Energy/Water

Water and energy consumption are interdependent – the more water we use, the more energy we need, and vice versa.  In fact, approximately four percent of the nation's electricity is used just for moving and treating drinking water and wastewater. Conversely, it takes 3,000 to 6,000 gallons of water annually to power just one 60-watt incandescent bulb for 12 hours per day.

To help move toward a more sustainable energy and water future, EPA has drafted Principles for an Energy Water Future (PDF) (2 pp, 437K, About PDF). EPA encourages all stakeholders – including government, utilities, private companies and ratepayers – to consider these principles and incorporate them into their work.

The principles are familiar concepts: water and energy efficiency, a water-wise energy sector, an energy-wise water sector, viewing wastewater as a source of renewable resources, integrated resource planning, and maximizing social benefits.   EPA hopes that having them listed in one document that touches upon all aspects of energy and water's interdependency will help to further raise awareness, stimulate discussion and advance progress.
