So much for Net Zero by 2050
Simon P. Michaux calls it “Minerals Blindness” — the inability to see that there are just not enough metals to get to Net Zero.
He is an Australian working for the Geological Survey of Finland. He’s an Associate Professor of Mineral Processing and Geometallurgy, and has added up the tonnage required to convert the first generation of the fleet needed (theoretically) to get to Net Zero. So that’s just 25 years worth of wind turbines, solar panels and batteries.
And then we need to do it all again?
Michaux estimates that we need 944 million tons of lithium alone to go Net Zero (the first time). But at the moment every year we dig up about 100,000 tons a year, or 0.01% of what we need to reach the Net Zero target. Current total known reserves of lithium throughout the world in 2022 are just 26 million tons. Total known (best guess) resources are 98 million tons).* Obviously as the price of lithium rises, we will find a lot more. We haven’t been looking for lithium very long so we may even find ten times as much. But at our […]
