If you are out for a night of fun this Saturday in Atlantic City, you'll be sure to notice a dimming of the lights at the Caesars Entertainment casinos.

No, the casinos aren't going out of business, or "dark", as they say, but they will putting off a lot less light for an hour.

Saturday night, from 8:30 to 9:30pm, the casinos will shut off their exterior lighting and nonessential interior lighting to help promote climate change awareness.

The Caesars properties, including Caesars, Bally's, Harrah's and Showboat will be take part in the annual World Wildlife Fund "Earth Hour" event to draw attention to climate change.

According to Gwen Migita, vice-president of Sustainability and Community Engagement for Caesars Entertainment, Saturday's Earth Hour is just one of many ways the casino company encourages employees and guests to make a habit of turning off unnecessary lights and equipment.

Of course, at 9:30pm Saturday, Earth Hour will end and the Atlantic City night sky will again light up brightly.  In the casino business, it doesn't pay to leave the lights off for very long.
