    Tim Rosenfeld has worked for over 25 years on sustainable energy policy and development in both the public and private sectors. He has worked extensively with local governments to develop innovative local policies and programs to promote energy efficiency and renewable energy.
    Mr. Rosenfeld is one of the pioneers in the development and implementation of energy efficiency and renewable energy programs beginning in the late 1970s at the California Energy Commission and the Local Government Commission. He worked with cities and counties throughout California to implement local energy initiatives. He developed or managed wind farms through the 1980s with Pacific Wind & Solar and American Diversified Corporation.

He teamed with the Local Government Commission in 2001 to create Regional Energy Authorities in Humboldt and Ventura Counties. As a consultant to Marin County and cities from 2003 to 2010, he helped develop, fund and served as Director of the Marin Energy Management Team. The Team provided comprehensive technical and financial assistance to all of Marin local governments, school districts, and special districts to implement energy efficiency and renewable projects. It obtained over $40 million in federal allocations for zero-interest bonds (CREBs) for solar projects on Marin public facilities. He also consulted on the energy and water resource policies for the countywide plan update and the feasibility and development of community choice aggregation.
