A recent study says there are enough rare earth metals on Earth for new “low-carbon electricity generation” technologies. Rare earth metals come from minerals found in countries around the world. The researchers said more mining is needed to make more of the valuable metals available to industry. Rare earth metals are in demand for products such as magnets, wind turbines, solar panels and computers. All are part of the “green energy” push to remove carbon gases from electricity generation. The researchers said the amount of minerals available is enough to supply a switch to renewable energy. They wrote that the carbon gasses “related to electricity infrastructure may be substantial.” But the study said it would be between one and nine percent of the world’s budget for carbon gas production. The study came out recently in the science publication Joule.
