5 Ways to Save Electricity at Home
Electricity costs in Malaysia keep increasing, and many households are looking for simple ways to reduce their monthly TNB bill. The good news? You don’t need expensive gadgets to save power.
Here are the top 5 easy ways to save electricity at home, suitable for every Malaysian household in 2025.
1. Use Energy-Efficient Appliances
Appliances with a 4-star or 5-star energy efficiency rating consume less power compared to older models. If you plan to replace a fan, fridge, air-cond, or washing machine, always check the **Energy Efficiency Label**.
- Inverter air-conditioners save 30–40% electricity
- LED bulbs use up to 85% less power than normal bulbs
- Modern fridges with inverter compressors run more efficiently
2. Set Your Air-Cond Temperature to 24–26°C
Air-conditioning is the biggest contributor to high electricity usage in Malaysia. Setting your temperature to **24–26°C** helps reduce the load on your AC compressor.
Additional tips:
- Use fan + air-cond together so you can raise the temperature but still feel cool
- Service your air-cond every 6–12 months
- Close doors and windows to prevent cold air from escaping
3. Turn Off Appliances Completely (Not Standby Mode)
Many appliances still use electricity in standby mode. This includes TVs, routers, chargers, laptops, speakers, and microwave ovens.
- Use a power strip and switch everything off when not in use
- Unplug chargers when they’re not charging
- Disable “always on” smart features you don’t use
4. Maximise Natural Light During the Day
Malaysia has plenty of sunlight — use it. Open your curtains and windows during the day to reduce the need for artificial lighting.
- Use lighter curtains to brighten your space
- Place your study or work desk near a window
- Switch to LED lights for rooms you use at night
5. Reduce Water Heater Usage
Instant water heaters consume a lot of power, especially if used daily. Limiting your heater usage can reduce your electricity bill significantly.
- Set heater temperature lower
- Take shorter showers
- Use solar or energy-efficient heaters if possible
Bonus Tips to Lower Your TNB Bill
- Wash clothes with cold water whenever possible
- Iron clothes in batches to save power
- Clean your fan blades — dust reduces performance
- Switch off lights when leaving a room
- Use smart plugs to monitor your consumption
