Dr. Liz Mettetal joined E3 in 2019. Her analysis, informed by her deep background in environmental and energy economics, helps clients evaluate climate and energy policies and informs electricity planning processes. She also leverages E3’s extensive modeling capabilities to help clients assess pathways to achieving economy-wide greenhouse gas mitigation goals.

Prior to E3, Liz spent four years in energy and environmental consulting at Abt Associates and NERA Economic Consulting. In those roles, she oversaw and performed economic analyses for utilities and federal agencies on topics related to energy, natural gas, water, waste, air quality, climate change, and transportation. Her doctoral research, at Harvard University, examined the potential health externalities of agricultural water use and incentives for environmental technology adoption.

Liz comes to E3 motivated by a strong desire to help utilities and regulators navigate a cost-effective transition to a decarbonized, reliable, more distributed grid. She values the opportunity to collaborate with diverse clients and stakeholders on projects that directly influence the evolution of the energy sector.

Born and raised in New England and based in E3’s Boston office, Liz is excited to expand E3’s impact on the East Coast, especially at a time of such profound technological, regulatory, and market change.

Education: PhD, public policy, Harvard University; BS, environmental engineering science with a minor in economics, Massachusetts Institute of Technology


WRI United States Decarbonization Scenarios | World Resources Institute, 2021

E3 worked with the World Resources Institute (WRI) to develop four scenarios of increasing ambition to reduce greenhouse gas (GHG) emissions across all sectors of the United States economy using E3’s US PATHWAYS and RESOLVE models. E3 collaborated with WRI to develop robust scenario definitions, collect publicly available data and assumptions, and create interactive spreadsheet results. The goal of the study was to understand the effect of high-impact federal policies on achieving 50% emissions reduction by 2030 and net-zero emissions by 2050. The analysis demonstrates the importance of key near-term building blocks, including: 1) aligning economics for customers and companies to adopt clean energy technologies; 2) aligning policy and institutions to remove barriers to technology deployment; 3) increasing consumer awareness and education to unlock higher levels of adoption; and 4) creating a transition plan for fossil fuel jobs to ensure a smooth transition.
