Final answer:

Coal formation, usage as a non-renewable resource, and environmental impacts


Explanation:

Coal is a fossil fuel formed from prehistoric vegetation in layers of sediment over millions of years. When burned with oxygen, coal produces carbon dioxide, releasing heat energy.

Coal is a non-renewable energy source as its formation process is time-consuming and the current reserves are limited, leading to significant environmental impacts when burned.

Using coal to generate electricity accounts for over 50% of the US electricity production, despite the harmful emissions of sulfur dioxide, nitrogen oxides, heavy metals, and carbon dioxide released during combustion.
