Daylight Savings Time aims to Save Energy

Daylight Savings Time 2008

animated_clock.gifSpring your clocks forward one hour on March 9th at 2am.  Daylight Savings Time starts 3 weeks earlier to conserve energy nationwide.  One of the primary reasons we change our clocks to Daylight Saving Time (DST) is that the the extra daylight during evening hours can save energy.  Home energy consumption and the demand for electricity for lighting our homes has a direct connection to when we go to bed at night, and when we get up in the morning.  Bedtime for most of us is late evening through the year.  When we go to bed, we turn off the lights and TV.

On average, 25 percent of electric consumption is for lighting and small appliances, such as Tvs, VCRs and stereos.  A high percentage of energy consumed by lighting and appliances occurs in the evening when families are home.  By setting your clock ahead by one hour, homes can reduces the amount of electricity used each day.

A study conducted in the 1970s by the U.S. Department of Transportation concluded that we trim the nations electricity consumption by about one percent EACH DAY with Daylight Saving Time.

Daylight Saving Time creates the illusion that the sun will set one hour later and therefore reduces the period between sunset and bedtime by one hour.  This means that less electricity would be used for lighting and appliances late in the day.
