The world has enough rare earth minerals and other critical raw materials to switch from fossil fuels to renewable energy to produce electricity and limit global warming, according to a new study that counters concerns about the supply of such minerals.
“Decarbonization is going to be big and messy, but at the same time we can do it,” said study co-author Zeke Hausfather, a climate scientist at the tech company Stripe and Berkeley Earth. “I’m not worried we’re going to run out of these materials.”
Looking at mineral demands for batteries is much more complicated than for electric power and that’s what the team will do next, Hausfather said. The power sector is still about one-third to half of the resource issue, he said.There will be short supplies. For example,is a mineral used for magnets in wind turbines and a big push for cleaner electricity would require three times as much dysprosium as currently produced, the paper said.
