Earth Hour 2025 is a powerful reminder of our collective responsibility to conserve energy and protect the environment. While switching off lights for an hour makes an impact, long-term energy-saving habits are what truly matter. In Singapore’s hot and humid climate, air conditioning is essential, but it can also be a major contributor to energy consumption. With the right strategies, you can keep your home cool while reducing electricity usage and your carbon footprint.
Choose the right temperature setting
Setting your aircon at the ideal temperature is one of the easiest ways to save energy. In Singapore, the National Environment Agency (NEA) recommends keeping it at 25°C. This strikes a balance between comfort and efficiency, ensuring that your unit doesn’t overwork. Every degree lower can increase energy consumption by up to 10%, so avoid setting it too low. If you still feel warm, using a fan alongside your aircon can help improve circulation without excessive energy use.
Maintain your aircon regularly
A well-maintained air conditioning unit operates more efficiently and consumes less power. Dirty filters and clogged coils force the system to work harder, increasing electricity consumption. Scheduling regular aircon servicing helps to keep your unit in top condition. Professionals will clean filters, check refrigerant levels, and inspect components to ensure everything functions optimally. If your aircon is not cooling effectively, it could be due to low refrigerant levels, in which case an aircon gas top-up in Singapore might be necessary.
Invest in an energy-efficient aircon
If your aircon is over ten years old, it might be time for an upgrade. Newer models with higher energy efficiency ratings consume significantly less power while providing the same level of cooling. Look for units with the NEA’s Energy Label and choose models with at least five ticks. Inverter air conditioners are another great option as they regulate power usage based on cooling needs, reducing energy waste.
Use smart cooling techniques
Reducing heat build-up in your home means your aircon won’t have to work as hard. Keep curtains or blinds closed during the day to block out direct sunlight. If possible, install heat-reflective window films to reduce indoor temperatures. At night, take advantage of cooler outdoor air by using natural ventilation or ceiling fans instead of air conditioning.
Avoid overworking your aircon
Small habits can make a big difference in prolonging your aircon’s lifespan and reducing electricity consumption. Close doors and windows when the aircon is running to prevent cool air from escaping. Avoid placing heat-generating appliances, like lamps or TVs, near the aircon’s thermostat, as this can cause the system to overcompensate. Using the sleep mode function at night can also help save energy by gradually increasing the temperature while you sleep.
