In rock climbing, both muscle power and endurance training make up a successful climb. An accomplished climber can climb for extended periods of time without forgoing efficiency. That same level of endurance is needed for a successful climb to a stable, organization-wide energy efficiency program.
Each company that hires an EDF Climate Corpsfellow through Environmental Defense Fund is at a different point of its energy efficiency climb. I am currently completing my EDF Climate Corps fellowship at Cummins, an organization that is quite far along in implementing energy efficiency as part of its policies and forward-looking strategy.
