Hydraulic Fracking Issues
There has been a great deal of controversy over the technique called hydraulic fracking, which environmentalists and others have claimed it is a dangerous procedure to extract natural gas from the earth. The industry insists it is safe, and recently the Environmental Protection Agency issued research that indicates fracking can be safely done. What is hydraulic fracking? Fracking is a procedure in which water is injected under high pressure into a "bedrock formation," which in turn releases natural gas that has been trapped in rock formations (USGS). This paper points out the benefits of hydraulic fracking
Main Body of the Paper on Hydraulic Fracking
Fracking involves a process where water is mixed with chemicals and "fine sands, then pumped at extremely high pressure into the shale rock," which fractures the rock, according to the United States Geological Survey (USGS). Once the rock below the surface of the earth is fractured, it forms " ... pathways for the ... gas to reach the well"; the water is then recovered as well as the natural gas (USGS).
Why is natural gas a good solution to global...
Energy Information Administration (EIA) explains that burning natural gas for energy " ... results in fewer emissions of nearly all types of air pollutions and carbon dioxide" (EO2). Natural gas has less greenhouse gas emissions than coal or other petroleum products, in fact, for every million British thermal units (Btu) burned of natural gas about 117 pounds of carbon dioxide is produced (EIA). And carbon dioxide is the main culprit in climate change, which is causing the earth to warm up and is melting the ice fields, which in turn causes oceans to rise to dangerous levels in many areas of the world. Other pollutants that are emitted from burning fossil fuels include: mercury, coal ash, arsenic.
Comparing the 117 pounds of CO2 produced (per million Btu) by burning natural gas to other energy forms shows clearly the advantage of natural gas. By burning a million Btu of coal, over 200 pounds of CO2 is produced (EIA). Over the past ten years, about 81% of the new electrical generation systems have been powered by natural gas (Grace Communications, 2015). Also, the increase in supplies of natural gas helps to lower its price on the market. In fact In July, 2008, natural gas cost over $12 per MMBtu; but by July, 2015, because of the…
Greenhouse Gas Emissions in the Context Of Electricity Production There is much controversy in the contemporary society with regard to global warming, its causes, and the effects it is going to have on the planet. Greenhouse gasses emitted throughout recent centuries are believed to have seriously accelerated the global warming process, as they accumulate in the atmosphere and destroy the ozone layer to the point where it is no longer able
Capturing and Storing Energy: From Fossil Fuels to Renewable Resources One of the most interesting challenges in energy production is not how to find energy sources, which are abundant, but how to capture and store the energy that is available. For years, energy capture and storage has focused on the availability of fossil fuels and how those resources could be translated into usable energy sources. However, the demand for energy is
Future Supply and Demand of Natural Gas The technology developed in the United States has become available for application in other countries mainly through efforts of major service companies. Until the mid 1990s, Canada's gas production was predominantly from conventional gas formations. This conventional gas filled the available pipeline capacity and unconventional gas resources, which are more difficult to produce, were largely ignored. However, as pipeline capacity was expended and
Energy of the Future There is no doubt that petroleum and coal are the dominant energy sources of today. However, there is also no doubt that those two energy sources really need to fall by the wayside given how they pollute the earth and how they are ostensibly affecting the entire global climate in the form of greenhouse gases and the like. However, actively and completely replacing those two energy sources
Future of Renewable Energies While the reliance of the United States on natural resources and fossil fuels must give way to renewable and sustainable resources at some point, the ability to change to new technologies is not yet here and further efforts are needed to make the United States both energy-independent and free of fossil fuels. The USA is one of the greatest countries in the world. This is not just because

However, there seems to be a more conscious effort to go around the negative impact of consumption of energy by
