What’s Power Worth? When we think about air pollution and its sources we generally call to mind the things we see and smell daily. We recall the stench of diesel fumes, the plumes of automobile exhaust, or maybe the belching smoke from factories. Instead of these common culprits, maybe we should instead think about the light switch, the computer, the television, or maybe our air conditioners. We use these items everyday without a thought to the possible ramifications. These familiar household items contribute more to air pollution in our community than all of the aforementioned polluters combined. Their use requires electricity and that electricity is provided by power plants.
Electricity producing power plants are the largest source of air pollution nationwide (Izaak).
More than half of the nation’s power plants produce their electricity by burning coal. These coal-fired plants in particular are responsible for the majority of the most dangerous pollutants emitted by the electric power industry. According to the Environmental Protection Agency (EPA), coal-fired plants generate, “96 percent of sulfur dioxide emissions, 93 percent of nitrogen oxide emissions, 88 percent of carbon dioxide emissions, and 99 percent of the mercury emissions” emitted by the entire power industry (sierra club).

The power industry’s emissions result in ozone smog, reduced visibility conditions, and acid rain. Additionally, their released mercury is toxic and is absorbed by humans through the consumption of fish. “More than 70 percent of fish advisories issued [are] for mercury contamination” (sierra club).
Mercury can have devastating health consequences for children and women of childbearing age.
According to the American Lung Association, “Children are the most susceptible to the detrimental effects posed by air pollutants [… ]. In Virginia, 1, 256, 936 children live within 30 miles of a power plant” (Clear).
These close-in areas feel the greatest health impacts.
The environmental and human health hazards produced by coal-fired power plants are not a new revelation. The Government recognized decades ago the serious impact of all fossil fuel burning industries. Finally, in 1970, the Environmental Protection Agency was formed. Later that same year Congress passed the Clean Air Act with the intention of significantly reducing airborne pollutants. According to Federal officials, in the past 35 years “emissions of pollutants have dropped 51 percent nationwide” (Springston).
Unfortunately, when the Clean Air Act was created, a loophole was included that “grand fathered” the electric industry.
Pre-existing plants were exempted because Congress believed that their useful life was only 30 to 40 years. They believed it would be cheaper to replace them as they aged than to force compliance. These power plants have well exceeded their life expectancy with the majority continuing operation today. Right here in the Metro Richmond area, we have the largest coal-fired electricity plant in Virginia. Built in 1944, the Chesterfield Power Plant, also known as the Dutch Gap Power Plant, is recognized as Virginia’s biggest power plant air polluter.
The Essay on Power Coal Solar Reliable
Based on the current technology regarding power sources we believe that Australia's total power usage should be divided between these four sources using the percentage specified (reasons why are listed below): Nuclear Power - 50%Coal Power - 25%Solar Power - 15%Wind Power - 10%Nuclear Nuclear should generate majority of the power because it is a reliable power source and unlike coal generators, it ...
Because it is physically the largest coal-fired plant in Virginia, it emits far more pollutants than any other. The sulfur dioxide produced by Dutch Gap is 40 times the amount released by the 10-year-old Clover Power Plant in Halifax Clearing).
According to the Virginia Department of Environmental Quality, “In 2003 [… ] the plant released into the air 80, 706 tons of sulfur dioxide (tops in Virginia), 14, 972 tons of nitrogen oxides (tops again), and 1, 098 tons of tiny particles such as soot” (Times-Dispatch, Clearing).
These emissions make the Dutch Gap area one of the most concentrated pollution “hot-spots” on the East Coast. Accordingly, the EPA has determined, “the ozone in the Richmond area [is] too high for the public’s health” (Springston).
The news coming out of Chesterfield is not all bad. Although “grand fathered” from complying with the federal Clean Air Act, steps are being taken to clean up Dutch Gap’s emissions. Since 2003, the plant’s nitrogen oxide release has fallen by 8, 300 tons Clearing).
This has been accomplished even though coal consumption by the plant has increased to “100-car train-loads of coal a day, or 10, 000 tons” Clearing).
While complying with all federal standards, the Chesterfield Power Plant is currently taking the initiative to drastically reduce emissions.
According to spokesman Dan Genes, “Virginia Power [has] spent $225 million to install nitrogen-oxide controls” [at Dutch Gap]. “These devices can remove 90 percent of nitrogen oxides” Clearing).
Additionally, the company has voluntarily agreed to spend $1. 2 billion to add sulfur dioxide devices called “scrubbers” to its eight coal-fired plants Clearing).
It appears that Virginia Power is very conscious of its role in the community and is taking good faith steps to improve its standing. The question that begs to be answered is if we know all of the health and environmental harm done burning coal, why is it used? The answer is simple; cost.
Years ago the American public began strongly favoring the cleaner fuel of the future; natural gas. As a result, coal’s share of the electricity market began steadily dropping. But now price volatility in the gas market has rekindled interest in coal. Just last year it was reported that, “coal costs for utilities were, on average, more than 4 times cheaper than natural gas” (Brogan).
The Essay on The Advantages Of Coal Fired Power Plant
We Students had an opportunity to learn about the functions, the misconceptions and the advantages of having a Coal-Fired Power Plant as the source of our daily need of electricity. We had conducted a symposium with the representatives of the company (Panay Electric Company Inc.) last Thursday, October 19,2011. And now we know the answers behind every inquisitions of the people of Panay region, ...
So despite the risks, communities are looking to coal to provide a cheaper, more stable source for energy supplies. Another reason coal is still used is it’s abundance.
Coal usage greatly reduces our dependence on foreign fuels. While it is fact that natural gas is cleaner, the U. S. has only 3 to 4 percent of the world’s supply. By contrast, we currently own “250 years of coal reserves” which is about “one-quarter of the world’s known supply” (Smith).
The Dutch Gap Power Plant, like many coal-fired plants nationwide is cleaning up its act.
That’s a good thing because according to the Department of Energy, “by 2020 the United States is expected to consume about 22 percent more coal than today” (McNamara).
Luckily there have been vast improvements in coal burning technology that will allow us to take advantage of this abundant resource with less harm to the environment. But, we ” re not there just yet. The bottom line is there are no benign fuel sources. We have to weigh health and environmental concerns against economics. Based on our priorities, a decision has to be made as to which is most important to us.
Only then will we be able to determine the price we are willing to pay for our electricity. Works Cited Brogan, Pamela. Coal-Fired Plants Raise Health Concerns. 11 Aug.
