President Donald Trump and members of his cabinet highlighted the surging demand for energy that will be needed to power the growth in artificial intelligence (AI) at an event this week in Pennsylvania.
Pennsylvania Republican Senator Dave McCormick organized an AI and energy summit Tuesday at Carnegie Mellon University in Pittsburgh, where he and other political and business leaders framed the race to develop AI as crucial to economic and national security interests.
"This is a competition we must win," McCormick said in opening remarks at the event.
Billionaire businessman Jonathan Gray, president and CEO of the asset management firm Blackstone Group, said in a panel discussion at the event that access to energy has emerged as the main constraint on AI.

"Energy is the limiting factor," Gray said. "Unless we get the energy side right, we can't do this."
Energy analysts predict a coming spike in electricity demand for energy-hungry data centers. A Department of Energy report in December predicted that electricity use by data centers in the U.S. could nearly triple over the coming three years, consuming as much as 12 percent of the country's total electricity output by 2028.
Tech companies are racing to secure connections to the electric grid, pouring money into new energy sources and, in some cases, securing their own power supplies. Grid managers, utility companies and regulators, meanwhile, are wrestling with how to meet the growing demand while keeping the power supply affordable and reliable.
Sustainability is also at risk as the AI boom drives up greenhouse gas emissions, knocking many tech companies off target for their net-zero climate goals.
Against this fraught backdrop, one emerging technology seeks to make AI data centers friendlier users of the power grid.
"Our goal is to make these data centers flexible in their power consumption," Varun Sivaram, CEO and founder of Emerald AI, told Newsweek.
Emerald made waves this month when it announced a $24.5 million round of financing backed by big names connecting the tech, energy and climate worlds, including chip maker Nvidia, former climate envoy John Kerry and Kleiner Perkins chair John Doerr.
Sivaram explained that Emerald's platform allows grid managers to remotely shift power demand for data centers without affecting AI performance.
"That makes it possible to connect far more data centers to today's energy system and more efficiently use today's energy system without a massive build-out of new infrastructure," he said.
Utility companies and grid managers must plan for peak energy demand—those times when electricity use will be highest across the service area—and build electricity generation capacity to match those peak moments.
Often, some of the most expensive and most polluting sources in a regional power fleet are "peaker plants," the ones that turn on only at times of peak demand. But if those power companies could better anticipate and control the demand for electricity, they might avoid the need for those extra peak power supplies and reduce the risk of blackouts.
Sivaram said Emerald applies that concept of demand-side management to the special properties of data centers, giving power system managers more flexibility.
"They don't have to assume that a 200- or 500-megawatt data center is going to ask for its full allocation at that exact, worst moment when everybody's running their air conditioning on a hot summer day," he said.
Emerald and some partner companies put the technology to a test recently in Phoenix, a place with a high concentration of data centers and a pressing need for air conditioning.
"I think it was like 96 degrees that day," he said. "Everyone was using their air conditioning."
When the local power provider alerted Emerald that peak energy demand was approaching, the company put its platform into action, reducing power consumption by AI chip clusters by 25 percent while the rest of the city needed the most energy.
"We held that lower period of power consumption for three hours, during which time the power peaked and started coming back down," Sivaram said.
Sivaram said he thinks this approach has the potential to flip the script on the AI energy issue, turning data centers into "grid allies" instead of a potential threat.
"Communities are afraid their rates will go up, their power grid will crash, and these data centers will use diesel generators, which are dirty and create air pollution," he said. "Emerald AI's approach to flexibility mitigates all three of these."
Newsweek will dive further into the issues around data center energy demand during an all-day event in September during Climate Week NYC. Mark your calendar for "Powering Ahead" on Thursday, September 25.

Fact Check: Photo showing Trump and Epstein with a minor girl isn't what it seems
Claim: An image authentically shows Jeffrey Epstein posing with U.S. President Donald Trump and a young girl. Rating: An image claiming to show a young girl with U.S. President Donald Trump and the late sex offender Jeffrey Epstein has repeatedly circulated online, reappearing once more in early and mid-July 2025. The image resurfaced with renewed attention after the U.S. Department of Justice released a memo on July 7, 2025, stating that it found no incriminating "client list" and no credible evidence Epstein had blackmailed prominent people. The department's review also concluded "no further disclosure would be appropriate or warranted" in its investigation of Epstein. The next day, Trump responded to a reporter's question at a Cabinet meeting by saying, "Are you still talking about Jeffrey Epstein? This guy's been talked about for years." One July 9, 2025, X post (archived) with the image referred to Attorney General Pam Bondi — who leads the DOJ — in its caption: "Hey Magas! This is what Barbie Bondi is protecting! If this doesn't make you angry you're part of the problem! 🤬." (X user @koolkaryn) The image has appeared over the years on multiple social media platforms, including Instagram and Reddit, as well as Chinese-language websites. In short, we found the image contained numerous signs it was generated using artificial intelligence. For instance, the girl's left hand seemed to be deformed, along with the left sleeve of Trump's jacket. (X user @FlyingDutchPall) Via a reverse-image search, we found a full-size version of the viral image shared on Quora. (TheGoodRussian Quora profile) In the original version of the image we spotted more indications the photograph was created artificially. For instance, the faces of people in the background were deformed, Trump had only one leg and Epstein seemed to be dissolving into the couch. (TheGoodRussian Quora profile) Given that the in-question photograph was created using AI software, we have rated it as fake. We've fact-checked other Epstein- and Trump-related claims, including debunking a supposed photo of the men on a plane. In July 2023, we investigated another AI-generated image, allegedly showing Trump and Epstein posing with underage girls. That said, some viral photos of the pair together are genuine. Take this 1997 photograph, for instance, that was taken at Trump's Mar-a-Lago estate in Palm Beach, Florida. Baum, Sarah. "Does This Photo Show Trump and Epstein with Underage Girls?"

Powell is costing the US by not lowering rates, says Trump. Here's what he may mean
Source: CNN As part of his campaign to get rid of Jerome Powell, President Donald Trump has blamed the Federal Reserve chair for costing the country 'hundreds of billions of dollars' by not slashing interest rates. 'You have cost the USA a fortune and continue to do so,' Trump wrote in a handwritten note to Powell that he posted on Truth Social last month. 'You should lower that rate by a lot. Hundreds of billions of dollars are being lost.' In the same post, Trump blamed the Fed board, saying, 'If they were doing their job properly, our Country would be saving Trillions of Dollars in Interest Cost … We should be paying 1% Interest, or better!' Trump's focus on interest costs comes at a time of renewed attention on the nation's skyrocketing interest payments on its ever-growing federal debt. Interest payments this fiscal year are nearing $1 trillion for the first time in the nation's history. The president just signed the 'big, beautiful bill,' which is expected to add more than $3 trillion to the deficit over the next decade and push interest rates even higher. And Moody's recently downgraded the US debt in part because of the increase in government debt and interest payment ratios. But even if Trump succeeds in pressuring the Fed to reduce rates, it may not significantly lighten the nation's interest payment burden, experts said. The federal funds rate is only one of the factors that influences the interest rates on the federal debt, which is made up of a mix of short-term, medium-length and longer-duration Treasury securities. 'It seems to be an easier lever to pull for those who want to impact either interest costs on the federal debt or economic growth,' said Shai Akabas, vice president of economic policy at the Bipartisan Policy Center. 'But it doesn't mean that action by the Fed will result in the outcome the president or others may want.' What's indisputable is that America's interest costs have soared in recent years, in part because of the nation's growing debt and in part because interest rates rose after a period of super-low rates as the nation combatted high inflation earlier in the decade. The US shelled out $346 billion in interest payments in fiscal 2020. That figure has jumped to a projected $952 billion for the current fiscal year and is expected to exceed $1 trillion in the coming year, according to the Congressional Budget Office. Interest payments are now the second-largest spending category in the federal budget, surpassing Medicare and defense in fiscal year 2024 and trailing only Social Security. Currently, roughly 18 cents of every dollar in tax revenue goes to paying interest on the debt, Akabas said. By the end of the next decade, that figure will jump to about 25 cents. While cutting the federal funds rate may lower rates on shorter-term securities, it may not reduce rates on 10-year or 30-year Treasury bonds. In fact, a sharp cut may increase longer-term rates for several reasons, including that a steep rate cut could spur inflation or could prompt investors to shift to longer-term securities to lock in higher rates, said Marc Goldwein, senior policy director at the Committee for a Responsible Federal Budget. 'The Federal Reserve only has so much power to lower those interest rates,' he said of the rates on longer duration Treasury bonds. 'There's no guarantee that the Fed cutting rates will reduce interest payments at all.' If Trump were truly interested in reducing interest payments, there is a more efficient way to do that, experts said. He could work to lower the annual deficit — though that would likely involve some politically unpalatable changes to taxes and spending, they said. While Trump's agenda package will make historic reductions to federal spending on the nation's safety net, its hefty tax cuts far surpass the savings and widen the annual deficit. 'If your concern is the hundreds of billions of dollars we're adding to the deficit from higher interest costs, the solution is to enact policies that are deficit reducing, not deficit increasing' Goldwein said.
