Communities across the United States are dealing with big changes as new AI data centers are being built in their neighborhoods. These massive buildings need lots of power and water to run computers that handle artificial intelligence work. In Pennsylvania, lawmakers passed a bill to make sure data centers pay their fair share of costs to the power grid. In New Jersey, residents in Vineland are worried about a huge data center project that's already under construction, even though city leaders approved it. The Vineland data center will use natural gas engines and could need up to 20 million gallons of water every year, which makes some people nervous about whether there will be enough clean water for everyone. Meanwhile, Colorado towns like Walsenburg are surprised to learn that companies want to put data centers there without asking first. Arizona Senator Mark Kelly is working on new laws to make sure regular people get a say in where data centers are built and what benefits those communities should get in return. Around the world, companies are spending billions of dollars building these data centers - almost $750 billion in 2026 alone. Over 23 gigawatts of data center power is being built right now, mostly in the United States. Cities are trying to figure out how to handle all this change while keeping their communities safe and making sure their power systems and water supplies don't get overloaded.
