COAL According
to EPA, American coal plants produce 386,000 tons of
hazardous air pollutants per year. The toxins they release, hazardous chemicals
that can lead to disease, brain damage and premature death, affect every part
of the human body. Arsenic, chromium and nickel cause cancer; lead damages the
nervous system; acid gases irritate the nose and throat; dioxins affect the
reproductive endocrine and immune systems; and volatile organic compounds
weaken lungs and eyes. link The global dominance of industrial interests dependant on cheap
energy sourced from coal means that climate change is inevitable.
Unfortunately, there is enough cheap coal around to power ever-higher
emissions for at least another century. The world will thus become much
warmer. link Other extremely
serious side-effects include coal ash
storage and mountaintop removal.

Jan. 27 2012: Coal does more harm than good in Kentucky.
Kentucky, the third-largest coal producer in
the U.S., generates about 94% of its electricity from the resource and
has some of the lowest electricity prices in the country. But
according to a health impact study by the Kentucky Environmental
Foundation that examines research on the impact of coal in Kentucky, the health
costs came in at more than $62 million in 2007, and that’s just for asthma,
which inflicts 1 in 10 Kentuckians and kills about 50 people in the state per
year. Asthma rates for African Americans of high school age in Kentucky are at
22%. The report examines costs along
the coal value chain, including mining, transportation and electricity
generation. KEF cites a study from Public Health Reports that finds 2,347 to
2,889 yearly excess deaths from coal mining in Appalachia, costing the region
an estimated $10 billion each year. link

March 2011: The Union of
Concerned Scientists have issued a report titled, “A Risky Proposition” which concludes that in the 1970s there was a massive over-investment in
coal and nuclear plants without proper heed to the associated financial risks.
This blind over-investment led to cancellation of 100 nuclear plants and 80
coal plants. But the money was already spent: hundreds of millions or even
billions of dollars were wasted and electricity prices skyrocketed, municipal
bonds defaulted and legal battles arose. Many people continue
to think that coal is the cheapest and most plentiful electric fuel. “A Risky
Proposition” expertly debunks these lingering misconceptions. link __________________________________________________________

Coal is so
abundant that it
is the obvious fuel of choice, yet it is also a
growing contributor of CO2
pollution. Coal plants generate almost half of the electricity in the USA and 80% of
the nearly 2 billion tons of carbon dioxide released annually into the
atmosphere comes from power production.
West Virginia sits on more than 30 billion tons of coal and produced
158 million tons in 2008, second only to Wyoming at 468 million.
Producing it causes devastating results to the landscape,
especially
in the Appalachians where mountains are removed 24 hours every day.
Environmentally, coal is unacceptable, therefore much effort is being
put into
clean coal technology (liquid coal and gasified coal) and carbon
sequestration. These methods are
prohibitively
expensive and presently non-viable. In selecting coal over alternatives
it's
also important to factor in taxpayer subsidies as well as serious
health
consequences. Nationwide, more than 90 coal plants have been cancelled or put on hold in the
past three years, due to projected greenhouse gas emissions, mushrooming costs
and public opposition.
Coal's decline in USA. In
2010, 44.9% of power generation was coal-based, according to the Edison
Electric Institute. Natural gas had 23.8% of the market share, nuclear 19.6% and
the rest was made up of hydro, renewables and other methods of power generation. Between 2010 to 2022,
48 gigawatts of coal will have been retired at 231 plants: that’s 14.1% of the
total 339,000 megawatts of coal-fired power generation in 2010. All except 6
plants are more than 30 years old; the majority of plants are older than 50
years.

| Reliance on coal and its future |
October 2011: Coal
is doing more harm to the US economy than good. A new economic analysis has made a damming
assessment of the costs of pollution from fossil fuel industries, and concludes
that coal is doing more harm to the US economy than good – and that doesn't
take into account its climate impact. The most damning assessment is of coal,
which is fingered for about $53 billion in damages a year. This estimate
does not include climate change and uses a conservative estimate of health
risks.. The paper, published in the highly prestigious American Economic Review, by respected economists Nicholas Muller, Robert
Mendelsohn (Yale) and William Nordhaus (Yale), models the physical and economic
consequences of emissions of six major pollutants (sulfur dioxide, nitrogen
oxides, volatile organic compounds, ammonia, fine particulate matter, and
coarse particulate matter) from the country's 10,000 pollution sources. It is
an update of a previous study concluded in 2009. link January 2011: Banks, climate & the Carbon Principles. In February 2008, three leading banks, Citi, JPMorgan
Chase and Morgan Stanley, announced
common coal power financing policies, known
as the Carbon Principles. Heralded as a new path for the banking
industry, the Carbon Principles were supposed to make it “tougher to finance
conventional coal-fired plants in the U.S.” Today Rainforest Action Network examines
the implementation and impact of these Principles, and the role that banks play
in financing new coal plants – and the news is not good. Our research reveals
that, while the broader economy has been shifting away from new coal power
plants, the banks that have signed onto the Carbon Principles are continuing
with business as usual in regards to financing coal. Burning coal is the
nation's top source of air pollution and toxic mercury, and it is responsible
for one third of the country's greenhouse gas emission, nearly 2 billion tons
per year. link (Click here to see report) September 2010: Europe weaning itself off coal - ending subsidies. The
European Commission in May announced that bailouts and favors,
subsidies, for mining and coal plants would end after 2010. Though the
European Union generally prohibits national subsidies, coal has long
been an exception.The goal is not to eliminate coal power but to
replace it, where it is not economical, with cleaner forms of power. link August 2010: Old style coal plants expanding across US. Records
show that more than 30 traditional coal plants (i.e. without carbon
capture) have been built since 2008 or are under construction. Much
lower than the previous 151 a few years ago, but still enough to
provide 17,900MW of energy which would emit 25 million tons of
greenhouse gases annually. It suggests the industry believes carbon
regulation may not be a serious threat. Construction costs are,
however, on the rise and could deliver increases in energy bills up to
30%. link January 2010: In 2009, plans for 26 new coal-fired power plants were
shelved nationwide according to the Sierra Club. A few utilities also
considered closing operational coal plants, but most are "very old coal
plants" that do not operate frequently. Also Oregon's only coal-fired
plant is being closed early because of costs and environmental
reasons. link February 2010: Coal-fired power on the way out? Analysis by Lester R. Brown, Earth Policy Institute. The
past two years have witnessed the emergence of a powerful movement
opposing the construction of new coal-fired power plants in the United
States. Initially led by environmental groups, both national and local,
it has since been joined by prominent national political leaders and
many state governors. The principal reason for opposing coal plants is
that they are changing the earth’s climate. There is also the effect of
mercury emissions on health and the 23,600 U.S. deaths each year from
power plant air pollution. Coal’s future is also suffering as Wall
Street turns its back on the industry. more
| Cost of coal, including health |
There are unseen problems with coal we know little or nothing about. According to ORNL (Oak Ridge National Laboratory) Americans living near coal-fired power plants are exposed to
higher radiation doses than those living near nuclear power plants that meet
government regulations. link Also, with South Carolina as one example, 2.3 billion pounds of ash are dumped there annually in landfills and ponds and at some of these ponds, arsenic and other heavy metals in the ash leached into
groundwater. link Revealing is the TVA disclosure that in just one year, the plant’s byproducts included 45,000 pounds of arsenic, 49,000 pounds of lead,
1.4 million pounds of barium, 91,000 pounds of chromium and 140,000 pounds of manganese. Those metals can
cause cancer, liver damage and neurological complications. more According to the American Lung Association, pollution from coal-fired power
plants causes 23,600 premature deaths, 21,850 hospital admissions, 554,000
asthma attacks, and 38,200 heart attacks every year. The Center for Disease
Control (CDC) estimates that 12,000 coal miners died from black lung disease
between 1992 and 2002. July 2011: E.P.A. sets new standards for coal-burning plants. New
standards have been issued for coal-burning power plants in 28 states that
would sharply cut smokestack emissions that have polluted forests, farms, lakes
and streams across the eastern United States for decades. The new regulations
will take
effect beginning in 2012, and would cut emissions of soot, smog and acid rain
from hundreds of power plants by millions of tons at a cost to utilities of
less than $1 billion a year. The E.P.A. said the cleaner air would prevent as
many as 34,000 premature deaths, 15,000 nonfatal heart attacks and hundreds of
thousands of cases of asthma and other respiratory ailments every year. link
Mercury is a serious by-product of burning coal.
Coal-fired power plants are the source for two-thirds of
mercury air emissions in the United States. Latest figures suggest U.S. coal plants
release 29 tons of into the air each year. To read more on mercury link to the Cliffside page.
Cost to our health
February 2011: Health costs of coal - $345 billion a year.. A
Harvard University researcher found the United States' reliance on coal to
generate electricity, costs the economy about $345 billion a year in hidden
expenses not borne by miners or utilities, including health problems in mining
communities and pollution around power plants, a study found. Those costs would
effectively triple the price of electricity produced by coal-fired plants,
which are prevalent in part due to their low cost of operation.The study said the costs could be as low as $175 billion or as high as $523 billion. link
November 2009: "Coal's
Assault on Human Health." Coal is an epidemic and exposure to emissions from coal combustion is killing 40,000 to 50,000 Americans
per year reports the Physicians for Social Responsibility. Coal
pollutants affect all major body organ systems and contribute to four
of the five leading causes of mortality in the U.S. - heart
disease, cancer, stroke, and chronic lower respiratory diseases,
concludes the scathing report issued today. "Each step of the coal lifecycle - mining,
transportation, washing, combustion, and disposing of postcombustion
wastes - impacts human health," warns the report. In addition, the report states, "the
discharge of carbon dioxide into the atmosphere associated with burning
coal is a major contributor to global warming and its adverse effects
on health worldwide." link
October 2009: Burning fossil fuels costs the U.S. about $120 bn a year in health
costs
according to the National Academy of Sciences, mostly because of
thousands of premature deaths from air pollution. The damages are
caused almost equally by coal and oil, according to the study
which was ordered by Congress. The study set out to measure the costs
not incorporated into the price of a kilowatt-hour or a gallon of
gasoline or diesel fuel. link |
May 2010: UCS - Three dozen states are collectively hemorrhaging tens of
billions of dollars annually on imported coal to generate electricity, according
to a report released by the Union of Concerned Scientists (UCS). Residents in those states would be better served, the report concludes, if
more money were spent in-state on local renewable energy technology and energy
efficiency programs. The first-of-its-kind report, which ranks the 38 states that are net
importers of domestic and foreign coal based on the most recent available data,
found that 11 of them each spent more than $1 billion annually on imported coal
in 2008. 63% of domestic coal comes from just three states: Wyoming, West
Virginia and Kentucky. Foreign coal burned in U.S. coal plants mainly comes from
Colombia. "Importing coal to produce electricity is a drain on state economies," said
Jeff Deyette, the assistant director of energy research and analysis in UCS's
Climate & Energy Program and a report co-author. "Ratepayer dollars are
diverted out of state instead of spent locally on renewable energy projects and
energy efficiency measures that would benefit residents directly." (More than 80% of the foreign coal imports in 2008 came from Colombia. The
balance came from Venezuela and Indonesia and the United States still exports more coal than it imports.) link
November 2009: Tennessee authorizing new discharges of toxic heavy metals - one million
gallons a day - into the same river devastated by the Kingston coal ash spill. - there are no federal laws prohibiting this pollution. "Coal-fired
power plants around the country are installing scrubbers without proper
controls to limit water pollution because the U.S. Environmental
Protection Agency has failed to set national standards governing
wastewater discharges from scrubber systems," environment groups said
in a joint statement. This is simply transferring the toxic emissions
from the air to the water supply. link (see more below under "Scrubbers)
Is there
such a thing as "Clean Coal"? A new coalition under the
umbrella - 'this is reality' argues there is not link Scrubbers clean coal - but move pollutants from air to the water instead. June 2008: 'Scrubbers' provide a method of
removing up to a tonne of CO2 each day from the air - roughly the
equivalent
amount produced by a transatlantic flight. Each device would cost around
£100,000. (February 2009 conversion = $ 145,000) Scientists have stressed their invention does not provide a
magic
solution to the problem of CO2 emissions. Millions of the devices would
need to
be produced to capture all global emissions, and the problem of
disposing of
the CO2 once it has been trapped still remains. Scientists have
previously been
skeptical about the feasibility of air-capture devices, due to the
large
amounts of energy required to run them. Link
October 2009:
In 2006 Allegheny Energy in Pennsylvania decided to install scrubbers
to clean the plant’s air emissions, environmentalists were overjoyed.
The technology would spray water and chemicals through the plant’s
chimneys, trapping more than 150,000 tons of pollutants each year
before they escaped into the sky. But the cleaner air has come at
a cost. Each day since the equipment was switched on in June 2009, the
company has dumped tens of thousands of gallons of wastewater
containing chemicals from the scrubbing process into the Monongahela
River, which provides drinking water to 350,000 people and flows into
Pittsburgh, 40 miles to the north. link July 11 2011: Scrubbers are key weapons in the fight to reduce pollution at
coal-fired power plants. However their life-span of 25 years is suspect. The
Electric Power Research Institute, which is funded by utility companies, is
investigating reports of "aggressive" corrosion in scrubbers across
the nation. "Our findings, so far, show it's fairly widespread through the
industry," said John Shingledecker, senior project manager in the research
institute's fossil materials and repair program. Without a fix, corrosion
threatens plant shutdowns and costly repairs, both of which could affect power
bills. They were installed to help meet a federal mandate that coal-fired power
plants cut 71% of their sulfur-dioxide emissions by 2014. link Every hour of every day the USA burns over 100,000 tons of coal. Each
pound of coal
produces 3.7 pounds of CO2 (if treating coal as pure carbon, which it
is not.
Bituminous coal generally has lower concentrations of pure carbon -
between 46%
to 86%) The US currently uses 1.05 billion tons a year. Coal provides 26% of global primary energy needs and generates 41% of
the world's electricity. For latest global statistics on producers and exporters etc. link here Coal consumption by country - link |
To read more on Carbon Capture and Storage - link For
an exhaustive study of "How to Clean Coal" refer to
the Natural Resources Defense Council's essay:
link According to
the NRDC
(Natural Resources Defense Council) relying on coal-derived liquid as
an
alternative to oil-based fuels could nearly double global warming
pollution for
every gallon of transportation fuel that is produced and used. The
total
emissions rate for oil and gas fuels is about 27 pounds of carbon
dioxide per
gallon, counting both production and use, while the estimated total
emissions
from coal-derived fuel is more like 50 pounds of carbon dioxide per
gallon. link
Liquefied coal – CTL – an alternative
to oil? The liquefaction of coal is one concept that is being given new life
due to higher petroleum prices. Currently it is cost-prohibitive and
environmentally unfriendly. But according to a new study from the MIT, as early
as 2015 and without a solid climate policy, coal-to-liquid (CTL) fuel may be
economically viable in the US and China. CTL fuels have been
in existence since the 1920s, and were used extensively by Germany in the
1940s. At the time, it produced about 90% of their national fuel needs. Then
Middle Eastern oil became dirt cheap and CTL technology was largely abandoned.
The only country that still uses it in a significant way is South Africa where
it covers about 30% of their fuel needs. The
production of liquefied coal has a large carbon footprint, much larger than
that of petroleum fuel production. One method of production is carbonization
where the coal is coked at temperatures up to 1,380 F to produce coal tars rich
in hydrocarbons. The coal tar is then further refined into fuels. The process
produces a large amount of carbon dioxide emissions. If done without CCS
technology, the life-cycle carbon footprint is about double that of crude oil. The
study notes that the viability of CTL will by vary greatly on whether or not certain
regions adopt prohibitive climate policies. If lower-carbon fuels are
available, CTL would not be considered as an option. Liquefied coal may only be
available in developing nations with lax environmental rules, and where
low-carbon alternatives are not available. One of the study's authors, John
Reilly, stated, "Various climate proposals have very different impacts on
the allowances of regional CO2 emissions, which in turn have quite distinct
implications on the prospects for CTL conversion. If climate policies are
enforced, world demand for petroleum products would decrease, the price of
crude oil would fall, and coal-to-liquid fuels would be much less
competitive." link
December 2009:
Major spill in Tennessee.
Initial reports that 1.7 million cubic yards of wet coal ash had
spilled when the earthen retaining wall at the Kingston Fossil Plant in
Tennessee gave way was revised to 5.4 million cubic yards, more than
the TVA (Tennessee Valley Authority) said was in the pond.
Environmentalists have long argued that coal ash, which can contaminate
ground water and poison aquatic environments, should be stored in lined
landfills. link December 2011: Coal ash still a huge problem, three years after spill. link For decades, the dangers of coal ash have largely been hidden from public
view. Today, there are 194 landfills and 161
ponds containing coal ash from 500 power plants in 47 states
nationwide according to 2005 data from the
Department of Energy, the latest available. Each year power companies generate approximately 130 million tons of coal ash -
enough to fill a million railroad cars. Industry representatives estimate 43
percent of coal ash now gets recycled in such items as concrete or wallboard -
two "beneficial uses" that use one type of coal ash. But that still leaves more
than 70 million tons of ash annually for companies to dump in lagoons,
landfills, and, more recently, mine pits. The ash amounts to dirty stuff, replete with toxic constituents -
arsenic, chromium, lead, mercury, and many others - that can wreak havoc on the
environment and human health. Exposure to its toxins can lead to cancer, birth
defects, gastro-intestinal illnesses, and reproductive problems. There is no meaningful federal regulation of coal ash on the books; indeed,
oversight of ash disposal - much of it stunningly casual - is largely left to
the states. more March 2011: The EPA must act on coal ash within 90 days. Internal EPA research shows
the agency promoted the use of coal ash products, on farm fields, as structural
fill for roadway embankments or bound into products such as wallboard,
concrete, roofing materials and bricks, with incomplete information about
potential risks to people's health and the environment, and has given the EPA
90 days to respond. The not-so-gentle reminder stems from a policy put in place
during George W. Bush's presidency. The amount of
coal ash generated by the nation's coal-fired electricity plants has grown from
118 million tons in 2001 to 136 million tons in 2008, according to the EPA's
latest figures. Ash contains a range of dangerous metals such as arsenic,
selenium, cadmium, lead, and mercury that can leach into groundwater and
migrate to drinking water sources. link June 2009: The
EPA disclose the location of 44 coal ash disposal sites
across the country that are classed as "high hazard." North Carolina has the most - twelve - sited at Belmont, Walnut Cove, Spencer, Eden, Mount Holy, Terrell and Arden. Two electric utilities - Columbus, Ohio-based America Electric Power and
Charlotte-based Duke Energy Corp. operate nearly half of the coal ash sites on the list. link | Elsewhere around the world |
China
now uses more coal than the United States, Europe and Japan
combined. China’s
frenetic construction of coal-fired of power plants has raised
worries around the world about the effect on climate change. making it the world’s largest emitter of gases that are
warming the planet. But largely missing in the hand-wringing is this: China has emerged in the
past two years as the world’s leading builder of more efficient, less polluting
coal power plants, mastering the technology and driving down the cost. After relying until recently on older technology, “China has since become the
major world market for advanced coal-fired power plants with high-specification
emission control systems,” the International Energy Agency said in a report a on April 20 2009. link March 2010: UK plan to burn coal underground and cut out mining. Coal gasification is an old idea. What is new is cutting out the coal
mining stage and doing the gasification underground. Instead of mining coal the idea is to burn entire coal seams
in situ underground, then tap the gases that the fires give off to put in gas
turbines and generate electricity. In
principle it is simple. You sink a borehole to the coal seam and insert
a firelighter and oxygen to keep the fire going. The fire generates
carbon dioxide, methane and hydrogen. You sink another borehole to
extract the gases. The problem is that methane is not the only gas
to emerge from underground. While the engineering trick is to
manage the fires to maximise methane production, there will inevitably
be a lot of CO2 produced by the fires as well. So is this clean coal or greenwash? link See also the Cliffside page for a closer look at how one proposed plant in NC is under threat.
COAL GASIFICATION Gasification is very energy-intensive, requiring high-temperature air, steam or
oxygen to react with the organic material. Gasification breaks down coal into its basic
chemical
constituents using high temperature and pressure which leads to the release
of large amounts of carbon dioxide. In addition, gasification is often
inefficient, leaving behind significant amounts of solid waste. In theory coal
gasification offers a versatile and clean way to convert coal into electricity. Because of this,
carbon
dioxide can be captured from a gas stream far more easily than from the
smokestacks of a conventional coal plant. One significant challenge is
the
historically short lifespan of refractories, which are used to line and
protect
the inside of a gasifier. Currently, refractories have a lifespan of 12
to 16
months. The relining of a gasifier costs approximately $1 million and
requires
three to six weeks of downtime.
link
A clean burning
plant would cost 20% more than a
conventional coal-fired facility with the same capacity and almost four
times
as much as a similar-size generator fueled by natural gas.
Environmentalists
see the advantage that instead of emitting CO2 into the atmosphere,
where it
traps heat, the new design could one day extract the gas from the
chemical
reactor and then "sequester" it deep underground. link
If gasified
coal plants are a solution, we need to
calculate the costs of sequestration and contrast all costs with solar,
wind
and wave advances as well as continuing environmental damage.
However in Nevada,
construction of Sierra Pacific Power's Pinon Pine project which
began in early 1995 was plagued by cost overruns. In late
1996 a
conventional, gas-fired power plant came on line: the experimental
gasified coal system was shut down. Total costs for the entire plant
ran more
than $340 million. The Nevada utility got more than $200 million in
taxpayer
and ratepayer dollars for the experimental clean-coal generating plant
that
wouldn't run reliably. link
| Coal industry lobbying and subsidies |
US
Subsidies to energy: According to The National
Academy of Sciences the federal
government invested $644 billion (in 2003 dollars) between 1950 and
2003 in
efforts to promote and support energy development. Of this,
only $60.6
billion or 18.7% went for R&D. It was dwarfed by tax incentives
(43.7%) Also tax
incentives comprised 87% of subsidies for natural gas. Federal market
activities made up 75% of the subsidies for hydroelectric power. Tax
incentives
and R&D support each provided about one-third of the subsidies
for coal.
September 2009:
During the fiscal years 2002-2008 the United States handed out
subsidies to fossil fuel industries to a tune of $72 billion. Of that,
$2.3 billion went to carbon capture and storage; the rest went to oil
and coal. link Germany:
After spending more
than $200 billion in subsidies since the 1960s, the federal
government decided in 2008 that they would be phased out by 2018 being too
unaffordable.
Economists and free-market lawmakers have long decried the subsidies as
handouts to the politically influential coal industry and powerful
trade
unions. This year, for instance, Deutsche Steinkohle AG, the owner of
the remaining
eight mines, will receive more in government subsidies ($3.3 billion)
than it
will from selling coal ($2.9 billion).
$427
million. That's what the oil and coal industries spent during
the first
half of 2008 on lobbying and advertising. According to USA Today (April
27, 2009) "Fifty of the
nation's largest electric utilities amped up spending on lobbyists by 30% late
last year to influence the debate in Congress just underway on one of the
biggest issues facing lawmakers: climate change." Industry opposes clean energy. The Guardian recently ran an investigative piece finding that America's oil, gas and coal industry "has
increased its lobbying budget by 50%, with key players spending $44.5m in the
first three months of this year (2009) in an intense effort to cut off support for
Barack Obama's plan to build a clean energy economy." link
