Read quote “Building one wind turbine requires 900 tons of steel, 2,500 tons of concrete and 45 tons of nonrecyclable plastic. Solar power requires even more cement, steel and glass—not to mention other metals. Global silver and indium mining will jump 250% and 1,200% respectively over the next couple of decades to provide the materials necessary to build the number of solar panels, the International Energy Agency forecasts. World demand for rare-earth elements—which aren’t rare but are rarely mined in America—will rise 300% to 1,000% by 2050 to meet the Paris green goals.” (Manhattan institute) Source
“The Democratic Republic of the Congo produces 70% of the world’s raw cobalt, and China controls 90% of cobalt refining. The Sydney-based Institute for a Sustainable Future cautions that a global “gold” rush for minerals could take miners into “some remote wilderness areas [that] have maintained high biodiversity because they haven’t yet been disturbed.” (Manhattan institute citing Dutch government study) https://www.manhattan-institute.org/if-you-want-renewable-energy-get-ready-to-dig
“What’s more, mining and fabrication require the consumption of hydrocarbons. Building enough wind turbines to supply half the world’s electricity would require nearly two billion tons of coal to produce the concrete and steel, along with two billion barrels of oil to make the composite blades. More than 90% of the world’s solar panels are built in Asia on coal-heavy electric grids.” (Manhattan Institute) https://www.manhattan-institute.org/if-you-want-renewable-energy-get-ready-to-dig
