The topic of alternative energy has received more attention in the media lately,
due to a combination of major political issues. President Bush has been taken
to task about his intentions concerning the “energy crisis” and his environmental
policies. The fact that both President Bush and Vice-President Cheney are oil
men certainly does not help the prospect of alternative energy getting much
attention during their administration. So the outlook seems bleak for citizens
concerned about conservation of the world’s natural resources, and for alternative
energy becoming commonplace in America’s homes and industry.
Before delving into the latest innovations in alternative energy, the critical
need for these alternatives should be addressed, especially with President Bush
threatening to diminish environmental efforts of the last eight years. For instance,
Energy Secretary Spencer Abraham declared the energy crisis could only be resolved
by repealing the environmental and regulatory obstacles to increasing coal and
oil supplies, and the Bush administration stated the 45% growth in demand for
electricity warrants building 65 to 90 power plants a year. On the local level,
the transmission line controversy represents exactly what could happen in communities
similar to Rabun County, all around the country. President Bush also reneged
on his campaign pledge to curb carbon dioxide emissions, which is critical for
reducing pollution from coal and oil burning plants. And there’s the well-publicized
debate about the need to drill in the Artic National Wildlife Refuge. Our growing
dependence on natural gas will threaten many other federally protected lands
currently closed to exploration.
Whether or not there is a legitimate “energy crisis,” surely there is a need
for changing our dependence on the 19th century fossil fuel burning technologies
that President Bush is intent on expanding. The fact does remain that there
is population growth and a greater demand for non-renewable resources. Is there
a perfect solution for energy issues? A perfect solution would not produce harmful
emissions, dam rivers, ruin farmland, strip mine, and decimate thousands of
acres of land. The solution should also provide jobs and contribute to local
tax structures while fueling the national and global economies. The answer may
be in the form of combining many options that could suit the particular city,
community or individual’s needs, specific to the geography and natural resources
of the area.
Many major power companies are searching for the answers, and have spent millions
of dollars researching and implementing alternative methods of power generation
and storage. Power companies in the West, especially along the Mexican border,
have been buying power from smaller geothermal plants. According to a March
22, 2001 article in the New York Times, there are 10 geothermal plants located
near the Salton Sea that extract superheated water to create energy, and pay
taxes high enough to greatly impact the local economy. Yet an unfortunate domino
effect from California’s failing power companies is a loss in revenue for the
geothermal companies reliant upon selling their power surplus. Some geothermal
companies are being forced to cease generating power until they receive payment.
Still, examples remain of communities making use of their best local and alternative
resources. Geothermal energy is more suited to the Southwest; however, we have
options unique to our area. Energy-friendly homes are a great place to start,
and have been encouraged by our government through tax incentives. Energy saving
appliances, light bulbs, and heating/cooling units are well known options for
saving money on power bills as well as lessening the impact of inefficient appliances.
Providing incentives for contractors to build efficiently, in the form of builder
certifications and lending packages offered by banks to the consumer, contribute
to a competitive economy as well as conservation efforts. According to Tony
Streible, President of the Rabun County Homebuilders Association, “a builder’s
good reputation is the only reason,” albeit a powerful one, to build energy
efficient homes in Rabun County. Georgia Power and Habersham Electric Membership
Cooperative surveys and tags every house built to establish its efficiency rating,
thereby allowing the homeowner to qualify for an amount of money towards their
power bills.
Making a difference in your lifestyle is the first, and the easiest way, to
bring about a positive impact on the environment. There are many ways to ease
the burden of harmful emissions and wasteful energy habits so the power companies
do not have cause to over-generate power. At home, start by turning off appliances
when not in use. When buying appliances, look for energy-efficient brands. Caulk
and weather-strip so heat and cool air do not leak. Consider catalytic converters
on woodstove pipes to lessen the emissions of wood heaters. Landscaping with
native species can have long-reaching effects by conserving water, cutting fertilizer
use and providing shade in the summer. These are a few general ideas that can
be explored and implemented in the short term.
What technology is around the corner? Will there ever be a revolutionary change
in power generation? Unfortunately, there are no immediate and inexpensive means
to collectively get off “the grid.” The conveniences of electricity provided
by traditional means are too many to list and implicate everyone, whether at
home or work. However, there are ways to generate power in the form of hydrogen
fuel cells, wind power, solar power and many forms of micro power. Some of the
most interesting scientific research is top secret due to claims of ownership.
Patents and copyrights are heavily guarded before new technology appears in
the open market.
Recently an invention known as the Sterling engine, previously used to teach
physics students about highly efficient, low-fuel burning engines, has been
in the news because renown inventor Dean Kaman advanced the design. Kamen’s
patented invention known as “It” or “Ginger” is reportedly his version of the
Sterling engine. The Sterling engine can be purchased on American Sterling Company’s
website (sterlingengine.com) as an aid for physics teachers to demonstrate how
highly efficient power generators operate.
Sterling engines can be powered by the amount of fuel it takes to fill a coffee
cup, and are small enough to fit on top of one. The engine can also be powered
by a variety of heat sources including solar heat. Brent Van Arsdale, president
of American Sterling Company, explains the impact an advanced Sterling engine
could have on society: “Why do I think that this invention could change the
world? Because the current method of delivering electricity is extremely inefficient.
A new power plant will typically burn natural gas, but there are a lot of losses
between the power station and your house. It would be much more efficient to
generate the power by burning the natural gas at your house. That way the waste
heat can be used to heat your water or keep your house warm in the winter. To
keep you cool in the summer, the Sterling engine could drive an optional Sterling
cooler (which is basically a Sterling engine running in reverse). Besides, the
‘refrigerant’ used in the Sterling engine is environmentally friendly helium,
not freon.” Nobody knows for sure when Kamen will reveal his product to the
world, but it is eagerly anticipated.
American Sterling Company also offers waste heat recovery systems to industries,
and they claim to be able to save money for industries by applying the same
Sterling engine principles “to recover power from industrial waste heat sources.”
In addition, the Sterling engine is a cleaner burning engine that could reduce
emissions, thereby helping industrial companies meet current clean air standards.
This is just one example of the many companies offering money saving and energy
efficient solutions to industrial wastefulness.
Fuel cell technology is another example of progressive alternatives to energy
generation issues. There are a wide variety of fuel cell designs, with hydrogen
being the common design element and diversity coming in the form of the catalyst
used to create the energy-producing reaction. The heat released by the chemical
reactions inside the cell manufactures the energy; multiple sets of fuel cells
in a series create a fuel cell stack capable of producing greater amounts of
energy. Determining the type of fuel cell necessary for the application also
depends on how much heat the operating system can bear in extracting the hydrogen
from the source. The catalyst to produce the reaction makes the difference in
the type of fuel cell used, with hydrogen being the common denominator.
The types of fuel cells most commonly used include alkaline, phosphoric acid,
proton exchange membrane, solid oxide and molten carbonate, and the newer methanol
generative system. These fuel cells operate at varying temperatures, which makes
a big difference in the type of systems they can be used in. For example, for
the space shuttle NASA uses alkaline fuel cells with platinum as a catalyst,
rendering it useless for anything else (besides NASA’s budget!)
Converting internal combustion engines to fuel cells is simple and reasonably
priced; however, hydrogen’s extreme combustibility is an issue to be surmounted
for the broad application of this technology. The generation of hydrogen is
another issue. There is not a single solution for this problem; however, the
options reach into solutions for other environmental issues. For instance, making
use of photovoltaic solar panels and biomass technology to generate hydrogen
is a very real possibility. The Sun may be used to start reactions that create
hydrogen as a by-product and that also forms a residue called char, which can
be burned to produce more heat.
Fuel cell technology is already a very real possibility for such power companies
as Tennessee Valley Authority. According to a November 16, 2000 article in the
Knoxville News, TVA has plans for a $25 million plant that will be using fuel
cells to store electricity. The plant will be the first of its kind in the United
States, and will be located on two acres of land near a substation so as to
utilize existing power lines.
Meanwhile, it is up to the local citizenry to seek alternatives to being on
“the grid,” if one so chooses. Many alternative energy possibilities are available,
and are worth researching to see what is right for the Southeast’s climate and
your particular budget. Solar power and wind power have their place, and combining
solar panels and wind turbines may work to meet a household’s electricity needs.
Knowing that fuel cell technologies are vastly improving and will be available
for residential applications in the very near future is encouraging. Transforming
trash and green waste into electricity is on the horizon as well. Using the
gases given off from the breakdown of garbage in landfills, such as methane,
and converting it into usable energy is exciting.
So far there are no limits on consumption in this country for individuals and
corporations. The statistics on American consumption are staggering, and quite
embarrassing. From a global perspective, the United States seems intent on forwarding
oil-based economic principles, and that sends a distinct message to the world.
Yet, the United States has many opportunities to integrate alternative energy
into the fabric of our daily lives. In the meantime, the best option we have
is to conserve energy, and seek and implement alternatives to our current lifestyles
as citizens of the world.
