Bottled Water - Not

"Combining all the energy input totals, Gleick and Cooley found that producing bottled water requires between 5.6 and 10.2 million joules of energy per liter, depending on transportation factors (a typical personal-sized water bottle is about 0.5 liters). That’s up to 2,000 times the energy required to produce tap water, which costs about 0.005 million joules per liter for treatment and distribution.

In 2007, US consumers purchased more than 33 billion liters of bottled water, or 110 liters (30 gallons) per person. The total energy required to produce 33 billion liters is equivalent to 32-54 million barrels of oil (although not all the energy used comes from oil). Energy to produce bottled water accounts for about one-third of one percent of total US energy consumption."
