Science Scene - Starbucks going LED
On a light-by-light basis, changing from incandescent to LED only makes a tiny difference in energy consumption and cost, but when you're talking about retrofitting a thousands of Starbucks stores, the energy savings can be huge.
That's just what Starbucks has found now that the replacing of incandescent and halogen lights in 7,000 stores in the U.S. and Canada has been completed. The company's Director of Environmental Impact said that the program is on target to cut lighting energy consumption by 80 percent.
The good folks at Greenbiz did the math and figured that each 1,000 square foot store was saving $600 a year and reducing CO2 emissions equivalent to 10 barrels of oil. The lights also cut total store energy consumption by 7 percent.
