Toronto's electricity use dropped by 2.8% during Earth Hour

Result is lower than last year's event, which saw a dip of 3.2%

TORONTO, March 25, 2017 /CNW/ - Toronto Hydro customers marked the 10th anniversary of Earth Hour by switching off to help the environment. The city's electricity use dipped by 77 megawatts (MW) or 2.8%.

That's the equivalent to removing approximately 31,000 homes off of Toronto Hydro's grid.

Toronto Hydro would like to thank its customers for participating in Earth Hour and for practising smart electricity use habits throughout the year.
