By progressively increasing the energy efficiency of gas appliances and
equipment beyond business as usual levels, Switch on Gas responds to the
evolving needs of the community by providing world class energy-eficient
gas products. Switch on Gas will also make a contribution to national efforts
to reduce greenhouse gas emissions. Natural gas currently supplies about
30% of total household energy in Australia. Within 20 years it is projected
that Switch on Gas has the potential to reduce Australian consumers' expen-
ditures on natural gas by up to $115 million per annum and to reduce their
consumption by more than 5% below business as usual.
The Australian and New Zealand Equipment Energy Efficiency Program
released its inaugural work plan for Switch on Gas in April 2005, out-
lining products targeted for potential regulation in both countries for
the three-year period, 2005/06 to 2007/08. An updated version of this
work plan was released for comment in October 2006 (2006/12) and is a
consequence of
1. The administrative and regulatory basis of the gas appliance effi-
ciency programme
2. New information about gas appliance technology and testing
3. Gas consumer response to energy labels
4. Changes to the gas labelling and MEPS scheme for appliances
In 2002, the Sustainable Energy Authority of Victoria (SEAV) (now
Sustainability Victoria, or SV), the Victorian Office of Gas Safety (OGS),
and the Australian Greenhouse Office (AGO) commenced working together
to review the gas appliance labelling and MEPS scheme and to explore
