discussing some of the environmental concerns, Bajura
called climate change an "interesting''
people believe in it. Some people don't,'' she said.
she said, is unlikely to prove unequivocally whether the
earth's climate is warming because of greenhouse gases
such as carbon dioxide. But governments and businesses
are acting on their own to lower emissions, she said.
carbon is the heart of coal, dealing with carbon dioxide
emissions is about ?500 million times more complicated''
than cutting back emissions of sulfur dioxide, for
example, Bajura said.
carbon dioxide emissions from coal utilities are a
significant source, Bajura said society has to address
all sources of carbon dioxide, such as transportation,
to reach goals of stabilizing the atmosphere.
said options being considered include going to renewable
energy, improving efficiency and sequestering or storing
DOE, she said, has two demonstration power plants using
a clean coal technology called integrated gasification
combined cycle. The challenge there, she said, is to
reduce the cost and improve reliability and
carbon by capturing emissions at the plant for storage
or storing the gas naturally are other options.
"Sequestration is feasible,'' Bajura said.
"There's clearly plenty of storage capacity

secure, reliable, affordable and environmentally
acceptable,'' Bajura said.
also said a team approach is important for developing an
energy policy. "We need science and technology

he said, the country needs people with a common-sense
approach to the task.
will be part of the energy mix,'' Burns said. Coal is
readily accessible and "we can reclaim behind it,''
the senator said.
country also needs an energy policy that will provide
more spending for alternative fuels. "We've got to
do that. That's part of the mix,'' Burns said.
energy bill currently languishes in Congress, and Burns
said he doesn't know if one would be passed before the
session adjourns. Controversy over MTBE, a gasoline
additive that is harmful to groundwater, "stopped
everything,'' Burns said.
conference is sponsored by the University of North
Dakota's Energy and Environmental Research Center, the
DOE's National Energy Technology Laboratory and the
Electric Power Research Institute. About 150 people from
29 states and five countries are attending.
