A recent meta-analysis of energy savings due to daylight-saving time found a 
mean effect close to zero (the weighted mean of 0.343% was less than the 
estimated standard error). The largest energy savings from DST was found in 
high-latitude countries; areas closer to the equator tended to have negative 
energy savings. Studies published in journals with high impact factors tended to 
be more pessimistic about energy-savings benefits. The study concluded, "the 
effects of daylight saving time on energy consumption are too small to justify 
the biannual time-shifting."
