Many families will turn out the lights and perhaps turn off the television and computers as well between 8.30 and 9.30 p.m in the tenth annual observance of Earth Hour. It is a conscientious act — often inspired by children in the family — to remember the need to conserve. Still, some people of good will find Earth Hour less than compelling. In Calgary, there is hardly a blip in the power demand. Calgary Herald A number of neighborhoods will make it a public occasion. There is a Beaches Earth Hour Lights Out and at the University of Toronto there will be a lecture on what it would be like if the earth were no longer habitable. Hmm. Reuters reports that more than 350 landmark buildings across the world including the Eiffel Tower, the Empire State Building and Taipei 101 will be darkened. In Australia, where Earth Hour has come and gone, this year’s theme is a celebration of “Places We Love,” such as beaches, forests, reefs, snow-capped mountains and rivers which could be at risk from climate change. Organizers say they hope this year’s Earth Hour can tap a “new momentum” in climate action following world leaders’ Paris agreement in December. That agreement set a course for global carbon emissions reduction to a net zero by 2100, shifting from fossil fuels in favor of greener energies such as solar and wind power.
