Glg 111 Unnatural Disaster? Coal project
1) Explain the following: Coal an Unnatural Disaster?
An unnatural coal disaster is one caused by human error or negligence, there have been many unnatural coal disasters from past to present such as Turtle Mountain in Canada .Normal erosion due to weather changes played a part in this unnatural disaster but the biggest factor was inadequate support beams .which in turn caused gigantic slab of limestone rock weighing 75millions tons broke free and crashed into the town below mowing over homes and killing 76 people. The Tennessee valley disaster, Tennessee Valley slurry impoundment burst freeing approximately 500 million gallons of toxic ash into the country side and the surrounding rivers and lake, this spill was forty times larger than the Exxon Valdez in1989 Tennessee is still trying to recover from this spill.
2) What are the benefits and consequences of the use of coal as a fossil fuel? A major advantage of fossil fuels is their capacity to generate huge amounts of electricity in just a single location. When coal is used in power plants, they are very cost effective. Coal is also in abundant supply. Power stations that make use of fossil fuel which can be constructed in almost any location. This is possible as long as large quantities of fuel can be easily brought to the power plants. Consequences
Pollution is a major disadvantage of fossil fuels. Fossil fuel releases greenhouse gasses (GHG) carbon dioxide when burned thereby causing a greenhouse effect. This is also the main contributory factor to the global warming experienced by the earth today. Power stations that utilize coal need large amounts of fuel. In other words, they not only need truckloads but trainloads of coal on a regular basis to continue operating and generating electricity. This only means that coal-fired power plants should have reserves of coal in a large area near the plants location. The present and on-going dependence of our global economy on fossil hydrocarbons for fuel, power, and materials processing thus poses a strong challenge to the goal of capping pollutants emissions Gasses fast enough and at an appropriately low level to avoid what are projected to be dangerous global average temperature increases during the next century and beyond. 3) Is coal a sustainable energy source? Explain.
“In response to regulatory requirements, the U.S. Department of Energy (DOE) initiated its original Clean Coal Technology Program, which consisted of five rounds of project funding. This program sponsored projects in the following areas: environmental control devices, advanced electric power generation, coal processing for clean fuels, and industrial applications.” Coal will play a chief role complementing renewable energy sources. It will be one of the key sources of energy to address gaps in wind and solar powered electricity, both of which include risks of irregular supply. Clean Coal Technology process of reducing emissions from plants using coal as needed to accomplish this which is called clean coal technology, is design to reduce emission and improve the proficiency and effectiveness of clean coal production of power plants by reducing pollution and decreasing the amount of coal consumed to produce power the technology. However In my opinion that has not been completely accomplished
4) What problems or issues exist when considering
Coal extraction (mining)?
The storage, disposal and handling of the byproducts of coal burning? Coal extraction problem s. land use issues, waste management, water and air pollution are all problems caused by coal mining, wild life and human deaths related to pollutant from coal mining Coal burning : pollution millions of tons of solid waste, including fly ash, bottom ash ,sludge, a sulfur dioxide removal process called flue –gas desulfurization which encompasses Mercury ,uranium, thorium,...
