How Energy-Water Data Can Help Cities Conserve Both, on World Water Day and Beyond

flickr broken water pipeToday is World Water Day, an international observance of water’s importance. This year’s theme is “Water and Jobs,” bringing awareness to the fact that nearly half of all workers on Earth (about 1.5 billion people) work in water-related jobs, and virtually all jobs depend on water in some way.

In conjunction with 2016 World Water Day, the nation’s capital is hosting the White House Water Summit. The President has called on organizations from around the country to voluntarily take new, specific, and measurable steps to address key water issues, such as drought or flooding, water availability, water-use efficiency, and water security. EDF heeded that call and made the following commitment:

Environmental Defense Fund (EDF) is announcing a partnership with Pecan Street, Inc. to gather data and conduct analysis to help 50 households in Houston and Austin understand the connection between their water and energy use. Results of this analysis will help Houston and Austin reduce the water and energy footprint of the more than 3 million utility customers in the two cities. In addition, EDF will work with the University of Texas at Austin, the University of Texas at San Antonio, and the University of California, Davis to help water providers of three to five major Texas cities better manage the energy use embedded in their water systems, with an additional one or two states to be announced later this year.

The work laid out here addresses the issue of embedded energy in water systems, or, in other words, the electricity it takes to secure, deliver, treat, distribute, and heat water. (This is part of what’s known as the “energy-water nexus”.) Read More »

On World Water Day, Why Talk About Energy?

The theme of this year’s World Water Day on March 22nd is the “energy-water nexus,” and the timing couldn't be better. According to the United Nations (who first established World Water Day in 1993):

  • 780 million people worldwide lack access to safe drinking water.
  • 1.3 billion people worldwide lack access to electricity.
  • 90 percent of the power generation in the world comes from water-intensive fossil fuels.
  • As countries progress and develop, there is an increased risk of conflict between power generators, other water users, and environmental concerns.
  • By 2035, global water withdrawals for energy are predicted to increase by 20 percent, and water consumption for energy is expected to increase by 85 percent.

For the past year, I’ve been trying to bring awareness to the connection between energy and water in Texas, but this issue is much bigger than a single state. Energy and water are both basic components of life and economic progress, and they are also inextricably linked. Energy is used to secure, deliver, treat, and distribute water, while water is used (and often degraded) to develop, process and deliver energy. Read More »
