Wise Ways to Reduce Electricity Consumption

By using energy wisely, you’ll help to keep your monthly utility costs down – this is called demand-side management. In addition to the cost implications, the growing population and accompanying demands on our energy resources have a severe impact on the country’s natural resources.
Every kilowatt hour of electricity saved also results in one less kilogram of carbon dioxide emitted by a power station, which benefits our environment at the same time.

We have listed our useful power-cutting tips below in sections for your easy reference.


  • Switch off the lights when they are not needed.
  • Use fewer bulbs with higher wattages. For instance, one 100 wattbulb produces the same light as two 60 watt bulbs. 
  • Dimming switches reduce electricity consumption. 
  • Use compact fluorescent lamps (CFL) instead of ordinary bulbs. 
  • Use low-energy lamps for exterior lighting.
  • Paint the walls of your home in a light colour. Dark colours tendto absorb light, requiring you to use more energy from lightbulbs to achieve the same effect.
  • Set your electrical geyser’s thermostat at 55 ° C to 60 ° C. To saveenergy, make sure the geyser and all hot water steel pipes in theroof are well insulated with fibreglass or newspaper.

  • Use the correct heaters. Infrared electricity heaters are the mostenergy efficient heaters available while oil heaters are the safest. 
  • Insulate the ceiling and seal air gaps in the home. Ensure thatheaters have thermostats. 
  • Use electric blankets but turn them off when in bed.

  • Use pressure cookers when preparing food that takes a long time to cook.
  • Match pots and pans to stove plates. Small pots on large plates waste electricity. 
  • Do not use pots with distorted bottoms. 
  • Switch off the plates or oven before food is fully cooked. This allows you to finish your cooking without using energy.
  • Keep oven doors closed until food is cooked.
  • Do not preheat the oven. It isn’t necessary to preheat the oven except for food requiring high temperatures and slow cooking times.
  • Make use of the oven’s leftover heat. Your oven retains heat for15 to 30 minutes after it is turned off.
  • Use that free heat to warm up desserts, rolls or freshen crackers and cookies.
  • Glass and ceramic pans retain heat better than metal pans.
  • Don’t open the fridge door unnecessarily and make sure the seal is intact.

Cold Storage – Refrigerators & Freezers

  • Don’t open the door unnecessarily and make sure the seal is intact. 
  • Turn off an empty refrigerator when going on holiday. 
  • Let hot foods cool down before placing them in the refrigerator. 
  • Defrost fridges regularly. A build-up of ice reduces operating efficiency and increases running costs.
  • Defrost the freezer regularly. Freezers work harder to remove heat and have to use more power. Only 90% of a freezer’s capacity should be used for freezing.

Microwave Ovens

  • When you defrost food, leave it in the fridge overnight. You’ll use less electricity than defrosting food in the microwave.
  • Use the microwave to cook small to medium quantities of food. For larger portions of meat, it’s better to use a conventional oven or pressure cooker.

Other Appliances

  • Do not buy larger or more powerful appliances than are actually required.
  • Do not buy an electric appliance when a hand-operated one will suffice.
  • Use the correct appliance for the job e.g. do not make toast on the stove or in the oven.
  • Do not fill a kettle if only a small quantity of boiling water is required. It is sufficient to put in only enough water to cover the element.
  • You can avoid ironing clothes by removing clothing promptly from tumble dryer and folding them carefully.
  • It is more economical to boil water in a kettle rather than in a pot on the stove.
  • Operate swimming pool filter pumps for minimum periods.
