Art Rosenfeld (1926-2017)

Art Rosenfeld, Berkeley Lab scientist, scholar-activist, and public servant, transformed the field of energy efficiency from a research afterthought into a mainstream movement.

Along the way, Rosenfeld saved consumers billions of dollars, prevented billions of tons of carbon from accelerating climate change, and demonstrated to governors and Presidents alike that economic growth did not require more power plants.

For Rosenfeld, conservation and energy efficiency were not trivial or second rate. They were rigorous, applied science, rooted in real life experience. And as he took aim at energy inefficiencies—from buildings and lighting to appliances and computers—he inspired countless scientists and scholars around the world to do the same.
