Efficiency & Conservation
📋 What it is
Using less energy for the same result (efficiency) and using less overall (conservation) both save power.
🗣️ Coach says
Two ways to cut energy use: EFFICIENCY (get the same result with less — an LED for the same light as an old bulb) and CONSERVATION (simply using less — turning things off). Both save money and reduce pollution. The cheapest, cleanest energy is the energy you never have to make.
🧠 Memory hook
Efficiency = same result, less energy. Conservation = use less overall. Cheapest energy = the unused kind.
😂 Giggle
What did the power grid say during peak demand?
"I'm feeling a little overloaded right now!"
😲 Whoa!
Swapping one old bulb for an LED saves so much power that if everyone did it, the world could switch off hundreds of power plants.
✅ Quick check: What’s the difference between energy efficiency and conservation?
Say your answer out loud first — then reveal.
Efficiency = same result using less energy (an LED); conservation = using less overall (switching off).
Efficiency improves the ratio; conservation reduces the amount.
