Despite Turning Off Inverter AC When Leaving Home, Electricity Bill Soars to 30,000 TWD! Taipower Exposes 6 Common Appliances That 'Burn Money' on Standby

During summer, many people turn on the air conditioning when they return home, making energy-saving tips a popular online topic. A netizen recently posted on Threads that despite turning off their inverter AC and lights when leaving home, and only using the dryer once a week (air-drying the rest), their electricity bill has skyrocketed to 30,000 TWD. The only appliances left running 24/7 are the dehumidifier and air purifier. Puzzled, they asked, 'What else can I possibly do to save electricity?'

After the post went viral, many users commented with suggestions: 'Possible electricity leaks include water pumps or booster pumps that never rest, broken insulation on split AC piping, electric water heaters running nonstop, or open windows and doors during cooling/dehumidifying causing air leaks—there might be other issues too.' Another user said, 'My entire two-story house uses less than 2,000 TWD every two months. Your two-month bill could cover my entire year! I replaced all five AC units with top-tier inverter models, and it’s super energy-efficient.' Others noted, 'Turning the AC on and off frequently actually consumes more power,' 'When I rented, I unplugged everything except the fridge before leaving,' and 'If your house is over 200 ping, it might be normal. Otherwise, something’s off.'

Many users specifically pointed out that 'Running a dehumidifier 24/7 is extremely power-hungry,' 'Dehumidifiers can consume even more power than AC units,' 'Only inverter-type dehumidifiers save energy—yes, they cost over 14,000 TWD, but they’re cheaper in the long run than a few-thousand-dollar power-guzzler. Also, consider whether you live in an apartment or high-rise—old wiring can waste electricity, and dryers are also big consumers.' One user suggested, 'Dehumidifiers use a lot of power. Check the wattage labeled on high-consumption appliances and ask an AI to calculate the hourly cost—that’ll reveal your electricity monsters.' Others added, 'Dehumidifiers are scarier than ACs—just run strong dehumidify mode for one hour a day,' and 'Inverter ACs are very efficient—probably the dehumidifier is the culprit.'

In fact, Taipower previously posted on its Facebook page about six common 'hidden electricity vampires' lurking in daily life. These appliances may seem harmless, but they silently drain your electricity bill.

1. Steady Offenders: Electric rice cookers, electric kettles, storage-type electric water heaters These appliances share the trait of 'requiring long-term temperature maintenance.' While their initial heating power is high, the real danger lies in the continuous 24/7 temperature maintenance, which steadily consumes massive amounts of electricity.

Taipower’s Recommended Countermeasures: - Use timer plugs: Install timer sockets for appliances that don’t need 24/7 warming. Set them to activate only during peak usage times to avoid wasteful all-day power draw. - Choose high-efficiency models: When purchasing or replacing, prioritize 'Energy Efficiency Level 1' energy-saving products.

2. Stealthy Hidden Types: TV set-top boxes, audio systems, inkjet printers Most people don’t fully power off these devices after use, leaving them in 'standby mode' for long periods. However, the tiny power draw in standby mode accumulates over time, making them 'quietly eat three bowls' electricity monsters that are often overlooked.

Taipower’s Recommended Countermeasures: - Use power strips with individual switches: Plug these devices into a power strip with independent switches. Simply flip the switch off when not in use to cut power completely. - Ultimate energy-saving tip: For long periods of non-use, 'turn off the main power and unplug the device.'

Taipower emphasizes that while different electricity vampires require different strategies, the most fundamental and effective 'ultimate energy-saving technique' is to consistently turn off the appliance’s main power and unplug it when not in use for extended periods. Adopting this simple daily habit not only reduces standby power consumption and saves unnecessary electricity costs but also significantly improves home electrical safety.
