Daylight Saving Time & Energy Efficiency

This weekend it is time to ‘spring forward’ and start Daylight Saving Time.  This adjustment to the clock was originally planned as a creative way to save energy by Canada and Germany during World War I, and established uniformly in the United States in 1966.  But whether changing our clocks actually saves energy receives mixed reviews.  Most studies conclude that at best is saves very little energy and in fact may actually increase energy consumption.  Our reduced need for lighting in the evenings is offset by greater cooling needs.
