Australian Government To Phase Out Greenhouse Intensive Water Heaters
Heating water is one of the largest uses of energy in Australian households accounting for almost 22% of household greenhouse gas emissions in 2008.
Gas water heating accounts for almost half of the energy from water heating; however as electric resistance water heaters are by far the most greenhouse intensive water heaters they accounted for almost 80% of all water heater emissions. The average electric storage water heater emits about three times the amount of greenhouse gasses than other hot water systems such as gas, solar, or heat pump. For this reason the Australian Government aims to phase-out of greenhouse intensive water heaters.
The choice of a new water heater currently depends upon individual or household purchase decisions. This decision is usually rushed as water heaters are typically replaced when the system has failed and therefore limited time is available for research and selection. Financial restrictions often lead to the cheapest system being purchased regardless of its lifetime costs; therefore greenhouse intensive water heaters are often still being installed.
There are changes expected to occur in generation fuel mix expected to occur under the Carbon Pollution Reduction Scheme (CPRS) and the Renewable Energy Target (RET), however despite this electric storage water heating expected to remain the most greenhouse intensive for at least the next 30 years. While higher energy prices are expected once a Carbon Pollution Reduction Scheme (CPRS) has been introduced, and households would place greater consideration on running costs in the water heater replacement decision, it is still likely that market failures will occur and lead to greater emissions than would otherwise occur.
The proposal, prepared for the National Framework for Energy Efficiency, is to regulate against the installation of greenhouse intensive water heaters in houses. For more information about the proposed options visit - http://www.greenenergytrading.com.au/blog.html
Public consultation meetings will be held between 10 February and 19 February 2010 in Canberra, Sydney, Melbourne, Brisbane, Darwin, Perth and Adelaide.
