Energy Efficiency in California Why We Should All

Energy Efficiency in California— Why We Should All Be Proud of What We Do Otherwise what we in the energy business call the “Rosenfield slides” October 2011

Art Rosenfield • • • Arthur H. Rosenfeld received his Ph. D. in Physics in 1954 at the Univ. of Chicago as the last graduate student under Enrico Fermi, and then joined the Department of Physics at UC Berkeley. There he joined, and eventually oversaw, the particle physics group of Luis Alvarez at Lawrence Berkeley National Laboratory until 1974. He changed his focus to the efficient use of energy, formed the Center for Building Science, and led it until 1994. From 1994 to 1999 he was Senior Advisor to the U. S. DOE’s Asst. Secretary for Energy Efficiency and Renewable Energy. In 2000 Governor Davis appointed him as a CEC Commissioner, & Governor Schwarzenegger reappointed him in 2005. There, he was responsible for the CEC’s research program; for energy efficiency, including the EE standards for buildings and for appliances; and collaborated with the PUC to oversee California's Energy Efficiency Program. He retired from the CEC in 2010. He is the author or co-author of nearly 400 publications and received many awards. He is most proud to have received in 2006 the Enrico Fermi Award, the oldest and one of the most prestigious science and technology awards given by the U. S. Government. He developed and used a variety of graphs to show the importance of energy efficiency and California’s importance in this area.
