Amazon Brags About Data Center Water Efficiency, Says Nothing Of Water Demands Of Plants That Power Them

Earlier this year, the e-commerce corporation Amazon secured approval to open two new data centers in Santiago, Chile. The $400 million venture is the company’s first foray into locating its data facilities, which guzzle massive amounts of electricity and water in order to power cloud computing services and online programs, in Latin America — and in one of the most water-stressed countries in the world, where residents have protested against the industry’s expansion.

This week, the tech giant made a separate but related announcement. It plans to invest in water conservation along the Maipo River, which is the primary source of water for the Santiago region. Amazon will partner with a water technology startup to help farmers along the river install drip irrigation systems on 165 acres of farmland. The plan is poised to conserve enough water to supply around 300 homes per year, and it’s part of Amazon’s campaign to make its cloud computing operations “water positive” by 2030, meaning the company’s web services division will conserve or replenish more water than it uses up.

EDIT

To mitigate its impacts in such basins, the company also funds dozens of conservation and recharge projects like the one in Chile. It donates recycled water from its data centers to farmers, who use it to irrigate their crops, and it has also helped restore the rivers that supply water-stressed cities such as Cape Town, South Africa; in northern Virginia, it has worked to install cover crop farmland that can reduce runoff pollution in local waterways. The company treats these projects the way other companies treat carbon offsets, counting each gallon recharged against a gallon it consumes at its data centers. Amazon said in its most recent sustainability report that it is 41 percent of the way to meeting its goal of being “water positive.” In other words, it has funded projects that recharge or conserve a little over 4 gallons of water for every 10 gallons of water it uses.

But despite all this, the company’s water stewardship goal doesn’t include the water consumed by the power plants that supply its data centers. This consumption can be as much as three to 10 times as large as the on-site water consumption at a data center, according to Shaolei Ren, a professor of engineering at the University of California, Riverside, who studies data center water usage. As an example, Ren pointed to an Amazon data center in Pennsylvania that relies on a nuclear power plant less than a mile away. That data center uses around 20 percent of the power plant’s capacity. “They say they’re using very little water, but there’s a big water evaporation happening just nearby, and that’s for powering their data center,” he said.

1. What is the alternative?

2. 1. Stop greenwashing . . .

2. Beats the hell out of me.

If we've collectively decided that Amazon Web Services is more important than water for people, animals and crops in a major city prone to drought, and if we've collectively decided (as Texas apparently has) that power for AI racks is more important than a functioning grid (and is, in fact, worth taking coal plants out of mothballs), then your guess is as good as mine.
