Without water, energy production will decline
Will Drought Cause the Next Blackout?
By MICHAEL E. WEBBER, NYT
Austin, Tex.
WE’RE now in the midst of the nation’s most widespread drought in 60 years, stretching across 29 states and threatening farmers, their crops and livestock. But there is another risk as water becomes more scarce. Power plants may be forced to shut down, and oil and gas production may be threatened.
Our energy system depends on water. About half of the nation’s water withdrawals every day are just for cooling power plants. In addition, the oil and gas industries use tens of millions of gallons a day, injecting water into aging oil fields to improve production, and to free natural gas in shale formations through hydraulic fracturing. Those numbers are not large from a national perspective, but they can be significant locally.
All told, we withdraw more water for the energy sector than for agriculture. Unfortunately, this relationship means that water problems become energy problems that are serious enough to warrant high-level attention.
During the 2008 drought in the Southeast, power plants were within days or weeks of shutting down because of limited water supplies. In Texas today, some cities are forbidding the use of municipal water for hydraulic fracturing. The multiyear drought in the West has lowered the snowpack and water levels behind dams, reducing their power output. The United States Energy Information Administration recently issued an alert that the drought was likely to exacerbate challenges to California’s electric power market this summer, with higher risks of reliability problems and scarcity-driven price increases.
