  2. 14,000 12,000 10,000 8,000 KWh 6,000 4,000 2,000 - 1960 1965 1970 1975 1980 1985 1990 1995 2000 US California Western Europe Energy Efficiency: first in the California energy “loading order” Per Capita Electricity Consumption Source: California Energy Commission

  3. 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

  4. 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

  5. PG&E’s Emerging Technologies (ET) program structure • Mass Market Portfolio – Lance Elberling • Food Service Tech Center – Bill Pietrucha • Industrial Portfolio – Francois Rongere • Commercial Portfolio – Wayne Krill • Lighting Portfolio – Mary Matteson Bryan

  6. PG&E’s Emerging Technologies network Accelerate Customer Implementation Assess Technologies & Markets Identify Opportunities Entrepreneurs Consulting Companies Universities Utility Customer Account Reps PIER Utility Program Managers Technology Providers Utilities Venture Investors Labs

  12. 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
