Did You Know?

For the first time ever, New York’s Rockefeller Center Christmas tree got its glorious colors from energy-saving LEDs instead of incandescent bulbs. This tree, an 84-foot (25.6-m) Norway spruce, is strung with 30,000 LEDs on 5 miles (8 km) of electrical wire. The LED lights consumed 1,297 kWh of electricity per day, instead of the 3,510 kWh used by the old-fashioned bulbs. The difference is enough to power a 2,000-square-foot (186-m²) single-family home for a month.
