Batteries do not create electricity, but they store electricity produced elsewhere, especially through coal, uranium, natural power plants or diesel-powered generators.

So the claim that an electric car is a zero-emission vehicle is not true at all, because the electricity produced comes from power plants and many of them burn coal or gas.

So the 40% today ??????? of electric cars on the road are carbon-based.

But that’s not all.

Those who are excited about electric cars and a green revolution should take a closer look at batteries, but also wind turbines and solar panels.

A typical electric car battery weighs 450 kg, about the size of a suitcase. It contains 11 kg of lithium, 27 kg of nickel, 20 kg of manganese, 14 kg of cobalt, 90 kg of copper and 180 kg of aluminum, steel and plastic. There are over 6,000 individual lithium-ion cells inside.

To make each BEV battery, you will need to process 11,000 kg of salt for lithium, 15,000 kg of mineral for cobalt, 2,270 kg of resin for nickel, and 11,000 kg of copper mineral.

In total, you have to haul 225,000 kilograms of soil for one battery.

The biggest problem with solar systems is the chemicals used to convert silicate into the gravel used for the panels.

To produce enough clean silicon, it must be treated with hydrochloric acid, sulfuric acid, fluoride, trichloroethane and acetone.

In addition, galium, arsenide, copper-indio-galium diselenide and cadmium telluride, which are also highly toxic are needed.

Silicone dust poses a hazard to workers and tiles cannot be recycled.

Wind turbines are not plus-ultra in terms of cost and environmental destruction.

Each windmill weighs 1,688 tons (the equivalent of the weight of 23 houses) and contains 1300 tons of concrete, 295 tons of steel, 48 tons of iron, 24 tons of fiberglass and the rare lands hard to obtain Neodymium, Praseodymium and Dyprosium.

Each of the three shovels weighs 40,000 kg and has a lifespan of 15 to 20 years, after which they must be replaced. We cannot recycle used rotor blades.

Sure, these technologies may have their place, but we need to look beyond the myth of free-to-broadcast. “Going Green” may sound like a utopian ideal, but if you look at the hidden and embedded costs in a realistic, impartial way, you’ll find that “Going Green,” today, does more damage to Earth’s environment than it seems.

I’m not against mining, electric vehicles, wind power or solar. But reality is not so ideal.
