(KSL News) Did last night's "Lights Out" campaign really have any impact? Maybe, says Rocky Mountain Power.
Utahns were asked to shut off their lights between 9 and 10 p.m. Rocky Mountain Power measured usage during that hour and compared it with the same hour the night before. They found no significant change.
However, Rocky Mountain factors in the outside temperature, and it was 10-degrees warmer from 9:00 to 10:00 last night than the night before. So increased air- conditioner use may have offset the power numbers.
