Which of the following is a source of nonrenewable energy?

Coal is identified as a source of nonrenewable energy because it is formed from the ancient remains of plant material that has been subjected to heat and pressure over millions of years. Once it is extracted and used for energy, it cannot be replaced on a human timescale. The amount of coal available is finite, leading to the classification of coal as a nonrenewable resource.

In contrast, wind and solar energy are renewable sources, as they harness natural processes that can be continuously replenished. Wind energy depends on atmospheric movements, while solar energy relies on sunlight, both of which are abundant and can be used indefinitely. Hydro energy obtains its power from water flow, typically through dams, and is also a renewable resource, relying on the water cycle. This cycle involves processes like precipitation and evaporation, ensuring a sustainable source of energy as long as weather patterns continue.
