LOL So you disagree with the Milankovitch Cycles. Yet almost all scientists say that it is broadly correct. So we are to think some anonymous poster knows more than the scientists at NASA.
Milankovitch (Orbital) Cycles and Their Role in Earth's Climate – Climate Change: Vital Signs of the PlanetSmall cyclical variations in the shape of Earth's orbit, its wobble and the angle its axis is tilted play key roles in influencing Earth's climate over timespans of tens of thousands to hundreds of thousands of years.climate.nasa.gov
Scientists need funded somehow, why not jump onto the current social bandwagon and peddle the current tripe, those that say, "Hang on, that's not right", are sacked from the universities they belong to.LOL You mean like those real scientists that attend the annual meeting of the American Geophysical Union every year? You mean the real scientists that are members of the Geological Society of America, and state that AGU is real, and a clear and present danger? LOL
A lot currently, yes. For now.. However, we are transitioning:Natural gas is used instead now a days.
And, obviously, electricity generated from wind and solar is and will continue being used to recycle (purify and extrude) copper for reuse as a commodity. Next, steel:Copper is one of the best renewable resources. It is one of the few materials that can be recycled 100 percent over and over again without a loss in performance.
Renewable energy sources provide nearly one-quarter of the world’s power, and copper plays an important role in making it as efficient as possible with minimal impact on the environment.
Next, fiberglass:While the WSA points out that “in the last 50 years, the steel industry has reduced its energy consumption per tonne of steel produced by 60 percent” and notes that steel is infinitely reusable, and that “new” steel typically contain 30percent recycled steel on average the traditional methods of iron and steel production are becoming untenable — at least if we want to mitigate its impacts on climate change. What’s more, the International Energy Agency estimates that global steel production will grow by a third by 2050, which will only compound the industry’s environmental impacts. That’s where fossil-free steel comes in.
Take HYBRIT (Hydrogen Breakthrough Ironmaking Technology), for example. This process has been developed as a joint venture between three Swedish companies: SSAB, which makes steel, energy company Vattenfall, and LKAB, which mines iron ore. Rather than using coking coal and a blast furnace to convert raw iron ore into metallic iron, the HYBRIT method uses hydrogen generated from renewable energy sources and a technique known as direct reduction, which lowers the amount of oxygen contained within the ore without heating it above the metal’s melting point, to create sponge iron.
Hopeless naysayers and fossil fuel apologists are a dime a dozen. Too lazy to even search for existing alternatives rather than reflexively yap their crap.Siemens Gamesa calls its RecyclableBlade “the world’s first wind turbine blade that can be recycled at the end of its lifecycle,” and a “milestone” for the wind industry. But other companies are also working to keep turbine blades from filling landfills. In May 2021, wind turbine maker Vestas said it had a new technology to recycle blades (that company also has a goal to make zero-waste wind turbines by 2040). Startups like Global Fiberglass Solutions can press blades into fiber boards for flooring and walls.
Coke supplements the natural gas to increase the heat. You can not createNatural gas is used instead now a days.
I hate to break this to you, but that method you mention, if not for steel, it is not for HSS, HY-80 HY-100 or any of the many stainless steels.A lot currently, yes. For now.. However, we are transitioning:

electricity from wind and solar is not used to make copper, anywhere.
Your forgot to hurl in "commies"....apparently you missed your talking points for 23 October.No matter what any of the liberal-progressive-socialist-democrat-marxists think, and all their thinking and dreaming and worrying and fear-mongering is about tomorrow, they are wrong.
With all the "science" of the "chicken littles", there is nothing for today, everything is, "tomorrow we will find the solution to fix our failures of today.
