Everyone knows that electric vehicles are supposed to be better for the planet than gas cars. That's the driving reason behind a global effort to transition toward batteries.

But what about the harms caused by mining for battery minerals? And coal-fired power plants for the electricity to charge the cars? And battery waste? Is it really true that EVs are better?

The answer is yes. But Americans are growing less convinced.

The net benefits of EVs have been frequently fact-checked, including by NPR. "No technology is perfect, but the electric vehicles are going to offer a significant benefit as compared to the internal combustion engine vehicles," Jessika Trancik, a professor at the Massachusetts Institute of Technology, told NPR this spring.

It's important to ask these questions about EVs' hidden costs, Trancik says. But they have been answered "exhaustively"


her word


and a widerange of organizations have confirmed that EVs still beat gas.

Not surprising. There has been a pretty successful campaign by the right to paint EVs as worse for the environment because we get our electricity from coal (we barely get anything from coal) and mining; more expensive to fuel up (using the highest priced fast charging vs lowest price of gas); and worse from a humanitarian perspective (cobalt mining).

Things to refute this: EVs, even with coal power as their energy source, emit less CO2 over the lifespan of the vehicle compared with gas vehicles. Mining sucks and is indeed environmentally damaging but oil is also fucking terrible. The benefit of EVs is that the vast majority of a battery can be recycled whereas oil is single use. So to meet a consistent demand, we do have to ramp up mining but once the demands is met, mining can be scaled back dramatically.

For fuel costs, it's easy to do the basic math but many don't. I've seen people complain that their electricity bill will just skyrocket. When I suggested my parents get a battery powered riding mower, my mom thought they would be more expensive and that the electricity bill would be just as much as the gas bill. The price of the mower is the same and the electricity cost was about 1/15th of what has is and you don't have to be riding around in gas fumes.

As for the humanitarian angle, the right obviously does not really give a shit. You could easily point out the atrocities that oil companies have done over the years. You could also point out that cobalt is being phased out. We could also do the mining here instead of having our done abroad. And there is the previous point that most of this just had to be done once then mining can be scaled back.

Hybrids actually have the best longevity and repair scores, however.

The longevity of the vehicle actually does count towards its ecological impact, because if you have to replace it sooner, you're creating a bigger ecological impact of creating a short-term use device before more energy has to be used to recycle parts of it.

So, at the moment hybrids win that battle. I think its simply because hybrids have been around longer, not because they're special. Give it about 10-15 more years and I think you'll see a flip to EVs taking over that spot from hybrids.

EDIT: Also, the bad build quality of Teslas and the early adopters of EVs mostly being Tesla owners also means that the sample of hybrids having better longevity and repair scores is impacted by Tesla specifically being so bad. If you cut out Teslas from the equation, I bet EVs and hybrids would probably have similar longevity and repair scores.

Where did you get that info about the hybrid longevity, an episode of Comedy Bang Bang? Could it be due to hybrids not running the gas engines full-time (less wear hours of usage per mile) ?

The only hybrid I've driven tends to run the engine more as a power generator than to drive the wheels, and often uses no gas engine. I could see how the engine would be less worn from that kind of usage vs driving the wheels all the time.

I was always under the impression that the source of the electricity to charge electric vehicles matters greatly. Some areas use coal burning to generate power while others use hydroelectric.

[-] szczuroarturo@programming.dev 5 points 9 months ago

It does matter in terms of how much less polluting it would be. Even in case of coal plant bonansa it reaches a point where it becomes less poluting than gasoline car . Alghtough much slower. Its also not realy important since renewables became so cheap that there is practicly no country that dosent have a fairly significant renewable share ( and by that i mean > 10 % ).

If you got the most ridiculous EV (the Hummer) and drove it primarily in West Virginia (86% coal generated electricity), it would have worse lifetime CO2 emissions than an ICE.

Literally any other combination, and it's better.

[-] Silentiea 5 points 9 months ago

And it would still be worlds better than the worst ICE cars, it would only be worse than average.

[-] Wahots@pawb.social 3 points 9 months ago

While true, it's way better better for a power source to be inefficient than all consumers using inefficient/dirty appliances.

Once the aging coal plant is decommissioned in favor of a new nuclear reactor in a state like Wyoming, anyone using stuff like electric water heaters, heatpumps or electric bikes/buses/cars/scooters is instantly using 100% renewable power.

Even in screwed up states like Texas, there is so much load on the grid (and the fact they cannot buy power from other states) means that cheap solar panels, battery storage and wind are way faster to put up than expensive methane/natural gas generators.

[-] Pulptastic@midwest.social 2 points 9 months ago

I don’t consider nuclear as renewable, but they do reduce CO2 production.

I've been wondering... Those batteries are really heavy and I've already had to explain to multiple customers that their ~1000kg heavier and ~100kw stronger engine (to get similar acceleration in a comparable model to the gas vehicle) is going to eat up tires twice as fast. If you were burning through a set of tires a year you better budget for two sets and the extra time to come in and have them changed every 6 months. And all those extra tires have to come from something. And shipped from somewhere. And then the roads need repaving more often because of both the extra weight and higher power output. 1000's of km of road that will have repaving works going on twice as often. On top of reduced traffic throughput while roadworks are ongoing, is any of that taken into account when comparing environmental impact? How will the increase in airborne particles and toxic runoff from the roads affect the environment?

[-] LifeInMultipleChoice@lemmy.world 3 points 9 months ago* (last edited 9 months ago)

The vehicles weight a little more, but the move to solid state batteries will decrease weight by 30-50%. So that issue is already being addressed. Batteries will get better as we start to use them as competitive markets drive fixing such. We aren't improving gas powered vehicles much anymore, they still kill people with their exhaust daily. Anyone going against the movement is for killing people and the environment. Dead stop.

IMO, I still think there's not enough infrastructure to support charging EVs. Don't get me wrong I've seen some. Just... Not a lot. Until charging is as prevalent as gas its just not worth it. Or if you have a house I guess.

In some areas I hear it's good. But in my area there's only 1 set of charging stations at a Wawa that I know of. And that Wawa is an hour drive away. Plus I'm at a rental complex that mows the lawns regularly and having a cable run from my house to the car is not allowed.

My current gas operated vehicle has about 160000 miles on it. I'm hopeful that my vehicle will last a long time. And then when my vehicle dies, I'll look at the infrastructure again and see if it's beneficial for me to switch to an EV. I'm going to continue to wait until it's beneficial for me to buy a new car.

We'll see how it goes.
