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.

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

Generation Transmission DistributionResidence/ Buildings
~5% ~3% ~5% ~62%
Significant Opportunity to Improve End to End Efficiency
Industries
Breakdown of Electricity Use
~25%
Electricity Industry is the Single Largest End User of Electricity

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)

Next Generation Appliances: Codes & Standards
Plasma TV (~250W), Set-top Box (~30W)
By 2030 almost 30% of residential load will be “plug connected” (DOE/EIA Annual Energy Outlook 2007)
• 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
Digital photo frame (6W-15W)

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
