Energy & Water In a Warming World Report


EW3-water-smart-powerThe Southern Alliance for Clean Energy along with partners across the Southeast are working with the Union of Concerned Scientists through the Energy & Water in a Warming World Initiative (EW3) to highlight the energy water nexus.

In July 2013, the EW3 initiative, led by the Union of Concerned Scientists, released a dynamic new report, Water-Smart Power: Strengthening the U.S. Electricity System in a Warming World, which is based on comprehensive new research about the water implications of electricity choices in the U.S. under a range of pathways, at a range of geographic scales. The EW3 research focused on the Alabama-Coosa-Tallapoosa (ACT) and the Apalachicola-Chattahoochee-Flint (ACF) basins in particular.

The report aims to provide critical information to inform and shape decisions about power plants and electricity supply, such that those choices safeguard water resources, reduce power sector carbon emissions, and provide reliable electricity at a reasonable price, even in the context of a changing climate and other water resource pressures.

Water-Smart Power is the second report from the EW3 initiative. The first, released in late 2011, Freshwater Use by U.S. Power Plants: Electricity’s Thirst for a Precious Resource, drew upon new, highly relevant information and methodologies. It used a novel compilation of the water use characteristics of virtually every power generator in the country and new analytical approaches to conservatively estimate the water-supply impacts of power plant cooling and illustrate stress related to high water temperatures. With these tools, the EW3 Initiative characterized the water-stress impacts of power plant water use in the more than 2000 watersheds across the country for 2008.
