Earth Hour began as a one-city initiative in Sydney, Australia in 2007 and is now a global event hosted by the World Wildlife Fund. The annual global event encourages citizens around the world to turn off their lights and power down their electronics for one hour in the evening on the final Saturday in March in an effort to raise awareness about climate change. That was a lower reduction than every year since the event was first observed in Toronto in 2008. Many who lit candles and observed the annual event on Saturday appeared to notice that fewer lights were turned off this year. The drop was far lower than last year, when a six-per-cent reduction was observed, and it was just a fraction of the 15-per-cent savings experienced during Earth Hour 2009. That’s down 77 percent from 2014, when British Columbians saved 65 megawatt hours, and 89 per cent from 2013’s mark of 136 megawatt hours saved.
The city with the largest reduction in electricity load was Whistler at 7.2 per cent, followed by Invermere (6.2 per cent), Clearwater (4.0 percent), Houston (3.9 percent) and Logan Lake (3.2 percent). And in 2008, energy consumption in Calgary famously spiked by 3.6 per cent during earth hour.
