Air Pollution. The process of burning coal for energy produces greenhouse gases and other harmful pollutants, including carbon dioxide, mercury compounds, sulfur dioxide and nitrogen oxides. Per unit of electricity, coal produces more pollution than any other fuel source, according to the Environmental Protection Agency.
Coal seams are removed with excess soil and rock placed in an adjacent valley. Large scale earth moving equipment is used to excavate and remove coal from lower layers. The equipment used depends on the method and scale of the surface mining method being employed. Regrading begins as coal excavation continues.
Mar 21, 2008· Coal is mainly used for generating electricity (more than 90 % of US coal). Coal usually has a negative impact on environment, mining can damage ground and surface waters and when coal burns as the fuel it releases CO2 which is the main greenhouse gas that causes global warming.
Advantages and Disadvantages. Geothermal fields produce only about onesixth of the carbon dioxide that a relatively clean naturalgasfueled power plant produces. Binary plants release essentially no emissions. Unlike solar and wind energy, geothermal energy is always available, 365 days a year.
Coal is another fossil fuel used to generate electricity and is found closer to the Earth's surface. Although fossil fuels are mainly used to make electricity, they are also used to power machines such as cars and planes. Fossil fuels are nonrenewable which means they cannot be made by humans.
Below are 25 Interesting Facts About Fossil Fuels. Fact 5: Coal is a combustible rock that is black in color. It runs in veins through the rock beneath the surface of the Earth. Coal mines allow miners to go underground to remove the veins from the rock itself. Fact 6: Natural gas is a form of methane.
No source of energy can boast of only having advantages, and no disadvantages; coal is no exception. Though it has several disadvantages, some of which are quite prominent, it also has some advantages.
