Energy Efficient Appliances


Energy efficiency appliances can help us reduce the amount of energy we need to get the same or better level of service.

Clear labelling on appliances will alert us how much energy will be required to run the appliance, as well as how much energy was used to create it, and will be needed to maintain it, and eventually recycle or dispose of it.

Regulations that gradually life minimum energy efficiency standards, will encourage appliance manufacturers to invest in energy efficiency innovation.


Energy Performance Standards

Technical requirements for MEPS are set out in the relevant appliance standard, which is referenced in state regulations. State based legislation is necessary because the Australian constitution gives Australian States clear responsibility for resource management issues, including energy.

Heating Appliances

Electric resistance heating converts nearly 100% of the energy in the electricity to heat. However, most electricity is produced from oil, gas, or coal generators that convert only about 30% of the fuel's energy into electricity. Because of electricity generation and transmission losses, electric heat is often more expensive than heat produced in the home or business using combustion appliances, such as natural gas, propane, and oil furnaces.

If electricity is the only choice, heat pumps are preferable in most climates, as they easily cut electricity use by 50% when compared with electric resistance heating.

Energy Efficient Appliance Regulations

[The Queensland Government has updated energy and water savings standards] for new homes. Greenhouse efficient hot water systems, energy efficient lighting, dual-flush toilets and water pressure devices will be compulsory from next year. Electric hot water systems will be banned next year.

Builders say these measures will limit the choices available for buyers. Tony Rider from Masterbuilders: "The impact of banning electrical hot water systems in new homes is almost negligible - no more than 0.04 per cent per year. However, the cost of installing a basic solar hot water system is double the price of electric, so it is the consumer that's going to suffer here."

But [conservationists say the standards] benefit everyone. "This new code is a win-win for new home owners. If you install greenhouse efficient hot water systems, you will reduce your energy bill by as much as 40 per cent." (Toby Hutcheon, Queensland Conservation Council.)

Queensland's Environment Minister Desley Boyle says there will not be any subsidies offered to help with the cost of compulsory energy and water saving measures for new homes. Ms Boyle admits the new laws will make building a home more expensive. "Yes it will initially increase the price of a new house by as much as $1,000 to $2,000. But mandating all of these devices will bring the price down as developers buy in bulk."

Mr Hutcheon says the next question should be how to improve the efficiency of existing houses. "The New South Wales Government have got a system right now that encourages people when they're renovating to actually put in water and energy efficient appliances."
