Name a renewable energy source — Best Krillion Answers
Facing “Name a renewable energy source” in a dive? Here is how to think rare: the best picks, the safe backups, and the crowd defaults to avoid. Every answer below is real and valid — rarity decides the tier.
Best rare pick: Tidal energy — specific, valid, and uncommon enough for Deep Cut or better.
Avoid (Plankton): Sunlight, Wind — correct, but the crowd's first thought.
One in a Krillion — 100 pts
The rarest valid answers — maximum depth.
Tidal energy · Salinity gradient power
Deep Cut — 85 pts
Extremely rare picks most players miss.
Wave energy · Algae biofuel
Rare — 60 pts
Genuinely uncommon — strong scoring.
Geothermal energy · Biomass
Schooler — 30 pts
Known but not top-of-mind.
Hydropower · Biofuel
Too Clever — 15 pts
A bit too obvious.
Wind energy · Solar energy
Plankton — 10 pts
The crowd's default — avoid these.
Sunlight · Wind
How to play this prompt
Strategy notes specific to “Name a renewable energy source” — not generic advice.
Science prompts punish approximations. Name it exactly and you dive deeper.
Lead with Tidal energy. It's the kind of answer that makes other players say 'I knew that!' after the reveal — which is exactly why they didn't type it. Wave energy works the same way if you want a second bullet in the chamber.
Watch out for Sunlight. It's valid, but validity isn't the game — rarity is. Wind has the same problem: everyone knows it, so everyone types it, so it scores like everyone.
Notice how Geothermal energy (Rare) outscores Sunlight (Plankton) without being obscure at all. Rarity isn't about difficulty — it's about what the crowd overlooks.
Rare answers travel in packs: if Algae biofuel comes to mind, Biomass and Wave energy are usually one thought away. Train yourself to pull the whole cluster, not just the first name that surfaces.
Rated 4/5 difficulty — only 12 banked answers, so matching the bank is genuinely hard. Precision matters more than speed here.
