"Daylight Saving Time saves energy. Based on consumption figures for 1974 and 1975, The Department of Transportation says observing Daylight Saving Time in March and April saved the equivalent in energy of 10,000 barrels of oil each day -- a total of 600,000 barrels in each of those two years."
"The United States consumed an average of about 20.4 million bbl/d of oil during the first ten months of 2004, up from 20.0 million bbl/d in 2003." - http://www.eia.doe.gov/emeu/cabs/usa.html#oil
Lets say we used 50% of 20 million barrels per day in 1975 so 10,000 barrels a day saved us %0.1.
"Daylight Saving Time saves lives and prevents traffic injuries. The earlier Daylight Saving Time allowed more people to travel home from work and school in daylight, which is much safer than darkness. And except for the months of November through February, Daylight Saving Time does not increase the morning hazard for those going to school and work."
No support given so we'll have to take their word for it.
"Daylight Saving Time prevents crime. Because people get home from work and school and complete more errands and chores in daylight, Daylight Saving Time also seems to reduce people's exposure to various crimes, which are more common in darkness than in light."
"Seems to reduce exposure to crime". Again we'll have to take their word for it.
How is the common man supposed to stop this sort of thing, writing letters? Phone calls. "I voted for Kang"!
