Coal is one of the most important sources of energy that we have today. But even though it is common and can be found almost anywhere, only few people really know what it really is. For you to be able to fully appreciate the wonders that coal has done to improve people’s way of living around the world, then it is only important for us to know more about it. So here is everything that you need to know about coal.
What is coal?
Coal is basically a carbon rock that can be burned to be able to release energy. It is a fossil fuel from the remains of plants and animals. A coal is an organic material which contains hydrogen, oxygen as well as nitrogen.
How is coal formed?
Coals were formed during the time when large amounts of plant life and other organic matter died. They then drifted down to the bottom of the swamps and eventually decomposed and were buried deep in the ground. Over millions of years, these decomposed materials were subjected to a lot of heat and pressure and thus coals were formed.
Where is coal found?
Coal in the United States is more than 60 percent of the world’s total fuel reserves. The world has plenty of fuel supplies that they can use for about 250 more years. It is interesting to note that the world actually mines about 4 billion tons per year while the United States alone mines over a billion tons annually.
How is coal mined?
There are basically two ways in which coals are mined. Others use surface mining, a process wherein the topsoil and subsoil is removed through the use of large machineries to be able to uncover the coals. After the coal is removed, the soil is refilled and reseeded. On the other hand, underground mining is the conventional way of getting coal by extracting it deep beneath the surface. Shafts or openings are usually created and explosives are often employed to get the very much needed coal.
What is coal used for?
Coal is important because it is particularly used to generate electricity. Most countries in the world actually use coal because it is proven to be a reliable and low cost energy source.
Coal really plays an important role in every country’s advancement and other energy needs. It is only important for us to know all the basic things that we need to know about coal especially how it is formed, where it is usually found and how it is mined. Knowing these things can help us realize the importance of this seemingly little and commonplace material which is actually one of the most important mineral in the world today.
