- In 1975, a DOT study concluded that an energy savings of 1% was likely. A review of the study by the NBS in 1976 showed no significant changes.
- A 2006-07 Western Australia study showed an over all increase in energy consumption of .06% – DST caused an increase of energy consumption in the hotter days and a decrease in the cooler days.
- (Here’s my favorite…) “A 2008 study examined billing data in Indiana before and after it adopted DST in 2006, and concluded that DST increased overall residential electricity consumption by 1% to 4%, due mostly to extra afternoon cooling and extra morning heating; the main increases came in the fall. The overall annual cost of DST to Indiana households was estimated to be $9 million, with an additional $1.7–5.5 million for social costs due to increased pollution.” Terrific job, Mitch…thanks a lot…
- A 2009 U.S. study found that on Mondays after the switch to DST, workers sleep an average of 40 minutes less, and are injured at work more often and more severely.
- Changing clocks disrupts sleep and reduces its efficiency
- Male suicide rates rise after “falling forward”
- The effects of messing with the Circadian Rhythm can be severe and last for weeks (and I can vouch for MONTHS)
Evelina Marie EEEEEEEEEEEEEKKKKKKKKKKKKKK! I dislike time change so much. *sigh* I lived in Japan for nearly 20 years and was so spoiled without the time change. I can’t get use to it after 15 years. It is like a mass, government ordered jet lag. I’ll feel so out of sync with the rest of the world till we go back to normal time. : ( (emphasis mine)
