『Abstract
China has implemented a series of minimum energy performance
standards (MEPS) or over 30 appliances, voluntary energy efficiency
label for 40 products and a mandatory energy information label
that covers 19 products to date. However, the impact of these
programs and their savings potential has not been evaluated on
a consistent basis. This paper uses modeling to estimate the energy
saving and CO2 emission reduction potential
of the appliances standard and labeling program for products for
which standards are currently in place, under development or those
proposed for development in 2010 under three scenarios that differ
in the pace and stringency of MEPS development. In addition to
a baseline "Frozen Efficiency" scenario at 2009 MEPS
level, the "Continued Improvement Scenario" (CIS) reflects
the likely pace of post-2009 MEPS revisions, and the likely improvement
at each revision step. The "Best Practice Scenario"
(BPS) examined the potential of an achievement of international
best practice efficiency in broad commercial use today in 2014.
This paper concludes that under "CIS", cumulative electricity
consumption could be reduced by 9503 TWh, and annual CO2
emissions of energy used for all 37 products would be 16% lower
than in the frozen efficiency scenario. Under a "BPS"
scenario for a subset of products, cumulative electricity savings
would be 5450 TWh and annual CO2 emissions
reduction of energy used for 11 appliances would be 35% lower.』
