The hazards in the coal mines and the benefits of nuclear energy

According to the Intergovernmental Panel on Climate Change, it is extremely likely that the rising global temperature trends since the midth century is dominantly due to human activity. No scientific organization of national or international standing disputes this. Furthermore, the US Department of Defense has officially stated that climate change poses a serious national security threat.

The hazards in the coal mines and the benefits of nuclear energy

Since they take so long to form, fossil fuels like coal and oil are nonrenewable.

The hazards in the coal mines and the benefits of nuclear energy

The process to generate energy from coal involves mining the coal, then transporting, cleaning and burning it.

Water heated by burning coal converts into steam and generates electricity.

Each stage of this process generates pollution. However, plans to reduce its pollution output may improve coal's standing as an energy source.

More than half of the nation's energy comes from coal, according to the U.

Nuclear Energy Use and Potential

This domestic energy source reduces the U. See References 3 Water Pollution Coal production requires large quantities of water, which affects the habitats of both aquatic and land-based wildlife as well as people who use these water resources.

Water that comes into contact with coal during extraction, cleaning, storage or energy production collects heavy metals like lead and arsenic. This polluted water can contaminate groundwater and nearby surface water sources.

See References 1 Air Pollution The process of burning coal for energy produces greenhouse gases and other harmful pollutants, including carbon dioxide, mercury compounds, sulfur dioxide and nitrogen oxides. Per unit of electricity, coal produces more pollution than any other fuel source, according to the U.

See References 2, Coal In addition, all steps of coal energy production -- mining, transportation and cleaning -- produce greenhouse gas emissions.

Coal contains methane, a combustible and potent greenhouse gas. Methane's global warming potential is 23 times greater than carbon dioxide. For safety reasons, methane vents into the atmosphere during coal processing.

See References 1 Additional Environmental Impacts Coal mining operations radically alter local ecosystems and wildlife habitats, by introducing roads, clearing trees and removing large sections of land.

Pollutants created by coal mining also contribute to acid rain, especially in the Appalachian region. In addition, burning coal generates ash, a solid waste that contains akali and metal oxides. Although new recycling processes use coal ash for building material, such as cement, the majority of ash contributes to landfills or remains in abandoned mines.

Additionally, many abandoned mines still contain harmful pollutants and continue to pollute the soil and nearby water sources.

Department of Energy and members of the private sector are developing cleaner processes for coal energy production. Their goal is to reduce or eliminate air and water pollution in newly designed power plants.

In addition, the Department of Energy is working to recapture greenhouse gases produced from converting coal into electricity.

More efficient energy extraction processes may also double the energy produced from coal over the next two decades.

Improved coal energy production will lead to increased employment opportunities for Americans.There are currently plans to develop the largest coal export facility in North America at Cherry Point, in northwest Washington state.

The Gateway Pacific Terminal, a project of Pacific International Terminals, would be owned by SSA Marine, which is owned by Carrix, partnered with Goldman grupobittia.com mined from the Powder River Basin by Peabody Energy .

Mining is the extraction of valuable minerals or other geological materials from the earth, usually from an orebody, lode, vein, seam, reef or placer grupobittia.com deposits form a mineralized package that is of economic interest to the miner.

Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock .

The concern is so great that U.S. officials who watch North Korea closely are continually monitoring the status of the North Korean space launch vehicle, whose status could suggest a pre-emptive nuclear strike against the United States.

Feb 01,  · Coal mining ruins the environment and puts the lives of people specially the coal miners in danger We cannot deny the fact that using coal energy is very important to us.

All of us want an affordable and reliable energy source which we can only get by using coal energy. Amid mounting concern about clean drinking water, rural Southern communities are getting squeezed: They can take much needed revenue from companies that want to store coal ash in their towns, or risk toxins in their groundwater.
