- C. They all require radioactive fuel that must be stored after use.

Answer
Their energy sources come from cycles or stores that are naturally replenished.
Explanation
The evidence is the source of the energy: sunlight, moving air, moving water, tides, waves, Earth?s internal energy, or regrown biomass. These sources can be replenished naturally, unlike fossil fuels or uranium fuel.
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.
