// LESSON NOTES
"A TV on standby uses no power." Myth or fact? 📺🔴
❌ MYTH! That little red light means the TV is still on: a tiny power supply stays awake, listening for your remote.
⚡ A new TV uses about 0.5–1 W on standby — every hour, all year (24 h × 365 days = 8,760 hours).
📊 1 W × 8,760 h ≈ 9 kWh a year. Old set-top boxes can use 10 W or more on standby — about 10× as much (≈ 90 kWh a year).
✅ Tip: switch off at the wall (or use a power strip with a switch).
📌 Small, but never zero.
