Put them in a sealed room with a gas engine running and you'll see how fast they realize that they're cleaner
Isn't the whole point that the gas engine equivalent is just in somebody else's room though?
In any case, I'll take whatever partial climate wins we can get.
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?
Solar, wind, and nuclear energy: are we a joke to you?
Fair, but the first rebuttal is going to be "go into a sealed room with a coal fire burning"
I'd happily hang out in a sealed room with a nuclear reactor.
... how is that an argument?
The argument is that all you're doing is moving the carbon emissions from the car directly in your vicinity to the coal-fired power plant a long distance away. Move that same coal-fired power plant into the sealed room, and suddenly it's no longer far away, and the "unclean" nature of the electric car, so the thought process goes, becomes obvious.
That's the thought process if you just stop thinking when you get to a point that reaffirms one's biases. If you continue down that train of thought you'd realize it's a lot easier to regulate and monitor the emissions of a coal power plant than it is every single car on the road. Plus you don't need to use coal to make electricity.
