The West Virginia Department of Environmental Protection (WVDEP) reports that switching thousands of compact fluorescent bulbs to LED bulbs will save the state about $42,000 per year on energy costs for lighting. The agency says it has already changed about 10,000 bulbs at its Kanawha City headquarters to LED bulbs, and the recently constructed field office in Fayetteville has LED bulbs included.
The new LED bulbs have a projected lifespan of almost 50,000 hours. If the light bulbs are turned on for 8 hours per day, five days per week, that translates to a projected lifetime of about 20 years. The WVDEP bought the bulbs for $118,000. However, thanks to a $28,376 rebate from Appalachian Power the total investment in this project is about $90,000.
WVDEP Expects $42,000 annually in Energy Savings
With an estimated $42,000 per year in energy savings for the lighting, the new LED bulbs are expected to pay for themselves in energy savings alone in just two to three years. WVDEP expects additional savings in relamping and maintenance costs.
According to the agency, the bulbs that were taken out of its headquarters are now being utilized in other state office buildings.
“This project shows how the simplest changes can make a huge difference both for the amount of energy that is consumed and how much money is spent by the state,” said WVDEP Cabinet Secretary Austin Caperton. “The WVDEP not only talks the talk but also walks the walk when it comes to helping to save energy and make sure that we are good stewards of the taxpayers’ money.”
