Tanana switches to LEDs for streetlights
July 13, 2010
Small town Tanana, Alaska is off the grid. The city of about 300 people lies 132 mostly roadless miles from Fairbanks, making it easier to reach by airplane than by car.
From the U.S Department of Energy: That means Tanana has to burn diesel to create electricity, pushing up the cost to 76 cents per kilowatt hour – at least 13 times the standard in the lower 48. These high costs make something as simple as powering streetlights very expensive. To save money and energy, Tanana applied for and received a $20,000 Energy Efficiency Conservation Block Grant from the U.S. Department of Energy. The money will allow Tanana to replace its older high-pressure sodium streetlights with newer and more energy-efficient LED streetlights.
“Our streetlights right now use about 150 watts. The two brands we’re looking at, one is a 25-watt brand that produces more light than the 150-watt lights currently do, and the other uses about 38 watts,” says Al “Bear” Ketzler, Tanana’s city manager. “So with either product… there’s a 300 percent savings.” Read more
