Sam Lang supports E3’s Climate Pathways and Electrification practice area, working on both future of gas and energy policy-related projects. She joined E3 after completing a Master of Public Administration in Environmental Science and Policy at Columbia University. At Columbia she took environmental and energy-related courses including Renewable Energy Project Finance Modeling, Carbon Pricing, and Green Buildings. While earning her M.P.A., she worked as a research assistant at Columbia’s Center on Global Energy Policy, and conducted research on the future of natural gas, carbon capture and storage, and electric vehicles.

She previously worked five years in financial services before making a career shift to better align her work with her passion for environmentalism. While working in finance, she focused on fixed income securities and markets.

New York City Long-Term Energy Plan | New York City Mayor’s Office of Climate and Environmental Justice, 2022-2023

E3 led a team completing an inclusive, year-long study to identify the policies and programs needed to achieve the New York City’s decarbonization goals. E3’s analysis involved both examining policies and programs to meet the city’s long-term goals as well as providing specific recommendations for actions to be taken during the current administration. The study included eight research branches focused on the performance and cost of heat pumps in new buildings; the affordability of electrification retrofits in rent-regulated housing; the opportunities for electric school bus managed charging and vehicle-to-grid; the potential for in-city wind energy; a screening of public lands for new clean energy development; an assessment of the electric grid readiness for increasing heat pump and EV charging loads; and an evaluation of how bulk energy storage could reduce reliance on in-city fossil generation. Based on E3’s study, New York City published PowerUp NYC, the city’s first Long-Term Energy Plan, which includes 29 clean energy initiatives focused on the city’s energy grid, its buildings, and its transportation sector. Many aspects of the PowerUp NYC, from research topic selection to recommendations, were developed in collaboration with the public, and with the public’s interest at the forefront of the decision-making process. The recommendations of the LTEP are aligned with long-term energy and equity policy mandates from both the city and state and revolve around the needs of NYC residents.
