Topic: Energy and Water

Overview

Energy and Water

Water and energy are interconnected. A frequent term to describe this relationship is the “water-energy nexus.”

Energy for Water: Energy is needed to store water, get it where it is needed and also treat it to be used:

*  Extracting water from rivers and streams or pumping it from aquifers, and then conveying it over hills and into storage facilities is a highly energy intensive process. The State Water Project (SWP) pumps water 700 miles, including up nearly 2,000 feet over the Tehachapi Mountains. The SWP is the largest single user of energy in California. It consumes an average of 5 billion kWh per year. That’s about 2 to 3 percent of all electricity consumed in California
*  Water treatment facilities use energy to pump and process water for use in homes, businesses and industry
*  Consumers use energy to treat water with softeners or filters, to circulate and pressurize water and to heat and cool water
*  Wastewater plants use energy to pump wastewater to treatment plants, and also to aerate and filter it at the plant.

Different end uses require more electricity for delivery than others. Water for residential, commercial and industrial end-use needs the most energy (11 percent), followed by agricultural end-use (3 percent), residential, commercial and industrial supply and treatment (3 percent), agricultural water supply and treatment (1 percent) and wastewater treatment (1 percent), according to the California Energy Commission.

Water for Energy: Water is used to generate electricity

*  Water is needed either to process raw materials used in a facility or maintaining a plant,or to just generate electricity itself.

Overall, the electricity industry is second only to agriculture as the largest user of water in the United States. Electricity production from fossil fuels and nuclear energy requires 190,000 million gallons of water per day, accounting for 39 percent of all freshwater withdrawals in the nation. Coal, the most abundant fossil fuel, currently accounts for 52 percent of U.S. electricity generation, and each kWh generated from coal requires withdrawal of 25 gallons of water.

Should Arizona rethink tax incentives for data centers?

City leaders voted down a data center in Chandler last week, but Arizonans can expect to see even more proposed. The state offers tax breaks for data center projects – significant incentives, Governor Katie Hobbs says, are “clearly working.” On Wednesday, she suggested state lawmakers take another look to find “the right balance.” … Arizona could see big cuts to its allocation of water from the Colorado River, which has been diminished by decades of drought and overuse. Hobbs said she hears the concerns, saying her administration’s Arizona Energy Promise Task Force is looking at how to ensure costs don’t hit consumers. … Water is “part of the conservation, Hobbs said, adding that there’s technology to help data centers reduce their water consumption.

Desert storm: Can data centres slake their insatiable thirst for water?

Surging use of AI has led to a frenzy of construction activity to build new data centres, particularly in the U.S. Estimates put the total number of these facilities in operation worldwide this year at 6,111, with upwards of 2,000 more set to come online by 2030. There has been a lot of focus on the implications for power grids, but less on the toll this unbridled growth will take on a commodity that is in even shorter supply: fresh water. … Periods of prolonged drought, an over-allocation of water supplies from the Colorado River, as well as dwindling groundwater resources make Phoenix a “severely water-stressed region”, according to the Ceres report. If all the data centres now planned come online, the city will experience a 32% increase in annual water stress.

Blog: How contaminated mountain streams could power American-made technology

… [M]etal concentrations in Colorado are increasing over time as warming summer temperatures thaw previously frozen sites containing acid-forming bedrock. This result is alarming from an ecological perspective. If metal concentrations climb too high, they can kill aquatic species, as evidenced by one mountain lake that washed up hundreds of dead fish this summer. But, these increased concentrations may also present an opportunity. That’s according to Baolin Deng and Pan Ni, two distinguished researchers at the University of Missouri’s Missouri Water Center, who are now working to unlock an efficient process capable of extracting rare earths from acid rock drainage.

Westlands approves plan to convert a quarter of its Calif. farmland to solar

The board of California’s largest agricultural water district approved a master plan Tuesday to convert over a quarter of the land in its service area into solar farms, a sign that Central Valley growers are looking for new business as their water sources dry up. The board of the Westlands Water District approved the plan to develop 136,000 acres on the west side of the Central Valley into solar farms, complete with new transmission lines and substations at a Tuesday morning meeting in Fresno. The new master plan, called the Valley Clean Infrastructure Plan, would allow for the development of up to 20 gigawatts of new solar farms, which taken together would be the largest solar installation in the world.

Blog: How much water do AI data centers really use?

… As local and national opposition to data centers has grown, so, too, have concerns about their environmental impacts. Earlier this week, more than 230 green groups sent a letter to Congress, warning that AI and data centers are “threatening Americans’ economic, environmental, climate and water security.” … But as the number of data centers continues to grow across the country — and as President Donald Trump’s administration rolls back environmental protections to encourage more development — it’s worth understanding what, exactly, data centers are using water for, and how popular estimates are produced. And it’s worth having a bigger conversation about how and why we’re choosing to use water to cool data centers in the first place.

Calls for a moratorium on new data centers get louder

The rapid growth and impact of massive data centers, especially for AI and cryptocurrency companies, this year has had big economic benefits, especially for construction and design firms and their workers. … But there’s increasing blowback to that rapid expansion, with more individual communities opting against new data center projects because of their gargantuan need for electricity and water, which is driving utility rates for residential customers higher. That blowback is getting more coordinated as a coalition of more than 230 environmental, tribal and community groups is calling for a national moratorium on such construction.

Data centers are notoriously thirsty. Researchers at Lawrence Berkeley National Laboratory have found that, in 2023, the facilities consumed roughly 17 billion gallons of water for their operations in the U.S. alone. But that’s only a small part of the picture: A much, much larger share of data center water-intensity is indirect, a byproduct of the facilities’ enormous appetites for energy. … However, new research from Cornell University shows that there’s a way to mitigate both the climate and water footprints of these facilities: Build them in places with lots of wind and solar energy.
