Built in 1923 as a coal-powered operation‚ the High Bridge plant‚ along with Riverside in Minneapolis‚ once formed the hub of Northern States Power Company‚ a predecessor to Xcel Energy. The original plant was replaced with a new natural gas fired generating facility starting in 2005 as part of Xcel Energy’s Metro Emission Reduction Project. The coal-fired plant was retired in 2007 and the new facility came on line in May 2008. (High Bridge Generating Station) One interesting feature about the

and 90% petrol. Though a 85% ethanol blend has started being used in Australia but is not available at all petrol stations. As a car fuel it is blended with petrol to decrease how fast petrol burns‚ extend petrol reserves and to reduce green house gas emissions. For Brazil the use of ethanol as a car fuel has been very successful as it has a very large starch industry. It is also beneficial to the country economically because the high concentration use of ethanol has replaced expensive oil imports

are opened and widened by injecting chemicals and liquids at high pressure”(Dictionary). This type of mining is used to extract natural gas and oil by drilling a mile or more below the surface. Fracking has been “commercially used for 65 years”(Introduction)‚ supplying Americans energy. Hydraulic Fracturing has allowed for the increase in supplies of oil and natural gas. It is currently the best and most efficient way to drill for these substances. Although this technique seems amazing‚ there are

tight‚ deep shale formations which have the potential to hold a lot of natural gas. The Marcellus Shale is large and covers a widespread amount of land area in the Northeastern United States. Researchers say that there is a potential for the Marcellus Shale formation to hold around 500 trillion cubic feet of natural gas in its shale deposits deep beneath the earth’s surface. The most controversial element of drilling for natural gas in the Marcellus shale is the use of hydraulic fracturing. In this

diminishing of conventional fuels across the world‚ governments and companies are looking to unconventional fuel resources. This means the fuel is extracted via another method then the conventional well strategy. These resources include fracturing of oil and gas source rocks‚ methane hydrates‚ tar sands and coal seam gasification. There are benefits such as energy security and economic growth associated with these resources. However‚ there are environmental disadvantages which may prove detrimental to sustainability

editor‚ Ever wonder why earthquakes are caused? Why does water in certain areas smell or taste like a chemical gas? The most likely reason for both of these effects is fracking. Hydraulic fracturing‚ as known as fracking‚ is the process of drilling and injecting fluid into the ground at a high pressure in order to fracture shale rocks to release natural gas inside (Dong). According to many recent research studies fracking is very harmful to the environment and shouldn’t be done here

the largest natural gas producer in the world. Higher production of shale gas has reduced energy prices over the last five years and has increased U.S. energy self-sufficiency. Since it is viewed as a relatively clean form of hydrocarbon-based energy‚ natural gas is an excellent way for the U.S. to bridge itself from current reliance on non-renewable natural resources to sustainable forms of renewable energy such as wind and solar power. The economic benefits of extracting shale gas with hydraulic

“Natural gas has an important role to play in the Northeast region and in our nation’s overall energy future.” Ed Rendell (NY Daily News). Fracking is a great way of getting natural gas; without fracking we wouldn’t have the gas need for energy like heating and power generation. Although Fracking makes pollution worse‚ it has many positive effects on people’s lives. Fracking is a way to get natural gas; natural gas is a cleaner source of energy. Another way fracking is good is it helps increase job

activity. The term pollution can be applied when the composition of something has been modified by the presence of one or more substances that either it cannot be used for a specific purpose or it is less suitable for that use than it was in its natural state. Nature pollutes water with leaves that fall off the trees and decay‚ animal waste‚ and oil seepages. 5. A major source of water pollution results from agricultural practices.
