Just about every hotel I've ever stayed in has had a "conservation" program whereby if you hang your towels, they'll skip washing them. Yesterday I noticed that even though we had hung our towels, they got changed out. Then today we were in the room when housekeeping came by, and even though we had not signalled we wanted a change of sheets by placing the "change the sheets" placard on the bed, she changed the sheets. One would think that a hotel in the middle of the desert would be a little more concerned with water conservation. I also wonder how much this city's temperature is increased by A/C exhaust. I certainly would not be here if there was no A/C, but the amount of energy used and heat exhaused is boggling.
