...EV's are greener than fossil fuel powered cars, even when the power comes from coal...
I know your really believe that statement and many people talk as if it is true. But when unbiased science is applied, it ain't so.
From A NASDAQ analysis titled, "ANALYSIS-When do electric vehicles become cleaner than gasoline cars?"
...It was up against a gasoline-fueled Toyota Corolla weighing 2,955 pounds with a fuel efficiency of 33 miles per gallon. It was assumed both vehicles would travel 173,151 miles during their lifetimes.
But if the same Tesla was being driven in Norway, which generates almost all its electricity from renewable hydropower, the break-even point would come after just 8,400 miles.
If the electricity to recharge the EV comes entirely from coal, which generates the majority of the power in countries such as China and Poland, you would have to drive 78,700 miles to reach carbon parity with the Corolla, according to the Reuters analysis of data generated by Argonne's model....

Don't pretend you'd accept peer reviewed research when you'll just dismiss it with "Be advised that Universities routinely compete for Gov’t Grant moola ($$ cash cow) by willingly contracting to substantiate what’s often and essential a politically preordained outcome"
Where's your peer reviewed research backing your claims? - 3_tonsExplorer IIIAt best, a Forbes Opinion writer (or any other cherry picked ‘green theologian’) merely offers his anecdotal account repeat with bias (opinion is bias) in no way a substitute for objective empirical independent study…Before adopting such policies, where’s the independent peer reviewed study??

EV's are greener than fossil fuel powered cars, even when the power comes from coal
But as the nation shifts to renewable energy, electrical powered transportation becomes greener during that shift. In my state, over half of our power comes from renewables.
Electric locomotives also gain efficiency for the same reason that EV's and Hybrids do -- they can use regenerative braking and send power that would otherwise be wasted back into the grid. - Timmo_Explorer IIOh, I don't discount the leverage magic that gears/winches/differentials/transmissions provide...just pointing that electric motors are preferred over ICE in certain commercial applications (including trains).
And yes, the outrageous power density required for the battery packs to power locomotive electric motors is a giant challenge. And then the hurdle of obtaining sufficient power generation abilities from hydro/solar/wind sources to charge said batteries. And don't get me going about how wrong Thacker Pass open mining operations for lithium is for the environment and the area's indigenous peoples.
All in the name of "climate change".....(shakes head). - 3_tonsExplorer IIILOL :) Just because you don’t SEE the fuel tanks doesn’t mean they don’t exist elsewhere (outta sight, outta mind!) - and therein lies the grand EV gimmickry…

If we look under the hood of a train's locomotive we will see a large diesel engine that powers an electric generator that supplies electricity to powerful electric electric motors known as "traction motors".
So this should diffuse any suggestion that electric motors lack torque or power.
True, but if you look a bit lower at the locomotives chassis you’ll also find several HUGE fuel tanks full of diesel…Critical thinking sometimes Required…
Sometimes a different perspective is required... Can you point to the fuel tanks on this freight train? - LynnmorExplorer

That system is used in place of enormous transmissions and clutches.
And your point is?
Read it again, maybe you didn't catch the reason for that type of transmission. Those "powerful" electric motors are there to transmit power developed elsewhere, just like those in any electric vehicle. - 3_tonsExplorer III
