Green energy
Batteries: do not make electricity – they store electricity produced elsewhere, primarily by coal, uranium, natural gas-powered plants, or diesel-fueled generators. So, to say an EV is a zero-emission vehicle is obviously not valid.
Also, since forty percent of the electricity generated in the U.S. is from coal-fired plants, it follows that forty percent of the EVs on the road are coal-powered! Get it?
Einstein's formula, E=MC2, tells us it takes the same amount of energy to move a five-thousand-pound gasoline-driven automobile a mile as it does an electric one. The only question again is what produces the power? To reiterate, it does not come from the battery; the battery is only the storage device, like a gas tank in a car.
Please note all batteries contain toxic, heavy metals.
But that is not half of it. For those of you excited about electric cars and a green revolution, I want you to take a closer look at batteries and also windmills and solar panels. These three technologies share what we call environmentally destructive production costs.
A typical EV battery weighs one thousand pounds, about the size of a travel trunk. It contains twenty-five pounds of lithium, sixty pounds of nickel, 44 pounds of manganese, 30 pounds cobalt, 200 pounds of copper, and 400 pounds of aluminum, steel, and plastic. Inside are over 6,000 individual lithium-ion cells.
It should concern you that all those toxic components come from mining. For instance, to manufacture each EV auto battery, you must process 25,000 pounds of brine for the lithium, 30,000 pounds of ore for the cobalt, 5,000 pounds of ore for the nickel, and 25,000 pounds of ore for copper. All told, you dig up 500,000 pounds of the earth's crust for just ONE battery.
Sixty-eight percent of the world's cobalt, a significant part of a battery, comes from the Congo. Their mines have no pollution controls, and they employ children who die from handling this toxic material. Should we factor in these diseased kids as part of the cost of driving an electric car?"
I'd like to leave you with these thoughts. California is building the largest battery in the world near San Francisco, and they intend to power it from solar panels and windmills. They claim this is the ultimate in being 'green,' but it is not. This construction project is creating an environmental disaster. Let’s see why.
Alternative Sources of Power for EV Batteries?
Solar: The main problem with solar arrays is the chemicals needed
to process silicate into the silicon used in the panels. To make pure enough
silicon requires processing it with hydrochloric acid, sulfuric acid, nitric
acid, hydrogen fluoride, trichloroethane, and acetone. In addition, they also
need gallium, arsenide, copper-indium-gallium- diselenide, and
cadmium-telluride, which also are highly toxic. Silicon dust is a hazard to
the workers, and the panels cannot be recycled.
Windmills are the ultimate in embedded costs and environmental destruction. Each weighs 1688 tons (the equivalent of 23 houses) and contains 1300 tons of concrete, 295 tons of steel, 48 tons of iron, 24 tons of fiberglass, and the hard to extract rare earths neodymium, praseodymium, and dysprosium. Each blade weighs 81,000 pounds and will last 15 to 20 years, at which time it must be replaced. We cannot recycle used blades.
There may be a place for these technologies, but you must look beyond the myth of zero emissions.
"Going Green" may sound like the Utopian ideal but when you look at the hidden and embedded costs realistically with an open mind, you can see that Going Green is more destructive to the Earth's environment than meets the eye, for sure.
