Scientists, climatologists and energy experts share a growing concern: the need for water in the production of energy, especially in regions that are experiencing serious drought. Generating power - whether it be from fossil fuels or renewable energy sources - requires large amounts of water.
Nearly all forms of energy production use large amounts of water. Coal, which generates nearly 50 percent of the electricity in the U.S., needs water for mining and transport, and to cool and lubricate equipment.
Water is also used to cool fuel rods at nuclear plants and to generate steam to power turbines. The biofuel industry needs water for irrigation, fermentation and the production of ethanol and biodiesel fuels.
