Cambridge Energy Alliance (CEA) is a City of Cambridge program that promotes energy efficiency and solar energy. Our goal is to save you money while also reducing Cambridge’s carbon footprint. Focusing on residents, businesses, and institutions in Cambridge, CEA provides outreach and access to energy efficiency resources, including retrofit programs offered by NSTAR, Cambridge’s primary electricity and natural gas provider.
