  1. Energy Efficiency:Expanded Scale of Opportunities Arshad MansoorVice President,Power Delivery & Utilization, EPRI 2008 Summer SeminarAugust 4, 2008

  2. Carbon Footprint of End Use Energy in U.S., 2006 In a Low Carbon Future Carbon Footprint Becomes the Primary Metrics to Gauge the Scale of Energy Efficiency DOE EIA, Annual Energy Outlook 2008, Tables A2. and A18.

  3. The Expanded Scale of Energy Efficiency • Traditional Energy Efficiency Measures • Reducing carbon footprint by reducing use of electricity through increasingly higher efficiency • Electrifying End Use Processes • Reducing carbon footprint by replacing direct combustion of fossil fuel in end use processes with low carbon electricity • Electrifying Transportation • Reducing carbon footprint by replacing direct combustion of petroleum with low carbon electricity Significant Opportunity to Expand the Scale of Energy Efficiency

  4. Low Carbon Generation is the Key Decarbonizing the Electricity Sector Increases the Opportunity to Reduce Carbon Footprint Through Efficient Use of Electricity

  5. Traditional Energy Efficiency Measures: End to End Breakdown of Electricity Use Residence/ Buildings Industries Transmission Distribution Generation ~5% ~3% ~5% ~62% ~25% Significant Opportunity to Improve End to End Efficiency Electricity Industry is the Single Largest End User of Electricity

  6. Appliance Efficiency: Codes and Standards Decrease in Energy Use for Three Major Appliances (Source: S. Nadel, ACEEE, in ECEEE 2003 Summer Study, www.eceee.org)

  7. Next Generation Appliances: Codes & Standards • Increase in electricity use by adding a 46” plasma and a set-top box:~860 kWh/yr/household or 2.7% of US Electricity Consumption • Increase in electricity use by adding one digital photo frame per household: ~Five 250MW Generation Plant Plasma TV (~250W), Set-top Box (~30W) Digital photo frame (6W-15W) By 2030 almost 30% of residential load will be “plug connected” (DOE/EIA Annual Energy Outlook 2007)

  8. Electrifying End Uses: Heat Pump Example 41% Reduction in Energy and 32% Reduction in Carbon Footprint Power system losses based on average U.S. generation mix, AFUE: Annual Fuel Utilization Efficiency; COP: Coefficient of Performance DOE EIA Annual Energy Review 2006.

  9. Japanese Heat Pump Technology R&D • New heat pump technologies emerging • Heat pump water heaters - 5.2 million in Japan by 2010 • Heat pump washer/dryer • 6% of global CO2 reduction using Heat Pumps (IEA) • Electric utilities sponsored R&D • EPRI has initiated a large scale demonstration project on emerging heat pump technologies Heat Pump Water Heater Heat Pump Washer Dryer [1] International Energy Agency Heat Pump Centre, http://www.heatpumpcentre.org/About_heat_pumps/Energy_and_CO2.asp

  10. Benefits of 20 Mile Range PHEV Annual Energy Consumption and Carbon Footprint Impact

  11. Example: Expanded Scale of Energy Efficiency PHEV 20 Replaces Mid-Size Car Heat Pump Replaces Gas Furnace Energy Efficiency Improvements Single-Family Home

  12. Baseline: Energy Use & Carbon Footprint

  13. Deploying Traditional Energy Efficiency

  14. Deploying Heat Pump Technology

  15. Deploying 20 Mile PHEV

  16. Opportunity for Expanding Scale of Energy Efficiency Effects of Traditional Energy Efficiency, Heat Pump Heating & Cooling, Mid-Size PHEV, and Low Carbon Generation

  17. Infrastructure Need For Expanded Scale of EE Need All Infrastructures to Evolve To Significantly Reduce Carbon Footprint Through Efficient Use of Energy
