Energy Study: Moving Clocks Forward a Waste

Israel moves it clocks forward at 2 a.m. Friday morning, but Daylight Savings Time ("summer time") wastes more energy than it saves, according to research in the state of Indiana. As recently as two years ago most of Indiana's counties refused to move their clocks forward in the spring. The resulting division of the population enabled researchers to compare energy use by those on summer time with those who did not change their clocks.

Residential electricity usage actually increased between 1-4 percent, and social costs from increased emissions were estimated at between $1.6 million and $5.3 million per year, according the research by University of California economics professor Matthew Kotchen. The reduced cost of lighting in afternoons during daylight saving time was more than offset by the higher air conditioning costs on hot afternoons and increased heating costs on cool mornings.
