Many people focus on big travel hacks—packing tricks, discount flights, seat upgrades—but there's a lesser-known tip that not only helps during flying but also makes you more energy-efficient back at home. A post on Tạp Chí Đời Sống claims that by paying attention to a certain spot (or action) while on an airplane, you can derive a habit that saves “millions in electricity bills per year.” (Tap Chí Đời Sống) (source preview)

From social media previews, the post appears to share a “life hack” about cleaning or optimizing a particular location—perhaps in the aircraft or your home—that often gets overlooked, yet has outsized impact on power use or fuel consumption. (Facebook previews) (turn0search0)

Here’s an enriched breakdown of the likely tip, why it matters, how it might apply to electricity savings, and what experts say about analogous practices.

What the Tip Probably Is — Based on Inference

Though I don’t have the full article text, the title suggests something like:

“If you fly, you must know this spot — it could save you millions in electricity per year.”

Likely possibilities include:

• A trick to turn off overhead lights or cabin modules when unused on flights, which mimics habits at home to reduce unnecessary lighting/appliance use.

• A method to optimize seat lighting or power outlets in aircraft, thereby avoiding draw from auxiliary systems that waste energy.

• A related habit you carry from flying to home life, such as always turning off “phantom loads” (appliances in standby) or cleaning air vents to improve HVAC efficiency.

In short: the article probably encourages being mindful of small power draws or inefficient systems, both in travel and daily life.

Why Such Small Tips Matter — Energy & Efficiency Insights

• Standby power (“phantom load”): Many household devices (chargers, TVs, appliances) continue to draw electricity even when switched off but still plugged in. According to the U.S. Department of Energy, phantom loads can account for 5–10% of home energy use.

• Lighting efficiency: Old or unclean light fixtures reduce efficacy, meaning more power is needed to generate the same light. Keeping bulbs, covers, and vents clean helps maximize lumen output per watt.

• Ventilation and air flow: Dirty vents or filters make HVAC units work harder, consuming more electricity. Cleaning them regularly lowers energy consumption.

• Behavioral carryover: A habit formed in one context (e.g. turning off an aircraft reading light when not needed) often translates into better habits at home—turning off lights, unplugging devices, or optimizing settings.

Suggested Tip Inspired by the Headline

Combining the inferred tip with energy hygiene practices, here’s a possible takeaway:

Check and clean “low-visibility” spots — like overhead lamps, vent grills, socket covers, power strips, or control panels — on all equipment (aircraft, home appliances). Dust, grime, or misalignment can cause inefficiencies, extra power draw, or even heat loss.

For example:

1. On an airplane: before takeoff or when you’re not reading, turn off your personal reading light—it still draws from the aircraft’s lighting circuits.

2. At home: every few months, dust or wipe your overhead fixtures, power sockets, transformer bricks, router, and fridge coils to reduce drag and power leakage.

What Experts Recommend

• Energy efficiency studies consistently show that maintenance matters. A well-maintained HVAC, clean filters, and dust-free fixtures use significantly less energy than neglected systems.

• Many utility companies offer free energy audits emphasizing such small actions (cleaning, unplugging, sealing leaks) over expensive upgrades.

• Green building and sustainability sources stress that habitual behavior, not just efficient hardware, often provides the greatest incremental savings over time.
