Abstract:<\/span><\/strong><\/p>\n

The challenge of sustainable energy encompasses both supply and demand. Energy demand is intertwined with the lifestyles and\u00a0choices of consumers. This talk addresses two aspects of energy and consumers: 1. How changing lifestyles affect energy use and\u00a02. How different energy consumers are from one another.
\nOn the first topic, lifestyles are changing due to Information Technology and other socio-technological trends. We attempt to\u00a0capture the energy effects of the time-use aspects of lifestyle changes. We use the American Time Use Survey (ATUS) to first find\u00a0shifts in times performing different activities from 2003\u20132012. The results show that an average American spends more time at\u00a0home (19 more hours per year). This increased home time is balanced by decreased time spent in cars (3 hours per year) and in\u00a0non-residential buildings (16 hours per year). Decomposition analysis is then used to estimate effects on energy consumption. The\u00a0model indicates American are saving energy by staying at home, around 1.8% of the national total over the decade.
\nOn the second topic, most of the ways societies manage energy use assume consumers are similar in energy use. For example,\u00a0energy use labels on appliances list savings for an average consumer. People use actual energy technologies very differently. In one\u00a0study we find huge differences in TV watching habits in the U.S: 14% of the population watches television 7.7 hours day, 34%\u00a0watches 3.5 hours, and 52% percent of the population and watches 1.1 hours a day. The heavy watchers will save more than seven\u00a0times the energy from buying an energy efficient TV compared to the light watching group. We find similar large differences in\u00a0usage patterns and energy savings of clothes washers and dryers. More personalized information telling consumers how they would\u00a0save energy from efficient technologies would increase the motivation of heavy users to get the right technologies.<\/p>\n

Eric Williams has been at the Rochester Institute of Technology since 2011. Eric\u2019s recent research focuses on understanding progress and diffusion of energy supply and demand technologies, drawing on perspectives such as cost forecasting, market heterogeneity, and thermodynamic limits. Much of his prior work addressed the environmental assessment of information technology, such as characterization of materials flows in semiconductor and computer manufacturing and international management of electronic waste. Dr. Williams\u2019 research is mainly funded by the National Science Foundation, with additional support from the Department of Energy and Ford Motor Company. He has published over 60 peer-reviewed articles, including in the journal Nature. He is also active in engaging outside of academia to disseminate research results. In 2008, he testified before a U.S. congressional committee developing legislation on electronic waste. His work has been covered in media in outlets such as USA Today, Science, and the BBC. He has also served on three committees of the National Research Council, one of the main organizations providing scientific input to national policy-making processes.<\/p>\n
