The world is trying to switch from electricity produced by burning fossil fuels to cleaner wind and solar power, but some people have worried that there aren't enough rare earth minerals to make the green electricity switch.
FILE - Refined tellurium is displayed at the Rio Tinto Kennecott refinery, May 11, 2022, in Magna, Utah. 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.
A team of scientists looked at the materials — many not often mined heavily in the past — and 20 different power sources. They calculated supplies and pollution from mining if green power surged to meet global goals to cut heat-trapping carbon emissions from fossil fuel. 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.
