Energy Department Blocks Disclosure of Road Map to Relieve Critical U.S. Energy-Water Choke Points

A far-reaching federal program of research and analysis, funded by Congress and designed to help the nation anticipate and temper the mounting conflict between rising energy demand and diminishing supplies of fresh water, has been brought to a standstill by the Department of Energy, according to government researchers involved in the project.

The research program, known as the National Energy-Water Roadmap and ordered up by Congress as part of the 2005 Energy Security Act, was meant to provide lawmakers and the executive branch two studies of the impending collision between energy and water, and what to do about it.

The first, completed by a team of federal scientists in December 2006 and made public a month later, described the serious consequences the nation is already encountering as the United States encourages more energy production, the second largest user of water, but gives scant consideration to water supplies, which are in retreat in most regions of the country.

Meanwhile the second and final report that Congress commissioned, a comprehensive research agenda to better understand the nation’s energy-water choke points and begin developing real world solutions, has been held out of public view for more than four years.

22 Rewrites

Michael Hightower, an energy systems analyst at Sandia National Laboratories and a co-author of the report, said the first draft of the study on research needs was delivered to the Energy Department in July 2006. Energy Department reviewers have since called for 22 rewrites, the last of which was delivered in May 2009, Hightower said.

Since then the five-member team that co-authored the study has not had any communication about the report with the two primary reviewers, Samuel F. Baldwin, chief technology officer in the DOE Office of Energy Efficiency and Renewable Energy, and Nicholas B. Woodward in the DOE Office of Science.

“I don’t know why they are holding up the report,” said Hightower in an interview with Circle of Blue. “I can only conclude we don’t know how to write or they don’t like the report. I think we have done a nice job in collecting the data. Maybe the quality is in question.”

Neither Baldwin nor Woodward responded to email messages from Circle of Blue. Ebony Meeks, an assistant press secretary, offered this explanation by email and did not respond to follow-up questions: “When developing a comprehensive technological road map it is imperative that all the data is thoroughly reviewed for accuracy and concurred upon by the multiple participating programs. We plan to release the road map as soon as possible.”

The Energy Department’s decision to prevent the report’s public release could also prove embarrassing. A National Water-Energy Conference Without Key Research
The report’s release couldn’t come soon enough for the agency, and the nation. Over the last five weeks, in its Choke Point: U.S. series, Circle of Blue has thoroughly explored the ever more fierce contest between the nation’s insatiable demand for energy, and the tightening supplies of fresh water.

Among the primary conclusions reached in Choke Point: U.S. is that the nation has not yet recognized the significance of the collision between energy demand and water supply to the economy or the environment. The Road Map report was intended to be a vital step toward closing that information gap.

The Energy Department’s decision to prevent the report’s public release could also prove embarrassing. September 26 is the start of the four-day Water/Energy Sustainability Symposium in Pittsburgh, the second annual national conference co-hosted by the Energy Department to “highlight proven and innovative solutions to complex water/energy challenges.” The Pittsburgh conference is the second in a row that could occur without the principal national study that outlines the research priorities. Last year’s conference took place in Salt Lake City.

It is not at all clear why the Energy Department has apparently iced the Road Map. Calls last week to the Senate Energy and Natural Resources Committee, which played an important role in securing funding for the Road Map, received no response.

But a number of clues are contained in a March 2007 Sandia National Laboratories paper that summarized the Road Map’s contents. The paper, prepared by Hightower and three colleagues—Ron Pate, Chris Cameron, and Wayne Einfeld—makes clear that any number of executives in the coal, nuclear, oil, solar thermal, and biofuels industries, and their allies in Congress, could be unhappy about the report’s conclusions. The Sandia paper essentially asserts that the United States quickly needs to reconsider and realign much of its energy production policy and water management practices in order to avoid dire shortages of water and potential shortfalls in energy. None of the big energy production or large water use sectors will be left untouched, the paper indicates.

“The U.S. energy infrastructure depends heavily on the availability of water, and there is cause for concern about the availability of that water as we look toward future demands on limited water resources,” the authors wrote. “As future demands for energy and water continue to increase, competition for water between the energy, domestic, agricultural, and industrial sectors could significantly impact the reliability and security of future energy production and electric power generation,” they added: “It may not be possible in many areas of the country to meet the country’s growing energy and water needs by following the current U.S. path of largely managing water and energy separately while making small improvements in freshwater supply and small changes in energy and water-use efficiency.”

For instance, the authors raised concerns about U.S. energy policy that is encouraging construction of more coal-fired and nuclear power plants, which use millions of gallons of water an hour, without consideration for where they would be built. The thermo-electric generating sector currently accounts for half of the 400 billion gallons of water withdrawn daily from the nation’s rivers and lakes, principally to cool the plants. The same power plants consume more than 3 billion gallons of water a day, principally through evaporation.

The Energy Information Administration, a unit of the Department of Energy, forecast a nearly 50 percent increase in the demand for electricity between 2005 and 2030. A portion will be filled with energy from the wind and solar photovoltaics, which use virtually no water. Most of the rest will come from new thermoelectric plants.

The Sandia authors noted that new technologies are needed to enable the plants to use coolants other than fresh water, including wastewater from municipal treatment systems, seawater, produced water from mining and drilling operations, and agricultural runoff. In addition, the authors said, U.S. policy encouraging the development of pollution control systems that capture climate-changing emissions and store it deep underground–so-called carbon capture and sequestration–increases water consumption at plants 40 percent to 90 percent.
