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.

“EV’s” largely appeal to people who #F___ingLoveScience. They only need propaganda.
” I mostly loved the financial incentives like 2500 from California, 7500 from the Federal Government, and 600 from my local utility”.
Isn’t socialism grand?
I believe it has been said that conversion to pure EVs will require the electric grid to be increased in captivity some 7 fold ove4 what it is at present. That simply will not be allowed by the Watermelon Environmentalist.
EVs are a boondoggle, snake oil potables.
Hybrids make sense. They carry their generators with them and so naturally and effortlessly scale to demand where the grid does not.
EVs do not make sense.
Money doesn't grow on trees.
Wouldn’t it be in Tesla’s interest to maybe fudge the numbers a tad....aka Volkswagen a couple years back and the fudged safety tests of Volvo?
You also paid up front far more for an EV car, so there is that to consider. Not to mention, States and congress are looking at taxing EV vehicles since they do not pay gas tax.
“Those of us who actually know engineering pretty much had this sussed out a few years back.”
This was actually settled in the early 20’s.
How are they recycled? Into what?
There is no good way to dispose of the solar panels or the wind blades. Landfills for both.
Yes they can be recycled by dropping them in a live volcano, now that is recycling.

Owners survey
It might enhance your credibility if you learn the difference between “kilowatts” and “kilowatt-hours”.
“Shuttle service Tesloop announced their first Model 3 fleet vehicle crossed 200,000 miles and lost only 6% of its original range. Since then it crossed the 300,000 mile marker and it’s still going strong.”

“Most batteries that Tesla recycles today are pre-consumer, coming to us through R&D and quality control. None of our scrapped lithium-ion batteries go to landfilling, and 100% are recycled. The small amount of post-consumer batteries that we receive are generated from our fleet of vehicles on the road, predominantly from taxi-like vehicles. Since we have only been producing Model S for approximately eight years, it will likely be some time before we start receiving back vehicle batteries in larger volumes.
All materials contained in a battery remain in their original form at end-of-life and the vast majority of these materials are then captured in the recycling process. Presently, only high-value elements are recycled and re-introduced into the supply chain.
However, as recycling technology improves, we strive to re-introduce more and more materials back into their original commodity markets. Over half of the materials in a battery cell are metals, which is great for sustainability given they are infinitely recyclable. The remaining materials are plastics, organics, and other difficult to re-use materials.”
Hyundai offers lifetime battery warranty on new EV.
Tesla so aiming for one million miles.
They don’t ever appear green to anyone with an IQ over 80 ie nonDemocrats.

Do you have any data to refute my posting?
A big reason will be they take too long to “fill up”!
If we have to wait a good while to charge up a car, why not just use steam?
Nope. Just asking a question based on prior experience with these rosy projections.
EVs are OK if you live south of the 41st parallel. The farther north you go, the less useful they are.

Ample can restore you to full capacity in 10 minutes.
Unless you drive hundreds of miles a day, you can charge while you sleep.
