I personally have never liked daylight savings time. I prefer to be in alliance with the sun, and am constantly adjusting myself to the "real" time. It began as a way to save energy and I can go along with that, but now a study shows it actually consumes more energy because it began when lights were the concern, but now heat and air conditioning are perceived as necessities. A study was done in Indiana when a change was recently made and more energy was consumed. No wonder Bush lengthened the time we have it. It is time to eliminate it. It is confusing for one thing. We went through it one weekend in Rome, and again, here. Ridiculous and it uses more energy. It is also time to abolish the electoral college. The popular vote should count, and that would equalize our votes in CA with those in WY.
The electoral college was set up because of slavery. "The southern states liked the fact that their slaves, who would be excluded from a direct vote, would be counted - as three-fifths of a white person - when Electoral College votes were apportioned."
That period of history is now firmly over.
What’s the Point of Daylight Time?
Santa Barbara, Calif.
WHY do we — along with 75 other countries — alternate between standard time and daylight time? Although many people believe it has an agricultural provenance, daylight time has always been a policy meant to save energy. As Benjamin Franklin argued, if people moved up their summer schedules by an hour, they could live by “sunshine rather than candles” in the evenings.
Energy conservation was the motivation for daylight time during World Wars I and II and the oil embargo of the 1970s, and it remains so today — even though there has been little scientific evidence to suggest daylight time actually helps us cut back on electricity use.
Recently, however, we were able to conduct a study in Indiana, where daylight time was instituted statewide only in 2006. Before that year, daylight time was in effect in just a handful of counties. This change of policy offered a unique, natural experiment to measure the overall effect on residential electricity consumption. We could compare the amount of energy used by households in the late-adopting counties during the two years before they switched to daylight time with the amounts they used during the year afterward — while using counties that always practiced daylight time as a control group.
We found that daylight time caused a 1 percent overall increase in residential electricity use, though the effect varied from month to month. The greatest increase occurred in late summer and early fall, when electricity use rose by 2 percent to 4 percent.
Daylight time costs Indiana households an average of $3.29 a year in higher electricity bills, or about $9 million for the whole state. We also calculated the health and other social costs of increased pollution emissions at $1.7 million to $5.5 million per year.
What explains this unexpected result? While daylight time reduces demand for household lighting, it increases demand for heating in the early spring and late fall (in the mornings) and, even more important, for cooling on summer evenings. Benjamin Franklin was right about candles, in other words, but he did not consider air-conditioners.
In regions of the United States where demand for air-conditioning is greater than in Indiana, this spike in cooling costs is likely to be even greater. Arizona, one of the hottest states, may have it right; it does not practice daylight time.
Eliminating daylight time would thus accord with President-elect Barack Obama’s stated goals of conserving resources, saving money, promoting energy security and reducing climate change. At the very least, we should abandon the notion that we are saving energy while enjoying the extra hour of sunlight on hot summer evenings.Matthew J. Kotchen is a professor of economics and Laura E.
