What do you know about coal and its uses as a fossil fuel, and what type of impact it has on our environment? You may know that we use coal for a variety of different purposes, including the creation of electricity, but at what cost to our planet?

Coal is derived from plants that lived and died millions of years ago. It is the largest contributor to the increasing carbon dioxide percentage in the area. There are a number of toxic by-products involved in the coal refining and combustion process, including uranium, mercury, thorium and arsenic along with other types of heavy metal. Between seven and 30 percent of all coal contains non-combustible materials that must eventually be disposed of.

Lower-emissions coal is something that can be created, but it takes as much as 20 percent additional coal in order to create this cleaner-burning coal. This coal is not simply going to appear, but rather will have to be mined and this is a destructive process from an environmental standpoint. Additionally, the practice of mining coal itself is intensive in terms of carbon emissions, meaning that creating cleaner-burning coal actually contributes to more carbon emissions and environmental destruction rather than less.

Every person living in the United States uses approximately 3.8 tons worth of coal every year. Coal is responsible for providing approximately 23 percent of our global energy needs, and is responsible for generating approximately 39 percent of the electricity used around the globe. Coal is also necessary for global steel production, and approximately 70 percent of steel production depends on the use of coal.

The carbon dioxide emissions that come from the generation of coal-fired electricity in the United States are much greater than all of the emissions from America’s cars and trucks. Most average coal plants require the use of 14,600 railroad cars in order to provide 1.4 million tons worth of coal in a single year. A typical coal-fired, 500-megawatt power plant will draw in approximately 2.2 billion gallons worth of water every year, taking it from rivers, lakes, oceans and other nearby bodies of water.

Coal is regarded as an abundant type of fossil fuel resource and it consists primarily of carbon. The energy content of coal, in terms of Btu per pound can range between 5000 and 15000 depending on what type of coal you are relying on. There are coal reserves located all throughout the globe. Approximately 87 percent of all produced coal is consumed by our electric utilities. In the United States alone, half of all of the energy that is produced is done so with the help of coal.

Coal also happens to be used as a very basic energy source for a variety of different industries, and is also used as a fuel for heating. The United States is one of the biggest coal exporters in the entire world. Most of the coal exported away from the United States is transferred into Canada, Japan and Western Europe.

Coal is removed from the earth by way of deep mining or surface mining. Surface mining is also known as strip mining, and it is a less expensive form of mining that typically occurs above ground on flat land. On the other hand, deep mining requires the creation of deep tunnels and shafts to gain access to the coal. There has been some automation when it comes to deep mining, and this has helped in countering some of the health hazards and safety hazards that are inherent with this type of coal mining.

Coal is capable of being gasified in order to form a type of synthetic fuel that is similar to natural gas fuels. It is also capable of being made into a liquid for the creation of a synthetic crude oil. So far it has not been an economical proposition to create synthetic fuels out of coal, at least not on a large scale. However, as people continue to work on making these processes more efficient in general, it may become a more economical proposition to use synthetic fuels derived from coal in the future. This may also depend on how safe we can make mining for coal in the future.
