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.aggie93 said:
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.

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

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.
Also, China processes most of the lithium ore, using electricity generate mostly from coal.aggiebq03+ said:Teslag said:

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).kb2001 said: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.

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.kb2001 said: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.

Then why would it matter your car is charged by nuclear? Who cares where the electricity comes from.
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.Pookers said:
Women CEO's of car companies. Might as well put a man in charge of tampax.
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.
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.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.
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"aggie93 said:K.

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.

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.

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.
