Use of air-conditioning is increasing as temperatures rise due to climate change, leading to growing demand for energy. Changes in demand in Los Angeles are reported in a study led by ASU researchers, including Mikhail Chester, a Fulton Schools associate professor of civil, environmental and sustainable engineering, and Janet Reyna, a Fulton Schools doctoral graduate now at the National Renewable Energy Laboratory. A potential remedy to the problem was addressed by Chester and Reyna in an earlier study in which they recommended “aggressive” energy efficiency measures to offset the impact of growing energy demand for both electricity and natural gas use. Solutions to such challenges are the focus of work at ASU’s Metis Center for Infrastructure and Sustainable Engineering, which is directed by Chester. The MIT Technology Review article that draws on results of these research efforts is updated from its original version published September 1.
