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

PG&E Energy Efficiency Emerging Technologies for AB32 objectives• 60 ET energy efficiency projects in process
• Increasing number of opportunities
• 7.9 GWh or 4,338 tons of CO2 reduction in 2006 – 1 project, refrigerant charge & airflow
• Energy Efficiency Emerging Technologies are :
– A major resource of CO2 generation reduction
– Quick to implement
– Economically attractive: payback periods are commonly shorter than 4 years
