This has not a good year for coal in the United States. Fifty-five coal-burning power plants haveshut down this year alone including the Big Sandy power plant in Louisa, Kentucky
The significance of the Big Sandy plant is that it is
located right in the heart of coal country; near the Appalachian Mountains, an
area that has relied on coal, not only for energy, but as an economic driver
for decades.
EPA regulations have forced coal companies to decide whether to pay for expensive retrofitting
to their existing coal-burning electric power plants or to shut the burners down
permanently. The American Electric Power company has decided to shut down both
coal furnaces of Big Sandy, keeping open the possibility of retrofitting one at
a later date to burn natural gas.
For most environmentally-concerned individuals this would
seem like a major win. Burning coal not only emits a great deal of carbon
dioxide but also other harmful pollutants like particulate matter and sulfur
dioxide. Plus mining coal often involves significant environmental and
human costs.
The fact that a coal plant would shut down in an area where
coal is plentiful is an example of how social changes, concerns about global
warming and EPA regulations are changing the energy industry. But this begs the
question: what happens next?
Relying less on coal for energy means that burden going to
be placed on other sources of energy. At the present one of the main sources of
electrical energy is natural gas; while not renewable or devoid of emissions,
it is a much cleaner option than coal. But there are ramifications to
this shift to natural gas, making the environmental costs of
hydraulic fracturing (fracking) an even greater concern.
If natural gas becomes relied on for more electrical energy production,
natural gas companies have to find a safer way of removing it from the earth
for it to be a sustainable source of energy.
The options other than natural gas to coal are clean,
renewable sources of energy like wind. A decline in coal use presents a good
opportunity for renewable energy, but companies still need financial and
government support for these clean, renewable sources. And a much better
electrical distribution system infrastructure, particularly to move electricity generated from wind and solar to customers.
Although increased use of natural gas over coal may be an
encouraging trend and a step towards reducing our carbon emissions in the short
term, it is pertinent to keep in mind one of the significant costs of increased
use of natural gas - increased fracking - and the effects fracking will have on
the environment.
