Daniel Kammen is the Class of 1935 Distinguished Professor of Energy with appointments in the Energy and Resources Group, the Goldman School of Public Policy, and the Department of Nuclear Engineering. Kammen is the founding director of the Renewable and Appropriate Energy Laboratory (RAEL) and is the director of the Transportation Sustainability Research Center (TSRC). Kammen’s research is focused on energy systems science in the context of decarbonizing the energy systems in the United States/North America, and in a range of field-based programs in Africa, Latin America, southeast Asia, and Europe.

Kammen was trained in physics and develops analytic and computational methods derived from a physical science/engineering perspective to inform and engage in analysis of energy futures.

During 2010 – 2011 Kammen served as the first Chief Technical Specialist / Director for Renewable Energy and Energy Efficiency. He now serves as a World Bank Fellow in Energy. In April 2010 Secretary of State Hilary Clinton introduced Kammen as the Energy Fellow / Envoy of the U. S. State Department’s Energy and Climate Partnership for the Americas (ECPA). The speech was previously available on the U.S. Department of State website.

Kammen’s research and the RAEL and TSRC is based in physical science modeling to inform interdisciplinary sustainability approaches to the systems science of energy. His current research efforts are focused around:

According to a new study by UC Berkeley researchers, population-dense cities contribute less greenhouse-gas emissions per person than other areas of the country, but these cities’ extensive suburbs essentially wipe out the climate benefits.

The release today (Friday, Sept. 27) of Assessment Report 5, a new report by the Intergovernmental Panel on Climate Change (IPCC), bolsters the conclusions of its 2007 report that humans are responsible for global warming, and it highlights the need for immediate action to reduce carbon emissions.

UC Berkeley-led researchers have found a dramatic one-third reduction in severe pneumonia diagnoses among children in homes with smoke-reducing chimneys on their cookstoves. Reducing wood smoke could have a major impact on the burden of pneumonia, the leading cause of child mortality in the world, the researchers said. A separate pilot study also found a link between prenatal maternal exposure to woodsmoke and poorer performance in markers for IQ among school-aged children.

A UC Berkeley analysis of the carbon footprints of households around the country shows that consumers need different strategies in different cities to reduce their greenhouse gas emissions. An online “carbon calculator” helps consumers decide how to change their lifestyles for the maximum reduction in their footprints.

A clean-energy initiative in rural Nicaragua shows that developing nations can take cost-effective steps to reduce carbon emissions while helping the rural poor to reduce their energy expenses, according to researchers at UC Berkeley. Their report inScience analyzes simple steps taken by Nicaraguan government and the nonprofit blueEnergy on that country's Mosquito Coast.
