🧠 Memory Aids
FINITE = Runs out like a FINITE number: When you reach the end of a finite number sequence, there is nothing left. Coal, oil, and gas are the same — once they are gone, they are gone.
RENEWABLE = RE-NEW (grows BACK): The prefix "re-" means again. Solar energy, wind, and biomass all come back again naturally. Think "RE-place, RE-new, RE-fill."
The 4 Rs of sustainability — RRRR:
- Reduce — use less
- Reuse — use again without reprocessing
- Recycle — reprocess into new material
- Replace — switch to a renewable alternative
Mnemonic for examples: "COFFINS are Finite" — Coal, Oil, Fossil fuels, Ferritic metals (iron), Iron ore, Nuclear fuel, Sand/gravel.
