In 2022, U.N. Secretary-General António Guterres declared that the “lifeline of renewable energy can steer [the] world out of climate crisis.” In saying so, he echoed a popular and tantalizing idea: that, if we hurry, we can erase the climate emergency with widespread adoption of renewables in the form of solar panels, wind farms, electric vehicles and more. But things aren’t that simple, and analysts increasingly question the naïve assumption that renewables are a silver bullet. That’s partly because the rapid transition to a global energy and transport system powered by clean energy brings with it a host of new (and old) environmental problems. To begin with, stepping up solar, wind and EV production requires many more minerals and materials in the short term than do their already well-established fossil fuel counterparts, while also creating a major carbon footprint. Also, the quicker we transition away from fossil fuel tech to renewable tech, the greater the quantity of materials needed up front, and the higher the immediate carbon and numerous other environmental costs. But this shift is now happening extremely rapidly, as companies, governments and consumers try to turn away from oil, coal and natural gas. “Renewables are moving faster than national governments can set targets,” declared International Energy Agency executive director Fatih Birol. In its “Renewables 2024” report, the IEA estimates the world will add more than 5,500 gigawatts of renewable energy capacity between 2024 and 2030 — almost three times the increase between 2017 and 2023. But this triumph…This article was originally published on Mongabay
