Which of the following uses a nonrenewable energy source? A. Windmill B. Swimming pool C. Fruit Orchard D. Power Plant

I believe the answer is: power plant

An energy source is considered to be non-renewable if the reserve of the energy wouldn't be naturally replenished without any human intervention.

To create a power plant, we need to conduct a comprehensive chemical equation that wouldn't happen naturally.

Power plants would be best known for using a non-renewable resource, especially when these plants are operated through the use of fossil fuels and coal, rather than a clean source of energy. Any operations which does not use clean sources of energy would be using non-renewable sources.
