The state Capitol Christmas tree will be more environmentally friendly this year. For the first time, the 30-foot-tall artificial evergreen will sparkle with about 2,000 energy-conserving LED lights. The lights should provide an energy savings of 80 to 90 percent over incandescent lamps and should last about 100,000 hours, according to the governor’s press office. Gov. Brad Henry and first lady Kim Henry will light the tree about 6 p.m. Tuesday. The tree is on the south steps of the Capitol. Before that, more than 1,000 students will decorate 42 small Christmas trees scattered inside the Capitol. Tree decorating and other festivities start at 3:45 p.m. Students, ranging from preschool to eighth grade, represent Chickasha, Choctaw-Nicoma Park, Edmond, Flower Mound, Maple, Mid-Del, Millwood, Moore, Oklahoma City, Piedmont, Putnam City, Shawnee, Silo and Yukon school districts. A Girl Scout troop and a Cub Scout troop also are participating. One hundred evergreens throughout the Capitol grounds also will be lighted during the festivities. All the trees in the project were donated by the Weyerhauser Co. Foundation.
