What costs make up my electricity bill?

Every household is different, however there are common themes that occur in most households regarding energy consumption. Acknolwedging which electrical appliances use the most electricity and also understanding even basic energy-saving tips, can have a positive impact in terms of a lower electricity bill.

This is the breakdown of energy usage in a typical household.


Lights use more than anything in a typical household, so why not switch to energy saving lightbulbs and remember to turn off lights when you leave a room? Also, educating other family members, particularly children, on the need to switch off lights and any electrical appliances they have finished using, will help to reduce your electricity consumption.
