Traffic, street and park lights are the city's biggest users of electricity, accounting for 25 percent of electricity the city uses, Meyers said.
The city is now in the middle of a three-year plan to replace all traffic lights with energy-efficient LED -- light-emitting diode -- lights and have replaced the lights at 10 intersections already, Clough said. Each LED bulb saves an estimated 60 percent from a traditional light.
The Parks Department is similarly trying new types of lights to save energy in Casper parks. Officials switched to induction lighting at Veterans Park last year and has seen a 40 percent to 50 percent energy savings during a two-month period as compared to the same period last year, Clough said. Lights along parts of the Rails to Trails system will be changed within the month and other lighting may be changed out in the future.
Officials think they can achieve 35 percent to 40 percent energy savings for lighting by these measures, Meyers said.
