About.com explains the necessity of conserving water by describing the Earth's finite water supply, of which only 1 percent is viable for drinking. With everyone on the planet relying on such a small amount of water, conserving it whenever possible is vital for the future of humanity.

Intelligent Utility warns that energy production relies on water, and it is likely that the demand for energy is going to continue to increase. Clean energy such as biofuels require especially large quantities of water, potentially worsening water pollution, but solar power and wind are two forms of clean energy that do not make the situation worse, according to Intelligent Utility. The fact that water is so important in the production of energy means that preserving it goes far beyond ensuring there's adequate drinking water.

Intelligent Utility states that fossil fuel generation is responsible for roughly 136 billion gallons of water each day in the United States. Water is used to extract the fuels that enable the generation of electricity, making electricity one of the worst drains on the planet's water supply. Conserving water directly conserves energy, which enables humanity to allocate resources into solutions that stand to preserve water in the long run, according to Intelligent Utility.
