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.
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’m skeptical that hybrids with ICEs and transmissions at their heart really do have more longevity than BEVs and electric motors. ICE and especially hybrids are inherently more complex than BEVs, and have many more moving mechanical parts to wear out over time. So while BEVs may technically be “harder to repair”, there’s actually much less to repair in the first place. not to mention less maintenance like dozens of oil changes over the life of the car.
I’d like to see a source that says hybrids, with two separate engines plus the mechanical linkages between them plus the transmission, have better repair scores than a pure EV with no transmission, no mechanical engine, and a simpler drivetrain.
