What You'll Learn
Use energy-efficient appliances
In Malaysia, electricity rates are rising due to increasing international energy demand, supply chain disruptions, and the shortage of natural resources. As such, it is important to consider ways to save electricity at home, such as by using energy-efficient appliances.
Energy-efficient appliances are designed to reduce utility costs and protect the environment. For example, a 5-star refrigerator consumes around 43% less energy than a 2-star model, saving you up to RM62 annually. Similarly, modern energy-efficient refrigerators are available to replace old or neglected ones that waste power. LED or compact fluorescent bulbs are also a cost-effective alternative to traditional bulbs, which waste energy by converting most of it to heat.
In the kitchen, water-efficient equipment like energy-efficient dishwashers use less water without compromising washing capability. They may include water-saving fixtures like aerator nozzles for taps or recycling water functions. Additionally, choosing a good water heater can help you save energy. These appliances use a lot of electricity, especially in Malaysia's tropical weather, where hot showers are a must for many households.
The initial cost of buying energy-efficient equipment may be higher, but it will reduce your long-term electricity costs. To promote the purchase of energy-efficient appliances, Malaysia's SEDA (Sustainability Energy Development Authority) launched the SAVE (Sustainability Achieved via Energy Efficiency) 4.0 programme in December 2023, offering up to RM400 in e-rebates for buying certified energy-efficient appliances.

Reduce air conditioning usage
Malaysia's hot climate means that many people use air conditioning to stay cool, but this can result in high electricity bills and increased energy consumption. Here are some ways to reduce air conditioning usage and save electricity at home:
Firstly, check if your air conditioner is energy efficient. Look for the EER sticker and the number of stars, which indicate its efficiency rating. If your unit is not efficient, consider replacing it with an inverter AC, which offers reduced energy consumption and environmentally friendly refrigerants.
To reduce electricity usage, regularly clean your air conditioner's filter, ideally once every three weeks. A clogged filter means the unit has to work harder to push cool air out, increasing energy usage. Keeping your unit well-maintained will also help avoid leaks or faults that can cause damage.
When using your air conditioner, set the temperature between 23-25 degrees Celsius. This is the optimal temperature range for energy savings and allows the unit to run at its best performance without overworking. Additionally, use the "Dry mode" instead of "Cool mode" to reduce humidity and automatically lower the room temperature.
To avoid unnecessary air conditioning usage, try to keep direct sunlight out of your room. Use thick curtains, blinds, or tinted windows to block the sun and keep the room cooler. Open windows at night or in the early morning to let in cooler air, and only switch on the air conditioning when needed.
Finally, use the timer function on your air conditioner to set it to turn off after a few hours. This is especially useful at night, as you likely don't need the air conditioning running all night. Combining the timer with a ceiling fan can help maintain a comfortable temperature while saving electricity.

Fix water leaks and use cold water
Water leaks can cause a lot of damage to your home, and they can be costly to fix. Leaks can cause your electrical wires to corrode, and in turn, promote mould growth. This can then lead to electrical short circuits or even start a fire. Water leaks can also cause your ceiling to become soaked and lose its structural integrity, which can be extremely dangerous.
To prevent this, you should fix any water leaks as soon as possible. If you are unable to locate the source of the leak, consider consulting a licensed plumber. In some places, there are programs that provide financial relief for leak repairs, such as the Leak Forgiveness Program in New York.
Another way to save electricity is to use cold water instead of hot water when doing laundry. It is estimated that 75% to 90% of the energy used by a washing machine goes towards heating the water. By switching to cold water, you can save energy and money, and even help your clothes last longer. Cold water is also effective at removing stains and particulate matter, such as dried skin flakes.
If you are concerned about killing bacteria, you can use warm water for the rinse cycle. This will still save you money compared to using hot water, and it will help remove any excess soap left in your clothes.
In addition to saving electricity, using cold water can also help reduce greenhouse gases and your carbon footprint.

Install solar panels
Solar panels are a great way to reduce your electricity bills and embrace sustainable living. Installing solar panels can be an effective way to generate your own electricity and even sell any excess back to the grid or utility company.
Solar installations are sized in kilowatts (kW) and the size of the installation will depend on your consumption, rooftop size, and other factors. When considering solar panels, it is important to evaluate your energy requirements, roof space, and budget. The price of solar panels varies depending on home size and energy usage, and there are different payment options available. You can pay upfront for the largest lifetime savings, or opt for a monthly payment plan with zero or minimal upfront costs.
In Malaysia, the government is offering a RM4k SOLARIS subsidy to encourage the adoption of solar energy. This, coupled with the decreasing cost of solar, makes it a financially attractive option. Additionally, with the Net Energy Metering (NEM) Rakyat Program, any excess energy generated will be exported to the grid and you will receive credits to offset your electricity bill.
Solar panel installation companies in Malaysia, such as Solarvest, offer tailored solutions and professional installation services. They can guide you through the process, ensuring your system is efficient, reliable, and compliant with Malaysian energy regulations.
Solar panels can be a smart investment for your home, helping you save on electricity costs, increase your property value, and reduce your carbon footprint.

Unplug unused electronics
Unplugging unused electronics is a simple yet effective way to reduce electricity consumption and save on energy bills. Standby power can account for a significant portion of your electricity bill, so it's important to cut power to devices that are not in use.
This can be done by plugging your electronics into power strips and switching them off at the power strip when they are not in use. This applies to a range of devices, from televisions and computer monitors to chargers for phones and other small electronics. By unplugging these devices, you can stop any standby electricity consumption and amplify your savings.
It is also important to ensure that cords and cables don't sag over time, as they may pull out of their sockets and continue to draw energy. Investing in power strips can make this process easier, as you can switch off multiple devices at once, rather than having to unplug each device individually.
Remember, even when not in use, plugged-in devices can still consume electricity, so it is important to be mindful and proactive in unplugging them to save energy and reduce your environmental impact.
