Electricity

The generation of electricity is the largest producer of Green House Gasses worldwide with just under 25% of global emissions resulting from electricity generation.

In Australia the share is even greater with 35% if all Green House Gas emissions resulting from electricity generation. This is due in part to our higher than average electricity consumption and in part because we use a lot of coal fired power stations.

In Queensland 88% of electricity is generated in coal fired power stations accounting for 95% of the electricity related GHG emissions).

On the Sunshine Coast the average household uses 2,100 kWh a quarter (at a cost of $435 and 1,848 kg CO2). Electric hot water systems are the largest single users of power in the home followed by fridges and other whitegoods.

Energy use profile for an average Sunshine Coast household (2,104 kWh/Qrt):

Carbon emissions from electricity are among the key sources of carbon emissions for a household. For example the average Australian car produces about 3,900 kg of CO2 a year compared to 1,848 kg of CO2 from electricity. For a more comprehensive comparison of the Green House Gas emissions from different activities check out the ACF Consumption Atlas.

The amount of electricity used in a household is highly dependent on the type of appliances and the way they are used. Poolpumps for example are a major consumer of electricity and households with a pool are likely to have energy bills as much as 25% higher than the average households. On the other hand households with solar hot water and a gas cooktop could be using as much as 75% less electricity. Click here for the energy profiles of different Sunshine Coast households.

Of course inefficient appliances have a higher financial cost as well as a higher environmental cost. The table below shows the energy consumption and quarterly operating cost (in CO2 and in $) for some common appliances.
