our electric cooperative appetite requires a Diverse Energy Menu
Were in the middle of a green
revolution in America, with towering wind turbines and bright solar arrays
dominating headlines as the future of electric generation. No doubt these
technologies will take on a bigger role in keeping the lights on.
But despite media hype, they wont totally replace conventional
sources for producing electricity, such as coal, natural gas, and nuclear
power, any time soon.
To meet growing demand for
electricity, electric co-ops will continue to mix and match generation
resources, finding the best way to balance environmental concerns while
ensuring delivery of affordable and reliable power. And because federal
climate change legislation will likely boost the price for every kilowatt
generated by fuels that emit carbon dioxide notably coal and natural
gas nuclear power may very well become an attractive option once
For starters, nuclear power doesn't
release carbon dioxide into the air. Its also reliable (available
24/7), unlike other renewable energy options that are dependent on breezes
or daylight. In the past, nuclear power has faced opposition because of
waste and safety concerns. However, commercial nuclear reactors have been
operating since the 1950s, and most problems have been worked out. In
addition, other countries have jumped on the nuclear bandwagon in a big
way, and perfected the technology. Over the past 40 years, for example,
France has replaced all of its coal-fired power plants with nuclear power
stations and in the process recycled the radioactive waste created, using
it over and over again as fuel.
In the United States, largely because
of added construction costs imposed on nuclear plants following the Three
Mile Island accident in 1979, no new nuclear facilities have been ordered
and built from scratch since 1973. However, utilities are ready to break
ground on 26 nuclear reactors in 16 states, with another 11 reactors in
the planning stages. These new reactors will run much more efficiently,
generate more power, and boast lots of new safety features.
Even with a nuclear renaissance, coal
will remain a keystone of electric power in the U.S. More than half of the
nations electricity is generated by coal; the goal is to burn it as
cleanly as possible. One of the most promising options involves carbon
capture and storage (CCS), where CO2 emissions are pulled out before
theyre released up a power plant smokestack.
Large-scale CCS technology is just now
being tested, and wont be commercially viable for at least a decade, if
not longer. But CCS may become a cost-effective option as co-ops focus on
research and development to lower costs.
So the next time you hear someone talk
about nuclear power or clean coal, remember both of these fuels are key to
keeping power affordable and reliable. We will have to mix and match our
resources if we want to find a balanced, sustainable solution for our
