Misconceptions & Reasoning
📋 What it is
Test "obvious" energy ideas against evidence — many beliefs about power and saving energy are wrong.
🗣️ Coach says
Energy has feels-right-but-wrong ideas: energy isn’t "used up" and gone (it converts, often to waste heat), "renewable" doesn’t mean unlimited-anytime (the sun sets, wind stops), and leaving a device on standby still draws power. Reason from how energy actually flows, not from slogans.
🧠 Memory hook
Feels-true ≠ is-true. Energy converts (to waste heat), it isn’t destroyed; standby still uses power.
😂 Giggle
Why was the electricity bill so shocked?
It couldn't believe the current charges!
😲 Whoa!
Devices left on "standby" — TVs, chargers, consoles — quietly draw power all day; these "energy vampires" can add up to about 10% of a home’s electricity.
✅ Quick check: Does a phone charger left plugged in (with no phone) use any energy?
Say your answer out loud first — then reveal.
Yes — it draws a small "standby" amount continuously; these vampire loads add up.
Standby devices consume power even when idle.
🧪 Try it! (2 minutes)
Feel a charger plugged in with nothing attached — slight warmth means it’s still drawing power.
