2. Air conditioning energy saving tips

Air conditioning is the largest consumer of electricity in a household, and knowing how to use it correctly can significantly reduce your electricity bill.
  • Temperature set to comfortable range

    The recommended setting is 26-28°C in summer and 18-20°C in winter. For every 1°C increase/lower adjustment, approximately 6-10% of air conditioning electricity consumption can be saved.

  • Use with electric fan

    The power consumption of an electric fan is only 5% of that of an air conditioner. When used together, the air conditioner temperature can be increased by 2-3°C without affecting comfort.

  • Clean the filter regularly

    Clean the filter every two weeks, a dirty filter will reduce operating efficiency by 15-20%

  • Make good use of the timing function

    Set a timer to shut down before going to bed, or use sleep mode to automatically adjust the temperature

  • Reduce indoor heat sources

    Close blackout curtains during the day to reduce heat from direct sunlight and reduce the burden on air conditioning

  • Keep doors and windows closed

    Make sure the doors and windows are closed tightly when turning on the air conditioner to avoid wasting air-conditioning due to leakage

Tip

  • Turn off the air conditioner 15-30 minutes before going out and use the remaining indoor temperature
  • Long-term operation of inverter air conditioners saves more energy than frequent switching

3. Lighting energy saving solution

Lighting accounts for about 10-15% of household electricity consumption, and replacing energy-saving lamps and developing good habits are the easiest ways to save energy.
  • Replace LED bulb

    LED bulbs use approximately 80% less electricity than traditional incandescent bulbs and last up to 15,000-50,000 hours

  • Make good use of natural light

    Make full use of natural light during the day and choose light-colored curtains to increase indoor lighting.

  • Zone lighting

    When lighting the entire room is not needed, turn on only the required area lights and use table lamps instead of ceiling lamps.

  • Install sensor switch

    Install human body sensor switches in short-term use areas such as corridors, stairs, and bathrooms to automatically turn on and off lights.

  • Choose appropriate brightness

    Brighter is not always better, just use low brightness lamps in bedrooms and corridors

Light fixture type Power (equivalent brightness) life Annual electricity cost
incandescent light bulb 60W Approximately 1,000 hours high
Energy saving light bulb (CFL) 13W Approximately 8,000 hours middle
LED light bulb 10W Approximately 25,000 hours Low
Smart LED light bulb 10W (dimmable) Approximately 25,000 hours lowest

Tip

  • When buying light bulbs, pay attention to lumens (brightness) rather than wattage. For the same brightness, choose the lowest wattage.
  • Light-colored walls and ceilings reflect more light and reduce lighting requirements

4. Energy-saving habits when using home appliances

Changing some daily usage habits can effectively reduce your electricity bill at no extra cost.
  • Refrigerator usage tips

    Keep 70% full for the best efficiency, avoid opening and closing the door frequently, allow hot food to cool before putting it in, and leave space for heat dissipation on the back of the refrigerator.

  • Washing machine running at full load

    Wait until the appropriate amount of laundry has accumulated before washing. Washing in cold water can save heating energy and make good use of the quick wash mode.

  • Avoid overuse of dryer

    Dry the clothes naturally when the weather permits. If you need to dry the clothes, dehydrate them thoroughly before drying them, which can save 30% of drying time.

  • Computer and screen management

    Set the automatic sleep time, shut down instead of standby when not in use, and lower the screen brightness to save power.

  • Eliminate standby power consumption

    Use an extension cord with a switch to cut off the power of standby appliances with one click when leaving home

  • Electric water heater management

    Set the timer switch to only heat when needed, and install heat insulation sleeves on the pipelines to reduce heat loss.

Tip

  • Smart sockets can set a time to automatically cut off power, making it easy to manage multiple electrical appliances.
  • View your electricity bill to understand usage trends and find out the months and reasons for unusual usage

5. Home insulation and ventilation

Good insulation and ventilation design can reduce reliance on air conditioning and fundamentally reduce energy consumption.
  • window insulation

    Install double-glazed windows or thermal insulation films to reduce heat transfer by 30-50%

  • Shade equipment

    Install exterior sunshades, shades or plant vines to block direct sunlight

  • roof insulation

    Residents on the top floor can lay insulation materials or reflective paint to reduce indoor temperatures.

  • Air tightness of doors and windows

    Check whether doors and windows are tight and use sealing strips to fill gaps to prevent heating and cooling air from leaking out.

  • Natural ventilation design

    Make good use of the principle of convection and open diagonal windows to allow natural air circulation to cool down.

Tip

  • Light-colored exterior walls and roofs reflect more sunlight and reduce heat gain
  • Placing plants by the window can increase the shading effect and beautify the environment.

6. Energy Saving Guide when Buying Home Appliances

When shopping for new appliances, pay attention to energy efficiency labels. Although high-efficiency appliances may be more expensive, they can save you considerable money on electricity bills over time.
  • Understand energy efficiency labels

    Pay attention to the energy efficiency level when purchasing. The higher the level, the more electricity you save. The first level saves about 40-60% electricity than the fifth level

  • Select frequency converter model

    The compressors of inverter air conditioners and inverter refrigerators can adjust their operating speed according to needs, saving 20-40% of energy compared to fixed-frequency models.

  • appropriate size

    Choose a size that meets your actual needs. Oversized appliances not only waste electricity but also waste space.

  • Consider full life cycle costs

    Purchase price + electricity fee + maintenance fee = real cost. The initial investment of the energy-saving model is higher but it is more cost-effective in the long run.

  • Smart home appliances

    Smart home appliances with Wi-Fi function can remotely control and monitor power consumption to help optimize usage habits

Tip

  • Before purchasing, check the actual power consumption evaluation of the model online. Don’t just read the label.
  • If the efficiency of old appliances is too low, it will save money to replace them early.

Important Notes

When purchasing home appliances, please make sure the voltage matches the socket specifications. Voltage standards may differ in different regions.

7. 2026 Smart Home Integration: Socket + Monitoring App

In 2026, smart home appliances are no longer high-end toys. Affordable smart sockets can be found for 500 yuan. With a mobile app, the power consumption of each socket can be remotely monitored. It is a key tool for advanced power saving:
  • Smart socket application scenarios

    Electric water heater: Set to heat 1 hour before use, air conditioning: automatically turn on at 6 pm, standby electrical appliances (TV/AV): automatically cut off power when leaving home

  • Recommended power monitoring app

    TP-Link Kasa (intuitive), Home Assistant (extreme flexibility, requires Raspberry Pi), Apple Home (Apple ecological integration)

  • The Rise of Matter Agreement

    In 2026, Matter 1.4 will be universal and interoperable across brands. When buying new appliances, give priority to those with the Matter label to avoid being tied to a single ecosystem.

  • Investment ROI calculation

    Assume that a set of 4 smart sockets costs NT$2,000, saving NT$200 on monthly electricity bills, and the cost can be paid back in 10 months. Pure savings in the follow-up

Brand model price Support platform Power consumption monitoring Remark
