Coal Essentials
Coal

One of our most prolific non–renewable energy sources, coal is the most plentiful fossil fuel produced in the United States. Coal has the distinction as a non-renewable energy source for the reason that it takes millions of years to create, regrettably while being classified as the most abundant sources for energy.

Our three traditional non–renewable energy sources; Oil, Natural Gas and Coal as we have discussed, are currently an abundant source of energy for the US. The creation of these sources although continues to take millions of years of decaying remains to build up into thick layers of organic materials. And through the heat and pressure process, and time, the top layers of this organic material are once again transformed into a non–renewable energy source we continue to make use of.

How is coal sourced?

Coals energy was created by the stored energy from various plants and animals that lived on earth hundreds and millions of years ago. The black or brownish–black sedimentary rock consisting of carbon and hydrocarbons is a highly combustible material. Its combustion quality is what makes coal so favorable.

Coal has made a great impact on American society and economy. Coal mining has shaped the economy in many regions and states, as it continue to do so today. When compared to other conventional fuels, coal is by far the cheapest and most abundant. However, it does have various negatives, such as pollution and its non-renewable quality.

Types

Based on timing and pressure, different types of coal can be formed:
