's definitely not too late, this sort of defeatist attitude is not only wrong but dismissive of the dangers.

I'm not suggesting _nothing_ be done and we carry on as usual. But there are 7.6 billion people on this planet and nearly every single one of them either has, or is working towards a modern standard of living. You can't go from 600 million people in 1700 to 7.6 billion people in 2021 without severely harming your ecosystem.

11,000% more people, and each one of them uses _far_ more resources than their 1700 equivalent. They didn't travel except by muscle or by sail, they consumed locally produced food or food imported by sail and muscle power, and the most technologically advanced good available to the average person was an oil lamp.

There isn't an electric car, reusable bag, ethically produced wool sweater, or synthetic burger that can get you back to anywhere near that kind of resource usage.

As for the dangers, I'm aware of the worst case scenarios and the best case scenarios. They're all terrible. At worst, we die out, at best we end up struggling to maintain a comfortable existence due to shortages and a fragile ecosystem while reminiscing about the good old days. But we need to look at the problem clearly and realistically and work towards feasible, realistic _mitigations_ (solutions are impossible) rather than passing nonsense populist laws like banning plastic straws or electric car subsidies and hoping the next generation figures it out.

> This is also dead wrong, a quick switch to EV will substantially reduce the amount of carbon pollution, no need for mass killings. We simply need the government too provide right incentives to switch to cleaner and less energy usage

I'm not opposed to this, and I certainly don't advocate mass killings (see above re: realistic mitigations). I do realize that the lifetime emissions of an electric car are lower than most ICE vehicles. But again, this isn't a solution. You still need a lot of infrastructure and a lot of emissions to manufacture, install, maintain, and eventually replace that infrastructure. Sticking a solar panel on every roof and a wind turbine in every neighborhood isn't going to solve the fundamental problem of "organism is using resources in an unsustainable way".

A quick, forced switch to EVs is going to win the "carbon emissions" line-graph competition so we can all virtue-signal to each other about how well our countries are doing, but it's not going to get us out of the hole we dug, even when combined with _all_ the current popular emissions reductions proposals.

Those numbers (18,000Kg CO2) do not seem to line up with what is researchers have reported.

Thank you for this. I don’t see how we make any significant changes to our trajectory without accepting a “lower” quality of life than what we have now. We need to localize, we need to rid ourselves of continuous consumption of useless junk, and we need to reconnect our resource use to the planet that sustains us.

None of that is accomplished by the virtue signaling you mention of replacing one luxury item with another different one.

Tax the rich more, tax carbon, and build trains and buy buses. Stop subsidizing single occupancy vehicles which are a huge resource waste even if electric. Why as a society do we want to subsidize a vehicle that is going to spend 95% of its life parked when we can build common transportation that everyone can use?

I'm gonna write what I'm writing every time this comes up.

I live in Munich, a big city in Germany. I know zero people who live in an apartment (like I do) who can reasonably use an EV. All the friends and acquaintances who own an EV have a house with a garage, and thus they have no problems charging (incidentally none of them reside IN the city with their houses, because they're not millionaires). I'd have to go the supermarket parking lot, which is the only charging spot in a 1km radius that I know of. I don't think (although I haven't asked) if the building owner would be up for putting up charging in our parking lot. I somehow doubt it.

I've yet to hear any even remotely sensible solution.
