We hear a lot about technologies that produce carbon-free energy, but what about actually using less energy to begin with? In this episode of TILclimate (Today I Learned Climate), Harvey Michaels, lecturer at the MIT Sloan School of Management, joins host Laur Hesse Fisher to explore the three ways that energy efficiency can help us reduce carbon emissions.Harvey Michaels, an MIT alumnus now lecturing at the MIT Sloan School of Management, researches energy management and efficiency and smart-grid-related opportunities to mitigate climate change. He is a member of Future of the Grid at the MIT Energy Initiative, Efficiency Forward at the Sloan Sustainability Initiative, and Project Faculty for Energy Democracy at the MIT Media Lab. Prior to joining MIT, Harvey Michaels worked at energy efficiency companies Xenergy and Aclara Software.Season two of TILclimate focuses on our global energy system, its relationship to climate change, and what our options are for keeping the lights on while creating a clean energy future. We're partnering with the MIT Energy Initiative, which will air longer interviews with each guest to take a deeper dive into these topics.For more episodes of TILclimate by the MIT Environmental Solutions Initiative, visit tilclimate.mit.eduFor related energy podcasts from the MIT Energy Initiative, visit:http://energy.mit.edu/podcast/For a list of U.S. energy efficiency incentives for by state, visit: https://www.dsireusa.org/Check out this case study on the Bullitt Center in Seattle, which achieved a certification called the Living Building Challenge. The building is so energy efficient, the solar panels on its roof generate more electricity than the building needs:http://www.bullittcenter.org/wp-content/uploads/2015/08/living-proof-bullitt-center-case-study.pdfWant to know how energy efficient your lightbulbs are?  Check out this comparison: https://www.energy.gov/energysaver/save-electricity-and-fuel/lighting-choices-save-you-money/how-energy-efficient-lightHere is a resource comparing the cost to fuel an electric car versus a gasoline car:https://www.energy.gov/articles/egallon-how-much-cheaper-it-drive-electricityCreditsLaur Hesse Fisher, Host and ProducerDavid Lishansky, Editor and ProducerJessie Hendricks, Graduate Student WriterAaron Krol, Contributing WriterDarya Guettler, Student Production AssistantMusic by Blue Dot SessionsArtwork by Aaron KrolProduced by the MIT Environmental Solutions Initiative at the Massachusetts Institute of Technology.
