Re Digital billboard OK'd for south area (Our Region, Aug. 14): The U.S. Green Building Council determined that a standard digital billboard consumes 397,486 kilowatt hours a year. One digital billboard is responsible for 108.41 tons per year of carbon dioxide. The greenhouse gas emissions from one digital billboard are equal to 49 traditional billboards or 13.39 homes.
It is time to save the earth. The board of supervisors voted greed instead of responsibility.
