Explanation:
Natural gas comprises about a quarter of the United States’ energy use. It is more environmentally friendly than oil and coal due to lower carbon dioxide (CO2) emissions per unit, less costly per unit of energy and more readily available domestically in abundant supply. However, due to a number of barriers in the political, infrastructural, pricing and other arenas, the use of natural gas as a significant energy source in the United States has been limited. In our paper, we highlight the favorable qualities of natural gas and its benefits for the consumer, producer, and environment, having compared the costs of the various components of the natural gas business such as drilling and transport to that of coal and oil. Moreover, we touch upon the major issues that have prevented a more prevalent use of the gas, such as the fact that the infrastructure of natural gas is more costly since it is transported though pipelines whereas other energy sources such as oil and coal have flexible systems that use trains, trucks and ships. In addition, the powerful lobbies of the coal and oil businesses, along with the inertia in the congress to pass a national climate change bill further dampens incentives for these industries to invest in natural gas, despite its various attractive qualities. We also include discussions of policy proposals to incentive greater use of natural gas in the future.
Introduction
Natural gas is formed in the earth’s crust as a result of transformation of organic matter due to heat and pressure of overlying rock. The gas hydrocarbons can also be produced as a result of microbial decomposition of organic substances and due to reduction of mineral salts [1]. Some of these gases are released into the atmosphere or hydrosphere while the rest accumulates in the upper layers of the earth’s crust.
The composition of natural gas varies depending on a number of factors like the origin, location of deposit and geological structure. Natural gas mainly consists of saturated aliphatic hydrocarbons like methane. Components such as carbon dioxide, hydrogen sulfide, nitrogen and helium constitute an insignificant proportion of natural gas composition. Natural gas is the cleanest of all fossil fuels and the main products of combustion of natural gas are carbon dioxide and water vapor. The combustion of natural gas releases very small amounts of nitrogen oxides (NOx), sulfur dioxide (SO2), carbon dioxide (CO2), carbon monoxide (CO), other reactive hydrocarbons and virtually no particulate matter. Coal and oil are composed of much more complex molecules and when combusted, they release higher levels of harmful emissions such as nitrogen oxides and sulfur dioxide. They also release ash particles into the environment. Table Table11 summarizes the different chemical emissions of competition fuels.

Explanation:
Fossil fuels, coal, oil and natural gas, are a non-renewable source of energy. Formed from plants and animals that lived up to 300 million years ago, fossil fuels are found in deposits beneath the earth. The fuels are burned to release the chemical energy that is stored within this resource. Energy is essential to modern society as we know it. Over 85% of our energy demands are met by the combustion of fossil fuels. Fuel is one of the most used earth product because in the entire world fuel energy is used to make a lot of important things such as vehicles gas, cells, etc. Fuel is any material that can be used to generate energy to produce mechanical work in a controlled manner and the processes used to convert fuel into energy include chemical reactions, such as combustion, and nuclear reactions, such as nuclear fission or nuclear fusion. Fuels are also used in the cells of organisms in a process known as metabolism. Hydrocarbons are by far the most common source of fuel in current use, but many other substances can be used as well. The most interesting case about fuel energy is how it was create or how human being in the past thousand years has the incredible idea to perform energy source, fuel energy was first starts with wood. It was one of the first fuels used by humans and is still the primary energy source in much of the world. These discover was performed by home erectus near 2 million years ago. A very important thing to say is that without fuel, our technology never will be developed because without that, cars, airplanes and all types of vehicles will not work.
Fossil fuels exist long before dinosaurs roamed the Earth. These are made up of plant and animal matter. When plants and animals died, their bodies decomposed and were buried under layers of earth. Millions of years later we have the three forms of fossil fuel: Oil, Natural gas and Coal. The advantages of fossil fuels is that they produces a lot of electricity especially coal, its cheap, transporting coal and gas is easy and power station that run on gas are very efficient and the disadvantages is that burning fossil fuels produces carbon dioxide which result in greenhouse gases that mean global warning alert, burning coal produce more carbon dioxide than gas and oil and it also produces sulphur dioxide that causes acid rain. According to scientists burning fossil fuels produces 20 billion of carbon dioxide every year and the earth natural process can only absorbs 20 billion tons of carbon dioxide and the remaining carbon dioxide goes to the atmosphere and contributes to global warning. The oil is found way down in the ground, usually between layers of rock. To get oil out, a well is dug. Digging a well is like putting a straw into a can of pop. The oil is then pumped out of the ground, just like when you suck pop up the straw. Oil is carried in pipelines and large tanker ships. A refinery changes the oil into products like gasoline, jet fuel and diesel fuel. It’s also burned in factories and power plants to make electricity Natural gas is made out of methane, which is a simple chemical compound made up of carbon and hydrogen atoms and this gas is highly flammable. Natural gas is found near oil in the ground. It’s pumped, just like oil, from wells that tap into the source and send it to large pipelines. Because you can’t smell or see natural gas, it is mixed with a chemical to give it a stinky smell like rotten eggs. For thousands of years man has depended on fossil fuels as his primary energy source.
