With 44% of the US electricity coming from petroleum or coal does an EV in the US make sense if the goal is a reduction of green house gases?
This sounds like fairly typical recurring FUD (Fear, Uncertainty, Doubt) that is dredged up about EVs every 6 months or so.

*Of course* IF you compare the latest and lowest emission gas engine to one of the oldest coal plants in Tennessee (or some-such) many environmental factors are a draw, and some go one way or the other. Especially if you hand pick an electric vehicle and use it as counter to it's design as possible, all highway miles, for example, to use the most electricity as inefficiently as possible.

*Of course* this is leaving out that people aren't buying EVs to drive 100 highway miles each way in Tennessee.

They are using them *in cities*, where the regen greatly heightens mileage, and that is mostly *in states* which due to population density and pollution concerns have long been very tough on electric generation emissions, such as California. And this will improve even more over time as old plants are retired and replaced with new highly efficient Natural Gas based plants or even greener alternatives.

Under those much more reasonable circumstances EVs can look very good. Though I do still have concerns about the battery and electric motor materials, where they have to come from, the damage done by their extraction and use... (then again, the alternative is the middle-east...)

But I don't need some probably petro-chemical funded "study" from some *Norwegian* university to tell me this!

Next can we have a petro-chemical funded red-herring article about how electric is a dead end, that Hydrogen is the magic beans and is just 5-10 years away (same as the last 20-30 years...)? Make sure it mentions that Hydrogen *can* be broken out of water but entirely skips over the fact that the only economical way to make it... is to break it out of petro-chemicals!
