Bottled water consumption has skyrocketed over the past several years. In 2007, some 200 billion liters of bottled water were sold worldwide, and Americans took the biggest gulp: 33 billion liters a year, an average of 110 liters per person. That amount has grown 70% since 2001, and bottled water has now surpassed milk and beer in sales.
And that’s bad because from start to finish, bottled water consumes between 1100 and 2000 times more energy on average than does tap water. This includes how much energy goes into making a plastic bottle; processing the water; labelling, filling, and sealing a bottle; transporting it for sale; and cooling the water prior to consumption.
