• Mostly electricity and natural gas

• Electricity use has relatively little seasonal variation (mostly refrigeration and lighting)

• Natural gas consumption is highly seasonal

Residential energy use

Residential (22%) Commercial & public buildings (7%) = 29% of total energy use

(2004).

Residential electricity use

• Major end uses

• Refrigerators and freezers

• Lighting

• Video appliances

• Standby

• Air conditioning

• In recent years

• Energy consumption of some end uses have changed drastically: end-use breakdown not known

• Per capita electricity use stable 1999-2007, and decreased recently: refrigerators and lighting…

Refrigerator and freezer labeling

• Refrigerator label is identical in design and values to the EU label

• Finally put into place in 5/2005 (fridges)

• Spectacular impact, already by 7/2007:

Label not so useful:

• Incandescents are all E,F,G.

• Fluorescents and CFLs are all A or B

• Energy efficiency rating letter does not consider the useful life of lamp

•Most people do not know what label means

National Program for the

Rational and Efficient Use of Energy

Key elements (for building energy efficiency)

�Replace incandescent lamps by CFLs

�Develop Minimum Efficiency Performance Standards (MEPS) for major end uses

� Education

� Energy efficiency in public buildings

Conclusions

Significant energy efficiency improvements have been seen in recent years:

�Residential refrigerators: labels + manufacturer initiatives

� CFLs: consumer awareness + free distribution

� Building thermal envelope: builder initiatives

Future efficiency improvement:

� Ban on incandescents (2011)

�MEPS for refrigerators and air conditioners

� Eliminate pilots in gas water heaters

� Labeling and MEPS for gas appliances

� Labeling of building thermal envelope
