The transition away from fossil fuels and toward clean energy will require massive amounts of metals that go into the production of electric vehicles, batteries, induction stoves, wind turbines and solar panels. Do enough of these metals exist to get the job done? Where can they be found and can they be extracted in a sustainable manner that doesn't lay waste to our environment? For answers, we turn this month to Dr. Adam Simon, Professor of Earth and Environmental Sciences at the University of Michigan. His work focuses on the global flow of energy and mineral resources with an emphasis on the geologic availability of energy critical metals. Adam has co-authored two textbooks and published seventy papers in the field of energy and mineral resources.
