I have seen breakdowns of how much energy it takes to charge a typical EV and that in order to produce that energy it requires about 40 lbs of coal. Lots of variables of course but in the end it's certainly not a "Net Zero" and in most cases the EV has a larger footprint than a fuel efficient vehicle with similar capabilities.

Old video, but examples like this abound.

Here's a Belgian EV police car charging off a diesel generator.



It's sort of like asking other countries to drill for oil instead of doing so here. Pushing the "pollution" somewhere else somehow makes it OK. Out of sight, out of mind I guess.

Would love Nukes! It's literally the best for the environment but liberals don't want to subsidize it and then say "well no one wants to invest in it!!" Yea no ***** How about subsidize nukes instead of wind you idiots!

Was the lithium for the batteries also sourced in a sustainable way, or did it come from strip mining?

The efficiency of a power plant turning fossil fuels into electricity is roughly the same as an ICE vehicle turning fossil fuels into mechanical energy, vehicles vary but they are essentially the same from source to the wheels. The efficiency of an EV comes in turning kinetic energy into electricity via regenerative braking. Slowing down by generating electricity instead of generating heat through the brakes is the difference. You get this with hybrids as well, which is why the exact same vehicle with a hybrid vs an ICE gets better gas mileage. It is 100% due to regenerative braking.

Don't know and don't care. I'm not an environmentalist. I'm not giving up my car, power tools, phone, or any of the other numerous items I have powered by lithium batteries.

Then why would it matter your car is charged by nuclear? Who cares where the electricity comes from.

I don't think most green energy advocates understand that hydrocarbon energy was actually a result of sunshine, plus geologic pressure, plus time. We are capturing solar energy that has been sitting idle in the lithosphere for the past few million years.

The point isn't clean energy and the point certainly isn't fast (but boring IMO) EVs. Those are just the carrot on the stick. They want everybody driving a boring appliance that will be government controlled and worth nothing more than recycling after a decade or so of use. EVs might have quick 0-60 times now, but that won't last long after a few idiots launch themselves into concert venues in cars that accelerate way too fast for the average driver on the street. They'll be limited at first to certain discharge rates (you know for the environment), to limit their acceleration and top speed. Then they'll be monitored by government entities. Eventually they'll be self driven within the constraints set by daddy sugar.

Motorsports and fun to drive vehicles will be all but dead unless you are wealthy enough to own and maintain expensive dedicated track only vehicles. They'll try to ban ICE engines in those, off road and on water vehicles some time during this timeframe.

We're already seeing rhetoric condemning the high energy usage of the new Hummer EV. It's going to happen. You'll ride in your government authorized and extremely overpriced/over regulated self driving appliance and like it.

Also, China processes most of the lithium ore, using electricity generate mostly from coal.

K. The amount of energy from braking varies widely though based on usage. If you are commuting in heavy traffic it helps. If you are making a road trip it makes almost no difference. The braking also just helps on the margins in terms of energy production, it's not like you can go twice as long because you are braking. The efficiency can also be easily used up if you are using other electricity in the car for functions beyond driving (AC, Radio, etc).

The larger point though is that you have to charge the car in order to use it at some point and when you charge it you are probably burning a large amount of coal or natural gas in order to do so. I won't even get into how terrible the process is to get the materials to create the batteries.

You need to insert the loss of energy in the transmission of the electricity from the plant to the destination. Also the loss (due primarily to heat) in the charging process.

When you factor in the later then you are losing energy. The braking makes up for it, however the charge/discharge cycles most likely has the greatest impact on energy loss.

Because nuclear energy is the most powerful and efficient source of power we have. We need more of it. Nextgen reactors are meltdown proof and if we cut the regulatory and nimby issues it could be extremely cheap. Utilize breeder reactors and it's a virtually limitless source of power.

Mary Barra was largely unqualified, and was a big Dem-CCP donor so that is why Obama put her in charge of GM after using $11 Billion taxpayer money to screw shareholders and save the unions.

But, she then led the way in laying off many thousands, wasting money on the volt until it was killed, then put terrible people in charge of the Spark/other electric projects that cost literally billions (and outsourced more of their battery stuff to LG/asian interests), and Biden of course loves her.

Quote:

Throughout the 2012 presidential election cycle, Biden routinely claimed that "General Motors is alive" following the Obama administration's $11 billion taxpayer bailout of the company in 2009.
Years after the bailout, Biden and officials with the Obama administration not only touted Barra's leadership at GM but invited her to the State of the Union Address in 2014 and took photo-ops with the executive.

Today, Barra is overseeing the layoff of thousands of American workers as GM shifts and increases production in Mexico and China. Barra's mass layoff effort is stopping production at four of its U.S. plants, including Detroit-Hamtramck and Warren Transmission in Michigan, Lordstown Assembly in Ohio, and Baltimore Operations in Maryland.

While GM was bailed out by U.S. taxpayers, the Obama-Biden scheme came with no commitments for the corporation to stop outsourcing Americans' jobs overseas.

In 2011, Hoover Institution at Stanford University research fellow Paul Gregory noted that despite the Obama-Biden bailout for GM, the company continued outsourcing American jobs abroad. A 2011 report detailed GM had less than 75,000 jobs left in the U.S. while employing more than 122,000 foreign workers overseas. At the time, nearly two-thirds of GM's workforce was located abroad.

Rather than stopping GM's outsourcing, the Obama-Biden scheme focused much of their attention on subsidizing and promoting electric, plug-in cars like the Chevy Volt. Last year, Barra announced that production for the Volt, as well as the Chevy Cruze, would end.
Quote:

While GM lays off thousands of American workers this year, its production in Mexico and China is ramping up. Specifically, GM is looking to manufacture an electric Cadillac in China and continue manufacturing its Envision compact vehicle in China.

The made-in-Mexico Chevrolet Blazer will soon arrive in U.S. markets. Last year, GM became the largest automaker in Mexico as it has cut jobs in America and increased production in Mexico.

Offshoring production to Mexico has proven cheaper for GM executives because American workers earn about $30 an hour while Mexican workers earn about $3 an hour, a 90 percent cut to wages that widens the corporation's profit margins. Meanwhile, Barra continues to earn a salary of about $22 million.
Yet again, the CCP-Dem party hates American industry, period, and is an enemy to American workers/ingenuity. She really is/was the Joe Biden of the auto industry; played a clueless role, leading a demise.

On top of the whole coal thing...We literally destroy large chunks of the earth and many pristine environments to mine the minerals for these batteries. It takes TONS of the earth's crust to mine for A SINGLE EV BATTERY. Yet you are noble and conscientious if you drive an EV and a backwards mouth breathing ******* if you consume fossil fuels. Liberals are so f-ing stupid.

I'm aware and don't disagree. It's helpful if you understand the facts a bit better though. Just as an example of how much energy is recovered through regenerative braking, our old Sienna minivan got 18-19 mpg, our new one with a hybrid gets 35-36mpg. That difference is almost entirely the recovery from regenerative braking. The real loss of highways driving is that once you get to high speeds most energy is lost to wind resistance. EVs make almost no sense to me on roadtrips. I have no desire to extend the trip time by 25% sitting at a charger waiting to "fill up"

The conversion of fossil fuels into the wheels turning is roughly the same whether it be a power plant that charges an EV or an ICE engine, but don't discount the other factors at play. For myself I will always own a vehicle that runs on gas, but I can see the usefulness of having an EV for local driving, and I'll probably get one at some point once the price comes down. I don't care about the source of the electricity, just about the cost savings.

Even if all electric vehicles are powered by coal and natural gas plants, it's still twice as efficient as gas-powered engines.

Can you show me evidence of this? I'm genuinely curious. I have wondered if they are more "carbon efficient" or whatever the unit of measurement would be for comparison.

Compare that to the energy used by a tanker truck to deliver fuel to a gas station.

I agree with all of this, but why virtue signal you drive an electric car powered by nuclear in this thread? No one cares. It's a thread making fun of a dumb virtue signaling CEO.

Edit: you know what Salute the Vaccine, never mind. I don't need to talk to you anymore. Just realized who you were before the name change. Explains why you found a new cause to virtue signal about.
