Almost everything we do uses energy. Nearly everything we own needed electricity to be created. We may not readily consider it but we have a huge dependency on energy. Despite its major role in our day to day lives it's vital that we use our energy resources efficiently as there are negative environmental impacts associated with electricity generation. Currently over 90% of energy generated in New South Wales comes from coal-fired power stations. The coal that is burnt to create this energy is millions of years old, is a non-renewable resource and emits carbon dioxide into the atmosphere as it burns.
We are all aware of the increasing costs of electricity and this is anticipated to continue in the future. Using energy efficiently is a good way to reduce your electricity bills and as a bonus, you will be reducing your carbon footprint as well.
Where energy is used in the home

Heating and Cooling
Appliances and equipment including refrigeration and cooking
Generally one of the bigger household energy uses are heating and cooling the home, heating water and powering appliances . Below are some tips to be more energy efficient:
- Setting the temperature at 18 - 21 degrees in winter and 23 - 26 degrees in summer, by doing this you can lower your running cost by up to 10%
- Only heat or cool the rooms you use

It's important that we continue to research the use of alternative energy sources and purchase cleaner energy where possible. Alternatives to the traditional coal-fired power plant consider the use of renewable resources to create energy which means these resources will never run out. Examples include solar (sun), wind, tidal, wave, geo-thermal and biomass.
