Ellen Rubinstein

Senior Consultant


After earning her master’s from the University of Pennsylvania, Ellen got her start in the clean energy field by responding to a job posting that—unbeknownst to her—was several years old. Turned out the consulting firm needed someone with her skills, and she’s been working in energy ever since. A generalist at heart, Ellen has worked for economics, engineering, and social marketing and evaluation firms, all focused on sustainable energy. She has conducted numerous technology and market assessments, and is currently excited by recent advancements in green buildings, community solar, and electric vehicles. At EMI, she helps our clients think through the logic behind their program designs and helps to strategically design enhancements to those programs. Ellen enjoys working collaboratively and digging into project details while regularly taking a step back to see how the research fits into the big picture.

  • What are the ideas that drive you?

    I want to have a clean and safe world for everyone to live in. A classmate once told me to “Look at the blue sky right now and appreciate it. It’s never going to be this blue again.” That off-handed comment really bothered me. It set me on a career path where I can do my part to keep tomorrow’s sky as blue as yesterday’s.

  • What are the problems you like to solve?

    I like to learn through my research and come up with real-world, practical solutions. I enjoy one-off projects that lead me down new and interesting niches in the energy world and that call for innovative solutions.

  • What is it like working with you?

    I strive to be communicative and approachable. I’ve been working in clean energy long enough now that I get to mentor people just coming into the field, and I really enjoy that role.
