Tidbit of the day - Drinking Oil

"From start to finish, bottled water consumes between 1100 and 2000 times more energy on average than does tap water.

U.S. bottled-water consumption in 2007 required an energy input equivalent to 32 million to 54 million barrels of oil. Global energy demand for bottled water is three times that amount.

To put that energy use into perspective, Gleick says to imagine that each bottle is up to one-quarter full of oil."
