Tim’s experience in the energy sector—which is the key to addressing both traditional public health concerns and the greenhouse gas emissions that drive climate change—dates back to 1979. He first published reports on global warming in 1990 and has consulted with the largest wind, solar, geothermal, and landfill gas recovery companies in the world on regulatory policy and permitting. He has been an affiliated faculty member of the Energy and Resources Group at UC-Berkeley since 1991 and has taught renewable energy law and policy at Seattle University School of Law, energy politics and policy at UC-Santa Cruz, and climate change law and policy at the University of San Diego School of Law. The 9th Circuit, U.S. Court of Appeals has cited his research on energy regulatory policy and he has also published on the relationship between land use, transportation, and carbon emission offsets under California’s Global Warming Solutions Act (AB 32). Tim was also on the board of directors of Skyfuel, Inc., a concentrating solar power company, from 2007-2009.
