The U.S. Needs More Nuclear Power To Fuel the Artificial Intelligence Boom
The Department of Energy also expects data centers' energy use to balloon. A December 2024 report forecasts that cloud computing will account for as much as 12 percent of the nation's annual energy use by 2028—up from 4.4 percent in 2023. Virginia, California, and Texas will each serve as a "primary hub" for both small- and large-scale cloud data centers, according to the Energy Department.
Texas is the fastest-growing consumer of electricity in the nation, according to the Energy Information Administration. In 2024, the Electric Reliability Council of Texas (ERCOT)—which manages about 90 percent of the state's grid—said electricity demands could nearly double by 2030 as data centers and cryptocurrency grow and as oil operations in the Permian Basin begin to run on electricity instead of diesel. In March, ERCOT said it has received requests for 99 gigawatts (GW) of new connections—enough to power almost 25 million homes—from large power users (including data centers) in the past year. The state will need to add the energy equivalent of 30 nuclear power plants by 2030 to meet demand, reports Bloomberg.
Last Energy is preparing to deliver 30 such reactors—microreactors, that is. In February, the company announced plans to build 30 of its 20-megawatt reactors in Haskell County, Texas, to service data centers across the state. The site is conveniently located 200 miles west of Dallas, where data centers are expected to add 43 GW of demand to the grid through 2029.
The company has filed for a grid connection with ERCOT, which takes about 18–30 months to complete, according to the regulator. Last Energy is also in the process of applying for an Early Site Permit with the Nuclear Regulatory Commission (NRC). Once obtained, the company will have a 10–20 year window to build its reactors.
This will be Last Energy's first operational project in the United States. Despite being an American company, Last Energy has focused on growing its business abroad because of stringent federal regulations. The developer sued the NRC in December 2024, challenging an agency rule requiring all nuclear power–producing entities—including those that do not generate enough electricity to turn on a lightbulb—to obtain an operating license from the commission before turning on.
Texas isn't the only state turning to nuclear power to meet its data center demand. In Virginia, where data centers could double the state's power demands by 2034, Amazon is partnering with Dominion Energy to develop three new nuclear energy projects. Three Mile Island in Middletown, Pennsylvania, is restarting to provide energy to Microsoft's data servers. The power plant was shut down in 2019.
These efforts will only be as cost-effective and efficient as regulations allow. But the renewed interest in clean and reliable nuclear power could allow the U.S. to make advancements in AI with minimal greenhouse gas emissions.

Maryland's first-in-the-nation tax on digital ads violated Big Tech's free speech, judges say
ANNAPOLIS, Md. (AP) — Maryland's first-in-the-nation tax on digital advertising violated the Constitution, a federal appeals court says, because blocking Big Tech from telling customers about the tax violates the companies' right to free speech. Supporters say Maryland needed to overhaul its tax methods in response to significant changes in how businesses advertise. The tax focuses on large companies that make money advertising on the internet such as Meta, Google and Amazon, who say they're being unfairly targeted. The ongoing legal fight is being watched by other states that are considering taxes for online ads. Maryland estimated the tax could raise about $250 million a year to help pay for a sweeping K-12 education measure. Maryland's law says the companies must not only pay the tax, but avoid telling customers how it affects pricing, with no line items, surcharges or fees, said the appeals court Friday in siding with trade associations fighting the tax. Judge Julius Richardson cited the Colonial-era Stamp Act, which helped spark the Revolutionary War, and wrote that 'criticizing the government — for taxes or anything else — is important discourse in a democratic society.' The plaintiffs contended Maryland lawmakers were trying to insulate themselves from criticism and political accountability by forbidding companies from explaining the tax to their customers. 'A state cannot duck criticism by silencing those affected by its tax,' the judge wrote. The unanimous ruling by the 4th U.S. Circuit Court of Appeals reverses a decision by U.S. District Judge Lydia Kay Griggsby and sends the case back to her with instructions to consider an appropriate remedy in light of the panel's decision. Trade groups praised the decision. 'Maryland tried to prevent criticism of its tax scheme, and the Fourth Circuit recognized that tactic for what it was: censorship,' said Paul Taske, co-director of the NetChoice Litigation Center, said in a statement. The law imposes a tax based on global annual gross revenues for companies that make more than $100 million globally. Under the law, the tax rate is 2.5% for businesses making more than $100 million in global gross annual revenue; 5% for companies making $1 billion or more; 7.5% for companies making $5 billion or more and 10% for companies making $15 billion or more. The law has been challenged in multiple legal venues, including Maryland Tax Court, where the case is ongoing. The Maryland General Assembly, which is controlled by Democrats, overrode a veto of the legislation in 2021 by then-Gov. Larry Hogan, a Republican. Brian Witte, The Associated Press

OpenAI CEO Sam Altman warns of AI bubble, says investors are ‘overexcited': report
OpenAI CEO Sam Altman warned that the billions of dollars being plowed into the artificial intelligence arms race risks causing a bubble comparable to the dot-com crash of the early 2000s. 'When bubbles happen, smart people get overexcited about a kernel of truth,' Altman said during a dinner with a group of journalists, The Verge reported on Friday. 'Are we in a phase where investors as a whole are overexcited about AI? My opinion is yes. Is AI the most important thing to happen in a very long time? My opinion is also yes.' Advertisement 4 OpenAI CEO Sam Altman testifies before a Senate Committee on Commerce, Science and Transportation. AP Altman likened the AI funding rush to 'the tech bubble,' when investors 'got overexcited' about internet-based companies in the late 1990s. Between March 2000 and October 2002, the Nasdaq lost nearly 80% of its value after many of these online companies failed to turn a profit. Advertisement In a report released last month, Torsten Slok, head economist at Apollo Global Management, argued that the AI bubble is actually bigger than the internet bubble, with the top 10 companies in the S&P 500 more overvalued than they were in the late 1990s. Ray Wang, research director for semiconductors, supply chain and emerging technology at Futurum Group, took a more optimistic stance. 'From the perspective of broader investment in AI and semiconductors… I don't see it as a bubble. The fundamentals across the supply chain remain strong, and the long-term trajectory of the AI trend supports continued investment,' he told CNBC in a statement. However, there is a high amount of speculative capital being thrown at companies who only have perceived potential – which could lead to pockets of overvaluation, Wang added. Advertisement 4 OpenAI chief Sam Altman likened the AI funding rush to the internet bubble of the early 2000s. REUTERS 'Calling it a bubble is too simplistic. What we're really seeing is a supply chain bottleneck – too much capital with real need, chasing too little compute,' Kyle Okamoto, chief technology officer at Aethir, a decentralized cloud GPU network, told The Post on Monday. 'Until infrastructure catches up, prices and hype will stay inflated, but that's not a bubble bursting – that's a market maturing.' Fears that the US might be in an AI bubble grew earlier this year after the explosive rise of DeepSeek, a Chinese tech firm that claimed to make a competitive AI model with a fraction of the time and money it took American rivals. Advertisement DeepSeek said its AI chatbot had been trained for under $6 million, far below the billions spent by US counterparts. OpenAI is on track to pass $20 billion in annual recurring revenue but it remains unprofitable, Altman said earlier this month. 4 OpenAI is on track to pass $20 billion in annual recurring revenue, but it remains unprofitable, according to Altman. AFP via Getty Images Its recent launch of ChatGPT-5 was so disappointing that customer complaints pushed the company to go back to the drawing board while reverting to the GPT-4 model. During the dinner with reporters, Altman said the term artificial general intelligence, or 'AGI,' is losing its relevance. AGI refers to a form of AI that can perform any intellectual task that a human can – which Altman previously said could be achieved in the 'reasonably close-ish future.' Altman's startup continues to draw in big investments. In March, OpenAI raised $40 billion at a $300 billion valuation – far above the largest amount ever raised by a tech company. Advertisement It now is preparing to sell around $6 billion in stock at roughly a $500 billion valuation. 4 Sam Altman jabbed at rival Elon Musk's Grok chatbot. REUTERS Altman said that he expects OpenAI to spend trillions of dollars on data center expansions. He has also expressed interest in buying Chrome if the US government forces Google to sell off the web browser as part of an antitrust case. Advertisement Separately, Altman confirmed reports that OpenAI is planning to launch a brain-computer interface startup similar to Elon Musk's Neuralink – and took a jab at his rival's firm xAI. 'You will definitely see some companies go make Japanese anime sex bots because they think that they've identified something here that works,' Altman said in a dig at Musk's Grok chatbot. 'You will not see us do that. We will continue to work hard at making a useful app, and we will try to let users use it the way they want, but not so much that people who have really fragile mental states get exploited accidentally.'
