What You'll Learn
Set air conditioning to 25°C or higher
Setting your air conditioning to 25°C or higher is a simple yet effective way to save electricity at home in Singapore.
Firstly, it is important to recognise that every degree of cooling avoided will save you money on your energy bill. Therefore, setting your air conditioning to 25°C or higher will reduce your electricity costs. This is because the air conditioning unit will not need to work as hard to cool the room to a lower temperature.
Secondly, by increasing the temperature to 25°C or higher, you can lower your carbon emissions by 30%. This is because the air conditioning unit will not need to use as much energy to cool the room, and therefore will not produce as many greenhouse gas emissions.
Thirdly, setting your air conditioning to 25°C or higher can be more conducive to productivity. Researchers at the Singapore University of Social Sciences found that participants in an experiment had faster reaction times when the temperature was set at 25°C, compared to 21°C.
Finally, setting your air conditioning to 25°C or higher can be achieved alongside other energy-saving methods. For example, you can use a fan to spread cool air around the room more evenly, allowing for a higher thermostat setting. You can also use curtains or blinds to block out sunlight and reduce the amount of work your air conditioning unit needs to do to cool the room.
Therefore, setting your air conditioning to 25°C or higher is a simple and effective way to save electricity at home in Singapore, which can be achieved alongside other energy-saving methods.

Use energy-efficient appliances
In Singapore, where electricity prices are high, using energy-efficient appliances can significantly reduce your carbon footprint, utility bills, and energy consumption. Energy-efficient appliances are designed to deliver the same level of performance as their conventional counterparts while consuming less electricity.
One of the biggest culprits of high electricity consumption in Singapore is air conditioners. Given the hot and humid climate, air conditioners are essential for keeping homes cool and comfortable. However, running an air conditioner for extended periods can significantly increase your electricity bill. To reduce energy consumption, consider setting the temperature to at least 25°C when using air conditioning. Alternatively, opt for a fan instead of air conditioning, as suggested by EMA's energy-saving tips.
Another appliance that consumes a significant amount of electricity is the electric stove, especially if you frequently cook at home. To reduce energy usage, consider using small appliances like microwaves or slow cookers. Cooking with lids on pots and pans helps retain heat, and using the appropriate burner size for your cookware can also reduce energy consumption. Investing in an energy-efficient induction cooktop is another option, as they are often more energy-efficient than traditional electric stoves.
Yeobuild HomeStore in Singapore offers a wide range of energy-efficient appliances, including refrigerators, washing machines, dryers, and lighting fixtures. These appliances are designed to meet stringent energy efficiency standards, offering both performance and durability. They come with innovative features and advanced technologies, delivering superior performance while consuming less energy.
The Singapore government recognizes the importance of energy efficiency and provides various incentives to encourage its adoption. Consumers purchasing energy-efficient appliances may be eligible for grants or subsidies, making it more affordable to embrace a greener lifestyle.

Unplug devices when not in use
Unplugging devices that are not in use can help to save electricity and reduce the risk of electrical fires. This is because many devices continue to draw power when plugged in, even when turned off. This is known as 'phantom power use' or 'standby power'.
Small kitchen appliances, such as coffee makers, food processors, microwaves, toasters, and air fryers, are easy to unplug and can be dangerous if left plugged in due to their heating elements. Entertainment devices, such as televisions and video game consoles, also draw power through their blinking lights and indicators. Device chargers should also be unplugged when not in use, as they use electricity even when something isn't actively charging. Computers should be unplugged during storms, as power surges can damage them.
However, unplugging everything may not be practical, especially for larger appliances like your dishwasher, oven, refrigerator, and garbage disposal, which are more difficult to unplug. In addition, constantly plugging and unplugging devices with clocks may not be worth the effort, as the economic argument for unplugging has weakened in recent years. Instead, a power strip with an off switch can be used for low-load devices.
Overall, while unplugging devices may not save a significant amount of money, it can still help to reduce electricity consumption and improve safety.

Wash clothes in full loads
When it comes to saving electricity at home, one of the major consumers of energy is the laundry room. Washers and dryers can account for about 10% of total energy use in your home. Therefore, making conscious decisions about your laundry routine can help you save a significant amount of electricity and money.
One of the most effective ways to save electricity when doing laundry is to wash your clothes in full loads. Washing machines use the same amount of energy each time they are loaded, regardless of the number of items being washed. Therefore, washing one towel or ten towels will consume the same amount of energy. By waiting until you have a full load, you can reduce the number of times you run your washing machine, which will significantly reduce your electricity consumption.
Additionally, when it comes to drying your clothes, it is advisable to use the dryer only for full loads. Similar to washing machines, dryers use a similar amount of energy regardless of the load size. However, if your dryer has an auto-sensor, this advice may not be as applicable.
To further optimise your laundry routine and save electricity, consider the following tips:
- Rewear your clothes when possible to reduce the frequency of washing.
- Wash your clothes during off-peak hours, typically early in the morning or late at night, to take advantage of lower electricity rates.
- Use cold water instead of hot water whenever possible, as water heating accounts for about 90% of the energy used by a clothes washer.
- Opt for air-drying your clothes instead of using a dryer. If air drying is not an option, consider using a heat pump dryer, which is the most energy-efficient type of dryer.

Use a fan instead of air conditioning
Singapore's hot and humid weather makes it difficult to get through the day without air conditioning. However, air conditioners typically consume a lot of electricity, especially when they are working overtime to cool a room that is exposed to direct sunlight.
A simple way to reduce electricity usage is to use a fan instead of air conditioning. Fans consume far less electricity than air conditioners, making them a great money-saving option for days that are not too hot. For example, a typical air conditioner running on a high cool mode can consume around 1200 watts, while a normal fan consumes only about 150 watts.
To stay cool and save energy, you can use a hybrid cooling method by setting your air conditioner to a higher temperature than usual and turning on a fan. This method was piloted at an office space in the Zero Energy Plus Building at the BCA Academy in Singapore, and it was found that the occupants' comfort levels were similar to when the office was cooled to a lower temperature without fans. This hybrid method used 30% less energy compared to using just air conditioning.
Additionally, you can use a fan before turning on the air conditioner to help drive hot air outside and quickly bring down the temperature of the room. This will reduce the load on the air conditioner's compressor, saving electricity.
Finally, you can switch off the air conditioner after the room has reached a comfortable temperature and continue using a fan to maintain the cool temperature. This will help keep your electricity bill low even during hot summer days.
