The prevailing wisdom of Daylight Savings Time is that having more time in the afternoon with sun means we’ll leave the lights off longer. That might be true, but it also happens to mean we turn the AC on longer, run our computers longer, and watch TV longer. None of these concerns really weighed heavily on Ben Franklin’s head when he invented the concept. Researchers at USC Santa Barbara have concluded that moving to daylight savings time has cost at leas their study area millions of additional dollars in energy expense. So think of that this weekend when you “spring forward” and loose a hour of precious sleep!
