The coldest winter Ontario has experienced in 20 years is also bringing us a chilly Earth Hour. On Saturday, March 29th Hydro One customers will join millions of people worldwide in conserving energy in support of Earth Hour. Adjusting your home’s temperature down by one degree can make a difference, both for conservation and on your electricity bill. Hydro One customers interested in finding out how much electricity consumption they reduced during Earth Hour can sign up for the Time-of-Use portal at: www.HydroOne.com/MyAccount. Earth Hour reminds us that small acts of conservation can lead to big savings.
