Fossil fuels are also used in the packaging of water. The most commonly used plastic for making water bottles is polyethylene terephthalate (PET), which is derived from crude oil. Making bottles to meet Americans’ demand for bottled water requires more than 1.5 million barrels of oil annually, enough to fuel some 100,000 U.S. cars for a year. Worldwide, some 2.7 million tons of plastic are used to bottle water each year.
