Work has begun to install solar panels on the convention center's roof.
The panels cover 60 percent of the roof and will produce an estimated 725,000 kilowatt hours of electricity. Officials said that will reduce carbon dioxide emissions by about 500 tons annually, which is the equivalent to the carbon dioxide emissions from about 100 passenger vehicles.
"We are thrilled to move forward on this solar energy system," said Mayor Nancy McFarlane. "Making our fantastic Convention Center even more sustainable is a very significant achievement."
When the process is completed in April, the rooftop system will be Raleigh's largest urban solar farm.
