Question
- A. They are classed as renewable because their energy source is naturally replenished.
- B. They are renewable because they never affect habitats or landscapes.
- C. They are renewable because they always produce electricity at a constant rate.
- D. They are renewable because they are all stored underground as fuels.
Answer
They are classed as renewable because their energy source is naturally replenished.
Explanation
Natural replenishment is the defining idea. Wind, sunlight, tides, waves, water flow, geothermal energy and regrown bio-fuels can be replaced by ongoing natural processes. That does not mean they have no environmental impact or perfectly constant output.
Common mistake
Confusing Bio-fuels with Fossil Fuels
Students often confuse bio-fuels with fossil fuels, thinking they are the same type of energy resource.
Remember that bio-fuels are derived from biological materials and are renewable, while fossil fuels are non-renewable resources formed from ancient organic matter.
