Earth Hour

Earth Hour is a global campaign organized by the World Wildlife Fund for Nature (WWF) in an effort to raise awareness about global warming and climate change. It is an annual event that began in 2007 and is held between the hours of 8:30pm and 9:30pm on the last Saturday of March, which was yesterday for the current calendar year. During Earth Hour, households and businesses are encouraged to power off the lights and live in darkness for one hour.


To do its part to be more eco-conscious, Markham took part in a friendly competition with nearby communities served by PowerStream to have the biggest reduction in electricity consumption during Earth Hour compared to last year.


Feeling inspired to make every hour an eco-conscious one? PowerSteam and Markham Energy Conservation Office partner up annually for an Earth Hour event held at the Markham Museum, located at9350 Markham Road. There you can take a tour of the museum's new sustainability measures, such as the geo-exchange heating and cooling system and rainwater harvesting systems, learn about Markham's Sustainability Plan and meet PowerStream's Conservation Team to learn more about energy conservation and how you can reduce your energy consumption at home.
