Ameresco, Inc.
A North America- and Europe-based energy services company that helps governments, schools, and businesses cut energy use and go renewable. It upgrades buildings with efficient lighting, HVAC, and controls, and builds and runs solar, wind, biogas, and electric-vehicle-charging projects, often under contracts guaranteeing energy savings. Founded in 2000 by energy-industry veteran George Sakellaris, the idea was reportedly sketched on a napkin at a Joe's American Bar & Grill in Dedham, Massachusetts. Its name blends "America" and "ESCO," short for energy service company.
