MIT On Renewable Energy Demands: Minerals Mining Alone To Produce 29 Gt Carbon By 2050 [View all]

EDIT

Back to the solar example: China is selling its cheap solar installations all over the globe, and by 2030 could be responsible for half the new capacity of renewables installed planetwide. But the environmental cost of satisfying that escalating demand is rippling out across the world. It has spurred a huge mining boom. Desperate to satisfy fast-rising demand, companies and nations are mining in ever more inaccessible areas, which costs more in dollars, carbon emissions, biodiversity losses, land-use change, freshwater use, ocean acidification, plus land, water and air pollution. So, just as with fossil fuels, the rush to renewables contributes to the destabilizing of the nine planetary boundaries, of which six are already in the red zone, threatening civilization, humanity and life as we know it.

Mining, it must be remembered, is also still heavily dependent on fossil fuels, so it generates large quantities of greenhouse gases as it provides minerals for the renewables revolution. A January 2023 article in the MIT Technology Review predicts that the mining alone needed to support renewables will produce 29 billion metric tons of CO2 emissions between now and 2050.

Carbon is far from the only problem. Renewables also require a wide range of often difficult-to-get-at minerals, including nickel, graphite, copper, rare earths, lithium and cobalt. This means “paradoxically, extracting this large amount of raw materials [for renewables] will require the development of new mines with a larger overall environmental footprint,” says the MIT article.

There are other problems too. Every year 14,000 football fields of forests are cut down in Myanmar to create cheap charcoal for China’s smelting industries to process silicon, a key component of solar panels and of computers. This rapid development in rural places also comes with harsh human costs: Mongabay has reported extensively on how Indigenous people, traditional communities and fragile but biodiverse ecosystems are paying the price for the world’s mineral demand in the transition to renewable energy.
