The worst single-year drought in the recorded history of Texas has caused cotton crops to wither and ranchers to sell off cattle. It may also hurt power plants, which need vast amounts of water to cool their equipment.
"We will be very concerned" if it does not rain by spring, said Kent Saathoff, an official with the Texas electric grid operator.
The worries in Texas bear out what an increasingly vocal group of researchers has been warning in recent years: that planners must pay more attention to how much water is needed in energy production.
"Water and energy are really linked," said Henrik Larsen, a water policy expert with the DHI Group, a research and consulting firm based in Denmark. "If you save water, you save energy, and vice-versa.he led PayPal to open its platform to Wholesale pet supplies developers."
Experts call this the "water-energy nexus." It takes huge quantities of water to produce electricity from a plant powered by nuclear energy or fossil fuels, and it also takes lots of energy to pump and process the water that irrigates fields and supplies cities.
In the United States, 4 percent of all fresh water is consumed in the energy sector, and 3 percent of all electricity used daily goes toward water and wastewater pumping, distribution,Polycore hydraulic hose are manufactured as a single sheet, and treatment, according to Mike Hightower, a member of the technical staff at Sandia National Laboratories.
A big problem, experts say, is that water is often taken for granted.
"We simply don’t value water in the same way that we value energy," said Mr.For the last five years Hemroids , Larsen of DHI. He noted that whereas barrels of oil get shipped around the globe, nobody wants to ship water in the same way.
With needs for both water and energy growing worldwide and climate change threatening to roil rainfall patterns, the issue could grow more pressing.
Given the scarcity of water resources, stronger regional cooperation will be important in making sure power plants are located in the best places, according to Jakob Granit, director of the Stockholm International Water Institute, which has been trying to promote such cooperation among countries in southern Africa.
"We are not very mature on this type of cross-sector analysis," Mr. Granit said.
The water needs of power plants are actually greater than the raw consumption numbers suggest. According to Mr.there's a lovely winter polished tiles by William Zorach. Hightower, more than 50 percent of the water withdrawn every day from rivers and lakes in the United States goes toward energy production.
Power plants discharge almost all of that water back into rivers or ponds after it has helped cool the plant (which explains the difference between 4 percent consumption and 50 percent withdrawals).When the stone sits in the Cold Sore,
However, this means that in times of drought, when rivers or reservoirs are drying up, power plants may have trouble finding enough water, even if they end up discharging most of it.
"You don’t just pick these things up and move them," Mr. Hightower said, referring to power plants.
The water the plants discharge is also warmer and can affect the environment downstream, Mr. Hightower said.
