The team at Power Saving Centre Canberra understands the importance of reducing our carbon footprint and improving energy efficiency in our daily lives. To increase the energy efficiency of your home and hence reduce your energy usage, appliances with particular attributes should be chosen. The table below shows an example of the relative energy usage for high energy-consuming household appliances.
When choosing household appliances, it is important to have an understanding of how efficiently the appliance will consume energy, as well as simple methods that you can use to further reduce daily energy consumption. The following information describes important features to be aware of when choosing and using common household appliances.
There are a number of factors that are important in selecting an efficient oven. A fan-forced oven will circulate hot air evenly, cooking food quicker and hence using less energy than conventional ovens. Ovens with triple glazed doors as well as high standards of insulation will retain heat better, reducing heat losses and thus improving efficiency. Additionally, methods of use for the oven can be implemented to reduce energy use, such as; keeping the oven door closed (reducing heat escape), cooking several dishes in the oven at once, turning the oven off early and using the remaining heat to complete the process, using fan forced, regularly checking and maintain seals, and using alternate smaller kitchen appliances such as microwaves where possible. Additionally, self-cleaning ovens typically have more insulation than standard ovens, therefore reducing heat losses.
While no particular models of wall-mounted ovens can be recommended as energy efficiency is not commonly listed for ovens, an oven with the following properties should provide optimal energy efficiency (primarily through reducing heat losses):
* Fan forced
* Triple glazed doors
The following passive methods of energy efficiency can also be applied:
* Keep oven door closed
* Cook in bulk when possible
* Turning oven off early to use residual heat
* Regularly check seals
* Use alternate kitchen appliances when possible
In choosing a highly energy efficient washing machine there are several attributes to look for. The following washing machine attributes will maximise energy efficiency:
* A star energy rating of at least 3.5, the higher the better, with a max of 6 stars. Every star can save 25% of the washing machine’s energy use on a warm cycle.
* A cold water wash cycle which can reduce energy use by up to 80% when used.
* Hot and cold water connections, allowing the washing machine to import hot water from the heater (provided by the solar water heater in this case) rather than heating it in the washing machine. Since 80-90% of the energy used by a washing machine goes towards heating the water, this will reduce energy consumption significantly, similarly if cold wash cycles are used.
There are also a few passive methods of reducing energy usage, such as washing on a cold wash cycling as often as possible and using the washing machine only when there is a full load of clothing.
Maximising energy efficiency of a dishwasher is very similar to a washing machine. As such, dishwashers with the following attributes should be chosen to maximise efficiency:
* At least a 3.5 star energy rating
* Dual hot and water connections
Additionally, only using the dishwasher when there is a full load of dishes helps to reduce energy usage.
