Turns out that springing forward a month early didn’t save any electricity at all in the U.S.

From Reuters:

But other than forcing millions of drowsy American workers and school children into the dark, wintry weather three weeks early, the move appears to have had little impact on power usage.

“We haven’t seen any measurable impact,” said Jason Cuevas, spokesman for Southern Co., one of the nation’s largest power companies, echoing comments from several large utilities.

The reason? Even though people used less energy for lighting at night, they used more for heating and lighting when they dragged themselves out of bed earlier.

Folks in Calgary, however, appear to have saved at least a little — one Canadian dollar per household, on average.
