Is anyone reporting the great dust bowls happening across the U.S. and China as serious? Now what happens when we need 50% more???
Q. You call the last 100 years “the golden age of water,” at least in the developed world. But you also say the golden age is over. As you told Terry Gross, on “Fresh Air,” “We will not, going forward, have water that has all three of those qualities at the same time: unlimited, unthinkingly inexpensive and safe.” Why not?
Mr. Fishman: We’re spoiled. Well-designed, well-engineered water systems were built across the United States and the developed world 100 years ago. They worked so well that they literally helped make creative economically vibrant cities possible, and healthy. And those water systems were so successful they became invisible — and they remain invisible.
We just assume when we turn on the tap, the water will be there, and that the water system buried in the ground is doing fine. - NY Times
Energy's Water Demand: Trends, Vulnerabilities, and Management
Congressional Research Service (CRS) summary:
The nation's energy choices embody many tradeoffs. Water use is one of those tradeoffs.
The energy choices before Congress represent vastly different demands on domestic freshwater. The energy sector is the fastest-growing water consumer in the United States, in part because of federal policies. Much of this growth is concentrated in regions that already have intense competition among water uses. Whether the energy sector may exacerbate or alleviate future water tensions is influenced by near-term policy and investment decisions. These decisions also may determine whether water will limit U.S. capacity to reliably meet the nation's energy demand. Part of the energy-water policy issue for Congress is identifying the extent of the federal role in responding to energy's growing water demand.
Currently, the energy industry and states have the most responsibility for managing and meeting energy's water demand. The energy sector's water consumption is projected to rise 50% from 2005 to 2030. This rising water demand derives from both an increase in the amount of energy demanded and shifts to more water-intense energy sources and technologies. The more water used by the energy sector, the more vulnerable energy production and reliability is to competition with other water uses and water constraints. Climate change impacts that alter water patterns may exacerbate this vulnerability in some regions. While energy's water demand is anticipated to rise across the United States, the West is likely to experience some of the more significant constraints in meeting this demand. Local or regional competition for water often is what makes energy's water demand significant. These local water resources are often consumed to support not only local energy demand but also national demand. Examples of regional water consumption concerns related to energy are shale gas production using hydraulic fracturing in many regions across the nation, solar electricity generation in the Southwest, and biofuel production in the High Plains.
A significant challenge in contemplating a federal response to energy's water demand is that the responses available are not equally needed, attractive, or feasible across the United States. The 112th Congress may see energy's water demand raised in a variety of contexts, including oversight and legislation on energy, environment, agriculture, public lands, climate, and water issues. Alternatives for addressing energy's water demand range from maintaining the current approach to taking a variety of targeted actions. One option is to minimize the growth in energy's freshwater use (e.g., through promotion of water-efficient energy alternatives and energy demand management), which could be accomplished through changes to broad policies or legislation targeted at water use. Another option is to improve access to water for the energy sector. While water allocations and permits generally are a state responsibility, limited federal actions are possible. An additional option is investing in data and research to inform decision making and to expand water-efficient energy technology choices. These policy approaches can be combined. They represent different potential roles and expenses for government, the energy sector, and energy consumers. Legislation considered in the 111th Congress proposes actions that fall under many of these options, including provisions in H.R. 469, H.R. 2454, H.R. 3598, H.R. 1145, S. 1462, S. 1733, S. 3396, and Subtitle IV of P.L. 111-11 (H.R. 146), the Secure Water Act of 2009.

Few facts California Water and Energy connections
- The California State Water Project is the largest single user of energy in California. In the process of delivering water from the San Francisco Bay-Delta to Southern California, the project uses 2 to 3 percent of all electricity consumed in the state.
- The State Water Project burns energy pumping water 2,000 feet over the Tehachapi Mountains -- the highest lift of any water system in the world. The amount of energy used to deliver that water to residential customers in Southern California is equivalent to approximately one-third of the total average household electric use in the region.
- Ninety percent of all electricity used on farms is devoted to pumping groundwater for irrigation.
