2. Fossil Fuels: Pollution whether it is vehicular, electrical or industrial is the main contributor to the global warming. Everyday billions of vehicles release various gases into the atmosphere. This causes earth to warm up and increase its average temperature. Electricity causes pollution in many ways. Over 75% of the electricity worldwide is produced by burning of fossil fuels. Many gases are sent into the air when fossil fuels are burnt of which main is the carbon dioxide gas.
Fossil fuel like coal is burnt to produce electricity. Coal is the major fuel that is burnt to produce power. Coal produces around 1.7 times as much carbon dioxide per unit of energy when flamed as does natural gas and 1.25 times as much as oil.
We’re all well aware of the vast amounts of energy consumed everyday by humans everywhere since our first memories. Nearly 40% of the U.S. release of carbon dioxide is due to the burning of fossil fuels-gasoline and electricity in our homes. Finding sources for renewable energy, clean burning fuel options, and methods to cut back the amount of energy exhausted, could cut that 40% significantly.
Industries on the other hand release various gases into the water and air. Carbon dioxide, methane and nitrous oxide are the major greenhouse gases. Different gases have different heat trapping capabilities. Some of them trap more heat than carbon dioxide. Methane is much more effective then carbon dioxide in entrapping heat in the atmosphere. By driving cars, using electricity from coal fired plants and heating up our homes from natural gases, we release carbon dioxide and other heat trapping gases in the atmosphere.
