The True Costs of Coal: New Study Adds Them Up

As the Bush administration touts their Energy Plan and pushes for increases in domestic energy production, conservationists across the Southern Appalachians are today calling their emphasis on coal into question for both economic and environmental reasons.

At the heart of the Bush Energy Plan is “clean coal technology,” an oxymoron to most conservationists but a linchpin in Bush’s plan to reduce our country’s reliance on foreign oil. At $30 per ton, electricity produced from coal is certainly a bargain at face value. But is that the true cost of burning coal?

That’s what two respected economists set out to find when they began a study of coal’s ledger sheet. Todd Cherry and Jason Shogren, both university-based environmental economists, found that the true cost of coal is about $150 per ton when all the social (human and environmental) costs are included.

Cherry and Shogren reached this conclusion based on studies of the impacts of the full coal cycle. The two economists say that if electric consumers look beyond the convenience of flipping on their light switches, they’ll find that “coal can also be dangerous and dirty.”

What of the impacts to humans and the environment from coal mining? What of the impacts of air pollutants from coal burning? Are these, in some cases severe, impacts taken into account in our monthly electric bill? In a word, no. Cherry and Shogren say consumers are paying only about 20% of the fuel cost for coal-generated electricity.

Coal Mining


The extraction of coal from the Appalachian mountains of West Virginia, Kentucky, Pennsylvania, Virginia and Tennessee is a time-honored tradition in the region. Indeed, coal literally fueled the industrial revolution of the 19th century when it became evident that hydropower was not sufficient to meet the burgeoning industrial demands of our nation. Cities such as Pittsburgh grew up in the coal fields because of the energy needs of the steel industry.

Small coal field communities sprang up in the late 19th and early 20th century throughout what we call “Appalachia.” Indeed, the term Appalachia and the practice of coal mining became synonymous.

Early coal mining was almost exclusively done in deep shafts that led to thick (5-10 feet) coal seams, which were blasted and picked out and loaded on rail cars to be drawn out of the mine by mules. Miners worked in dark, dusty conditions always at the risk of fatal roof falls and methane gas explosions. Beyond the risk of sudden death or serious injury, miners also faced the prospect of black-lung disease if they spent years in the profession.

Deep mining has indeed come a long way. Today, miners use a technique called long-wall mining, which involves a long (up to a mile) face of an underground coal seam which is dislodged by a saw that runs on tracks along the face. This method is much more efficient at removing thick coal seams than the old blast-and-pick method, and accounts for half to two-thirds of current Appalachian coal production. While some dangers are now less, current underground mining still results in fatal roof fall and explosion accidents.

Surface mining, or strip mining, has become more and more popular in recent decades, especially in removing thinner seams of coal (as little as a foot thick). The most recent innovation in strip mining is known as mountaintop removal. It peels back a mountain, layer by layer, by alternately blasting the thick layers of rock away from the coal seams and then scraping the coal seam out and hauling it away in huge dump trucks. Much of the “overburden” rock (the non-coal layers) is pushed off into adjacent valleys. As much as 500- to 1,000-vertical feet of a mountain may be removed in the process and valleys are filled in to depths of as much as 500 feet by the rubble.

Community effects of both underground and strip mining are myriad and devastating. What were once bustling communities in the coal fields are now ghost towns. This is partly because impacts that include blasting and coal hauling make community life all but impossible and partly because employment in the coal fields has shrunk nearly 90% over the last four decades.

“Between blasting (surface mining) and long wall mining impacts, lives are disrupted and emotional well-being is destroyed,” says Beverly Braverman, an activist with the Mountain Watershed Coalition near Pittsburgh, PA. “Things like cracks in foundations, loss of water in wells, having to move out of your house and still trying to get your kids on the bus every morning at the abandoned home site.”

“There’s a war being waged against the innocent men, women and children of Appalachia,” says Julia Bonds, of Rock Creek, West Virginia, a hotbed of mountaintop removal. “It’s a war directed by the greed of the coal industry and encouraged and accelerated by the Bush administration.”


In southern West Virginia, until recently the lead coal-producing state in the country (now second to Wyoming), coal mine employment in the 1950’s was about 120,000. Today, with more machine-intensive underground technologies and with modern mountaintop removal methods which rely on huge, $30 million machines called draglines, coal mining jobs are down to about 13,000, despite the fact that tons of coal produced has actually gone up. Thus, it’s the rare coal field community that doesn’t have many if not most of the previous businesses torn down, boarded-up, or teetering on bankruptcy.

Other major human impacts include highway accidents caused by overweight, out-of-control coal trucks. Truckers are paid by the ton of coal hauled to the rail head, and frequently are hauling twice the legal limit. “Coal truck drivers say that ‘reject’ coal (thin seam coal from mountaintop removal mines) is so contaminated with rock that they can’t haul it within the legal weight limits,” says Bonds.

Another major impact is that of increased flooding, which is at least partly if not mostly caused by various coal mining processes. When one coal sludge (the by-product of coal washing) dam broke in the 1970’s, 125 people in Logan County, West Virginia died. Today at least one sludge dam sits just above an elementary school near Sundial, West Virginia.

Losing Productivity


Many biologists believe coal mining represents the most severe destruction of natural ecosystems at this scale in North America. Underground mining causes acidification of streams as well as building-destroying subsidence on the human scale. Whole streams are rendered “dead” by acid mine drainage.

Mountaintop removal brings an abrupt end to the productive capacity of vast acreages of especially West Virginia, Kentucky, and Virginia. Hundreds of square miles of highly productive forests are rendered useless by the mining; as many as 1 million acres in the several states may have already been wiped out. Add to this the thousands of miles of streams that are buried alive under overburden across the region, and you get some impression of the scale of the environmental and economic cost of mountaintop removal.

What is the cost of these sizable impacts of coal mining? How do we put the cost of a life lost or a stream destroyed into dollars? How could we value the destruction of a community economy, or the productive capacity of forest lands forever lost? Some of these are not that hard to compute (lost forest growth per year per acre) while others (lost function of a stream) are harder to calculate in dollar figures.

According to Cherry and Shogren’s study, a human life lost is usually valued at about $6 million. Adding up deaths from coal mining, overweight coal truck accidents, and life lost from increased floods and sludge dam failures, they came up with a rough estimate. Loss of life probably represents a large percentage of any impact estimate.

But, in fact, nobody has pulled the data together on coal-related deaths, or of loss of productive land capacity, or of destruction of streams and community economics, to name only a few. “The need to do so is obvious, but perhaps we don’t want to know,” said Dr. Harvard Ayers, chairman of Appalachian Voices, a regional group fighting mountaintop removal.

Coal’s Deadly Impacts


Ever since coal was burned in England centuries ago to produce heat for homes, the combustion byproducts of it have been killing people, forests and water bodies. Only recently have scientists and economists teamed up to gain a broad understanding of the nature and amount of the resulting impacts to humans and the environment.

The main effect of coal burning is occurring as a result of electricity generation. According to Cherry and Shogren, coal accounts for just over half of all electricity generated in the United States. Most of the coal burning power plants are in the East. Western electricity fuel sources are much more heavily nuclear, natural gas and hydro.

Coal-burning air pollution harms human heath in several different ways. Tiny particles of sulfur and nitrogen from coal burners lodge deep in our lungs, causing as many as 30,000 premature deaths per year, according to the most up-to-date study by EPA consultant Abt Associates. Ozone derived from coal burning as well as from cars and trucks, causes or makes worse thousands of cases of asthma, and results in other heart and lung related maladies. Mercury from coal burning gets in the food chain mainly through fish and causes serious neurological and developmental problems for humans.

The forests, lakes and streams of the East are also seriously impacted by coal-derived air pollution. Acid precipitation (rain, snow, fog), ozone, and nitrogen (helpful as a fertilizer in small quantities but harmful in amounts emitted by coal-burning) all kill or at least reduce the growth of forests. Acid precipitation acidifies lakes and streams, rendering thousands of lakes, for instance in the Adirondack Mountains of New York, lifeless.


While trees are severely impacted by air pollution from coal at all elevations, mountain forests are the hardest hit. This damage has been clearly seen in the spruce and fir forests of the Blue Ridge and Smoky Mountains of the southern Appalachians. “To allow one of the world’s greatest centers of biodiversity to be destroyed by air pollution is at best irrational and is probably immoral,” says Dr. Robert Bruck of N.C. State University, who has studied the issue for 20 years.

Scientists and mappers hired by Appalachian Voices have further found that mountain hardwood forests with trees such as yellow birch, beech, and sugar maple are becoming sick and dying. The group has mapped tens of thousands of acres of such declining forests in the mountains of West Virginia, Pennsylvania, Virginia, Tennessee and North Carolina.

Finally, an important economic impact of coal burning is reduced visibility. Tourists who come to the mountains of areas like the Great Smoky Mountains National Park come largely to see the views. What they find in the summer season is haze.Views that should average 60 miles are cut, mainly by coal pollution, to about 15 miles, and to as little as 1 mile on some bad days every summer.

“Air pollutants emitted from sources across the U.S. are severely impacting streams, soils, public health, and visibility at Great Smoky Mountains National Park,” says Jim Renfro, Air Quality Specialist with the National Park Service. “To solve this problem, reductions of at least 80% of nitrogen and sulfur emissions are necessary to protect these resources.”

Whereas coal mining impacts have not been put into dollars to any extent, economists do have a growing body of studies of coal air pollution impact estimates. According to the Cherry/Shogren study, while the numbers for forest, stream/lake, crop and visibility damage are significant, the largest values come from human death and disease impacts. At $6 million per human life lost, we easily top $150 billion per year if we use the death figure (30,000/year) from the Abt Associates study.

Cherry and Shogren believe the $150/ton that coal should cost as compared to $30/ton that it now costs, is conservative.

The Coal Summit


On June 20-22 of 2002, several local, regional and national environmental and community groups are presenting the Coal Summit in Charleston, West Virginia. The purpose of the Coal Summit is to offer environmentalists, politicians, the media and the general public an accurate, first-hand picture of the true cost of the full coal cycle. Experts will speak to the myriad impacts and the public will be encouraged to join in discussions of these issues. Field trips by air and by ground will offer a first-hand view of the devastation by coal mining and also of the forest damage of coal-derived air pollution. People interested in attending the Coal Summit should contact Melissa Davis at 828-262-1500 or toll-free at 1-800-277-8642. Information about the Coal Summit is also available at www.appvoices.org.
