Correct it:
Renewable energy sources produce absolutely no greenhouse gas emissions, ever — even during manufacturing.
Correct it:
Coal, oil and natural gas are all classified as fossil fuels because they formed from the remains of ancient living organisms.

Odd one out
Circle the item that does not belong in each group. Then explain why it doesn't fit in the answer column.
| # | Group | Your answer (odd one out + reason) |
|---|---|---|
| 1 | Solar Wind Hydro Coal | |
| 2 | Coal Oil Natural gas Geothermal | |
| 3 | Biomass Tidal Geothermal Nuclear | |
| 4 | CO₂ Methane Uranium Greenhouse gas |
1. Explain why nuclear power is classified as non-renewable even though it does not release CO₂ during operation.
2. Name two challenges that make it difficult to rely solely on solar and wind power for Australia's electricity supply.
