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.

“Nope. Just asking a question based on prior experience with these rosy projections.”
Info was past data; no projections.
What is “Ample”?
And what is its platform?
Will you be able to get easy charges on a real trip? Will you be able to carry multiple people and much luggage?
And what if all these corps and gives stop catering to you for free charges in their parking lots?
Corps and govs
Yeah but the awesomeness the EV owners FEEL and sense of superiority over Neanderthal “IC” car owners far outweighs the CO2 issue. And it makes them less racis’ too. 😲😂🙌👏💰💰💰
Jeff Dahn, Canadian Battery Research Institute says we are closed to two-million mile battery.
If cycling is mostly between 25-80% there is almost no degradation. It would be feasible to put used modules in ew cars.
Yes, yes

I remember when diesel was so cheap, people were putting up with electric blankets on their engines in New England at night to save on fuel costs. The fuel industry cracked the code and eliminated the wasteful production of diesel. Now, the savings is gone.
The give-always, free electricity at work, missing taxes, etc. that EVs enjoy will be gone, too, at some point. It sounds like it works for you now, with a lot of freebies and $4 / gallon gasoline, but the freebies are counter to a free market and $4 gasoline is too much, anyway, so I’m not too convinced.
I see a lot of advantage in getting a horse though, too, so take it for what it’s worth.
give-always = give-aways
What kind of car do you have?
I bought a 2017 BMWi3, and I love that thing.
Acceleration, 0 to 60 in about 5 seconds.
All the maintenance of an engine, gone.
I’m an old car mechanic and I could care less about global warming. Global warming is a crock. These things rock. I love driving by the gas station and waving!
I have a solution for spent solar panels.
Escort some B52’s over Iran and have the air force drop them on Iran from 10,000 feet.
If thats not good, drop them into a volcano in Hawaii. Recycled in a few seconds.
There’s an idiot driving around Allen, TX in a Tesla with vanity plates that read “IMGREEN”
I have to laugh out loud at him every time i see that car.
Problem: “how to dispose of all the spent batteries.”
Observation of problem: Toyota mechanics at my local shop have a stack of Prius batteries in the back of the shop, since the mechanics don’t know what to do with them and conclude they are toxic.
Solution: plasma recyclers. They recycle everything, including spent uranium fuel and car batteries.
Tgey suck ass. Screw electric cars
What was it that the Top Gear UK crew said? That one SUV will emit far fewer greenhouse gases over its lifetime than what is emitted by the mining of enough lithium for ONE Prius - and that’s not even 100% electric.
I would believe that. Lithium mining is FILTHY.
With all of this rip off of our money to the pagan god of Climate Change, let’s do a little math:
The total mass of Earth’s atmosphere is about 5.5 quadrillion tons.
Man has produced how many tons of CO2 over the industrial age and what percent of the earth’s atmospheric tonnage does that amount to?
This may be too conservative. However, we have produced only 0.00022% of ALL CO2 in the atmosphere- that’s it- and since natural CO2 is just .004% of the atmosphere- that means we’re only responsible for such a SMALL % of the total atmosphere that it’s not even significant in the slightest- there is simply NO way man can be responsible for global climate change- none!
‘Scientists’ should be ASHAMED of themselves for even suggesting man is responsible!
Our atmosphere is comprised of 6 quadrillion tons of molecules- 6 quadrillion folks! ALL natural and man made CO2 amounts to just 8 billion tons- That is NOTHING compared to the sheer volume of atmosphere- it practically doesn’t even register- it is such a small portion of our atmosphere that there is absolutely NO way such a small amount can capture near enough heat to raise our earths temps one iota- period!
Man-made carbon dioxide emissions throughout human history constitute less than 0.00022 percent of the total naturally emitted from the mantle of the earth during geological history.
Earth’s climates change all the time. CO2 spikes all the time. To try to blame climate change on 0.00022% of the atmosphere is ludicrous regardless of how old you might think the earth is. The fact remains the total amount of CO2 produced by man for the whole of the industrial age is just 0.00022% in relation to the total tonnage of atmosphere. How can 0.00022% of the atmosphere cause global climate change? How can just 0.00022% of our atmosphere capture enough escaping heat, then radiate a FRACTION of that heat back to earth to cause climate temps to rise? Note: I’m being generous because not all of the 0.00022% over the industrial age is still in the atmosphere.
Right now the CO2 levels are 415 parts per million. 415 parts per million is .0415% of the atmosphere. In other words, the atmosphere is 99.96% NOT carbon dioxide. Water vapor is a much more plentiful greenhouse gas. The problem is, the Leftnicks can’t spin a narrative about evil oil companies producing water vapor.
Actually, it's more than just 'a few years'. With a single sheet of paper and a pencil, it can be easily shown that "green EVs" are simply impossible. The insurmountable problems include, but aren't limited to, raw materials, manufacturing processes, electricity generation and distribution, toxic waste, range, safety, and more. EVs (sort of) work. (That's as long as you don't have to go very far, have lots of time to recharge, and get their electricity from Unicorn farts). "Green EVs" are simply a pipe dream.
And yes, I'm an engineer, an automotive engineer. I have been for more than a half century. I first considered building an EV when I had a college roommate who did just that. He built an EV with a VW Bug, a few Die Hard batteries, and an electric motor, back in the '60s. It didn't work very well, and nearly killed him. I did the math then, and concluded that even with a free mid-day charge at work, it was too expensive to build and use, and had too little range for even my 11 mile commute. I participated in the design of the GM EV back in the '90s, as well. Rare Earth components, Li-on batteries, better control systems, and vehicle technology have significantly improved in this time period, but they're simply not enough.
Any plan that requires inventing new things within a certain time, is doomed to fail. I know that, too. My latest patent is for a device I first thought about some several decades ago.
Working from home, instead of commuting every day, has done far more to reduce my automotive carbon emissions.
I received an email telling me that my Mach E has just been built.
“ EVs do not make sense.”
EV’s can make sense if you use the tool for the right purpose. Just as a butter knife makes a bad screwdriver, ICE cars aren’t really good at short daily commutes. They get lousy mileage and it’s hard on the engine. EV’s are better for those short daily trips.
EV’s suck as a long distance trip vehicle. They only make sense to own if the EV is not your only car.
