As I understand it, clean coal really isntyet
the Bush Administration gushed strongly for it. What is Obamas
take on it? -- John Zippert, Eutaw, AL
Barack
Obama and George W. Bush differ in many ways, but both have
embraced so-called clean coal for providing an
ongoing supply of cheap and readily available energy for electricity
generation.
The term clean coal is loosely defined as coal
that is washed or processed to remove pollutants, so as to
reduce emissions of carbon dioxide (CO2), the leading greenhouse
gas, when the coal is burned. Coal-burning plants emit 40
percent of US CO2 pollution-half of our electricity comes
from coalso reducing the industrys carbon footprint
in any way possible would be a big win for the environment.
Luckily for clean coal advocates, the White House has been
and continues to push for its development. George W. Bushs
support for clean coal dates back to his first term in office,
when he stated that such technologies should be encouraged
as a means of reducing dependence on foreign oil. And since
taking office, the Obama administration has committed $3.4
billion in stimulus dollars to clean coal projects.
But green groups continue to question the wisdom of relying
on coal at all. Coal wreaks environmental havoc, from the
coal mines that pollute rivers and streams, to the premature
deaths of coal miners from accidents and lung diseases, to
the release of greenhouse gases, mercury and other toxins
at power plants.
According to Greenpeace, burning coal emits 29 percent more
CO2 than does burning oil or natural gas. And coal-fired power
plants are the worlds largest sources of atmospheric
mercury, a known neurotoxin that disperses quickly throughout
the environment and into the food chain. Greenpeace says that
clean coal technologies will not address this problem, and
that there are no commercially available technologies
to prevent mercury emissions from coal-fired power plants.
Also, the group says, clean coal will do nothing to mitigate
coal minings damage to wildlife habitat and drinking water
sources.
There is no such thing as clean coal and
there never will be, Dan Becker of the Sierra Club told
the Grist.org website. Its an oxymoron.
The Reality Coalition, a group of nonprofits that includes
the Sierra Club, has been running TV ads seeking to debunk
industry claims that coal can be clean. Green groups also
worry that pushing clean coal will only delay the transition
to a truly cleaner and greener energy infrastructure based
on solar, wind and other emissions-free renewable energy sources.
In April of 2009, environmental lawyer Robert F. Kennedy,
Jr. questioned the motivations of Obama and other politicians
who back clean coal. The coal industry and the carbon
industry in general are the largest contributors to the political
process, Kennedy told ABC News. You dont
have politicians representing the American public, but rather
the people who finance their campaigns.
Of course, Obamas support for clean coal doesnt negate
the fact that he has proposed spending much more on further
development of alternative energy sources. He has called for
getting 10 percent of U.S. electricity from renewable sources
by 2012 and 25 percent by 2025, and has committed upwards
of $32 billion of stimulus dollars to the cause, according
to an analysis by the nonprofit Environment America.
