E3: Energy+Environmental Economics
Careers  |  Internship Program

Internship Program

Our Internship Program is designed to provide an opportunity for top students to work on emerging energy topics alongside our staff of industry experts. Master's and PhD candidates in science and engineering, economics, business, and policy are all encouraged to apply. The program is highly selective. Ideal candidates will combine enthusiasm for their topics, academic excellence, and relevant work experience.

Successful applicants will work with E3 experts on a range of topics over the course of the internship. Interns will also contribute to active E3 projects. The program is designed to:

  • Provide students with the opportunity to work in a professional consulting atmosphere in which their research can be put into immediate practice;
  • Provide students with an opportunity to develop a research "deliverable" that they can use as the basis of future research, publications, and applications;
  • Provide E3 with an opportunity to work with top students who may be interested in consulting careers after graduation.

Application Process

Please send the following application materials in electronic form to www.apply.co/ethree no later than February 10, 2017: your resume, unofficial transcript, one reference, and a cover letter (see link above or application page for guidelines).

Depending on the number of applications received, we will conduct either in-person or telephone interviews. Successful internship applicants will be notified by February 24, 2017. One to two interns will be selected in 2017.

No phone calls please.

Prior Interns and Projects +

Ben Haley (Summer 2010)
Ben received his M.A. in International Environmental Policy from the Monterey Institute of International Studies in May of 2010. During his summer internship, Mr. Haley conducted research on the water-energy nexus in California. He built a spreadsheet model of California’s urban water supply system in order to research the effects of California’s “20x2020” urban water conservation legislation on the state’s energy demand and greenhouse gas emissions. In addition, Mr. Haley examined the implicit value of water for solar thermal power plant cooling under a potential policy that would prohibit the use of potable water resources for cooling tower use.

Mr. Haley is now a Senior Associate at E3 working on water-energy issues as well as other E3 practice areas.

Elizabeth Martin (Summer 2009)

Elizabeth graduated from Colorado College and Columbia University with a dual B.A./B.S. in Physics/Mathematics and Mechanical Engineering. Following work as a propulsion engineer at The Boeing Company, she continued her work in energy studies with an M.S. in Management Science and Engineering at Stanford with a focus on Energy, Policy, and Strategy.  Elizabeth’s internship project at E3 focused on residential smart grid technologies and benefits thereof accruing to utilities, end-users, and market participants.

Following her E3 internship, Elizabeth became an Environmental Program Analyst at Hara Software in Redwood City, CA, aiding clients in sustainability strategy.


Dipti Desai (Summer 2009)
Dipti graduated from UC Berkeley’s Goldman School of Public Policy with a focus in energy policy where she was a Department Fellow. She holds a B.S. in Electrical Engineering from Virginia Tech. Dipti’s internship project focused on developing a regression-based estimation of Plug-in Hybrid Electric Vehicle (PHEV) adoption in the San Francisco Bay Area Region and modeling the impact of PHEV charging on utility system load.

Following her E3 internship, Dipti worked on finishing work on her master’s thesis while working at the CalCEF Angel Fund, a seed investment fund in the clean energy sector. She is now at the startup Hara Software where she is an Environmental Sustainability Consultant where she works with customers across industries and sectors to implement energy and sustainability strategy.

Jessica Shipley (Summer 2008)
Jessica received her Masters in Public Policy from the University of California, Berkeley, where she specialized in environmental and energy policy.  At E3, Jessica helped develop and refine a simple spreadsheet model of U.S. greenhouse gas (GHG) emissions and utilized it to demonstrate technology and policy choices necessary for achieving aggressive GHG cuts by 2050.

Following her E3 intership, Jessica became a Solutions Fellow at the Pew Center on Global Climate Change where she assists the Vice President of Innovative Solutions on state-level policy and on agriculture and forestry related climate issues.

Teddy Kisch (Summer 2008)
Teddy graduated from UC Berkeley with a B.A. in Environmental Science, and received his M. S. in Civil and Environmental Engineering from Stanford University with a concentration in Atmosphere/Energy.  Teddy’s E3 research project examined the potential of emerging technologies to help meet utility energy efficiency goals.

Teddy went to work for Energy Solutions in Oakland, CA focusing on a variety of innovative energy efficiency programs, including lighting and consumer electronics.

Lakshmi Alagappan (Summer 2007)
Lakshmi received her B.A. in Economics and M.S. in Civil and Environmental Engineering (Atmosphere/Energy program) from Stanford University.  During her summer internship at E3, Ms. Alagappan researched transmission interconnection and service policies for wind generators across 14 jurisdictions in North America to understand which policies facilitate wind development.

Ms. Alagappan is now a Consultant at E3 where her practice areas are Transmission Planning and Pricing, Renewables and Emerging Technologies, and Energy Efficiency and Demand Response.


Zack Subin (Summer 2007)
Zack studied physics and math at Harvard University and received a Masters of Science from UC Berkeley's Energy & Resources Group in 2008.  His Master's project continued his internship work at E3 in which he studied options for greenhouse gas emissions reduction in California's transportation sector.

Following his internship at E3, Zack returned to UC Berkeley's Energy and Resources Group as a Ph.D. student, studying the potential for abrupt climate change in the terrestrial Arctic.
