In response to a growing backlash, Microsoft said it would take steps to ensure that data centers don't raise utility bills in surrounding areas and address other public concerns. A Microsoft data center in Aldie, Virginia.Photograph: Bloomberg/Getty Images Microsoft said on Tuesday that it would be taking a series of steps toward becoming a "good neighbor" in communities where it is building data centers--including promising to ask public utilities to set higher electricity rates for data centers. Speaking onstage at an event in Great Falls, Virginia, Microsoft vice chair and president Brad Smith directly referenced a growing national pushback to data centers, describing it as creating "a moment in time when we need to listen, and we need to address these concerns head-on." "When I visit communities around the country, people have questions--pointed questions. They even have concerns," Smith said, as a slide showed headlines from various news outlets about opposition to data centers.

Fears about AI data centers' water use have exploded. Experts say the reality is far more complicated than people think. Last month, journalist Karen Hao posted a Twitter thread in which she acknowledged that there was a substantial error in her blockbuster book Empire of AI. Hao had written that a proposed Google data center in a town near Santiago, Chile, could require "more than one thousand times the amount of water consumed by the entire population"--a figure which, thanks to a unit misunderstanding, appears to have been off by a magnitude of 1,000. In the thread, Hao thanked Andy Masley, the head of an effective altruism organization in Washington, DC, for bringing the correction to her attention. Masley has spent the past several months questioning some of the numbers and rhetoric common in popular media about water use and AI on his Substack.

Things to Do in L.A. A data center stands in downtown Santa Clara. This is read by an automated voice. Please report any issues or inconsistencies here . Gov. Gavin Newsom vetoed a bill that would have tracked data centers' growing water footprint in California. He says California is "well positioned" to support the data center boom, and he is reluctant to "impose rigid reporting requirements."

As demand for artificial intelligence technology boosts construction and proposed construction of data centers around the world, those computers require not just electricity and land, but also a significant amount of water. Data centers use water directly, with cooling water pumped through pipes in and around the computer equipment. They also use water indirectly, through the water required to produce the electricity to power the facility. The amount of water used to produce electricity increases dramatically when the source is fossil fuels compared with solar or wind. A 2024 report from the Lawrence Berkeley National Laboratory estimated that in 2023, U.S. data centers consumed 17 billion gallons (64 billion liters) of water directly through cooling, and projects that by 2028, those figures could double - or even quadruple.

"It's not going to completely replace the human element of putting your boot into the vineyard, and that's one of my favorite things to do," he said. "But it's going to be able to allow you to work more smartly, more intelligently and in the end, make better decisions under less fatigue." Gamble said he anticipates using the tech as much as possible because of "economic, air quality and regulatory imperatives." Autonomous tractors, he said, could help lower his fuel use and cut back on pollution. As AI continues to grow, experts say that the wine industry is proof that businesses can integrate the technology efficiently to supplement labor without displacing a workforce.

In response to climate change, assessing crop productivity under extreme weather conditions is essential to enhance food security. Crop simulation models, which align with physical processes, offer explainability but often perform poorly. Conversely, machine learning (ML) models for crop modeling are powerful and scalable yet operate as black boxes and lack adherence to crop growths physical principles. To bridge this gap, we propose a novel method that combines the strengths of both approaches by estimating the water use and the crop sensitivity to water scarcity at the pixel level. This approach enables yield loss estimation grounded in physical principles by sequentially solving the equation for crop yield response to water scarcity, using an enhanced loss function. Leveraging Sentinel-2 satellite imagery, climate data, simulated water use data, and pixel-level yield data, our model demonstrates high accuracy, achieving an R2 of up to 0.77, matching or surpassing state-of-the-art models like RNNs and Transformers. Additionally, it provides interpretable and physical consistent outputs, supporting industry, policymakers, and farmers in adapting to extreme weather conditions.

This story was originally published by Yale E360 and is reproduced here as part of the Climate Desk collaboration. Two months after its release in November 2022, OpenAI's ChatGPT had 100 million active users, and suddenly tech corporations were racing to offer the public more "generative AI" Pundits compared the new technology's impact to the Internet, or electrification, or the Industrial Revolution--or the discovery of fire. Time will sort hype from reality, but one consequence of the explosion of artificial intelligence is clear: this technology's environmental footprint is large and growing. AI use is directly responsible for carbon emissions from non-renewable electricity and for the consumption of millions of gallons of fresh water, and it indirectly boosts impacts from building and maintaining the power-hungry equipment on which AI runs. As tech companies seek to embed high-intensity AI into everything from resume-writing to kidney transplant medicine and from choosing dog food to climate modeling, they cite many ways AI could help reduce humanity's environmental footprint.

The focus of my research is an agent-based system for optimizing spatial arrangements of plants on a landscape to maximize their growth and minimize their water use. The optimization criteria include a natural phenomenon known as facilitation, which is observed in water-scarce environments when larger shrubs serve as benefactors to smaller annuals by generating conditions that protect them from harsh afternoon sun. In my modeling and optimization system each plant is an agent with growth requirements. A plant agent's fitness at a given location is defined by a fitness function that includes those growth requirements and a penalty term designed to force facilitation. The landscape design is formulated as a combinatorial optimization problem with a discrete set of locations for each plant on a grid, a fixed number of plants, and a fitness function that defines the performance of a plant at a location. To evaluate the effectiveness of this approach, I applied a variety of search strategies, including simulated annealing and a new agent-based approach that mimics how plant communities evolve over time, to different collections of simulated plant types and landscapes and compared the fitness scores and spatial arrangments in the solutions. The fitness scores from the search strategies were comparable. The search strategies produced different spatial distributions of the larger plants, and all designs exhibited facilitation and lower water use.

Kohler has revealed when you'll be able to snag the Stillness Bath it unveiled at CES 2021, as well as a number of other smart home products. The bath, which takes inspiration from Japanese forest bathing, aims to replicate a spa experience with the help of light, fog and aromas. All aspects of the experience can be controlled through Kohler's Konnect app. The Soak Freestanding Bath model will cost around $8,000 and you'll be able to order it by the end of March. Another model offers voice control and another, called the Infinity Experience, fills from the bottom and water overflows into the wood base.

One of the challenges of aerial imagery, whether from an airplane or a satellite, is making sense of what you see. What is that image telling you? Ceres Imaging, a California startup with offices in Nebraska and Washington, is using artificial intelligence to answer that question. The company is entering its ninth crop season of providing high-resolution crop imagery for customers. However, John Bourne, vice president of marketing, Ceres Imaging, says the company wanted to work on ways to "productize" the good science it was developing, so three years ago it brought artificial intelligence technology to irrigation issue identification.
