With millions of people turning out their lights across the globe for Earth Hour on Saturday night, the city of Calgary, Alberta was just happy that they didn't record an increase in energy use, as they did during last year's inaugural event.
During Earth Hour 2008, Calgary was the only known city in Canada where energy consumption actually went up during Earth Hour, a 3.6 percent spike officials blamed on a cold snap.
But this year, officials with Calgary's utility were happy to see the city's energy use dip about 1 percent, representing a decrease of about 10 megawatts.
“It’s not a significant amount, but at least we went the opposite way this year,” Doris Kaufmann a spokeswoman for the Calgary utility, Enmax, told the Calgary Herald. “It’s not enough to make a huge difference but it’s enough to see that Calgarians made some sort of effort this time around,” said Kaufmann, noting that they still needed to encourage more participation.
In Edmonton, power use is said to have dropped 5 percent and in eastern cities like Toronto, electricity consumption dropped up to 15 percent.
