Research Paper On Coal Energy

Coal Energy There are many different types of energy sources that are used in different countries across the world. One of these energy sources is coal. Coal provides as much a ⅓ of the entire world's energy. Coal also produces 30% of US energy. Coal is not, however, used in Idaho. Idaho does generate coal electricity but this energy is sold to neighboring states like Utah and California. There are many things about coal worth knowing especially if you plan to build a large power plant and are trying to decide what energy to use. Coal forms over millions of years making it a fossil fuel. This chemical substance is then mined and burned to produces thermal energy. In things like steam engines, this coal is used to heat the water in a tank. The pressure from the steam makes the pistons the wheels turn which is mechanical energy, and this motion moves the entire train. In other cases, the same process is repeated but instead of turning pistons, the steam turns turbines to produce electrical energy. Coal can also be used to make coal coke or just ‘coke’. This coke is used in the smelting of iron and steel ore and also produces less pollutants than regular coal …show more content…
Coal releases 42% of the worlds mercury pollutants. This can harm the human body by damaging the digestive tract and the immune system. Should this pollutant enter the body of an animal, it makes this animal unsafe to eat for both humans and other animals. Sulfur that is released reacts with oxygen in the air to form sulfur oxide. Sulfur oxide has been linked with things like causing asthma, bronchitis, and acid rain. Nitrogen produces fuses with oxygen in the air to form nitrous oxide has similar effects to sulfur oxide. Nitrous oxide can irritate asthma or considerably worsen it. It can even cause influenza or pneumonia. Other pollutants released by burning coal are arsenic, cadmium, selenium, Carbon Monoxide and other toxic heavy
