Coal can be used as an energy source and to make chemicals used in household material manufacturing. Peat can also be integrated into soil to help it retain and slowly release water and nutrients. Coal is an industry that is critical to countries in both the developed and developing world.DisadvantagesCoal is a nonrenewable source of energy. Obviously, reducing our dependence on coal needs to be led by governments and large corporations. In 2009, about 10% of the U.S. methane emissions came from ventilating underground mines; 2% resulted from surface mining.There are three major types of underground coal mining: longwall mining, room-and-pillar mining, and retreat mining.Underground Mining: Longwall MiningDuring longwall mining, miners slice off enormous panels of coal that are about 1 meter (3 feet) thick, 3-4 kilometers (2-2.5 miles) long, and 250-400 meters (800-1,300 feet) wide.

The CO2 emitted from brning coal is a major contributor to climate change: 46% of all carbon dioxide emissions are caused by burning coal, and coal accounts for 72% of the greenhouse gases emitted through electricity generation. Safe capture and storage of carbon dioxide, referred to as CCS, is a technology that would capture and store the carbon dioxide that is produced by combusting this fossil fuel. If the Coal is fully exhausted, it takes millions of years to reproduce. European Union (leading producer: Germany)5. Dump trucks used at strip mines often weigh more than 300 tons and have more than 3,000 horsepower.Strip mining can be used in both flat and hilly landscapes. The conversion to a liquid or a gas creates a fuel that burns cleaner as well, which limits the production of ash and other byproducts that are created by the combustion process.

Fly ash is produced by coal-based power plants and carries 100 times more radiation into the surrounding environment than a nuclear power plant that produces an equivalent amount of energy. Think of all the other countries that produce coal; they may have even higher waste production numbers and lower recycling statistics. Opencast coal mines mean miners rarely have to go too far underground; machinery does the majority of the hard work; extraction is relatively easy. Depending on the composition of the coal, these particulates can contain toxic elements and irritants such as cadmium, silicon dioxide, arsenic, and calcium oxide.In the U.S., fly ash must be captured with industrial scrubbers to prevent it from polluting the atmosphere. Outside the U.S., that number is even higher. The only thing that Coal makes is smoke, and there are very few other wastes. This means we have another 200 years of coal usage at current consumption levels above and beyond what our current stockpiles can currently provide. Energy is the ability to do work. Besides releasing many harmful gases, coal mining can also produce radioactively active chemicals. A rough comparison is that a ton of coal equals 100 gallons of fuel oil.
