Match each renewable source to its energy transformation
Draw a line connecting each energy source on the left to its correct primary energy transformation on the right. Or write the matching letter next to each source.
| Renewable Energy Source | Your answer | Primary Energy Transformation |
|---|---|---|
| Solar PV (photovoltaic) | A. Gravitational potential energy → kinetic energy → electrical energy | |
| Wind turbines | B. Chemical energy → thermal energy → electrical energy | |
| Hydroelectric | C. Light energy → electrical energy | |
| Solar thermal | D. Kinetic energy (of wind) → electrical energy | |
| Bioenergy | E. Light energy → heat energy → mechanical energy → electrical energy |
Fill the gap
Choose the correct word from the word bank to complete each sentence about Australia's transition to renewable energy.
Australia is rapidly expanding its energy sector. The country receives more radiation per square metre than almost any other nation, making cells, which convert light directly into electricity, an ideal choice for Australian homes and farms. Large farms across Victoria and South Australia harness the kinetic energy of moving air. One key challenge with solar and wind is that they are they don't always produce electricity when people need it most. The Snowy Mountains scheme provides reliable baseload power and is being expanded. A major advantage of all renewable sources is their very low carbon compared to burning fossil fuels.
1. Name TWO renewable energy sources used in Australia and give ONE advantage they share.
2. Explain ONE limitation of solar power as an energy source for Australian homes.
