Explain why renewable energy sources like solar, wind, and geothermal power have more limitations to their use than the burning of fossil fuels.

Answer:

Fossil fuels can be burned anywhere, at any time day or night, meaning there really are no restrictions to their use. Alternative, renewable, energy sources are generally restricted in their use, either geographically or based on weather or time of day. Solar power is only available when the sun is shining, which is only about half the time. Wind power, meanwhile, is dependent upon wind blowing and geothermal power is restricted to volcanically active areas.
