Several years ago, I naively asked the energy manager of a well-known Las Vegas casino about the facility's energy conservation strategies. The energy manager had taken a colleague and I behind the scenes to see the casino's heating and cooling operation and its electrical systems.
We talked about loads and capacities, and I looked through new eyes at the energy demands of a casino. There really are too many lights to be counted, especially if one considers the support areas, the entertainment spaces, and the guest rooms. I didn't stop to calculate the heat load from these lights, probably because we were moving through comfortably cool spaces even though the outside temperature exceeded 90[degrees]F.
As we moved further away from the glitzy casino area, I anticipated seeing sophisticated control or peak shaving strategies at work reducing the casino's energy losses. But I soon learned, somewhat to my disappointment, that even with the relatively large energy loads of a casino, other economic rules took precedence:
Rule 1: Keep the patrons happy. At a casino, reliability on the gambling floor takes first priority--even over comfort in the rooms. In a real pinch, guests could abandon their rooms and take refuge near the craps tables, where there would be light and air conditioning--and the lure to pour more dollars into the casino's coffers.
Rule 2. Power is cheap. The casino saw no reason to violate rule I to save a few dollars in energy costs.
In the end, I saw that the casino hadn't spent a lot of time seeking opportunities to cut energy use or costs. There weren't any sophisticated controls, and although the equipment was new--and therefore more efficient--there were no signs that energy costs were a significant issue.
I tell this story today only because news reports say that Las Vegas could be blacked out for lack of power this summer--and no amount of casino money will make power available.
