We all know about rising levels of carbon dioxide in the atmosphere. And we know
its a problem: most researchers link carbon dioxide emissions with global
warming. But as an industrialized society, can we make energy choices that will
help reduce carbon dioxide levels? What are the costs and consequences of those
choices?
Tough questions to tackle. Undaunted, 15 undergraduates engineering, science,
and social science majors spent the year 2000 exploring solutions.
Their research began with the start of a two-semester seminar called "CAUSE 2000: Energy
Choices for the Millennium." The problem-based seminar, funded by the
Center for Advanced
Undergraduate Study and Experience (CAUSE), is about "students taking the lead in
defining issues," says Semih Eser, one of the instructors.
With Eser and co-instructor Derek Elsworth as their guides,
the CAUSE 2000 students took a hard look at the economic, environmental, political, and
technological factors that will govern our energy choices in the coming years.
"The students were all about renewable sources of energy," says Elsworth. He and Eser
who describe themselves as "conventional energy types" made sure the
students were grounded in the basics of fossil fuels like coal, petroleum, and natural
gas before they explored "renewables" like solar, wind, and geothermal. "We wanted
them to look at the positives and negatives of all different kinds of energy sources,"
Elsworth explains.
At first, Elsworth and Eser broke the class into four energy-supply groups coal,
nuclear, renewable, and petroleum and natural gas. But the students had a different idea.
"We cancelled those groups and made our own based on geographic regions Northeast,
Northwest-macro, Northwest-micro, and Southwest," says CAUSE student Kate Darby, a senior
in chemical engineering. Incorporating the energy-supply idea, each group studied energy
use in one region and presented analyses to the rest of the class during the first
semester of the seminar.
While most of the students mined for data in the library and on the Internet, the highlight
of the seminar and the focus of all CAUSE-funded courses was a group field
trip designed to complement the classroom work.
Because each group was studying a different part of the country, it only made sense that
they wanted to visit their respective regions. But the idea didnt go over well with
the instructors. "This is a student-shaped class, but as arbitrators, we did need to crack
the whip a few times," Elsworth says, laughing. Instead of traveling in separate groups
around the country, the entire class decided to take a two-week "energy tour" of the
western United States during the break between semesters.
