Match each term to its definition
Draw a line connecting each term on the left to its correct definition on the right. Or write the matching letter next to each term.
| Term | Your answer | Definition |
|---|---|---|
| Renewable | A. The market operator that manages electricity supply across south-eastern Australia | |
| Non-renewable | B. The splitting of water molecules using electricity to produce hydrogen gas | |
| NEM | C. An energy source that is replenished naturally and will not run out on human timescales | |
| AEMO | D. Storage that uses gravitational potential energy by pumping water uphill | |
| Pumped hydro | E. A cell that converts sunlight directly into electrical energy using the photovoltaic effect | |
| Photovoltaic | F. An energy source that exists in finite quantities and cannot be replenished on human timescales | |
| Electrolysis | G. The National Electricity Market, the interconnected grid linking QLD, NSW, VIC, SA and TAS | |
| Baseload | H. The minimum level of electricity demand that must be met continuously, 24 hours a day |
1. Give ONE example of a renewable energy source and ONE example of a non-renewable energy source used in Australia. For each, state the primary fuel or resource used.
2. Why does a 100% renewable electricity grid still need large-scale energy storage? Use the terms "intermittent" and "baseload" in your answer.
