Dr. Evan Mills is a retired Senior Scientist at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (LBNL), operated by the University of California -- one of the world's leading research centers on energy and environment. He was past leader of LBNL's Center for Building Science, which represented the work of about 400 people, and Assistant Director of the Energy & Environment Division. He continues his collaborations with "The Lab" as an Affiliate and is also a Research Affiliate with the Energy and Resources Group at U.C. Berkeley. He consults widely for private industry and the public sector. He has published 371 articles and reports in his fields of interest, including contributions to 17 books. He has been a speaker at events in 21 countries

Evan is a member of the international body of scientists which as worked over the past three decades under the auspices of the Intergovernmental Panel on Climate Change (IPCC). The IPCC collectively shared in the Nobel Peace Prize for 2007 with former U.S. Vice President Albert Arnold (Al) Gore Jr. "for their efforts to build up and disseminate greater knowledge about man-made climate change, and to lay the foundations for the measures that are needed to counteract such change." He also participated in the U.S. Global Climate Change Research Program's third national assessment entitled "Global Climate Change Impacts in the United States."

Evan has worked as an energy and environmental systems analyst on projects ranging from local to global scales. While completing his Bachelors of Science degree in Conservation and Resource Studies at U.C. Berkeley in the mid-1980s, he studied and taught about green buildings with pioneering architect Sim van der Ryn before they were in vogue. He received a Masters of Science degree in 1987 from U.C. Berkeley's Energy and Resources Group and a Ph.D. in 1991 from the Department of Environmental and Energy Systems Studies under Thomas B. Johansson at Lund University in Sweden. While in Sweden, he worked closely with the Swedish State Power Board (Vattenfall) and the Swedish National Board for Industrial and Technical Development on national energy planning projects, while serving as an energy advisor to the Swedish Parliamentary Working Group on Energy Futures. He spent most of his career with LBNL. His closest mentor and collaborator there was Art Rosenfeld

Evan's research centers on the impacts of climate change and the means of mitigating those impacts through reduced emissions and enhanced resilience. His specialties are energy efficiency in buildings and industry and the intersection of energy technology, global climate, and risk management. His interests further center around pinpointing "sleeper" uses of energy and empowering policymakers, consumers, and non-traditional market actors to achieve improved efficiencies, reduce greenhouse-gas emissions, minimize adverse climate impacts, and capture non-energy benefits.  

Within the realm of climate-change impacts assessment, he studies the linkages between changes in natural systems and economic systems, particularly with respect to the insurance and financial services sectors. 

Within the realm of emissions reductions, his major areas of expertise include energy forensics and the business case for energy efficiency; quality assurance of energy-efficiency projects; energy in data centers, laboratories, indoor agriculture, and other high-tech facilities; energy use in computer gaming; federal energy management; real-estate appraisals for green buildings, energy in low-income housing; utilization of the Internet for disseminating energy information and tools; energy access in the developing world; and energy planning and policy more broadly. He founded the Home Energy Saver project—a do-it-yourself, web-based energy audit—which pioneered the development of web-based carbon and energy calculators, and has had nearly 10 million users to date.

Evan frequently writes for popular and trade publications, and has contributed to Forbes, The Guardian, The Los Angeles Times, The San Francisco Chronicle, San Francisco Examiner, Slate, Salon, Technology Review, and The Washington Post. His work has been reported in publications including The Atlantic, Bloomberg, The Boston Globe, Business Week, CBS Radio, CNN, Discover Magazine, The Economist, The Financial Times, Grist, High Times, Huffpost, The International Herald Tribune, Mother Jones, National Geographic, National Public Radio, Nature, Newsweek, The New York Times, The New Yorker, Politico, Popular Science, Rolling Stone, San Francisco Chronicle, Slate, Scientific American, Salon, Slate, Time, USA Today, The Wall Street Journal, and Wired.
