Conserving water has been an oft-cited strategy to cut down on energy use, and for good reason.

Hot water accounts for up to a quarter of energy use in buildings, and many regions suffer from water shortages. By using less water, energy is saved in both its production and distribution. Strategies to reduce water use include behavior changes such as taking shorter showers, landscaping using plants that need less irrigation (also called xeriscaping), and installing low-flow fixtures and appliances.
