Newsom seemingly sided with tech innovation, but legislators say a bill like this would have provided more localities with necessary information to protect water sources.<\/p>\n<p>\u201cThis bill really represents the inflection point between innovation and sustainability,\u201d said Diane Papan, the state assembly member who authored the bill. \u201cI was really trying to reach that balance, especially when you\u2019re talking about a resource like water.

How much do they use in California?<\/strong><\/h2>\n<p>Data centers are buildings that store and process a lot of digital information, like videos, websites and AI programs. Most electricity generation uses water, so data centers indirectly drive large off-site water use. Since the computers get very hot, many data centers use water-based cooling systems to keep them running.<\/p>\n<p>In California, data centers used about 50 billion liters of water in 2023, which is about 20,000 Olympic swimming pools, according to a <a href=\"https:\/\/www.next10.org\/publications\/ai-environmental-public-health-impacts\">new report<\/a> from researchers at the University of California, Riverside. Water use related to California data centers is projected to reach up to about 116 billion liters, or about 47,000 Olympic swimming pools, by 2028, according to the report.&nbsp;<\/p>\n<\/div>\n<\/div>\n<div class=\"wp-block-group has-light-gray-background-color has-background\">\n<div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\n<h2 class=\"wp-block-heading has-white-color has-primary-background-color has-text-color has-background has-link-color wp-elements-cc29d7b4ebbd791d7ba20d81b4b43b9b\"><strong>How will Cal Poly\u2019s new AI Factory address environmental impacts?<\/strong><\/h2>\n<p>Cal Poly is opening a new AI Factory that will use four NVIDIA supercomputing systems to support research and teaching across campus.

From publicly available information, these data centers are relatively small. The facilities are less than 50,000 square feet, according to a data center information <a href=\"https:\/\/www.datacentermap.com\/usa\/california\/san-luis-obispo\/\">aggregate<\/a>. Some large data centers cover hundreds of thousands of square feet.&nbsp;<\/p>\n<p>To put in perspective, the San Luis Obispo data centers are a little smaller than a single football field, but large data centers can be as large as almost 10 football fields, like some in the <a href=\"https:\/\/www.datacentermap.com\/usa\/california\/santa-clara\/vantage-ca3-santa-clara-iii\/\">bay area<\/a>. A company would likely need a special permit for a large data center facility in San Luis Obispo because the city\u2019s <a href=\"https:\/\/www.slocity.org\/government\/department-directory\/community-development\/planning-zoning\/zoning\">zoning rules<\/a> do not list data centers under an existing specific category.<\/p>\n<\/div>\n<\/div>\n<div class=\"wp-block-group has-light-gray-background-color has-background\">\n<div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\n<h2 class=\"wp-block-heading has-white-color has-primary-background-color has-text-color has-background has-link-color wp-elements-2946ec8bb0d1f71ba11fbebaded811c5\"><strong>Could AI affect any of San Luis Obispo\u2019s resources?<\/strong><\/h2>\n<p>The city is not currently facing any imminent water shortages.

And the third reservoir in Salinas filled over capacity.<\/p>\n<p>Even if there is no large data center in San Luis Obispo anytime soon, AI could still affect the city. San Luis Obispo depends on the same statewide electrical grid as the rest of California, and the increasing use of AI could put more strain on the system.<\/p>\n<p>The UC Riverside report shows that AI-driven data centers nearly doubled their electricity use in California between 2019 and 2023 and could drive even greater demand in the years ahead.<\/p>\n<\/div>\n<\/div>\n<div class=\"wp-block-group has-light-gray-background-color has-background\">\n<div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\n<h2 class=\"wp-block-heading has-white-color has-primary-background-color has-text-color has-background has-link-color wp-elements-ccf8f409d28843fc40b734380df3566f\"><strong>How would AB 93 have changed data center water-use transparency?<\/strong><\/h2>\n<p>AB 93 would have required data centers to tell their local water supplier how much water they expect to use, and then report their actual annual water use every year when renewing a business license. The owner would have to self-certify this information under penalty of perjury.<\/p>\n<p>Researchers can estimate how much water data centers use statewide, like in the reports referenced in this article, but these estimates do not show how much water a single facility uses in a specific community.<\/p>\n<p>Companies are not required to report that information publicly as of now, so cities and water districts often lack exact data when approving new projects. The author of the bill hoped to prepare localities for the age of AI.<\/p>\n<p>\u201cI really felt like this was an opportunity to lead and tell the rest of the nation, \u2018hey, data centers may use a lot of water, but this is a way of at least preparing yourselves for that water demand,\u2019\u201d Papan said. \u201cMy feeling is let Texas run out of water.

Lawmakers say this tension will shape future policy, especially as AI drives the need for more data centers. These facilities require large amounts of electricity and water, two resources already under pressure across the state.<\/p>\n<p>\u201cData centers would prefer not to release their individual water or electricity consumption,\u201d State Senator John Laird said. \u201cIf local governments and planners don\u2019t have that knowledge, it\u2019s hard to plan for adequate water or adequate electricity.\u201d<\/p>\n<p>Laird, who represents the northern part of San Luis Obispo County, supported AB 93 and thinks there will still be an appetite for this type of bill in the future. He thinks Newsom\u2019s veto could just be a speed bump.<\/p>\n<p>\u201cWe are also entering a strange period of time where this is about to be the governor\u2019s last year,\u201d Laird said. \u201cWhen the governorship changes, there\u2019s always this big run in the first year to try to do legislation that the previous governor vetoed.
