[Home Tips] Energy-saving and electricity-saving methods: How to use electricity most economically?
🔍 Why should Hong Kong people pay special attention to electricity expenses?
Hong Kong's electricity costs aren't the lowest compared to other parts of Asia, especially with its hot summers and humid winters. High-energy appliances like air conditioners, dehumidifiers, and water heaters are in near-year-round use. Furthermore, the fact that most Hong Kong households live in high-rise buildings with limited ventilation and natural light further increases electricity demand.
Reasons for high electricity bills include:
- 🔥Using the air conditioner for a long time in summer
- 💧The dehumidifier is on all the time during the rainy season
- 🍳High -power cooking such as induction cookers, microwave ovens, and ovens
- 📺Long standby time for home appliances
- 💡The lighting system still uses high-energy-consuming bulbs
💡Editor ’s opinion : Energy saving does not mean enduring heat or darkness, but rather achieving the same level of comfort using more efficient methods.
📊 Hong Kong's major household appliances power consumption rankings (reference average values)
Ranking | electrical appliances | Power consumption characteristics | Annual electricity consumption (estimated) |
---|---|---|---|
1️⃣ | air conditioner | Long-term use in summer, high power | 800-1200 kWh |
2️⃣ | dehumidifier | Often open during the rainy season and winter | 500-900 kWh |
3️⃣ | water heater | High heating power consumption | 400-800 kWh |
4️⃣ | refrigerator | 24-hour operation | 300-600 kWh |
5️⃣ | Cooking appliances | Cooking time is the most energy-intensive | 200-500 kWh |
🛠️ Energy and electricity saving methods (Hong Kong version)
The following methods, based on our own real-world testing and data analysis, can help you save on electricity without compromising your quality of life💰:
1️⃣ Air Conditioner
- Set the temperature to 25-26°C → Every 1°C increase in temperature can save about 6% of electricity.
- Turn on "Dehumidification Mode" : It saves more energy than cooling mode in hot and humid weather.
- Clean the dust filter regularly : keep the airflow smooth and reduce the compressor running time.
- With fan-circulated air : you can use higher temperature settings and still feel cool.
2️⃣ Dehumidifier
- Choosing an inverter dehumidifier can reduce power consumption by about 30%.
- Use at the right time: Turn on the device only during the rainy season or when the indoor humidity is > 70%.
- Use the timing function to avoid running all night.
3️⃣ Water heater
- Adjust the water temperature to 40-45℃ to avoid overheating and wasting electricity.
- Keep bathing time within 5-10 minutes⏳.
- If there are few people at home, you can choose an instant water heater to avoid long-term heat preservation and electricity consumption.
4️⃣ Lighting
- Replace all light bulbs with LED bulbs (which use about 80% less energy than incandescent bulbs).
- Make good use of natural light and reduce the time you keep lights on during the day.
- For spaces that are used for short periods of time, such as kitchens and toilets, use sensor lights or timed lights .
5️⃣ Home Appliance Standby
- Televisions, game consoles, computers, etc. still consume power in standby mode after being turned off.
- Use the switch to cut off the power with one click.
- Unplug your phone or laptop charger once it is fully charged.
6️⃣ Refrigerator
- Set temperature: 3-5℃ for refrigerator, -18℃ for freezer.
- Do not overcrowd or keep the door open for too long to maintain air circulation.
- Defrost regularly to avoid increasing the burden on the compressor.
📉 Editor's test case
My home's monthly electricity bill was originally about $650 . After the following adjustments:
- Air conditioner set to 26℃ + fan circulation
- The dehumidifier only turns on when the humidity is above 70%.
- Replace the entire house with LED lights
- All electrical appliances are turned off with switch boards
💡 Result: Electricity bill dropped to $480/month , saving over $2,000 a year! 🎉
💡 Editor's Warm Suggestions
- First, find out the major electricity consumers in your home (use your electricity meter or analyze your power company bill).
- Improve gradually . There is no need to replace all appliances at once. Start by changing your habits.
- Investing in energy-efficient appliances (products with energy efficiency labels) may cost more to purchase but will save you money in the long run.
