Molly Bertolacini

Molly Bertolacini is an experienced analyst and project manager with experience in building decarbonization, equity, electrification, energy efficiency, and project leadership. She joined E3 after earning her Master of Science in Civil and Environmental Engineering, focusing on Energy, Civil Infrastructure, and Climate from the University of California, Berkeley. She has worked as a Research Assistant at Lawrence Berkeley National Laboratory where she studied how to decarbonize buildings faster and more equitably.

Molly became interested in the energy sector while working at the Natural Resources Defense Council (NRDC) as a program coordinator in the People & Communities program and as the storytelling co-lead for the Energy Efficiency for All (EEFA) coalition. EEFA’s storytelling team aimed to humanize the technical work of energy efficiency and build partnerships with local organizations to support frontline storytelling initiatives on how energy efficiency improves people’s lives.

In her free time, Molly loves to take long walks to explore new cities, teach herself film photography, watch mystery movies, and take her dog to the local dog run.

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.
