Where will the materials for our clean energy future come from?

The Verge

Though ore demand for materials usually means more mining (and with it, increased environmental impacts), experts agree that the benefits of renewable energy far outweigh the costs. “There is no such thing as a free lunch,” says Charles Barnhart, a professor of energy studies at Western Washington University. “But I want to be clear that when we talk about environmental impacts, we’re not trying to decide between ‘lesser evils.’” For Barnhart, deciding between more mining for renewables and continuing to rely on fossil fuels is deciding between “completely different sides of the spectrum” because the cost of a business-as-usual future with fossil fuels will cause so much harm.
