A group that promotes environmental sustainability is working with Charlotte employers, residents and governments to encourage people to turn off their lights for one hour.
    
Envision Charlotte wants people to turn off their lights from 8:30 p.m. to 9:30 p.m. Saturday as part of Earth Hour, known as the world's largest public environmental action.
    
In Charlotte, participants include Duke Energy Center, One Wells Fargo, Bank of America Corporate Center, and the Hearst Tower. In a letter last month, Mayor Anthony Foxx challenged all Charlotte-area businesses to join the effort.
    
Mecklenburg County will turn out lights at the Civil Courthouse, the County & Courts Office Building, the New Courthouse, and the Judge Clifton E. Johnson Building.  The City will turn out lights at the Charlotte-Mecklenburg Government Center and Old City Hall.
