The answer is 'It still depends...'

Can't read the full article because it's behind a paywall, but an important aspect to also keep in mind in these types of analysis is how dynamic the answer to the question is-- not only does the grid typically get cleaner over time (making the EV operation cleaner than its ICE cousin over time), but the greater penetration of EVs helps the market in creating more EV charging infrastructure, utility EV programs, and the like. So when people drive EVs, they can be a small part of the change that's making it easier and more affordable for future EV drivers as well

Argonne once offered a free GREET Workshop, where anyone could stay at the lab in an opulent guest facility for $75/night while listening to lectures and instruction during the day.

The analysis by Reuters is mostly right, but here they get it wrong:

"Even in the worst case scenario where an EV is charged only from a coal-fired grid, it would generate an extra 4.1 million grams of carbon a year while a comparable gasoline car would produce over 4.6 million grams, the Reuters analysis showed."

According to the GREET model an EV charged by a 100% coal-fired mix emits 370g GHGs/mi; a comparable SIDI* gasoline-powered car emits only 353g. This is pure gasoline BTW - not the 5.7% ethanol blend used in California and many other states, where gasoline emissions would have been even lower:

True, if you were buying a car in the 1980s without fuel injectors, you would have been better off with an EV. But in the 1980s EVs didn't exist.
