Evan Mills is currently a Senior Scientist at the U.S. Department of Energy's Lawrence Berkeley National Laboratory, one of the world's leading research centers on energy and environment with a staff of approximately 400 people, and past leader of LBNL's Center for Building Science.

He is a member of the international body of scientists known as the Intergovernmental Panel on Climate Change (IPCC), which 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 has worked as an energy and environmental systems analyst since the early 1980s—ranging from a local to global scale. He received his Masters of Science degree from the Energy and Resources Group at the University of California at Berkeley and his Ph.D. from the Department of Environmental and Energy Systems Studies at the University of Lund in Sweden. In Sweden, he worked for several years with the Swedish State Power Board and the Swedish National Board for Industrial and Technical Development on energy planning projects.

His research covers both the impacts of climate change and the means of mitigating those impacts through reduced emissions and loss prevention. Within the realm of impacts assessment, Dr. Mills 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 quality assurance of energy-efficiency projects ("commissioning"); energy in data centers, laboratories, and other high-tech facilities; efficient lighting; advanced data visualization; federal energy management; energy in low-income housing; utilization of the Internet for disseminating energy information and tools; and energy planning and policy. He leads 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.

He has published over 300 technical articles and reports and has contributed to ten books, including Global Climate Change Impacts in the United States, a definitive US government report published in 2009. He frequently writes for popular and trade publications, and has contributed to ForbesThe Los Angeles TimesTechnology Review, and The Washington Post.
