How "green" are electric cars?

America's electricity is still largely coal-fired, with natural gas being a close second and nuclear a distant third.

The U.S. is second only to China, which is about twice as reliant on coal, in annual carbon dioxide emissions.

A report which analyzes the life cycle of car emissions (ie, all the way from those created by the mining of materials for batteries, via the ones from the production of fuel and the generation of electricity, to the muck that actually comes out of the exhaust) finds that a battery-powered car recharged with electricity generated by coal-fired power stations is likely to cause more than three times as many deaths from pollution as a conventional petrol-driven vehicle.

Even a battery car running on the average mix of electrical power generated in America is much more hazardous than the conventional alternative.

Electric cars whose batteries were topped up from wind, solar or hydroelectric sources came out cleanest, causing 231 putative deaths over the course of a year, compared with 878 for petrol cars.

Electric cars recharged with power from natural-gas-fired stations were also a lot less lethal than petrol-driven ones, with 439 deaths. But if those same electric cars were recharged ultimately by coal, they would be responsible, according to the model, for just over 3,000 deaths.

What's funny? :dunno:

Research shows that electric cars are cleaner than those that rely on internal-combustion engines only if the power used to charge them is also clean.

Child please
 
Hey feel free to gobble exxons nuts
I'm not even a warmer
I drive electric cause it's like an iPhone vs a rotary phone
The smug factor over Dino deniers is just a bonus
I get 100 mpge with zero emissions
You gotta be sucking some denier jizz to think its not cleaner

It is, if the power used to recharge the EV is clean.

Unfortunately, most power plants in the USA are not very green.

Electric motors are exponentially more effient
I have yet to see a non biased article saying gas engines are cleaner.
I've seen dozens of clean car list, and electrics are always on top

I'm not disagreeing with you.

The EVs are wonderful. It's the electricity that is generated by dirty coal in many cases that is the issue.
 
I'll add this for those wanting education, as I feel you are trolling.
Emissions from power plants are often out in the countryside not adding to city smog.
Also the grid is getting cleaner ever year
Many ev drivers also use solar panels which make them zero emissions.
Don't feel so guilty driving outdated gas technology
