EVs are cleaner than gas cars, but a growing share of Americans don't believe it (www.wcbu.org)

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 wide range of organizations have confirmed that EVs still beat gas.

Even if we assume all the electricity is coming from carbon sources (there's no need for any of it to be carbon sources) it's still more efficient because power plants are way better at turning that chemical energy into electricity. Even with the losses in the lines, charging, and in your motors, electric cars are still significantly more efficient on a mile per kg CO2 basis than gas cars. Throw some solar panels on your roof and they become essentially carbonless.

It's really easy to understand why too. You completely waste most of the heat energy you produce in IC engines. They're incredibly inefficient and always will be.

Yeah, what is it, 70% energy lost to heat in an ICE?
