It actually depends a lot on where you live - that electricity has to come from somewhere, and in much of the country, that means most of what you use to charge your electric car's battery came from coal, gas, or both.
If it's nat gas that should be bunches cleaner and more efficient than ICE.
As far as coal, it's dead...just will take a few more years to be irrelevant.
"39% of the country's electricity production at utility-scale facilities in 2014, 33% in 2015, 30.4% in 2016 and 27.4% in 2018"
Follow that trend another decade and what will you have? 12% decrease in 4 years....so in 12 years it would be 36% lower...or NEGATIVE. In reality it will be less than 10% or effectively meaningless (not needed, just some companies using up their capital equipment).
You'd have to do some fancy calcs to work out the ICE comparisons...the cost of making the thousands of parts in an ICE drive train and then maintaining them is big time. But a very basic efficiency deal might work out like this....
100 units of nat gas energy at the input of an electric plant - 62 units out (efficiency loses).
8% loss in transmission of that 62 units = 57 units delivered to your electric car
Electric Car is 80% efficient - so you get 45 approx units of motion for your original 100.
Compared to:
100 units of gasoline energy - 85 units delivered to the pipeline (15% refining losses).
85 units minus another 5% for trucking, storage, evaporation and leakage - 81 units.
Efficiency of ICE complete system (20%) - means you get 16 or 17 Units of energy.
Which is better? Turning in your dollar for 45 cents? Or turning it in for 16 cents? You decide.
This does not figure in the vastly increased pollution from the Oil and gas and all that stuff.....
Think about it.
Note - a top-notch hybrid driven perfectly will fall in-between the two...perhaps 25 or 30 units for your 100. A lousy hybrid much less.
Any engineer could have told you this was the case.
Obviously not the 10's of thousands of actual Engineers working on hybrid and electric cars and such....
I'm sure the same engineers doubted that Musk could have built rockets and won Air Force contracts...and do it for 1/4 or less the price of the big guys.
Heck, Bill Gates said no one would ever be able to use more than 640K of RAM.
Obviously, Waldo knows a lot more than the largest car company in the world - VW - which is going to make massive investments in electric cars.
Waldo, you could make big bucks by consulting with them and saving them money!!
"Kacher says the powertrain and electronic controls systems of the Model 3 really knocked the socks off the German engineers. He reports they were astonished by how “compact, expandable, fully integrated, modular, easily accessible, well protected, low priced, and astonishingly clever” the Model 3 is in so many ways."
Ah, but what do these BMW engineers and executives know? Waldo knows much more...

How silly and prime example of the obtuse arguments given for such a simple premise. They weren't hired to produce a car that runs on batteries. I can guarantee you there are absolutely no engineering documents that say make a "green" vehicle. That's a political & religious statement, not an engineering specification.
Top German Auto Engineers Tear Down Tesla 3 and say their companies can't currently compete or make anything near as good.....

I know how to read an article to discover fluff vs fact.
They said not one thing about the actual engineering of the vehicle beyond the fact they have managed to rook buyers into a single touch screen instead of a real automobile dashboard.
And automobile experts who HAVE torn down the model 3 and looked at it are astonished at the over engineering that makes it almost impossible to build reliably on a consistent basis. Too many parts. Model 3s are plagued with endless quality problems out of the factory. Atrocious when you find the average cost for one of these things is ~$65,000.
Eighteen percent of all electricity in the United States was produced by renewable sources in 2017, including solar, wind, and hydroelectric dams. That’s up from 15% in 2016, while the Trump administration has signaled a desire to cut funding for renewable energy and efficiency programs, the trends seem set to continue thanks to market forces.
The Renewable Electricity Futures Study found that an 80 percent renewables future is feasible with currently available technologies, including wind turbines, solar photovoltaics, concentrating solar power, biopower, geothermal, and hydropower.
