Although reportedly ‘safe and sane’ energy juice drinks are now alternatively swigged in copious amounts nightly by Paris Hilton and her clan to keep them up all night and partying hearty, it’s nice to know that less juice of yet a different type can also be a good thing in the City of Entertainment.
Although many states reported little or no change in energy use during Earth Hour, officials at NV Energy report that 
energy consumption during the March 28 one-hour event [click on prior Las Vegas Backstage Access articles: 1 2] in the Las Vegas Valley dropped roughly 3 percent below a typical Saturday night.
Although virtually every Las Vegas hotel-casino on the Strip powered down their exterior lights for an hour during that evening, it’s really difficult to accurately determine how much of that power drop might have come from conservation-minded residents turning down or off their lights as the company doesn’t differentiate between power use along the resort corridor and residential consumption.

Las Vegas means business on climate change initiatives and saving energy costs.
