Everything about coal

How it's formed

For millions of years,a layer of dead plants at the bottom of the swamps was covered by layers of water and dirt,trapping the energy of the dead plants.The heat and pressure from the top layers helped the plant remains developed into what we now call coal.


Advantages,coal is a fossil fuel used to produce around 40 percent of the worlds electricity.Coal is also one of the most abundant sources of energy,more so than oil and natural gas.Coal is inexpensive when compared to other fossil fuel (or alternative energy sources.)

Disadvantages,coal takes millions of years to form.Theres a 235-year supply at current rates of use.Coal is also a big factor in global warming.

Carbon dioxide burns off the coal which is bad for the environment.Now there's going to be a blanket like cover that goes over furnaces or power plants to let the oxygen go through and the carbon dioxide stays kept inside the plant.This will make it to where oxygen gets through and the carbon dioxide doesn't hurt the environment.
