Energy Storage & Batteries
📋 What it is
Storage (batteries, pumped water) saves energy for later — the key to making solar and wind reliable.
🗣️ Coach says
Storage lets us save energy for when it’s needed. Batteries store electricity chemically; pumped-hydro pushes water uphill to release later. Storage is the missing piece for renewables — it banks solar power for night and wind power for calm days, turning "sometimes" sources into round-the-clock supply.
🧠 Memory hook
Storage (batteries, pumped-hydro) banks energy for later → makes solar/wind reliable 24/7.
😂 Giggle
Why was the geothermal plant so calm?
It had a lot of inner warmth!
😲 Whoa!
One clever storage method pumps water uphill when power is cheap and lets it flow back down through turbines when needed — a giant "water battery" you can see from space.
✅ Quick check: Why is energy storage so important for solar and wind power?
Say your answer out loud first — then reveal.
It banks the energy for when the sun isn’t shining or wind isn’t blowing, making these sources reliable.
Storage smooths intermittent renewable supply.

Think of a power bank charging your phone later — storage on a small scale, same idea as the grid’s.
