Deck MO6842 — Renewable Energy holds 83 cards that follow one long encyclopedic article source by source: the big picture and grid problems (cards 1-16), solar (17-26), wind (27-28), hydro (29-36), bioenergy (37-50), geothermal (51-59), emerging technologies (60-68), then a glossary tail (69-83). Knowing that structure is the key to studying it well.

Sample cards
| Front | Back |
|---|---|
| Capacity factor | Ratio of actual energy production to the maximum possible production |
| What accounts for 85% of grid power storage? | Pumped-storage hydroelectricity |
| Swanson's law | Solar module prices drop about 20% for each doubling of installed capacity |
| Conversion efficiency of hydroelectric power | About 90%, the highest rate in renewable energy |
| Why is water effective for energy generation? | About 800 times denser than air |
| CO₂ from burning biomass vs fossil fuels | 39 g/MJ vs 75 g/MJ |
| Share of Kenya's electricity from geothermal | 43% |
| Largest tidal power station | Sihwa Lake, South Korea, ~550 GWh/year |

Tip 1: suspend the glossary tail's repeats
Cards 69-83 re-teach earlier material: energy storage (79) repeats card 11, learning curve (83) is Swanson's law from card 23, and pumped storage appears at both 12 and 36. Keep the earlier, number-rich versions and suspend the rest. Rewrite card 78 while you are there: it says a solar thermal collector concentrates sunlight with mirrors or lenses, but that describes CSP (card 24). Most rooftop collectors, flat-plate and evacuated-tube, concentrate nothing.
Tip 2: patch the wind gap and date your numbers
Wind, one of the "big three" sources in card 2, gets just two cards. Add four yourself: how a turbine converts wind to electricity, the Betz limit (59.3%), typical onshore vs offshore capacity factors, and the fact that power scales with the cube of wind speed. Then tag every dated figure: wood as top biomass source is "as of 2012", PV growth is 2021 data, and Golmud is no longer the record holder: China's Midong plant in Xinjiang (3.5 GW, 2024) now claims the title. A quick check of current rankings keeps your answers exam-safe.
