Daylight Saving — Not Really So Much

This Sunday morning, 2:00 will become 1:00 AM.  This is all part of our semi-annual clock changing ritual.

Daylight Saving Time was instituted to save not daylight, but energy.  The theory goes that during the summer, the extra sunlight in the evening would require less energy use to light our homes.

However, it doesn’t look like the theory holds up–at least not everywhere. A couple of studies have shown that we use more energy during Daylight Saving time.  An Australian study found that the extra energy used in the dark morning hours more than offset any savings in the evening.  A study of Indiana power bills showed another result.  Before 2006, only part of Indiana did Daylight Saving Time.  When the entire state made the switch in 2006, reviews of power bills showed that more power was consumed during Daylight Saving Time.  The cause–more air conditioning time.

California has energy savings of about 1% during DST.

My personal preference would be to always stay on DST.  I don’t mind driving to work in the dark.  I leave the house about 5:45 AM, so it’s dark most of the year anyway.  However, I really enjoy the extra time of daylight in the evening.

Whatever your feelings, be sure to turn your clocks back an hour before you go to bed Saturday night.  If you don’t, you are going to be an hour early for whatever you do on Sunday morning.

    I love having the light at night. We don’t get a whole lot of light here in the winter. I wish summer would stay all year long!
