Mining requires a lot of explosives. 300 holes, each containing 1 ton of anfo. The toxic dust from the explosion would settle miles away. This is just another aspect of what it takes to make #GreenEnergy But they wont talk about that.
Replacing hydrocarbons with green machines under current plans, never mind aspirations for far greater expansion, will vastly increase the mining of various critical minerals around the world.
A single electric car battery weighing 1,000 pounds requires extracting and processing some 500,000 pounds of materials. Averaged over a battery’s life, each mile of driving an electric car “consumes” five pounds of earth.
Current clean-energy scenarios imagined by the World Bank (and many others) will require a 1,000%–4,000% increase in neodymium, mining of indium, 8,000%, cobalt 300%–800% and lithium 2,000%

This is the Cerrejon coal mine in Colombia, it's the biggest open-cast coal mine in Latin America and one of the largest surface coal mining operations in the world. It is having detrimental impacts on the environment and on local communities. #GreenEnergy 🧵
It takes a great deal of this coal to make what? Solar wafers. In fact in order to make 1 ton of MG-Si (Kato, et. al) it takes 550 kg of this coal and for 1 ton of MG-Si (Globe) it takes 1.4 tonnes.
The Cerrejón open-pit mine in Columbia supplies “Blue Gem” coal, a primary source of carbon for
solar silicon smelters around the world.
Sulfuric acid is called the “king of chemicals” because it is the most widely used chemical on earth. Over 260 million metric tons were produced in 2021 #GreenEnergy 🧵
Sulfuric acid is essential for electric vehicles, batteries, solar, wind turbines, semiconductors and other green technology, because sulfuric acid is how you get lithium, cobalt, nickel, copper, and some rare earth metals by dissolving the rock around them.
But over half is used for the most important product of all, dissolving phosphate out of rocks to make phosphate fertilizer, which can increase crop production by 50%, to grow our fuel: food.
Solar panels with the power capacity of a gigawatt (750K homes) need about 18.5 tons of silver, 3,380 tons of polysilicon and 10,252 tons of aluminum. It takes 3.125 million solar panels needed based on panel size of 320 watts. How much mining is required? #GreenEnergy 🧵
To make 1 ton of polysilicon, (MG-Si Kato, et. al) it takes 2.4 tons of quartz, 550 kg of coal, 600 kg charcoal and 300 kg of woodchips. Why do we burn coal and trees to make solar panels? hiddenhistorycenter.org/wp-content/upl…
8,112 tons of quartz, 1,859 tons of coal, 2,028 tons charcoal and 1,014 tons of woodchips, just for the 3,380 tons of polysilicon. Now imagine the fossil fuels needed to mine this.
Solar Panels: silicon producers use “charcoal plantations,” but they only supply a fraction of the current demand of carbon for silicon production. The rest of the carbon supply come's from imported coal or coke, or the cutting and burning of “virgin” rainforest. #GreenEnergy
MG-Si is the result of purifying silicon using heat and reducing agent. The silicon may be 99% purse. Additional processing is completed until ultrapure electronic grade silicon (EG-Si) is obtained. For for one ton (t) MG-Si (Globe) it requires 2.4 Tons of woodchips.
A single polysilicon plant like this one in Tennessee, USA. can draw 400 megawatts of electricity, enough power for about 300,000 homes. (Wacker Polysilicon)
Something the #GreenEnergy advocates never want to talk about is the environmental damage so called "renewables" do to the planet. I mean who cares about a vast man-made lake of poison in northern China, as long as it's not in my backyard. Right? 🧵
Much of China’s green energy boom was supported by a phenomenal growth in coal consumption which rose from 300 million tons annually in 1970 to 4.3 billion tons last year.
As a consequence, the air is unbreathable in many cities, and soil contamination has left 20% of China’s arable land too polluted to grow crops safely. The air is so polluted the chimneys from a smelting plant are barely visible.
Welcome to the reality of mining underground. Could you do it? We used to joke, if there was a massive cave in, our families would save thousands in funeral costs.
Not all underground mines are like this of course. 100s of pieces of equipment. The equipment has to be taken a part/cut up and lowered down the shaft and reassembled.
