Mashable: Do Something Good for Earth Day

Institute Research Fellow Roger Turner talks about rare earth elements in this article about green technology.

Roger Turner, a research fellow at the Science History Institute in Philadelphia, has a focus on 20th-century science and the history of air pollution. He knows well how technological advances in transportation have both helped and hindered cleaning up the air in the past 60-plus years.

In a recent phone call, he noted that electric vehicles can work well with sustainable energy sources like solar and wind, even if most of our electricity isn't coming from those sources now. “EVs can quite significantly reduce the global pollution of carbon dioxide that's contributing to climate change,” he said.
