Dr. Hummel is the founder of Clean Energy Works, which connects champions of energy efficiency and renewable energy with resources that accelerate investment in the deployment of clean energy solutions. In addition, Dr. Hummel serves on the board of Cleantech Open, the world’s largest accelerator built to find, fund, and foster the most promising cleantech startups and also on the board of Cornerstone Capital Inc.

In 2009, Dr. Hummel was appointed as the Senior Policy Advisor in the U.S. Department of Energy’s Office of Policy & International Affairs, serving through 2013. In that capacity, Dr. Hummel engaged a wide range of industry and public interest stakeholders to inform energy policy decisions on such topics as clean energy finance, water-energy interdependency, natural gas resource development, trade policy, climate change, environmental regulation and grid reliability. In addition to stewarding agency work on energy and climate policy development, Dr. Hummel founded the Water-Energy Technology Team within DOE and also led the DOE Energy Finance Working Group.

In earlier public service, Dr. Hummel served as a Congressional Science Fellow focused on energy and climate policy. Prior to moving to Washington, D.C., Dr. Hummel designed corporate energy strategies for clients of Silicon Energy, an energy software firm acquired by Itron, and later consulted briefly with the Google Energy & Climate team. Dr. Hummel was first hooked on energy technology innovation 20 years ago as a co-leader of the Clarkson University Solar Car Team, which designed and raced a highly efficient experimental electric vehicle across the country using only the power of the sun.

In graduate studies, Dr. Hummel researched ways to interpret energy scenarios for climate stabilization as one of the first to earn a doctorate degree from the Interdisciplinary Program on Environment and Resources at Stanford University and also has a Switzer Environmental Fellowship.
