PG&E’s ambitious 3-year goals for Energy Efficiency Equivalent of a (600 MW) large power plant and the gas consumption of 90,000 new homes
Emerging Technologies program provides new measures to renew Energy Efficiency portfolio At this point solutions are in the baseline. They do not contribute any more to PG&E’s efficiency goals. ET brings new technologies over the “chasm” between early adopters and large-scale deployment
