Executive Summary
Energy
companies have proposed building a fleet of new coal-fired power plants
across America. As of June 2006, power producers have approximately 150
new coal-fired plants on the drawing board, representing a $137 billion
investment and the capacity to supply power to 96 million homes.
In Oregon, the Summit Power Group has proposed a coal plant on the
lower Columbia River and PacifiCorp has proposed building 3 coal plants
in Utah and Wyoming to serve Oregon customers.
If
energy companies succeed in building even a fraction of these new power
plants, it would have major impacts on America’s environment and
economy. Further, this “coal rush” would consume investment dollars
that could otherwise promote more sustainable energy sources.
Fortunately, alternatives exist that would reduce or eliminate the need
for new coalfired power plants. By funneling investment instead into
improvements in energy efficiency and expansion of renewable energy,
the U.S. can avoid the potential impacts of the “coal rush” and improve
the economy, the environment and public health.
The “coal rush” would increase U.S. global warming pollution at a time when aggressive action is needed to reduce emissions.
•
To avoid the worst consequences of global warming, scientists believe
that the U.S. needs to stabilize emissions within a decade, begin
reducing them soon thereafter, and cut global warming pollution by as
much as 80 percent by the middle of this century. New coal-fired power
plants will take us in the wrong direction.
•
If all of the proposed plants are built, they would increase U.S.
carbon dioxide pollution from electricity generation by more than 25
percent above 2004 levels. This would be equivalent to a 10 percent
increase in total U.S. emissions and a 2.4 percent increase in world
emissions.
•
The new coal plants proposed for Oregon would increase in-state global
warming pollution from electricity generation by 38 percent and total
Oregon emissions (including out-of-state emissions for Oregon
electricity) by 9 percent.
•
The vast majority of proposed plants, including PacifiCorp’s planned
coal plants, use traditional coal-burning technology, which emits
massive amounts of carbon dioxide. Only 16 percent of the proposed
plants, including the one planned for Oregon, would use coal
gasification technology and could someday be equipped to capture and
store carbon dioxide. Even these plants would require costly future
upgrades to avoid large releases of global warming pollutants.
Increasing
America’s dependence on coal carries significant economic risks for
power generating companies, their shareholders, utility ratepayers, and
the economy as a whole.
•
The growing urgency of addressing global warming makes limits on carbon
dioxide pollution a virtual certainty for the future. As these limits
are set, coal-fired power plants will decline in value compared to
lesspolluting resources. Additionally, companies or ratepayers may be
forced to pay the significant cost of retrofitting the new plants to
capture and store carbon dioxide.
•
Companies that build coal-fired power plants today knowingly and
significantly contribute to the public health, environmental and
property damage that will result from global warming. Such companies
face potential legal risks, similar to the lawsuits filed against the
tobacco industry in the last decade.
•
The new coal-fired power plants, if built, will strain the U.S.’s
ability to extract and deliver enough coal to keep them running. U.S.
coal demand would increase by over 30 percent if all the plants are
built, requiring additional mines and expanded railroad infrastructure
to move the coal around the country. Mining additional coal would
damage America’s land and water.
•
According to the U.S. Department of Energy, currently operational coal
mines have enough recoverable coal to supply the power industry for
only 18 years at current levels of demand (and fewer years if demand
increases).
•
While the U.S. has enough coal supplies to sustain current levels of
consumption for nearly 200 years, extraction of that coal is likely to
damage wide areas of land now used for agriculture, housing and
recreation, while fouling water supplies and harming wildlife.
•
Between 1985 and 2001, “mountaintop removal” coal mining in Appalachia
cut down more than 7 percent of the region’s forests and buried more
than 1,200 miles of streams.
•
In 2004, coal mines across the U.S. reported the release of more than
13 million pounds of toxic chemicals, including over 300,000 pounds
dumped directly into streams and rivers. The “coal rush” would increase
health-threatening air pollution.
If
all of the planned coal-fired power plants are built, they would
increase total pollution from power plants and other industrial
facilities on the order of 1 to 3 percent, including:
•
120,000 tons per year of sulfur dioxide, a major ingredient in fine
particle pollution, linked to premature death and respiratory and
cardiovascular disease;
•
240,000 tons per year of nitrogen dioxide, a major ingredient in the
photochemical smog that plagues many cities across the U.S. on summer
days; and
• 3 tons per year of mercury, a neurological toxicant that contaminates fish in rivers, lakes and the oceans.
The “coal rush” would consume investment dollars that could be used to
promote safe and sustainable energy sources, including energy
efficiency and renewable energy.
•
Building all of the coal-fired power plants on the drawing board would
require capital investment of $137 billion. On top of that, energy
companies would have to spend more than $100 billion to operate,
maintain and fuel the plants and build transmission lines.
•
If that $137 billion in capital were 6 Making Sense of the “Coal Rush”
instead directed toward energy efficiency, it could reduce electricity
demand in 2025 by about 19 percent compared to a business-as-usual
forecast (1 million GWh/year), without additional investment for
transmission and distribution. In other words, energy efficiency could
completely alleviate the need to build any new coal-fired power
plants—and do so for less cost and with zero global warming pollution.
•
Directed instead toward renewable energy, that $137 billion could
develop 110 GW of the best wind resources in the western U.S. with a
cost of electricity comparable to conventional coal. Alternatively, the
money could build over 50 GW of promising zeroemission solar
technologies like concentrating solar thermal power plants—predicted to
provide electricity at prices competitive with coal within the next 10
years, with the potential to supply energy day or night using thermal
storage.
•
Wind, solar, tidal, geothermal and biomass resources—coupled with
energy-saving renewable technologies such as passive solar heating and
lighting, solar hot water heating and geothermal heat pumps—could
provide a large and growing share of America’s energy. A consistent
emphasis on renewables in public policy and in research and development
funding could bring many of these technologies into the mainstream—but
not if America’s investment dollars are staked on coal.
Citizens and government should act to stop the “coal rush” and instead
pursue a cleaner, more sustainable path to satisfying America’s energy
needs.• Oregon and the U.S. as a whole should impose strong caps on
global warming pollution from power plants at levels that are
sufficient to minimize human interference with the global climate—on
the order of 80 percent below 1990 levels by mid-century.
Oregon and the federal government should not allow any new coal facility to be built, unless:
•
All the costs of coal-fired power plants—including the societal cost of
global warming and the probable cost of additional pollution control
requirements—are fully considered when utility investment decisions are
made;
•
Gasified coal with carbon storage is demonstrated to be the least-cost
way to reduce global warming pollution consistent with climate
stabilization goals, compared to other clean resources that could
satisfy or reduce energy demand, such as renewable energy and energy
efficiency; and
•
Any new gasified coal plants with carbon storage are used to replace
old, inefficient coal-fired power plants, not augment them.
• Public funds should not be used to support the construction of any coal-fired power plants.
•
Leaders at all levels of government should take aggressive action to
encourage the development of cleaner alternatives to coal-fired power
plants, particularly measures to improve energy efficiency and
encourage the development of clean renewable resources.
•
Oregon should require that 25% of its electricity come from renewable
resources by 2025. In addition, Oregon should increase the public
purposes charge program, which funds energy efficiency and renewable
energy investments administered by the Energy Trust of Oregon.
