Some big utility companies are
looking at projects using more renewable
energy. Some are investing in solar on
the rooftops of their customers’ homes. Julie
Grant reports on one of the biggest pilot
projects in the nation:

Duke Energy plans to rent 425 rooftops from homeowners
and businesses in North Carolina to install and maintain
solar panels.

Dave Scanzoni is a spokesman for Duke Energy. He says
building a new nuclear or coal plant could take a decade.
But this solar project could contribute electricity to the grid in
just a couple of years.

“Instead of a big, main baseload power plant that we
traditionally think of, we have several hundred small, little
power plants. It’s distributed power plants, a different way to
distribute energy closer to the customer.”

If the project is approved by regulators, the money to pay for
it will come from ratepayers – an 8-cent hike on the average
utility bill.

Other utilities have rooftop solar projects in the works as
power companies begin to experiment to find ways to reduce
carbon emissions.

Carp Barrier Works Out Another Snag

Two federal agencies say they’ve worked out safety problems that might’ve caused delays at a new electric barrier designed to keep Asian carp out of the Great Lakes. The Great Lakes Radio Consortium’s Chuck Quirmbach reports:


There’s already one underwater barrier at a canal south of Chicago and a second set of electrical cables is being installed. The shipping industry has been worried about the barriers causing safety problems like electrical arcing between vessels. The Army Corps of Engineers and Coast Guard have been working with the private firms and have come up with recommendations to reduce the risk of danger. The suggestions include no mooring, passing, or stopping near the barriers and using wire rope to prevent barges from separating. Coast Guard commander David Fish says the plan should work.


“We think we have something. You get enough people… working on a project… get enough people all wanting the same solution and engineering-wise, we’re able to find a solution.”


But Fish says there are no firm guarantees the second carp barrier will be ready this spring, before the first barrier wears out.
