Clean Coal: A Case Study

In the United States, 42 percent of the nation’s electricity is generated by burning coal as coal is cheap and plentiful.

Clean coal is proposed as being an emission cleaner form of regular coal, because it reduces the amount of sulfur-dioxide, and nitrogen oxide that is produced by burning coal. It does this by removing impurities from the coal that are contributing to the higher emissions within regular coal, which is created through “clean coal technology”. Clean coal is obtained just like regular coal through either mining it or by mountaintop removal. A technique called coal washing is used to remove impurities, such as sulfur and other unwanted minerals, by washing them in a liquid to remove them.

The U.S obtains more than 84% of its energy from fossil fuels including oil, coal and natural gas. This is because people rely on it to heat their homes, power industries, run vehicles, manufacturing, and provision of electricity. It is apparent that the country’s transportation industry highly depends on conventional petroleum oil, which is responsible for global warming, thus threatening economic opulence and national security. Apart from that, increasing consumption of fossil fuels have elevated health problems in the state, destroyed wild places, and polluted the environment. After conducting Environmental Impact Assessment, projections showed that the world energy consumption would increase by more than 56% between 2010 and 2040. However, fossil fuels will cater for more than 80% of the total energy used in 2040. Sadly, it will be a trajectory to alter the world’s climate, as well as, weaken the global security environment. Importantly, the rate at which the US relies on fossil fuels needs to reduce since it has adverse effects on the planet’s supplies. The society needs to realize that fossil fuels are nonrenewable, thus taking millions of years to form (Huebner, 2003). Notably, the country can reduce dependency on fossil fuels by practicing energy conservation and efficiency,

Clean coal technology usually addresses atmospheric problems resulting from burning coal. Historically, the primary focus was on sulfur dioxide and particulates, since it is the most important gas in the causation of acid rain. More recent focus has been on carbon dioxide (due to its impact on global warming) as well as other pollutants. Concerns exist regarding the economic viability of these technologies and the timeframe of delivery, potentially high hidden economic costs in terms of social and environmental damage, and the costs and viability of disposing of removed carbon and other toxic matter. More, the byproducts of coal power production range from fly ash sludge ponds full of mercury, arsenic, and sulfur in unlined ponds that can leak into the water supply.

The Alternative energy industry in the United States has been at a steady rate of growth for the past decade, however there is still controversy over the use of renewable energies, their impact on the economy, and their impact on the environment. As controversial as the topic is, the argument boils down to a moral need to support environmental regulations, and an economical need to sustain domestic growth in the Energy industry of the United States. Mainly, the question is can alternative energy effective replace fossil fuels? There are of course arguments for both sides of this question.

Carbon emissions are changing the planet for the worse. Energy production (mostly coal) is producing a one third of the US 's global warming emissions. Renewable sources produce little to zero percent. The balance of coal and renewable energy in the U.S. needs to be evened out with renewable techniques. Statistics from the Union of Concerned Scientist’s “Benefits of Renewable Energy Use” show that most renewable resources emit less than one pound of CO2E/kWh. These have significantly less of a carbon footprint than coal, which emits 1.4 to 3.6 lbs. CO2E/kWh or natural gas, which emits .6 to 2 lbs. CO2E/kWh. This impressive difference of carbon emissions between renewable and fossil fuel is the key to caring for our environment. A 2009 USC study found that if 25 percent of the US 's

We should invest in cleaner alternatives that will not only be better for us but the environment. Although coal is used for electricity, there are other ways to produce electricity like water power, wind generators, and solar energy. Water power, or hydropower is power that is derived from the weight of the water. Hydroelectric power plants use dams or rivers to store water to then release the water through turbines that spin it that produces electricity. Wind generators are like water power but instead of water its wind. Wind turbines converts the wind’s energy into electric energy. Solar energy is similar but the energy comes from the sun. Some people use solar energy for their homes so they save money and will not have to pay an electric bill. Instead of burning coal, there are other alternatives as stated

Oscar starts off by stating "Coal, the source of half the energy in the United States, has been dirtiest of all fossil fuels because it creates harmful emissions when burned." He goes on to talk about the new technologies that are being developed of clean ways to use coal. These technological advances "purify exhaust gasses as coal burns" which are called wet scrubbers. Low NOx burners prevent harmful emissions from happening in the first place. There is even a process called gasification, which avoids burning coal to

Nowadays, coal is still one of the greatest used energy to generate power in so many countries. Using coal in electricity generation is 93% in South African, 87% in Poland, 79% in China, 78% in Australia, 45% in USA, 41% in Germany, 58% in Israel etc. (Coal & Electricity) From the data above, even the developed countries use coal to generate power as the main source. In many developed countries, energy generation is still based on coal as a long-term source. In recent years, although there is an increasing number of equipment using gas and wind to generate the power, it is still lower than the proportion of coal-fired power generation. The reason why most countries choose coal as a main source to generate electricity, is that there are many advantages in using coal to generate electricity. First of all, coal is the

Jason Hayes, communications director for the American Coal Council says “the industry over the past few decades had invested over $100 billion in cleaning up emissions and it’s already been effective. All of the important noxious pollutants have decreased markedly over the last 30 to 40 years. We’ve been doing all of this on top of dealing with everything else.” Coal may not be green, but it is a source of energy American needs. It is cheap and efficient. Without coal, America wouldn’t be anywhere near where it is today. The coal mined here isn’t just used for energy. America’s

The narrative of clean coal has been propped up by the industries primary lobbyist group, the National Mining Association, with a budget of nearly twenty million dollars a year (Coniff). Lobbying is a natural part of the political process, but the issue becomes when the lobbying is disingenuous and the coal industry has zero intentions of implementing clean coal, based on the fact that no coal plants currently in the United States make use of any of the technology. Although the technology is still being developed, there are no future plans to implement it as well. On the other side, those who speak out against coal and clean coal are naturally groups concerned about the environment, such as the Environmental Protection Agency and green advocacy groups. They recognize that coal power plants are the primary contributor to greenhouse gas emissions in the United States and thus their emissions must be controlled (Eilperin and Mufson). They also believe even though limiting coal power plants will cost a great deal of money, the American people will have a net benefit due to lower public health costs as a result of air pollution while also benefitting globally by reducing greenhouse gas fueled climate change. Essentially, clean coal is pursued by those who have a vested commercial interest in its being as a mainstay of electricity generation, while those who oppose it are against the negative health and climate effects it

Coal power is the cheapest fuel to power the ever growing population with Australian mining industry still putting in billions of dollars into a vast amount of coal projects never the less coal power is a fossil fuel, a fuel which takes hundreds of year to form so the future of coal is undetermined. Coal is a reliable power source but one of the many concern with coal is the mining process used to remove it from the ground. Ecological effects are developing worries for the industry, with the carbon emissions possibly contributing to global warming.

In the matter of clean-coal technologies, Alex supported his position better. His information was all relevant to the discussion and his reasoning was sound and free of fallacies.

As the world population rises, we are using more and more energy and it is depleting faster than ever. Our fossil fuels (coal, oil and natural gas) will not last forever and at some point we will have to switch over completely to renewable energy sources. While most of the world still uses non-renewable energy sources, the future will rely on renewable energy and its applications. Right now, over 90% of the world still uses fossil fuels and developing countries even burn wood to generate energy. At the rate we are using our fossil fuels, they will not last us far into the 22nd century. Additionally, big consumers of fossil fuels like China, U.S., Russia, and India are creating large amounts of pollution and it is only increasing. For instance, India has major issues with pollution because of heavy traffic (which releases more fuel emissions into the air), the burning of biomass (wood and other organic matter), and runoff into lakes and rivers. Right now, our biggest goal should be to figure out how to implement more forms of renewable energy in our own society. We should start using renewable energy in America because: it is more environmentally friendly, opens up the job market, and improves the health of the public.

CO2 is the most significant greenhouse gas, which mainly comes from the use of fossil fuels. Many people feel that content of CO2 in the atmosphere is the main reason for manmade global warming. The main sources of CO2 emissions involve electricity generation, industrial processes, fumes from transportation and commercial buildings and use. Emissions of greenhouse gases, such as CO2, to the atmosphere are expected to cause even more of a significant change in global climate (Davison, 2007). The main focus to try to reduce the amount of carbon dioxide in the atmosphere is to reduce the amount that is released from coal-fired power plants. Greenhouse gas emissions that involve the productions of electricity come from natural gas production and coal-fired power plant operations. Natural gas production accounts for twenty-four percent and coal-fired power plant operations accounts for seventy-five percent, while the other one percent is caused by other electricity generation operations. The main reason why coal-fired power plants have a higher percentage of emissions is because the sulfur content of coal is much higher than that of other fossil fuels (Jarmaillo et al., 2007). This proves that there is a great need to find an alternative fossil fuel to use instead of coal. Although coal is easy to mine, transport and process for the electricity generation process, it is also the
