Renewable Energy the Key to Rural Electricity, Environmental Stewardship?
October 21, 1997
Greensboro, NC: An engineer with the North Carolina A&T State University School of Agriculture is searching for a common solution to two important energy questions: how to provide electricity to remote areas, and how to provide electricity in an environmentally sensitive way.
"Renewable energy resources are the answer," says Dr. Abolghasem
Shahbazi, associate professor of agricultural engineering. "We have
to find new and better ways of using these resources to produce the energy
we need."
Renewable energy resources, says Shahbazi, are resources in virtually unlimited
supply, versus energy resources which are in limited supply, such as coal
and oil. Common renewable energy resources are the sun, plant material,
wind, and heat produced naturally by the earth.
Shahbazi was recently nominated by Dr. Earnestine Psalmonds, NC A&T's
Vice Chancellor for Research, to work with the Renewable Energy for African
Development project, which is directed by Dr. Leonard Spearman of Texas
Southern University.
In his work with this project, Shahbazi will research ways of improving
the delivery of solar electricity to remote areas of South Africa, as well
as meet with Spearman and other collaborating scientists to initiate a
similar project in the United States.
"The mountains, rough terrain, distance from power sources, and low
levels of usage typifying much of rural South Africa make delivering electricity
through the conventional way of using a line to connect to a power grid
expensive and impractical," said Shahbazi. "Therefore, many people
in these areas do not have electricity even for such basic needs as lighting."
Though even most remote areas in the United States have electricity, U.
S. scientists are searching for more efficient means of delivering electricity
to these areas. That's where Shahbazi's work has a domestic aspect.
Shahbazi offers remote agricultural areas as an example of how renewable
energy technology might be useful in the United States. "Sometimes
a farmer needs an irrigation system in a location far from an energy source,"
said Shahbazi. "In such a case, being able to use something like solar
panels to power the irrigation system would be an ideal solution."
Beyond accessibility and economic issues, the use of renewable energy technology
can address environmental and political issues, such as global warming
and reliance on foreign oil sources, says Shahbazi.
"The burning of fossil fuels, from which the majority of power plants
derive their energy, contributes an abundance of gases to the atmosphere
and leads to destruction of the ozone layer, both of which have been linked
to global warming and erratic weather patterns," said Shahbazi. "Also,
our dependence on oil makes us vulnerable to a number of political situations."
So what stands in the way?
Lowering the costs and enhancing the performance of systems using renewable
energy resources are keys to the success of reducing dependence on nonrenewable
energy resources, says Shahbazi.
To work toward these goals, students and faculty at NC A&T are experimenting
with renewable energy technologies such as solar panels and energy systems
which operate using gas and liquid fuels, such as ethyl alcohol or methane
gas, which are derived from plant and organic material.
In Shahbazi's "Energy Systems in Agriculture" class, for instance,
undergraduate students study the conversion of food waste to ethyl alcohol
and the conversion of animal waste to methane gas.
"Renewable energy sources and agriculture are closely linked,"
said Shahbazi. "And, in a lot of ways, they are dependent on each
other, because farmers both use and produce these sources. If we can make
these sources more attractive options, we can simultaneously lessen environmental
impacts and improve the conditions of rural areas."
