Pro fracking essay


pro fracking essay

plenty of gas and oil left thanks to the improved method of extraction, the need to find alternative energy sources is drastically reduced. This horizontal drilling has enabled engineers to inject millions of gallons of high-pressure water directly into layers of shale to create the fractures that release the gas. The fact that gas companies do not always disclose the composition of all fracking and drilling compounds makes it difficult to monitor for injected chemicals in streams and groundwater. Pennsylvania has also seen instances of methane leaking into aquifers in regions where shale-gas drilling is ongoing. Chemicals added to the water dissolve minerals, kill bacteria that might plug up the well, and insert sand to prop open the fractures. And while the natural gas produced by fracking does add greenhouse gases to the atmosphere through leakage during gas extraction and carbon dioxide release during burning, it in fact holds a significant environmental advantage over coal mining. Nowhere in the state have fracking compounds injected at depth been shown to contaminate drinking water. Anna Meyendorff is a faculty associate at the International Policy Center of the Ford School of Public Policy at the University of Michigan, and a manager at Analysis Group.

Pros, there are enough fossil fuels locked in bedrock shale formations under North American soil to make the United States energy independent, and a net exporter of oil and gas, in the near future. Companies are not required to disclose the chemicals they use, or the formula of the mixture, in the process. This means that we have more gas and oil to use for cooking, heating and powering out cars, for instance.

But trucking and storage accidents have spilled fracking fluids and brines, leading to contamination of water and soils that had to be cleaned. Water supplies in areas where fracking has recently taken place have tended to show an increased amount of dangerous chemicals. However, access to more gas may mean that we start to use more gas, and the burning of gas, less carbon dioxide is released into the atmosphere. They also claim that drilling for oil and gas is nothing new: weve been drilling for oil and gas for decades. New fracking technologies allow for the extraction of more gas, thus contributing more to climate change than previous natural gas extraction. In addition to these local effects, natural gas extraction has global environmental consequences, because the methane gas that is accessed through extraction and the carbon dioxide released during methane burning are both greenhouse gases that contribute to global climate change. An Encana well on state forest land not far from the Manistee River headwaters. Access to More Gas and Oil: Because fracking can reach to depths that other extraction methods cannot, we now have access to many more natural deposits of gas and oil than we ever did before.
