Minneapolis and St. Paul will be among 7,000 cities across the planet that will cut the lights for the annual "Earth Hour" observance, an effort to draw attention to climate change and energy use.
The designated hour is 8:30 to 9:30 p.m. wherever you are in the world, according to the event website. The event was begun in 2007 in Sydney, Australia, and it then grew from a national observance there to an international one, with more than 150 nations now participating. It bills itself as the "largest symbolic mass participation event in the world."
Minneapolis has participated since 2008. City officials will turn off all non-essential electricity in major municipal buildings.
These places will go dim in St. Paul, the city says: state Capitol, City Hall and Ramsey County Courthouse, Landmark Center, Xcel Energy Center, RiverCentre, Rice Park, Saint Paul Central Library, Wells Fargo Place and First National Bank.
Eden Prairie's most visible landmark, the Market Center Water Tower, will also go dark, Patch reports.
