Achieving Up to 10% Energy Reduction:
A Guide for South African Households

6. Optimize Air Conditioning Use
If you use an air conditioner, set the temperature between 18 and 22 degrees Celsius, known as the “golden zone” for energy efficiency. Always keep doors and windows closed while using the air conditioner. On cooler days, opt for warm clothing or a blanket instead of turning up the heat.
7. Make Small Adjustments to Stay Warm
In colder months, simple actions like closing curtains at night, using gas heaters instead of electric ones, and employing hot water bottles can make a big difference. Draft excluders placed at the bottom of doors can also help by keeping warmth in and cold air out.
8. Engage the Whole Family
Energy conservation is a team effort. Sit down with your family to assess where everyone can make changes to reduce energy consumption. The average household uses around 1,100 kWh per month, and small adjustments—like switching off appliances at the plug when not in use—can lead to significant savings.
By following these tips, you’ll not only reduce your household’s energy consumption by up to 10%, but also help ease the pressure on the country’s energy infrastructure and save money on your utility bills.
Reducing energy consumption by just 10% in every household can significantly relieve the pressure on South Africa’s aging infrastructure and ease the load on Eskom. Not only would this help alleviate strain on the power grid, but it would also result in noticeable savings on monthly energy bills. Here are some practical tips to help you reduce your household’s energy consumption by up to 10%.
1. Become More Energy Conscious
The first step toward reducing energy costs is simply becoming aware of energy usage. Small issues, like a dripping tap, can add up to as much as R600 a year if not addressed. Fix leaks promptly to avoid unnecessary costs. Your geyser accounts for approximately 39% of your monthly energy consumption. Consider installing a timer to automatically switch it off at set times. Insulating your geyser and exposed piping can also cut down on energy loss and lower costs further.
2. Shower More, Bath Less
Switching from baths to showers not only conserves water but also reduces the amount of hot water your geyser needs to heat, lowering your energy usage. Opt for an energy-efficient showerhead to further decrease both water and heating costs.
3. Use Energy-Efficient Lighting
Next time you do your shopping, invest in Compact Fluorescent Lamps (CFLs) for your home. While the initial cost may be higher than regular incandescent bulbs, CFLs produce minimal heat and are much more energy-efficient, providing light without wasting electricity on heat production.
4. Turn Off Appliances Completely
Many people believe turning off appliances like TVs before bed is enough, but appliances left on standby can still consume up to 50% of their normal power usage. It’s better to switch them off at the wall socket. Remember to unplug devices like cell phone chargers once they’ve done their job, as they continue to draw power even when not in use.
5. Maintain Your Refrigerator
A well-maintained refrigerator is crucial for energy efficiency. Keep the seals on your fridge and freezer clean and in good condition—if they deteriorate, cold air escapes, causing the unit to use more energy to maintain its temperature.
