06 Jun Electricity: The big users
Our daily electricity consumption will largely be determined by our respective lifestyle choices – but what exactly is using up all that power? Well, for a start, it’s useful to remember that the biggest users of electricity are those items that draw on power for heating purposes, or cooling. In the home, these culprits of heavy drawing power will generally be electric stoves, clothes dryers, hot water boosters, and irons (heating) – and freezers/refrigerators, and air-conditioners (cooling). Our lifestyles will shape the usage of these items – including how often – and be reflected in our power bills.
Some appliances will vary in the amount of electricity they use. Washing machines for example, use more power when washing with hot water. Fridges and freezers, operate continuously but on cycles. They will draw more electricity when working to cool the space. Electrical use can also vary from model to model. So it will pay to remember that we can make savings by utilizing energy saving appliances, which are star-rated, as much as possible. Lighting and electronic equipment fall into the next range of power consumption, and there will also be variation in patterns of usage, which produce varying results. We’ll look at those next.
