Last year a large study found daylight savings time does save a small amount of energy. While that’s interesting, it doesn’t tell the whole story: variations in local power consumption are important. In Victoria, changing the clocks increases energy consumption. Then there are the health costs: Swedish researchers found that “the number of heart attacks rose about 5 percent during the first week” of DST, while Australian workers increase their risk of skin cancer. (In case you haven’t picked it up, I don’t much like this daylight savings business. If I was still in WA, I’d vote no.)
