@BrknMan @aDissentient @7Kiwi MW not GW, it's late.
@BrknMan @aDissentient @7Kiwi I will say its possible for outliers. HR3 is a shallow, near shore farm and it was built before turbine costs shot up.
That's not the trend were seeing in the UK.

The debt ceiling is a relic that no longer serves a purpose in guiding our economic policies. It's time to remove it and put the needs of all Americans first. #MMT #DebtCeilingRemoval
Refusing to raise the debt ceiling will only lead to chaos and economic turmoil. As per MMT, our government can never run out of money it issues its own currency. Let's remove this outdated constraint and invest in vital public services. #RemoveDebtCeiling #MMT
Removing the debt ceiling will allow us to allocate resources based on human needs rather than being held hostage to arbitrary financial metrics or political folly. It's time to take a more pragmatic and responsible approach to investing in our future. #MMT #PublicServices
A #GreenEnergy thread: How are EV batteries recycled?
Two ways, pyrometallurgy and hydrometallurgy. The more common is pyrometallurgy, in which recyclers first mechanically shred the cell and then burn it, leaving a charred mass of plastic, metals, and glues.
Two ways, pyrometallurgy and hydrometallurgy. The more common is pyrometallurgy, in which recyclers first mechanically shred the cell and then burn it, leaving a charred mass of plastic, metals, and glues.
At that point, they can use several methods to extract the metals, including further burning. “Pyromet is essentially treating the battery as if it were an ore” straight from a mine. Hydrometallurgy, in contrast, involves dunking battery materials in pools of acid
producing a metal-laden soup. Sometimes the two methods are combined. Hydrometallurgy can extract materials not easily obtained through burning, but it can involve chemicals that pose health risks. And recovering the desired elements from the chemical soup can be difficult.
Today I want to talk about environmental issues.

Have you heard of the #Documerica project by the US Environmental Protection Agency (#EPA)? In the early 1970s, just after the birth of EPA and the environmental movement, the agency hired freelance photographers to record the state of the environment and efforts to improve it.
#Documerica ultimately collected tens of thousands of photos that serve as a visual baseline for comparing how our environment looked then with how it looks now and in the future. By 1974, Documerica had produced more than 81,000 photographs by more than 100 photographers.
So lets take a look at the new "Green" VW battery being built in Canada. How Green is it? The battery chemistry is Lithium iron phosphate or lithium ferro-phosphate (LFP). It requires Manganese, phosphate, iron, and lithium. #GreenEnergy 🧵
The worlds largest manganese resources are located in two South African mines: South 32’s open-cut Mamatwan mine and Black Rock mine located in Kuruman, South Africa.
After mining, drilling, blasting, diesel fuel, electricity made from coal fired plants, water, floatation, chemicals and toxic tailings ponds. The next step is ..
800 sq. ft. of solar panels weigh 1 ton. 2.5 lbs per sq. ft. 40-340 watt panels is what's needed to power a typical family home. This depends on sun zone, amount of snow cover etc. Approx. cost $10,000 dollars for panels. 10K divided by 20 yrs.=$500 per yr. #GreenEnergy 🧵
There is approx. 140 million housing units in the United States. 112000000000 sq. ft. of solar panels would be needed to power just the homes excluding all industry. 4017.44 sq. miles of panels. How much mining/manufacturing do we have to do to make that amount of solar panels?
280000000000 lbs or 140000000 tons. So we know in order to make one ton (t) MG-Si (Kato, et. al) (solar wafers for solar panels) it takes 2.4 tons of quartz, 550 kg of coal, 200kg oil coke, 600kg charcoal and 300 kg of woodchips. This excludes glass, plastic, copper and aluminum.
#ClimateChange is a natural process that occurs over 1000s of years. The reason they say #GlobalWarming is wreaking havoc is due to the human caused CO2 increase. CO2 is necessary for plants & trees to produce food. Due to excessive deforestation and burning of fossil fuels… twitter.com/i/web/status/1…
Here’s a prev 🧵 on #ClimateChange
If you haven’t watched this clip about #ClimateChange it’s a must watch🔥
Mining tailing ponds are among the largest and most dangerous structures engineered by humanity. #GreenEnergy is expected to increase the demand for certain minerals 30- to 800-fold, which means a lot more toxic tailings ponds worldwide. 🧵
The world’s 29,000-35,000 existing active, inactive and abandoned tailings storage facilities contain approximately 223 billion tonnes (534 billion cubic meters) of tailings waste.
Every one million tonnes of mined mineral product generated requires physical and economic provision to also manage 4.9 million tonnes of waste ore, waste rock and tailings.
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.

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.
Did you know that Europe is currently facing an energy crisis? ⚡️ With energy prices at record highs, it's more important than ever to find solutions. Follow this thread for a comprehensive guide on how to beat the European energy crisis. #EnergyCrisis

The first step to beating the European energy crisis is to reduce energy consumption. 💡 Simple changes such as turning off lights and unplugging devices when they're not in use can make a big difference. #EnergySavingTips #ReduceEnergyConsumption
Another way to beat the European energy crisis is to invest in renewable energy sources such as solar and wind power. 🌞🌬️ Not only is this better for the environment, but it can also save you money in the long run. #RenewableEnergy #GreenEnergy
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.
Let's talk about Biomass. To produce just 10% of U.S. electricity (405 TWh) it would require harvesting and burning wood plantations the size of Minnesota every year. #GreenEnergy 🧵
Burning wood emits carcinogens, NOx, carbon monoxide, Sulphur dioxide, carbon dioxide, antimony, arsenic, cadmium, chromium, copper, dioxins, furans, lead, manganese, mercury, nickel, polycyclic aromatic hydrocarbons (PAHs), selenium, vanadium, and zinc.
Now imagine all the energy that went into building the power station and emission controls, planting and logging tree plantations, trucking the biomass to the power station, chipping it into smaller bits, and burning it at only 35% efficiency or less.
According to the Ontario Society of Professional Engineers:
Carbon Dioxide Emissions will increase by 48% in 2030,
because gas plants constantly starting up and shutting down expel more emissions than if they ran continually. #GreenEnergy

This is what my part of the country used to look like. Farmland.
This is what it looks like now.
$6.7 trillion invested in #GreenEnergy since 2004. To continue this green dream the world will need 10 million tons of new copper supply over the next decade, or the equivalent of a new Escondida copper mine, the biggest in the world, into production every year. #GreenEnergy
The Chinese copper smelter Guixi had the largest production capacity worldwide, amounting to some 900 thousand metric tons as of June 2022. In the process the smelter has caused cadmium, arsenic, copper and lead contamination in the soil and water.
Coal remains at the heart of China's flourishing green economy. In 2019, 58 percent of the country's total energy consumption came from coal, and China continues to build coal-fired power plants at a rate that outpaces the rest of the world combined.
It took 10,144,035 tons of Coal, 50,084,600 tons of Quartz, 11,271,150 tons of Charcoal and 5,635,575 tons of Woodchips to build this 345 acre 196,320 panel solar field in China, and that's just the metallurgical-grade silicon, not any copper, steels or plastics. #GreenEnergy

This 1 ton rock contains between 0.6 and 1 per cent of copper. One ton of ore generates a maximum 6 to 10 kilograms of copper. Depending on the size of battery, an electric bus can use between 224 and 369 kg of copper. How do we get the copper out of the rock? Mining 🧵
To start with we have to do a whole lot of mining. Mining requires massive amounts of equipment, fuel, oil and electricity. This shovel requires 4160 Volts to operate.
But before we get into that first we need core samples. Core samples determine whether or not we have a mineable property. How do we get core samples? We call in the diamond drillers.
