To what extent does Methane effect climate change and what are the uses and limitations of science in addressing this issue? Methane is influenced by various natural and anthropogenic factors such as landfills‚ farms‚ drilling for natural gas‚ and coal mining. All of these factors that generate Methane emissions create ground level o-zone which is not only hazardous for our health‚ but it is a great concern for our climate. EPA is one of several organizations that plays a significant role in encouraging

Introductory overviewAlmost all coal‚ nuclear‚ geothermal‚ solar thermal electric‚ and waste incineration plants‚ as well as many natural gas power plants are thermal. Natural gas is frequently combusted in gas turbines as well as boilers. The waste heat from a gas turbine can be used to raise steam‚ in a combined cycle plant that improves overall efficiency. Power plants burning coal‚ oil‚ or natural gas are often referred to collectively as fossil-fuel power plants. Some biomass-fueled thermal

and the invention of the airplane reduces the time of traveling from one side of the world to another one. Reviewing the use of fossil fuel in history‚ people used to use coal as a main source energy. After the second half of the industrial revolution‚ people switched from coal to oil‚ and then natural gas. Nowadays‚ coal‚ oil‚ and natural gas are the three main energy resources. The exploitation rate never catches up to the consumer rate. There are three main reasons. First of all‚ as the population

But unfortunately‚ we have failed to build dams‚ which are the main source of storing water and generating electricity. Electricity generated by oil‚ gas and coal is very costly. There are the several options for generating electricity: 1. Construction of Hydro- dams: Construction of hydro dams are necessary are necessary. We have failed to build dams since 1975‚ which is considered as the best source

(“U.S. EIA International Energy Statistics") Fossil fuels are of great importance because they can be burned (oxidized to carbon dioxide and water)‚ producing significant amounts of energy per unit weight. The use of coal as a fuel predates recorded history. Coal was used to run furnaces for the melting of metal ore
