The Dallas skyline will go dark tonight. The city is one of nine major U.S. cities taking part in "Earth Hour" -- a green initiative to raise awareness about energy efficiency.
At 8:30 p.m. all non-essential lighting in downtown Dallas will be turned off for one hour.
"Watch parties" for the event are being planned in Uptown, Deep Ellum and Oak Cliff including events at the Belmont Hotel and West Village.
"Earth Hour is an opportunity to unite with our neighbors around the globe on a singular issue that is important to us all," said Dallas Mayor Tom Leppert. "This event complements the work we've been doing with our Green Dallas initiatives and is a symbolic way to make a bold statement about Dallas' commitment to the environment."
