plz explain to me as to why coal is not a renewable energy?

Answer 1

Coal is formed from the buried remains of ancient plants and animals that has been subjected to a lot of pressure. This has taken many millions of years to occur. Since the source material (plants and animals) is not unlimited, coal is not renewable. When you use it up, it is gone. When you burn coal, in addition to the heat that it gives off, it gives of carbon dioxide and water vapor. These byproducts are transferred to the atmospheric pool. Carbon dioxide is a greenhouse gas. Too much CO2 results in overheating in the atmosphere. Some of this CO2 is dissolved in the oceans where some ocean organisms can then use it to make their shells. When they die, these shells are returned to the sediments.

Green plants use some of the CO2 in the process of photosynthesis and produce glucose which is used by the plant and by all the animals that eat the plant for energy.

However, coal takes millions upon millions of years to form. Therefore, even though the carbon can be recycled, coal is considered to be a nonrenewable resource . . . especially in our life times.

Hope this helps.
