Smart Tips to Conserve Energy and Save More This Festive Season

With only a few days left until Raya, many are busy preparing Raya treats or getting ready to head back to their hometown.  Your electricity bill may also increase during the festive season because ovens, electric kettles, and refrigerators – which are some of the most crucial electrical appliances during the festive season – consume a lot of energy.

You can breathe a sigh of relief when it comes to lights, as they don’t consume much energy. This allows you to leave some of the lights on when you’re away. That said, it’s highly recommended to change your electrical equipment to energy-saving ones, especially if such equipment is getting old.

Nowadays, electrical appliances come with energy-saving elements, such as inverter technology. Such equipment consumes about 30-40% lesser energy than those using conventional technology. It is ideal especially for cooling appliances such as the fridge and air conditioner.

If you can’t afford new electrical appliances at the moment, start with small steps. Find out where wastages are happening, and figure out ways to cut cost.

Conserve energy and save more this Raya by following these simple tips:

1. When baking or cooking

It won’t be a complete Raya celebration without a little baking or cooking. Whatever Raya treats you decide to make, make sure you follow these tips to cut cost:

Using ovens

  • Make good use of the oven’s multiple racks
    Your oven probably has multiple racks that consist of top rack, middle rack, and bottom rack. Instead of only using a rack, fill all three racks with your treats for efficient use. Each rack also serves a different purpose. The top rack is meant for high-temperature and quick cooking. The middle rack is best for moderate temperature cooking, while the bottom rack is for slow cooking and low temperatures.
  • Avoid opening the oven door too often
    You’ll lose a disproportionate amount of heat (approximately 25 degrees) every time you open the oven door. It’s better to rely on the oven light, timer, and the smell to find out if your food is ready.
  • Calibrate your oven
    To ensure the oven’s temperature setting is accurate, get an inexpensive thermometer to calibrate your oven. Cooking at the right temperature will not only ensure the food is baked properly, but it will also save your money if the oven is set high.

Using electric stoves

  • Cover up your pots and pans
    Get the food to cook more quickly without turning up the stove while generating a higher temperature by covering the pots and pans.
  • Turn off the stove a minute or two earlier
    An electric stove can still run at a high temperature even after a minute or two of being turned off. You can turn off the stove when the food is almost cooked and leave it for a few minutes.

Leaving some of the lights on is probably the norm if you’re away from home. Many of us do this to prevent a possible break-in. With the lights on, at least it will appear as if there’s someone at home.

Though lights do not consume a lot of energy and form only about 20% of household electricity usage, it can still contribute to the increase in your electricity bill if you aren’t careful. Here are some tips to save more on lighting cost:

  • Use energy-saving light bulbs
    These types of bulbs consume less energy and last longer, which is perfect if you want to leave the lights on for a few days.
  • Use outdoor light timers to prevent excessive energy usage
    Instead of leaving your outdoor lights on all day long, install a timer to keep them on, only when they need to be.  
  • Save more while adding brightness using T5 fluorescent lights
    Want your home to be so bright it chases potential burglars away? Use slimmer fluorescent lights such as the T5 variants, which add brightness while consuming less energy.
  • Use spotlights with motion sensors
    Another thing that could potentially prevent your house from burglary is a spotlight that comes with a motion sensor, which helps in saving energy as they only light up when there’s a movement detected. You can install a few of them at the darkest, most isolated corners of your home, outdoor or indoor.

3. During an open house

For those having an open house, the air conditioner or fan is important to ensure the guests’ comfort. However, leaving them on for too long will cost you a lot.

During an open house, you’ll probably rely on kettles to make drinks as well. Find out how to cut cost on these appliances and conserve energy:

  • Remember to clean your AC filter to allow more cool air to flow out.
  • Close your windows and doors while the AC is running to cool the room faster.
  • Set your AC between 23-25℃ for optimum coolness while keeping your energy consumption low.
  • Instead of leaving the AC running all day long, set a timer and switch it off when there aren’t many people in the house.


  • When boiling water, fill the kettle to the maximum level. Save the remaining water in a flask so you don’t need to boil it again.
  • Clean the limescale on your kettle regularly.

4. Calculate electricity cost

Hours of usage, number and age of electrical appliances, living habits, and your family size are the factors that determine the electricity consumption cost.

You can calculate the estimated electricity cost for different appliances using the following formula: Electricity Consumption (kWh) = Power (watts) x Hours of Operation x 30 days ÷ 1000.

TNB provides a good example of the estimated usage cost for appliances like lighting, refrigerators, or rice cooker in detail. Check out the table here.

Electricity tariffs go up when you use more power. These are the rates per kilowatt hour:

  • For the first 200 kWh (1-200 kWh): 21.8 sen
  • For the next 100 kWh (201-300 kWh): 33.4 sen
  • For the next 300 kWh (301-600 kWh): 51.6 sen
  • For the next 300 kWh (601-900 kWh): 54.6 sen
  • For the next kWh (901 kWh onwards): 57.1 sen
