Detailed explanation-1: -Nonrenewable energy resources include coal, natural gas, oil, and nuclear energy. Once these resources are used up, they cannot be replaced, which is a major problem for humanity as we are currently dependent on them to supply most of our energy needs.

Detailed explanation-2: -Coal is classified as a nonrenewable energy source because it takes millions of years to form. Coal contains the energy stored by plants that lived hundreds of millions of years ago in swampy forests. Layers of dirt and rock covered the plants over millions of years.

Detailed explanation-3: -Coal is a non-renewable energy source because it takes millions of years to form.

Detailed explanation-4: -Hydrocarbon fuels include coal, fossil fuels, crude oil, natural gas, and others. These are non-renewable energy sources.

Detailed explanation-5: -Wind and sunlight are renewable resources that can be replenished as we use them, unlike natural gas and petroleum, which will deplete with extraction and, hence, cannot be renewed. Therefore, natural gas and petroleum are identified as non-renewable resources.
