Natural gas is a fossil fuel formed when layers of buried plants and animals are exposed to intense heat and pressure over thousands of years. These animals and plants originally produced an energy that came from the sun, and it is stored in the form of carbon in natural gas. NG is combusted to generate electricity, allowing this energy to turn into power. Natural gas is a non-renewable resource. However, it is clean, convenient to use and easy to transport, therefore it is called as an ideal fossil fuel. Industrial users use almost half of the gas produced in the U.S.
In consequence to the increase of shale gas development and new technologies in recent years, the United States today has enough natural gas to power their nation for generations.

The combustion of natural gas produces carbon dioxide and nitrogen oxides at the power plant, however in small quantities than burning coal or oil. In the US, the average emissions rates from natural gas-fired generation are: 1135 lbs / MWh of carbon dioxide, 0.1 lbs / MWh of sulfur dioxide, and 1.7 lbs / MWh of nitrogen oxides [1]. When comparing with average air emissions from coal-fired generation, natural gas produces one percent as much sulfur oxides at the power plant, less than a third as much nitrogen oxides and half as much carbon dioxide. However, extracting, treating and transporting natural gas produces additional emissions.
Taking into account the higher carbon efficiency in the generation process, and adding together every benefit of using natural gas instead of other fossil fuels, the United States is dramatically switching its major fuel. The US has changed to reduce coal and increase natural gas ge...

...rable to supply disruption, price chances and trade deficits. Therefore, biodiesel is helping the US to reduce the petroleum importation, and consequently increasing jobs opportunities and improving the environment.
This fuel’s physical properties are very similar to those of petroleum diesel. One of the major advantages of using biodiesel is that it can be used in any pre-existing diesel engines. In addition, it reduces the GHG emissions by 57 per cent at least, in comparison to petroleum diesel, because the CO2 released from biodiesel burn is offset by the CO2 sequestered while growing the soybeans or other feedstock [3]. The biodiesel also helps to reduce tailpipe emissions of unburned hydrocarbons (HC), carbon monoxide (CO), sulphates, polycyclic aromatic hydrocarbons, nitrated polycyclic aromatic hydrocarbons, and particulate matter (PM), one of the US most dan
Fossil fuels, such as coal and oil, are Carbon rich compounds, the combustion of which produces Carbon Dioxide, a pollutant and a greenhouse gas. A large amount of energy is released during this process, which is why the pollutants off products are tolerated. This process occurs constantly throughout the world, in power stations, vehicles and cooking ovens, leading to an immense volume of CO2 being released every second, 50% of which is absorbed by oceans (Oce...

When the problems with gasoline use are considered, the catastrophic environmental effects are the primary concern. Automobile use consumes 70 percent of the United States oil supply and is responsible for one-third of the nation’s carbon emissions (Lovins 173). This results in pollution, global warming, and health problems for the people, plants, and animals. The search for alternative fuel is powered by the increasingly evident environmental problems and long-term health of the planet (Povey 17). Fortunately, reducing emissions globally is predicted to have a positive effect and offset previous harms (Backer).
Natural gas consists of gases existing in layers of sediment in either liquefied or gaseous form. It is a common non-renewable resource used for industrial, residential and commercial purposes. In particular, it is an important energy source for heating buildings, providing power to industry and as fuel for vehicles as well as for generating electricity
The United States spends billions of dollars on importing oil. This is represented as almost two-thirds of the country’s entire annual trade deficit. Now that there is more access to gas deposits, there is no need to rely on other countries around the world for fossil fuels. America can instead rely on their own resources to provide energy for the residents. America is already the world's largest producer of natural gas thanks to shell drilling and the country's sits on 2 of the world's largest gas fields gas production has soared 20 percent in five years in the United States now should have enough gas to last generations soon the nation will begin exporting gas and unimaginable possibility just a few years ago when energy supplies look set to run out in the construction of gas importing facilities was considered a matter of national urgency (Zuckerman, G.,
Biodiesel is considered an environmentally friendly alternative because it reduces the amount many toxic substances. Plants such as soybeans require carbon dioxide from the air to produce their stems, roots and leaves. During biodiesel production from soybean oil, carbon dioxide is produced and released in the atmosphere. Carbon dioxide is considered a green house gas (GHG). However, this cycle of GHG emission does not neccersarily contribute to the atmospheric carbon dioxide levels. This is because the next soybean crop will reuse the carbon dioxide emitted for its growth. Another important environmental benefit is that biodiesel reduces particulate matter (PM), hydrocarbon (HC) and carbon monoxide (CO) emissions. These benefits occur because biodiesel contains 11% oxygen by weight. Oxygen allows the fuel to burn better, resulting in fewer emissions from unburned fuel. And lastly, biodiesel fuels do not contain any sulfur and does not have an unpleasant smell when it is emitted from vehicles.
In the long, increased amounts of renewable energies are more likely to encourage the use of natural gas as a complementary source of power. Natural gas plants have the operational flexibility to vary their production rapidly, so this will allow them to be able to provide more reliability to the electric power system as it transitions to greater shares of renewable generation.

The recent advances in fracking technology has enabled us to reach previously unreachable reserves of natural gas and oil, “In 2008, after the breakthrough, the amount of domestic natural resources surged to 2.5 quadrillion feet. In other words, in just one year's time, we expanded our access to domestic natural gas by 66 percent”(Simmons ) and these reserves are huge. They are estimated to contain enough natural gases to power America for hundreds

United States is known for their innovation towards alternative energy like solar power, wind power and nuclear power. However , these alternative energies are not completely beneficial towards the United States. For example, Hydrofracking; What is hydrofracking? Gas industries use hydrofracking to extract natural gases from shale ground in order to power Americans homes. When gas industries hydrofrack, they dig ten-thousand feet into the mantle of the earth and turn perpendicular to the t into shale layers with cement and steel casing to prevent leaks.
The diesel we use today is much “cleaner” than previous types. Clean diesel is a type of diesel fuel that is often referred to as ULSD. This acronym stands for Ultra Low Sulfur Diesel. This type of fuel is a more refined fuel than previous standard types of diesel. Although it is not the same as biodiesel, many people do not actually know the difference between “biodiesel” and “clean diesel”. Biodiesel is a fuel derived from biological substances which can include plants, plant oil, and animal fat. Even though biodiesel and clean diesel are two different things, they are usually mixed
...ch is used to replace natural gas. He also stated that, among the equipment used to burn the biofuel, the suspension burner have the ability to exceed 99% efficiency and whole-tree burner can reduce the cost of harvesting and handling woody fuels by about 35% (Brown, 2003). Moreover, the usage of bio-energy in long term is to provide a degree of ecological balance and climate change, avoid acid rain, reduce soil erosion and minimize water pollution (Gevorkian, 2007). Therefore, biomass is environmental friendly like solar energy. Based on the research that has been carried out regarding the synthesis of gas from biomass, the gas gasifies in the internal combustion engine. The relative energy density of synthesis gas is higher than the fossil fuel under certain conditions. In addition, the relative flame speed of synthesis gas can reduce the time for spark ignition.
The emission of green house gasses due to human activity contributes the most in increasing global warming. Today, fossil fuels are used as a source of energy for transportation, electricity, industrial process and to increase human comfort in this era. Over the last decade humans have created mass amount of industries. These industries have been burning fossil fuels such as coal, which release carbon dioxide and carbon monoxide; carbon dioxide absorbs heat that raises the temperature of the earth. More than 80% of carbon dioxide comes from tr...
Fossil fuels are an important part of life. When you turn on the lights, watch TV, or take a shower, the electricity that you are using is being generated by fossil fuels. The three types of fossil fuels are coal, crude oil, and natural gas. They all take millions of years to form, so they are considered to be “non-renewable”- eventually, the fossil fuels will all be used up. One dangerous biological effect of using fossil fuels is ocean acidification. Extracting and transporting fossil fuels can also be very dangerous. Environmentally damaging accidents such as groundwater contamination, land subsidence, and oil spills occur frequently. Global warming is another possible environmental effect. Fossil fuels have a crucial role in modern society, but since they are non-renewable and dangerous, we should reduce our dependence on them and explore alternative energy sources. Wind energy, hydroelectricity, and solar energy are some examples of renewable fuel sources. There are also many things that people can do everyday to save energy (and, in turn, conserve fossil fuels).
