OECD Non-OECD Equivalent avoided installed capacity
China in 2004. These savings would avoid the need to build some 400 large
coal-fired power plants that would otherwise be needed in 2030.
More efficient household appliances cut electricity use by 714 TWh in 2030,
compared with the Reference Scenario, accounting for 31% of the total
electricity savings in the residential and services sectors. There is considerable
scope even within OECD countries to save electricity through measures that
stimulate the deployment of more efficient equipment. Electricity savings in
2030 in OECD are 88 Mtoe, slightly smaller then the 112 Mtoe savings in
non-OECD. About half of these savings are produced by a tightening of
between 10% and 30% in standards for appliance efficiency compared with
the Reference Scenario. However, potential savings are greater still. The
cost-effective savings potential 13 in household appliances amounts to 36% of
total residential electricity demand in the OECD. 14 Developing countries,
13. This potential is defined as the savings that could be achieved without any increase in the overall
cost of buying and running the appliance over its lifetime (IEA, 2003).
14. The IEA has launched initiatives to reduce electricity consumption in the residential and services
sectors. Noteworthy proposals include the IEA 1 Watt Plan and setting efficiency standards for
television “set-top” boxes and digital television adaptors. The IEA 1 Watt Plan proposes that all
countries harmonise energy policies to reduce standby power use to no more than one watt per
electronic appliance. Standby power is the electricity consumed by appliances while switched off or
not performing their primary functions. The potential savings in the IEA countries would be 20 GW
by 2020. Similarly, establishing efficiency standards for television “set-top” boxes and digital
television adaptors would save a further 8 GW by 2020 (IEA, 2006b).
