Listen to Andrea Kissack’s 2010 profile of Rosenfeld, produced for KQED’s Quest.
For decades, journalists couldn’t do a story on energy efficiency in California — or maybe anywhere — without somebody saying, “You really should talk to Art Rosenfeld.”
The physicist, who became known well beyond the confines of Lawrence Berkeley National Laboratory as the “godfather” of energy efficiency, died Friday at the age of 90.
Rosenfeld’s obituary on the Berkeley Lab website credits him with creating the field of energy efficiency — something the state of California has taken to heart. Atop the enormous gains and “billions of dollars” in energy savings attained under Rosenfeld’s influence and leadership, Governor Jerry Brown last year set a target of cutting energy use by buildings in half by 2030 — a goal that legislators have since made law.
KQED’s Andrea Kissack interviewed Rosenfeld when, at 83, he stepped down from his post on the California Energy Commission. His very first comment for the story is memorable.
