Energy Measurements

When calculating energy usage, it is calculated in units as Kilo Watt Hours or kWh for short and there is 1000 watts in a kilo-Watt kW. If you have a 1 kW appliance and it is plugged in for 1 hour, then you will use 1000 watts or 1 kWh. So when you are choosing appliances in your home, be aware that for example a 3 kWh appliance will use 3 times more energy than a 1 kWh appliance.

10 Tips to reduce you energy consumption

  1. Use high energy consumption appliances in off peak times
  2. Instead of cleaning all the dishes etc in the dishwasher, perhaps clean the glasses by hand which tend to be easier and so the dishwasher load is slower to fill up which means less washing cycles. Also avoid using it for half full loads.
  3. Choose A+ energy star rated appliances and wash you clothes in the washing machine at a lower temperature
  4. Reduce the number of times you use appliances that heat up quickly such as kettles, hair dryers, electric showers and tumble dryers
  5. Get an electricity smart meter installed so you can use your appliances at different times of the day and sign up for a smart electricity tariff
  6. Get into the habit of turning off appliance devices completely instead on leaving them on standby
  7. Use a single lamp light in the corner of a room rather than using a multiple light chandelier
  8. Shop around for a cheaper electricity supplier who tend to offer discounts for you to sign up with them and start looking at installing solar panels on your roof to heat your water
  9. When using electric showers, cut down on the amount of time you spend in the shower and using the lower power and heat settings plus reduce the hair dryer times to allow more natural air drying
