Energy-Saving Tips That Actually Work in Singapore

The average Singapore household spends SGD $180–$250 per month on electricity. With aircon accounting for roughly 40% of that, there's significant room to save — without suffering through the heat. Here are eight tips that make a real difference.

1. Set Your Aircon to 25°C, Not 18°C

Every degree below 25°C increases energy consumption by approximately 8–10%. The difference between 18°C and 25°C isn't comfort — it's your electricity bill. Most people sleep just fine at 24–25°C with a fan on.

2. Use the Timer Function

Turn your aircon off 30 minutes before you wake up or before your usual wake-up time. The room stays cool enough, and you save the energy of that final half-hour cycle.

3. Service Your Aircon Regularly

A dirty filter forces your aircon to work 20–30% harder to achieve the same cooling effect. Regular servicing (every 3 months) pays for itself in electricity savings.

4. Switch to LED Lighting Throughout

LED bulbs use 75% less energy than traditional incandescent bulbs and last 25 times longer. If your condo or HDB still has fluorescent tube lighting, replacing them with LED is one of the fastest payback investments you can make.

5. Unplug Appliances at Standby

Standby power can account for 10% of your total electricity usage. Your TV, microwave, and desktop computer use power even when switched "off" at the device. Use smart extension strips to cut power completely.

6. Wash Clothes in Cold Water

90% of washing machine energy goes to heating water. Modern detergents work perfectly in cold water for normal loads. Make this switch and you'll notice the difference in your bill within one month.
