Yet another study finds that “whole of life” carbon footprint of electric cars is little different to conventional cars:
April 14th 2021, Jefferies published a research note entitled “Are EVs as ‘Green’ as They Appear?” in which they conclude an electric vehicle must be driven 200,000 km (or 124,000 miles) before its “whole of life” carbon emissions equals that of an internal combustion engine.
Their analysis is very similar to ours and details the tremendous amount of energy (and by extension CO2) needed to manufacture a lithium-ion battery. Moreover, they point out that a typical EV is on average 50% heavier than a similar internal combustion engine, requiring more steel and aluminium in the frame. They conclude the “embedded carbon” in an EV (i.e., when it rolls off the lot) is therefore 20–50% more than an internal combustion engine.
Our analysis suggests a modern lithium-ion battery has approximately 135,000 miles of range before it degrades to the point of becoming unusable. An extended-range Tesla Model 3 has an 82 kWh battery and consumes approximately 29 kWh per 100 miles. Assuming each charge cycle has a ~95% round-trip efficiency and a battery can achieve 500 cycles before starting to degrade, we conclude a Model 3 can drive 134,310 miles before dramatically losing range. Incidentally, Tesla’s Model 3 warranty covers the battery for the lesser of eight years or 120,000 miles and does not apply until the battery has degraded by at least 30%. If the Jefferies analysis is correct (and we believe it is), then an EV will reach carbon-emission parity with an internal-combustion vehicle just as its battery requires replacement. This will come as a huge disappointment for those believing that EV adoption will have significant impacts on CO2 reduction.

“Are EVs as ‘Green’ as They Appear”
Lol, why thank you!
They are just green enough to convince a bunch of gullible idiots to invest a ton of money in them and their associated infrastructure which they then declare to be actually bad for the environment and demand that it all be torn out. It is all a ruse to waste time and money.
Those of us who actually know engineering pretty much had this sussed out a few years back.
The same people who believe the answer is “yes” are the ones who would both believe that climate science is “settled” and that anything which conflicts with their core beliefs is “misinformation”.
Three reasons consumers will not buy EVs: 1) Limited range 2) No all weather reliability 3) Enviormental disasters
Remember when the greenie leftists forced oil companies to add MTBE to gasoline? Then they discovered how dangerous it is and insisted oil companies remove it. Somehow they then managed to lay the blame on oil companies for using it in the first place.
Nobody wants to talk about how to dispose of all the spent batteries in a few years. Even now, there is a real problem with what to do with worn out solar panels. Environmental nuts are ruining this country, but that is their goal.
I don’t really care how “green” they are. Mine is cheaper to operate than a gas car.
A kilowatt is 25 cents and gets me 4 miles. That is 16 miles to the dollar, and gas is 4 dollars. Gas takes my wife’s car 32 miles for 4 dollars, my electric gets me 64 miles for a dollar. Even the expensive recharge options get me 48 miles for 4 dollars.
Maintenance is pretty much rotating the tires and adding windshield washer fuel. Brakes last longer because of regenerative braking. You can’t get an oil change, even if you want one. I replaced two tires because I ran over screws driving behind Home Depot. Never drive behind Home Depot.
As far as the lithium battery is concerned, I feel a little bad about that. Mine has a lifetime warranty, and also a recall to have the battery replaced outright. I have just over 20,000 miles on it and I will have a brand new 64 kilowatt battery probably before 25,000 miles.
Green, schmeen. I love the peppy response and quick acceleration. I mostly loved the financial incentives like 2500 from California, 7500 from the Federal Government, and 600 from my local utility.
“Nobody wants to talk about how to dispose of all the spent batteries in a few years.”
That is because they are recycled!
Don’t forget the environmental impact of worn out wind turbines.
Not to mention thousands of old wind turbine blades.
“A kilowatt is 25 cents”
My kilowatt is 12.5 cents. Less on night rates.
Would you have bought it without someone else paying for a large part of it?
Nothing we do to “reduce emissions” will have the slightest effect on the “climate”,
since China and India are operating many hundreds of coal-fired power plants and are going to build many more. “Climate” is world-wide.
“Our analysis suggests a modern lithium-ion battery has approximately 135,000 miles of range before it degrades to the point of becoming unusable.”\
According to a survey conducted by the organization Plug In America, the battery pack in the Tesla Model S only loses about 5 percent of its capacity over the first 50,000 miles on the road, on average, and that rate slows down as additional miles are put on the odometer. Tesla reports that in its own controlled testing, the Model S batteries retained 80 percent of their range after running for a simulated 500,000 miles.
The best part of that was when they were forced to add MTBE they had to raise the price, then when they took it out, well then, they had to raise the price to get rid of it.
Odd that the article doesn’t mention the fuel used to generate the electricity to charge the cars. The the end of the article, there is this little PS: “To read more on this subject, including a section on photovoltaic solar power, we encourage you to download the full commentary, available below.”
This seems to suggest that the cars will be charged using solar-generated electricity. But that is a whole ‘nother can of worms as it only works during the daytime without clouds. You need HUGE batteries to store solar at night and today’s entire battery storage infrastructure in the USA would power the grid for less than a minute.
The energy usage in producing *green energy* products is incredible.
