How to save electricity at home: become energy efficient

October 28, 2019

With increasing Eskom tariffs in South Africa, saving electricity has become the best way to put money back into your pocket. You can make your household less electricity-dependent by adopting smart energy routines around your home and installing energy-efficient equipment. Below is a series of tips to save 10 to 50% on your electricity bill! Click here to see Recommended Energy Saving Solutions.

Save 10% or more of energy

Geyser blanket
Fit your geyser with a geyser blanket. This will prevents heat loss and reduce the cost of electricity that is needed to keep the water hot.

Turn down your geyser temperature from 65°C to 55°C. 55°C is hot enough to block pathogens from spreading. Your geyser will require a lot less electricity to keep warm.

UV films on windows
Put UV films on your windows to keep the sun from heating your home too much in summer: you won't need to run your aircon so long and so often. Aircon is a real electricity guzzler in summer, often accounting for 20% or more of your electricity consumption during the hotter months.

Install roof awnings/ overhangs to shade windows. They provide shade for your windows and, like the UV films, prevent heat from entering your home in the summer.

Slow cooking
Bring food to the boil then place the hot pot in an insulation cooker, for the retained heat to slow cooks. Slow-cooking uses less energy than a traditional oven.

Run the dishwasher with full loads only and on eco mode. 

Washing machine on cold
Switch your FULL load of laundry from hot water to cold water. If you use cold water already, cut one load of washing per week.

LED lights
Replace incandescent light bulbs with energy-saving (LED) ones that use 6 times less electricity.

Sealing gaps
Seal or block gaps around doors and windows to prevent heat from escaping and cold drafts from breezing in during the winter months.

Use sunshine
Use sunshine whenever possible to dry your laundry, not the tumble dryer. For cold and rainy days, use drying racks indoors, near the fireplace.

Save 30% or more of energy

Adding a few affordable items (typically under R1000) can save you up to 30% or more:

Geyser timer
A geyser timer controls the amount of time the geyser runs for. By only heating water just before you need it (4-6am), heat loss to the environment is kept to a minimum.

Induction cooking uses about 30% less electricity than traditional electric stoves.

Pool pump timer
Set your pool pump to run fewer hours. A small pool pump easily uses 500 to 1000W (4 to 8 fridges). The pump should be set to push the entire content of your pool through the filters once a day. Calculate the size of your pool and compare to the flow of your pump: a 0.75kW pool pump pushing 20 cubic meters of water per hour only needs to run 2.5 hours a day for a pool of 50 cubic meters.

Short shower
Take a 5 to 10 minute shower instead of a bath. You can save up to 80% of water and use 5 times less electricity than heating a bath of water.

Install an energy and water-efficient shower head. These use up to 40% less hot water and will save you money on your electricity bill.

Make a real difference and save 50% or more of energy

Doing renovations to your house is a perfect opportunity to invest in some energy-efficient solutions that will save you electricity costs in the long term and add value to your property:

Double glazing
Double glazing your windows reduces heating and cooling losses from your windows by as much as 90%. It reduces noises too, and offers better protection against break-ins.

Roof insulation
Insulate your ceiling. It slows heat loss and makes your home up to 5°C warmer in winter and 5°C cooler in summer, saving you heating and aircon costs.

Closed fireplace
Light a fire instead of using electric heating. Closed combustion fireplaces retain heat and warm spaces effectively, keeping your costs down and the warmth up. They advantageously replace electric heaters.

Gas heater
Gas heaters are cost-effective, eco-friendly, efficient and reliable - especially during power outages. They are not as powerful as a closed fireplace though.

Gas geyser
Gas geysers are cheaper to run in the long term than electric heaters. Plus, they supply hot water immediately.

Solar geyser
Invest in a solar geyser and save drastically on your electricity bill.  

Gas cooking
Use gas for cooking instead of electricity. Gas is more efficient and you have the added advantage of still being able to cook during power outages.
