In the oil crisis of the 1970s, the US Department of Transportation studied the impact of daylight savings time on national electricity usage, and found that it reduced use of electricity by roughly 1 percent.

Just a few of their cited findings included that in Australia and the United States, daylight savings time might actually be increasing electricity usage. Why? By shifting what parts of the day we align our lives with, daylight savings time tends to increase usage of air conditioning and heating.
One study found that it does tend to smooth out the peaks and valleys of electricity usage a bit, but still leads to overall higher usage. Another study found that fewer muggings and sexual assaults happen during daylight savings time months because there aren’t as many people out after dark.
The rest of the studies, though, are mostly based on sleep deprivation. There’s more injurys, more accidents, more lost productivity… the fairly standard combination of nastiness that happens when you have a general state of sleep deprivation.
