Electricity use dips by 3.5% per cent during Earth Hour in Toronto

Toronto went dark to celebrate the importance of energy conservation

TORONTO, March 28, 2015 /CNW/ - Toronto Hydro customers came together this evening to show their support for Earth Hour, as the city's electricity use dipped by 103 Megawatts (MW) or 3.5%

That's equivalent to removing just under 42,000 homes off of Toronto's electricity grid.

Torontonians also showed their love for the earth by taking part in Toronto Hydro's Earth Hour party contest.  Customers who posted photos of their parties to Twitter using the hashtag #EarthHourTO are now eligible to win a $100 Visa prepaid card.  Five winners will be chosen at random on March 31. 

About Earth Hour

Earth Hour is a global environmental initiative in partnership with World Wildlife Fund (WWF), which asks individuals, businesses, governments and communities to turn off their lights to show their support for environmentally sustainable action.  It's been celebrated in Toronto since 2008.
