As winter approaches, many people might feel like the days are flying by quickly. But don’t worry—electricity bills don’t have to skyrocket. With a few simple tricks, you can save energy without compromising comfort. For instance, turning down the volume on your TV or using low-bubble detergents for laundry can make a noticeable difference. This week, we’ve gathered some practical tips to help you conserve energy around the house. Let’s dive into how you can save electricity on common appliances.
TVs Save Energy
Did you know that adjusting the brightness and volume of your TV can significantly impact its energy usage? A larger screen size might look impressive, but it also consumes more power. If your living space isn’t particularly large, there’s no need to splurge on an oversized TV. Reducing the brightness not only cuts electricity costs but also prolongs the lifespan of your device and protects your eyesight. Interestingly, a color TV can vary in power consumption by up to 60 watts depending on whether it’s set to maximum or minimum brightness. Additionally, keeping the volume moderate helps save energy since every extra watt of audio power increases overall consumption by about 3 to 4 watts. Always remember to unplug your TV when it’s not in use, as even in standby mode, it can drain significant amounts of electricity over time. Covering your TV with a dust cover can also help prevent dust accumulation, which could lead to electrical leakage and degrade performance.
Save Energy with Air Conditioning
Lowering the Temperature by 2 Degrees Saves 10%
Turning on the air conditioner during winter is a luxury many enjoy, but it can come at a cost. Setting the temperature too high can quickly hike up your energy bill. A smarter approach is to keep the indoor temperature slightly cooler than usual—just enough to feel comfortable without overheating. Ideally, aim for temperatures between 18 and 23 degrees Celsius in winter. Adjusting the thermostat down by just one or two degrees is unlikely to be noticeable, yet it can save you up to 10% on energy consumption. When first turning on the air conditioner, set it to high heat to reach the desired temperature quickly. Once the room feels comfortable, switch to medium or low fan settings to reduce energy use and noise levels. Be sure to avoid leaving the “ventilation†feature constantly on, as this will increase power consumption unnecessarily.
Minimizing drafts by closing windows and doors can help retain warmth indoors. Heavy curtains are another effective way to trap heat within the room. If you’re planning to install an air conditioner, try to keep the connecting pipes as short as possible and ensure proper insulation to minimize energy loss. Regularly cleaning the air filter is essential, as clogged filters hinder airflow and reduce efficiency.
Washing Machines Save Energy
Efficient Low-Bubble Detergents
Saving energy with a washing machine requires some strategic planning. The duration of each cycle depends on the load size and dirtiness level. For example, delicate fabrics like silk or wool require gentle washing cycles lasting around 2 to 4 minutes, whereas heavier items like cotton or linen might need 5 to 8 minutes. Extremely dirty garments may require up to 10 to 12 minutes. Rinsing typically takes about 3 to 4 minutes.
Using the right washing mode is crucial. Most machines offer strong, medium, and weak settings, each with varying power demands. Delicate materials like silk or wool should always be washed on the gentlest setting, while synthetic fibers and blended fabrics can handle medium settings. Only heavy-duty items, such as thick blankets or canvas upholstery, benefit from stronger cycles. After washing, squeezing out excess water manually can cut down on rinsing time and save energy. Separating light and dark clothing and choosing appropriate wash durations based on soil levels also contribute to energy savings. Opting for low-bubble, high-efficiency detergents further boosts efficiency, as these products boast superior cleaning power while using less detergent per load.
Refrigerators Save Energy
Avoid Repeated Freezing of Large Portions
Frequently opening the refrigerator door wastes energy, but so does repeatedly freezing large portions of food like meat. Instead, portion food according to household needs and only take out what you’ll eat at once. This prevents unnecessary energy loss and keeps food fresher longer. Thawing frozen food ahead of time is another energy-saving strategy. Moving items from the freezer to the fridge before leaving for work allows them to defrost naturally, utilizing the fridge’s cooling system efficiently. Avoid placing hot food directly into the refrigerator, as this raises internal temperatures and increases energy consumption. To ensure the door seals tightly, test it by inserting a piece of paper between the closed door and frame—if it slides out easily, adjust the door accordingly.
Tailoring the fridge’s temperature to suit stored items ensures optimal performance. Fresh meats and fish should be kept around -1°C, while eggs and milk thrive at approximately 3°C. Vegetables and fruits perform best around 5°C. Seasonal adjustments play a role too; during summer, set the temperature control knob to "4," while lowering it to "1" in winter. If your fridge sits in a well-lit area, consider removing the interior light bulbs to save further energy.
Rice Cookers Save Energy
Cleaning the Heating Plate Regularly
Many people overlook the fact that rice cookers can be energy-efficient tools. Two straightforward methods exist: investing in a higher-wattage model and regularly cleaning the heating plate. A 700-watt rice cooker, for instance, uses less electricity than a 500-watt version when cooking the same amount of rice. For example, cooking 1 kilogram of rice takes 30 minutes and consumes 0.25 kWh with a 500-watt cooker, compared to just 20 minutes and 0.23 kWh with a 700-watt one. Keeping the heating plate spotless prevents oil residues from carbonizing over time, ensuring better thermal conductivity and reducing power usage. When the rice cooker switches from red to yellow light, it indicates the meal is ready. At this point, turning off the power lets the residual heat finish cooking without additional electricity.
