Once upon a time, Sarah was hit with an astronomical electricity bill. She couldn’t believe her eyes!

Determined to uncover the truth, she embarked on a mission to find the top culprits of high electricity usage by appliance in her home. Little did she know, she’d soon uncover the 10 most notorious energy-guzzling appliances lurking in plain sight.

Don’t Let These Appliances Run Rampant in Your Home

If you’re like Sarah, you want to take control of your energy consumption and slash those power bills. In this article, we’ll unveil the top 10 culprits of high electricity usage by appliance, so you can put a stop to their energy-thieving ways. We’ve compiled this list using credible sources like Eskom and City Power, ensuring our information is tailored to the South African market.

1. Air Conditioners and Heaters

It’s no surprise that air conditioners and heaters top the list. These appliances are notorious for their high energy consumption, especially during extreme weather conditions.

  • Use energy-efficient models with good Energy Star ratings
  • Set a reasonable temperature – every degree higher or lower can impact consumption
  • Regularly maintain your unit to ensure optimal efficiency

2. Water Heaters

Heating water for bathing, washing, and cleaning consumes a lot of electricity.

  • Switch to a solar water heater to reduce reliance on the grid
  • Use a geyser blanket to insulate your water heater and conserve heat
  • Set the thermostat to 60°C, as advised by Eskom

3. Refrigerators and Freezers

These always-on appliances work around the clock to keep your food fresh.

  • Opt for newer, energy-efficient models
  • Set the right temperature (3-5°C for fridges, -15 to -18°C for freezers)
  • Regularly defrost your freezer and check the door seals

4. Ovens and Stoves

Cooking appliances, particularly ovens, can be major power guzzlers.

  • Use a microwave or slow cooker for energy-efficient meal prep
  • Opt for an induction stove, which uses less energy than conventional models
  • Use residual heat to finish cooking, by turning off the oven a few minutes early

5. Washing Machines

Your washing machine can be a sneaky energy thief, especially if you’re using hot water.

  • Use cold water for washing to save on heating costs
  • Choose a front loader, which uses less water and energy than top-loaders
  • Only run full loads and utilise energy-saving settings

6. Tumble Dryers

Tumble dryers are infamous for their electricity consumption, especially in winter.

  • Opt for a gas-powered or heat pump dryer for better efficiency
  • Line-dry your clothes when possible, especially in South Africa’s sunny climate
  • Keep the lint filter clean to ensure maximum efficiency

7. Dishwashers

Dishwashers can be more energy-efficient than hand-washing, but older models can still rack up a hefty electricity bill.

  • Choose an energy-efficient model with a high Energy Star rating
  • Only run full loads and use eco-friendly settings
  • Don’t use the heated drying option – air-drying dishes will save energy

8. Swimming Pool Pumps

Swimming pools are a luxury in South Africa, but their pumps can be a significant energy drain.

  • Invest in a variable speed pool pump, which can adjust its energy usage according to demand
  • Run the pump during off-peak hours to save on electricity costs
  • Regularly clean the filter and maintain the pool to reduce pump strain

9. Computers and Gaming Consoles

Your tech gadgets may be small, but they can greatly impact your energy usage.

  • Turn off computers and gaming consoles when not in use
  • Use energy-saving settings, like sleep mode or power saver mode
  • Opt for energy-efficient laptops over desktops

10. Televisions

Modern TVs, with huge screens, can consume a surprising amount of electricity.

  • Choose an energy-efficient model with a high Energy Star rating
  • Turn off the TV when not in use, rather than leaving it on standby mode
  • Adjust screen brightness settings to reduce power consumption

Keep the Culprits in Check

Now that you know the top 10 culprits of high electricity usage by appliance, you can make informed decisions to manage your energy consumption and save money. By choosing energy-efficient models, optimising appliance settings, and following best practices, you can take control of your power bills and create a more sustainable home.

Remember, knowledge is power, and in this case, it’s also the key to using less power! Follow in Sarah’s footsteps and keep an eye on your energy-guzzling appliances.

Frequently Asked Questions

What electrical appliance uses the most electricity?

Air conditioners and heaters generally use the most electricity, followed by water heaters and large appliances like refrigerators, ovens, and washing machines.

Can you measure electricity usage by an appliance?

Yes, you can measure electricity usage with an energy monitor or a plug-in power meter, which displays real-time consumption and calculates costs.

How much power do typical appliances use?

Power usage varies by appliance type, age, and efficiency. For example, an energy-efficient refrigerator may use 100-200 kWh per year, while an older model could consume 800-900 kWh.

How do I calculate how much power my appliance uses?

To calculate power usage, multiply the appliance’s wattage by the number of hours it’s used per day. Then divide by 1,000 to convert to kilowatt-hours (kWh).

Do appliances use electricity when plugged in but turned off?

Yes, some appliances still consume “standby” or “phantom” power when plugged in and turned off. Unplugging devices or using smart power strips can help reduce this waste.

What three appliances use the most energy in your house?

Typically, the three appliances that use the most energy are air conditioners/heaters, water heaters, and refrigerators.

How many kWh per day is normal?

Daily kWh usage varies depending on household size, location, and energy efficiency. In South Africa, the average household consumes around 30 kWh per day.

How many kWh does a 2000 sq ft house use?

Energy usage varies by location, insulation, and appliance efficiency. A rough estimate for a 2000 sq ft house in South Africa might be 20-30 kWh per day, but individual usage can differ significantly.

How much electricity does a fridge use per day?

A modern, energy-efficient fridge can use around 1-2 kWh per day, while an older model might consume 2-4 kWh.
