Fossil fuels Bad




General / Laundry List

Using fossil fuels for electricity costs the U.S. more than $120 billion a year

“Report looks at hidden health costs of energy production”; Correspondent; McClatchy Newspapers; http://www.mcclatchydc.com/2009/10/19/77423/report-looks-at-hidden-health.html; Accessed June 23, 2014//



Generating electricity by burning coal is responsible for about half of an estimated $120 billion in yearly costs from early deaths and health damages to thousands of Americans from the use of fossil fuels, a federal advisory group said Monday.¶ A one-year study by the National Research Council looked at many costs of energy production and the use of fossil fuels that aren't reflected in the price of energy. The $120 billion sum was the cost to human health from U.S. electricity production, transportation and heating in 2005, the latest year with full data.¶ The report also looks at other hidden costs from climate change, hazardous air pollutants such as mercury, harm to ecosystems and risks to national security, but it doesn't put a dollar value on them.¶ "We would characterize our estimate as an underestimate," because it didn't include those other costs, said Jared Cohon, the president of Carnegie Mellon University and the chairman of the committee that produced the report.¶ The report says it's impossible to put a monetary amount on all the hidden costs of energy, in some cases because of a lack of information but also because the study had limited time and resources. It focused on the costs of air pollution on health.¶ Coal-fired power and motor-vehicle transportation accounted for roughly 99 percent of those costs. The other approximately 1 percent of the estimate was from heating for homes, buildings and industrial purposes, mostly from natural gas.¶ Electricity production accounted for $63 billion of the damages that weren't related to climate change. Coal-fired plants, which produce about half of the nation's electricity, accounted for $62 billion and natural gas, which produces 20 percent, produced less than $1 billion of the damages.¶ The report looks at the sulfur dioxide, nitrogen oxide and particulate emissions from 406 coal-fired plants in the lower 48 states, which produce 95 percent of the nation's coal-generated electricity.

Fossil fuel mining destroys whole ecosystems, producing waste and pollution that filters through the food chain


J. Hansen, et al., ‘13, “Earth Institute and Columbia University,  Assessing “Dangerous Climate Change”: Required Reduction of Carbon Emissions to Protect Young People, Future Generations and Nature,” PLoS ONE, 8(12): e81648, http://www.plosone.org/article/ info%3Adoi%2F10.1371%2Fjournal.pone.0081648, Accessed 5/2/2014

The ecological impact of fossil fuel mining increases as the largest, easiest to access, resources are depleted. A constant fossil fuel production rate requires increasing energy input, but also use of more land, water, and diluents, with the production of more waste. The increasing ecological and environmental impact of a given amount of useful fossil fuel energy is a relevant consideration in assessing alternative energy strategies. Coal mining has progressively changed from predominantly underground mining to surface mining, including mountaintop removal with valley fill, which is now widespread in the Appalachian ecoregion in the United States. Forest cover and topsoil are removed, explosives are used to break up rocks to access coal, and the excess rock is pushed into adjacent valleys, where it buries existing streams. Burial of headwater streams causes loss of ecosystems that are important for nutrient cycling and production of organic matter for downstream food webs. The surface alterations lead to greater storm runoff with likely impact on downstream flooding. Water emerging from valley fills contain toxic solutes that have been linked to declines in watershed biodiversity. Even with mine-site reclamation intended to restore pre-mined surface conditions, mine-derived chemical constituents are found in domestic well water. Reclaimed areas, compared with unmined areas, are found to have increased soil density with decreased organic and nutrient content, and with reduced water infiltration rates. Reclaimed areas have been found to produce little if any regrowth of woody vegetation even after 15 years, and, although this deficiency might be addressed via more effective reclamation methods, there remains a likely significant loss of carbon storage.


Coal extraction destroys ecosystems and produces toxic wastes

Strip mining, also known as mountaintop removal (MTR), flattens mountains and devastates ecosystems. In this process, forests are clear-cut to expose the tops of mountains, which are then blown off with explosives. Coal is extracted using large machinery and the unused soil and rock are dumped into adjacent valleys, filling them up and creating a flat landscape.¶ The coal companies are supposed to reclaim the land, but this rarely occurs. Even if it does, the mountain ecosystem can never be fully restoredMTR also produces massive amounts of toxic waste that must be stored in slurries, which may endanger nearby towns ¶ Toxic Waste¶ Both coal mining and burning generate enormous amounts of liquid waste in the form of slurry, containing carcinogenic compounds and toxic heavy metals. The slurry is stored in large lagoons that sometimes leak or break, resulting in slurry floods and water contamination.¶ Slurry spills happen all the time, but some of them are especially disastrous. In both 2000 and 2008, coal-slurry ponds in Kentucky and Tennessee burst, spilling more toxic waste into the surrounding communities than the Exxon-Valdez oil spill. In summer 2010, the EPA proposed regulating coal slurry (also known as coal ash) as hazardous waste for the first time. (Green America is currently running a campaign to supply public comment on this issue to the EPA.)¶ Fossil fuel combustion yields over 100 million tons of waste each year. [CATF]¶

Fossil fuels cause a host of environmental and health problems


UCS October 29, 2002(Union of Concerned Scientists) “The Hidden Cost of Fossil Fuels”; http://www.ucsusa.org/clean_energy/our-energy-choices/coal-and-other-fossil-fuels/the-hidden-cost-of-fossil.html; Accessed June 22, 2014//

But some energy costs are not included in consumer utility or gas bills, nor are they paid for by the companies that produce or sell the energy. These include human health problems caused by air pollution from the burning of coal and oil; damage to land from coal mining and to miners from black lung disease; environmental degradation caused by global warming, acid rain, and water pollution; and national security costs, such as protecting foreign sources of oil.¶ Since such costs are indirect and difficult to determine, they have traditionally remained external to the energy pricing system, and are thus often referred to as externalities. And since the producers and the users of energy do not pay for these costs, society as a whole must pay for them. But this pricing system masks the true costs of fossil fuels and results in damage to human health, the environment, and the economy.¶ Environmental Impacts of Fossil Fuel Use¶ Many of the environmental problems our country faces today result from our fossil fuel dependence. These impacts include global warming, air quality deterioration, oil spills, and acid rain.¶ Global Warming ¶ Among the gases emitted when fossil fuels are burned, one of the most significant is carbon dioxide, a gas that traps heat in the earth's atmosphere. Over the last 150 years, burning fossil fuels has resulted in more than a 25 percent increase in the amount of carbon dioxide in our atmosphere. Fossil fuels are also implicated in increased levels of atmospheric methane and nitrous oxide, although they are not the major source of these gases.¶ Since reliable records began in the late 1800s, the global average surface temperature has risen 0.5-1.1 degrees Fahrenheit (0.3-0.6 degrees Celsius). Scientists with the Intergovernmental Panel on Climate Change concluded in a 1995 report that the observed increase in global average temperature over the last century "is unlikely to be entirely natural in origin" and that "the balance of evidence suggests that there is a discernible human influence on global climate."¶ Climate scientists predict that if carbon dioxide levels continue to increase, the planet will become warmer in the next century. Projected temperature increases will most likely result in a variety of impacts. In coastal areas, sea-level rise due to the warming of the oceans and the melting of glaciers may lead to the inundation of wetlands, river deltas, and even populated areas. Altered weather patterns may result in more extreme weather events. And inland agricultural zones could suffer an increase in the frequency of droughts.¶ Air Pollution ¶ Clean air is essential to life and good health. Several important pollutants are produced by fossil fuel combustion: carbon monoxide, nitrogen oxides, sulfur oxides, and hydrocarbons. In addition, total suspended particulates contribute to air pollution, and nitrogen oxides and hydrocarbons can combine in the atmosphere to form tropospheric ozone, the major constituent of smog.

A2: Coal Good turns - NU

Most coal plants are no longer economically competitive


Union of Concerned Scientists January 14, ’14, “Smart Energy Solutions: Decrease Coal Use,” http://www.ucsusa.org/clean_energy/smart-energy-solutions/decrease-coal/, Accessed 6/25/2014

A significant number of U.S. coal-fired power plants are old, inefficient, and no longer economically competitive. They are ripe for retirement — it simply makes no financial sense to keep them running when cheaper, cleaner alternatives are available.

Burning Coal Wastes Money

The costs of coal go beyond just its environmental impacts. Coal also incurs substantial economic costs for the states that rely on it most, especially when they import large amounts from other states or foreign countries.

Renewables are starting to outcompete coal now

A significant number of U.S. coal-fired generators are old, inefficient, dirty, and no longer economically competitive. Simply stated, they are ripe for retirement and should be considered for closure.

America’s coal power fleet is facing an increasingly uncertain economic future. Growing competition from cheaper, cleaner alternatives — including natural gas and renewable energy sources such as wind and solar — is making it harder for these generators to produce energy economically.



Coal Bad – General / Laundry List

Coal burning releases harmful emissions, kills species, and contaminates environment


EPA September 25, 2013 (U.S. Environmental Protection Agency),

“Coal”; http://www.epa.gov/cleanenergy/energy-and-you/affect/coal.html; Accessed June 22, 2014//



When coal is burned, carbon dioxide, sulfur dioxide, nitrogen oxides, and mercury compounds are released. For that reason, coal-fired boilers are required to have control devices to reduce the amount of emissions that are released.¶ The average emission rates in the United States from coal-fired generation are: 2,249 lbs/MWh of carbon dioxide, 13 lbs/MWh of sulfur dioxide, and 6 lbs/MWh of nitrogen oxides.¶ Mining, cleaning, and transporting coal to the power plant generate additional emissions. For example, methane, a potent greenhouse gas that is trapped in the coal, is often vented during these processes to increase safety ¶ Large quantities of water are frequently needed to remove impurities from coal at the mine. In addition, coal-fired power plants use large quantities of water for producing steam and for cooling. When coal-fired power plants remove water from a lake or river, fish and other aquatic life can be affected, as well as animals and people who depend on these aquatic resources.¶ Water Discharges¶ Pollutants build up in the water used in the power plant boiler and cooling system. If the water used in the power plant is discharged to a lake or river, the pollutants in the water can harm fish and plants. Further, if rain falls on coal stored in piles outside the power plant, the water that runs off these piles can flush heavy metals from the coal, such as arsenic and lead, into nearby bodies of water. Coal mining can also contaminate bodies of water with heavy metals when the water used to clean the coal is discharged back into the environment. This discharge usually requires a permit and is monitored. For more information about these regulations, visit EPA's Office of Water website ¶ The burning of coal creates solid waste, called ash, which is composed primarily of metal oxides and alkali. On average, the ash content of coal is 10 percent. Solid waste is also created at coal mines when coal is cleaned and at power plants when air pollutants are removed from the stack gas. Much of this waste is deposited in landfills and abandoned mines, although some amounts are now being recycled into useful products, such as cement and building materials.¶ Soil at coal-fired power plant sites can become contaminated with various pollutants from the coal and take a long time to recover, even after the power plant closes down. Coal mining and processing also have environmental impacts on land. Surface mining disturbs larger areas than underground mining.¶ In the United States, coal consumption in 2003 was just over 1.1 billion tons. Coal reserves in the United States stand at 268 billion tons, of which 43 percent are in surface mines. The three major coal-producing states are Wyoming, West Virginia, and Kentucky.

Coal pollutes and damages environment from mining to emissions


EESI 2014 (Environmental and Energy Study Institute) “Fossil Fuels”; http://www.eesi.org/topics/fossil-fuels/description; Accessed June 23, 2014//

Coal is primarily used to generate electricity and is responsible for 42 percent of the electric power supply in the United States in 2011 (down from half in 2007). The United States produces around 14.1 percent of the world’s total with Wyoming, West Virginia, Kentucky, Pennsylvania, and Texas leading in production. China is the global leader in coal production, responsible for almost 50 percent of world supply.¶ The combustion of coal releases air pollutants such as acid rain-inducing sulfur dioxide, nitrogen oxides (NOx), and mercury. The mining process can also be very damaging to the environment, often resulting in the destruction of vegetation and top-soil. Rivers and streams can also be destroyed or contaminated by mine wastes. The combustion of coal is responsible for 36.5 percent of the greenhouse gas emissions in the United States.¶ The premise of "clean coal" has recently been promoted as a way to use this abundant energy source without damaging the environment. Carbon capture and storage (CCS), where carbon is separated from coal and injected underground for long term storage, could theoretically be used to mitigate the coal industry's greenhouse gas emissions. However, CCS has yet to be proven as a safe or realistic way to reduce greenhouse gas emissions from commercial power plants and the environmental and health costs of mining remain.

Coal—Systemic Impacts

Burning coal emits deadly toxins that kill over 30,000 a year


Green America 14

“Coal: Why It's Dirty”; http://www.greenamerica.org/programs/climate/dirtyenergy/coal/whydirty.cfm; Accessed June 22, 2014//

Air Pollution¶ Pollution from coal-burning power plants causes an estimated 30,000 deaths a year in the United States – that’s more than drunken driving, AIDS, or homicides. [CATF]¶ Fine particles and oxygen-blocking gases produced when coal is burned are linked to asthma, heart disease, emphysema, and lung cancer.¶ NOx reacts with volatile organic compounds (VOCs) and sunlight to produce smog, which causes many kinds of health problems when inhaled.¶ Toxic Emissions¶ “Coal-fired power plants are the largest single man-made source of mercury pollution in the U.S.” [EPA]¶ Emissions from coal-fired power plants have been found to contain 67 air toxins that are either known or suspected carcinogens and neurotoxins that can cause a number of developmental and respiratory problems. The most dangerous of these toxins is mercury.¶ Mercury is released when coal is burned and falls to the earth, ultimately making its way into the water, contaminating fish. Humans become contaminated from eating the fish. 47 states and territories issued fish consumption advisories for mercury in 2004. Mercury is most dangerous as a developmental toxin, causing brain damage, mental retardation, blindness, and other problems in fetuses and breastfeeding babies of contaminated mothers.


A2: Alt. Cause China

Already solved only a question of what the US will do


Phillips 6/3

Ari Phillips is reporter for ClimateProgress.org. A native of Santa Fe, New Mexico, he received his bachelor of arts in philosophy from the University of California, Santa Barbara, and dual master’s degrees in journalism and global policy studies from the University of Texas at Austin. He previously held internships with The Texas Observer, the Institute for Global Environmental Strategies in Japan, and the Center for Global Energy, International Arbitration, and Environmental Law at The University of Texas School of Law, “One Day After U.S. Announces Emissions Target, China Says Carbon Cap Is On The Way”, Think Progress, Jun. 3, 14 http://thinkprogress.org/climate/2014/06/03/3444105/china-carbon-cap-2/ Accessed 6/22



One day after the United States proposed rules to limit the amount of carbon emitted from existing power plants, China said it will limit its total CO2 emissions for the first time, likely starting in 2016 with the announcement of their next five-year plan. China, the world’s biggest greenhouse gas emitter, and the U.S., the second biggest, account for about 42 percent of global emissions. The back-to-back signalling of serious domestic efforts to reduce emissions could signal a much-needed boost of momentum at the upcoming U.N. climate talks in an effort to establish a post-Kyoto global commitment. However the statements, which come from He Jiankun, chairman of China’s Advisory Committee on Climate Change, are without specific detail or commitment and merely offer speculation on China’s approach to regulating GHGs going forward.

According to Reuters, He told a conference in Beijing on Tuesday that an absolute cap on carbon emissions will be introduced later this decade.”The government will use two ways to control CO2 emissions in the next five-year plan, by intensity and an absolute cap,” He said.



The cap will be the first time China, which has been plagued by air pollution from coal-burning power plants as well as the impacts of climate change in the form of heat and drought, has publicly committed to limiting emissions. Right now China is only attempting to limit “carbon intensity” which means as the economy expands carbon emissions can continue to grow. A peak on overall emissions would help separate economic growth from greenhouse gas emissions.

“What’s going on is that the Chinese government has publicly announced that they are in the process of drawing up new plans for the next five-year plan,” said Melanie Hart, director of the China energy and climate policy program at the Center for American Progress. “These plans are macro-level guides for the economy, including energy and climate:”



What Beijing’s climate modelers are trying to do now is to figure out when Chinese emissions will naturally peak under a business as usual scenario. They are tracking past emission patterns in Europe, the United States and other developed nations to figure out at what point in the industrialization process emissions naturally peak and when that is likely to happen for China. It is not yet clear whether Beijing will use that information to set an ambitious target that drives their nation to peak earlier than their business as usual scenario. That is something the international community should keep a close eye on.

Hart said that if Chinese government establishes a national peak year for Chinese emissions, “it could be a game changer.”

“Once they have that on paper they’ll have to stick to it.”

Even though He’s words come on the heels of the U.S. announcement to cut GHGs from power plants, the two are not likely related. China is worried about domestic jobs and economic goals and still views itself as a developing country when it comes to climate goals. While China wants to be a leader among developing countries, it still falls on the U.S. to lead the overall effort — or to at least live up to prior commitments. The U.S. announcement is a big deal in part because it shows that the country will live up to its 2020 targets, making it harder for developing countries like China to hide behind lagging efforts in developed countries.

China has been slowly rolling out local and regional initiatives to reduce dirty fossil fuel production while at the same time encouraging the growth of renewable energy sources. Coal still accounts for about two-thirds of China’s energy production, and establishing a peak emissions year must align strongly with a peak year for coal-burning power production. Even as wealthier residents along the eastern coast demand cleaner air, inland there are millions of Chinese simply looking to improve quality-of-life through access to electricity and basic living standard improvements.

This announcement is both the latest in a series of domestic carbon-reduction efforts from China and one of the boldest as the stakes of the international climate discussions unfold. As the true impacts of climate change move ever more into the present, the necessity of cooperation is just as apparent as the importance of leadership. Hart said that China pays very close attention to climate policies that work or don’t work in other countries as they attempt to craft their own responses.

The U.S. is putting their money where their mouth is, they are here to play ball,” said Hart. “This creates a greater push for other nations to be ambitious.”



Coal Bad – Hurts economic growth




Fossil fuels cost USA more than $120 billion

Coal Bad – CO2 / Warming

Burning coal for electricity jeopardizes the entire planet—80% of CO2 emissions


Union of Concerned Scientists January 14, ’14, “Smart Energy Solutions: Decrease Coal Use,” http://www.ucsusa.org/clean_energy/smart-energy-solutions/decrease-coal/, Accessed 6/25/2014

Coal is a dirty energy source. It pollutes our environment with toxins, produces a quarter of U.S. global warming emissions, and accounts for a whopping 80 percent of all carbon emissions produced by power generation nationwide. When we burn coal for electricity, we place our health, our environment, and our planet at risk. It’s time to reduce our dependence on this polluting energy source.

Coal-fired electricity plants are the leading source of CO2 emissions


Union of Concerned Scientists ’12, “Environmental impacts of coal power: air pollution,” Accessed 6/25/2014, http://www.ucsusa.org/clean_energy/coalvswind/c02c.html

Coal plants are the nation’s top source of carbon dioxide (CO2) emissions, the primary cause of global warming. In 2011, utility coal plants in the United States emitted a total of 1.7 billion tons of CO21.  A typical coal plant generates 3.5 million tons of CO2 per year2. Burning coal is also a leading cause of smog, acid rain, and toxic air pollution. Some emissions can be significantly reduced with readily available pollution controls, but most U.S. coal plants have not installed these technologies.

Coal burning is toxic and floods atmosphere with CO2

Coal ash is a toxic by-product of burning coal, which contains high levels of arsenic, chromium, selenium, and barium. When coal ash ponds spill local waterways become so contaminated as to lose literally all of the aquatic life to the coal-ash poisons. The EPA has recently launched a public comment period on its proposal to regulate coal ash as a hazardous waste. Coal Basics¶ Coal is a hydrocarbon and a fossil fuel – remains of plant and animal (carbon-based) materials that have been compressed for millions of years that, when burned, release energy.¶ Because coal is a form of trapped carbon, burning it releases the carbon as carbon dioxide (CO2).¶ Because coal takes millions of years to form and humans take only minutes to break it down, it is a non-renewable energy source.¶ Because it takes only minutes to release carbon that has taken millions of years to store, we are upsetting the natural carbon cycle dramatically and flooding the atmosphere with CO2.

Acid Rain Scenario

Acid rain damage is recovering now, but further emissions reductions are key


USGS 1/19/’12 U.S. Department of the Interior, “U.S. Geological Survey Acid Rain Study Show Substantial Decreases, But More Progress Is Needed,” http://www.usgs.gov/newsroom/article.asp?ID=3078#.U6szMfk8CSo, Accessed 6/25/2014

Based on models which analyze various emission scenarios, the report concludes that beyond current SO2  and NOx emission levels, future emission reductions would likely promote additional and more widespread recovery as well as to prevent further acidification in some U.S. regions.

"The principal message of this report is that the Acid Rain Program has worked. The emissions that form acid rain have declined and some U.S. areas are beginning to recover," said Doug Burns, lead author and director of the NAPAP and also a U.S. Geological Survey hydrologist. "However, some sensitive ecosystems are still receiving levels of acid rain that exceed what is needed for full and widespread recovery.  We have every reason to believe that recovery will continue with further decreases in emissions which is why further emission reductions would be beneficial."

Acid rain tramples on biodiversity in multiple ways


USGS 1/19/’12 U.S. Department of the Interior, “U.S. Geological Survey Acid Rain Study Show Substantial Decreases, But More Progress Is Needed,” http://www.usgs.gov/newsroom/article.asp?ID=3078#.U6szMfk8CSo, Accessed 6/25/2014

Based on models which analyze various emission scenarios, the report concludes that beyond current SO2  and Acid rain occurs when emissions of SO2 and NOx react in the atmosphere with water, oxygen, and oxidants to form acidic compounds. These emissions may be transported hundreds of miles away from their emitting sources, and have the potential to impact large areas and populations.



Together these acidic compounds can damage human health, and in addition to degrading air quality and visibility, can cause further environmental damage, including acidification of lakes and streams, harm to sensitive forests and coastal ecosystems, and accelerate the decay of building materials. Adverse ecological impacts from acid rain include reductions in biodiversity, an increased risk of damaging forest fires, and increased susceptibility of trees to pests, disease, and winter temperatures.

Extinction

In order for 7.1 billion people (and growing to 8 billion by 2023) to exist on Earth, we require old growth forests and tropical jungles to provide fresh water, white clouds to reflect incoming solar radiation at the tropics, oxygen and habitats for all the critters.  Scientists must be allowed to study these magnificent ancient forests to understand how they work. Accordingly, a moratorium on logging any ancient forests on Earth is requisite. Wild forests contain untold cancer fighting and pain-relieving medicines. In addition, big trees are the most remarkable carbon warehouses to have ever evolved on our planet! If we deprive a species of what it needs to live, it becomes extinct. Globally, over the past 50 years, thousands of species have gone extinct due to human population pressures and destruction of habitat from mining and logging. Conservation biology is a relatively new, exciting and challenging branch of science. The discipline is charged with the responsibility of maintaining biological diversity or the tapestry of life on our planet.  Protecting all remaining wild ecosystems brimming with biodiversity -- in face of rapid human-induced climate change -- is our salvation.

Acid Rain – Coal Links

Coal plants are a biggest cause of acid rain


A. Lynn Cochran, ’14, “Why Is Acid Rain More of a Problem Today Than It Was 100 Years Ago?,” Seattle Post-Intelligencer, http://education.seattlepi.com/acid-rain-problem-today-100-years-ago-3926.html, Accessed 6/25/2014

An English scientist named Robert Angus Smith labeled the phenomenon of "acid rain" in 1872. During the late 19th century and the following decades, it was generally considered a limited and localized concern. By the 1970s, acid rain had become a widespread problem in the United States and other parts of the world. Over the last century, increasing amounts of sulfur dioxide and nitrogen oxides emitted from fossil fuel burning power plants, primarily from coal, have been identified as the main causes of increased acid rain. Increasing emissions of nitrogen oxides are a second major cause, as are volatile gas compounds released into the atmosphere from widespread use of agricultural fertilizers.




Acid Rain – Emissions UQ

Acid rain decreasing now—newest study proves continued emissions reductions key

So why don’t we hear so much about acid rain anymore?

There’s a hint of the answer in a study just out in the journal Environmental Science & Technology. Every summer for the past 23 years, the coauthors have been sampling 74 lakes across New England and New York state, and they report that acid rain is rapidly retreating. Concentrations of sulfate compounds in rain and snow declined by more than 40 percent from 2000 to 2010, while nitrate concentrations fell 50 percent. Levels of these pollutants in lakes fell correspondingly."This is really good news for New England,” coauthor William McDowell, at the University of New Hampshire, said in a statement. “Lakes are accelerating in their recovery from the past effects of acid rain. Our data clearly demonstrate that cleaning up air pollution continues to have the desired effect of improving water quality for our region's lakes."




Acid Rain – Takes out CO2 Ag




Coal plants are the leading causes of SO2, which destroys vegetation and pollutes the water and soil


Union of Concerned Scientists ’12, “Environmental impacts of coal power: air pollution,” Accessed 6/25/2014, http://www.ucsusa.org/clean_energy/coalvswind/c02c.html

Coal plants are the United States’ leading source of SO2 pollution, which takes a major toll on public health, including by contributing to the formation of small acidic particulates that can penetrate into human lungs and be absorbed by the bloodstream. SO2 also causes acid rain, which damages crops, forests, and soils, and acidifies lakes and streams. A typical uncontrolled coal plant emits 14,100 tons of SO2 per year. A typical coal plant with emissions controls, including flue gas desulfurization (smokestack scrubbers), emits 7,000 tons of SO2 per year.
