Marvel at America’s green transition on your next vacation.
Scroll past San Jacinto Mountain, Brandini Toffee, a bicycle-powered bar crawl, and 13 other attractions on Tripadvisor’s list of “Things to Do in Palm Springs” and you’ll come to “Palm Springs Windmill Tours.” Its user-generated blurb tells would-be visitors to expect “a tour in the middle of wind turbine generators,” lest the name suggests something slightly more romantic and Dutch. In the accompanying photo, a black convertible noses toward the white gyrating towers that have become synonymous with the north entrance to the Coachella Valley.
If you leave your uncannily verdant gated community and drive up Highway 10 — away from the Mod Squad architectural tour and the horseback rides at Smoke Tree Stables, past signs advertising breast augmentations and the Air Force Reserve to homebound Angelenos — you’ll eventually reach a frontage road where a WINDMILL TOURS PARKING sign directs visitors toward an unassuming green trailer for check-in. All around the parking lot, and on both sides of the highway, you can already see the main attractions: wind turbines, many of them taller than the Statue of Liberty, though perspective is difficult here since there are hardly any normal-sized reference points, like palm trees, around for orientation.
One thing is immediately clear: This is “not Disneyland,” as Tom Spiglanin, Palm Springs Windmill Tours’ enthusiastic education director, will be the first to admit. “We’re not fun and games,” Spiglanin adds on a video call, about a week after I take a tour for myself. “Here, we are education.”
Once wind tour visitors have their curiosity piqued, “then we force the history down their throat, and it all turns out to be this great experience at the end,” says Tom Spiglanin.Heatmap/Jeva Lange
Visiting a wind farm on vacation admittedly might not be at the top of most people’s to-do lists. They still have a reputation as eye-sores: “Palm Springs, California, has been destroyed — absolutely destroyed — by the world’s ugliest wind farm at the Gateway on Interstate 10,” one future president tweeted in 2012. Even today, wind naysayers will leave fake one-star reviews that Spiglanin and his team have to dutifully remove.
But while it might not be much to look at from the parking lot, Palm Springs Windmill Tours sits at the intersection of two rich niches of the modern travel industry: eco-tourism and industrial tourism. The former is considered to be the fastest-growing segment within the global tourism industry; the latter is why I spent many a family car trip being shuttled to places like Grand Coulee Dam and Hoover Dam to marvel at the wonders of human engineering and hydroelectric power.
Though commercial wind farms are younger than Depression-era public works projects (Palm Spring’s just turned 40) and less scenic than a carbon-neutral eco-lodge in Costa Rica, they might have a place in the travel plans of the future: For one thing, as Spiglanin said, they’re educational. But they’re also an experience of history in real-time, almost like watching the Hoover Dam being built, something Palm Springs Windmill Tours impresses upon you with its first stop, an exhibit of obsolete and phased-out designs, the newest of which, the massive Zond Z-50, was removed from operation as recently as August 2022. Visiting a wind farm might still mostly be the dominion of nerds, but perhaps not for much longer; to tour one is to witness the unfolding story of America’s green transition.
The day I talk to Spiglanin, the wind is buffeting the tour trailer at 35 to 50 miles per hour — he shows me an app on his phone that caught one gust clocking in at 63 mph. April to June is windy season on the farm, when the phenomenon that makes the region so desirable for the renewable energy sector — hot air in the Valley rising, allowing cold air from the coast to funnel, with gusto, through San Gorgonio Pass — is at its most forceful. Across the highway from the trailer, a cluster of turbines have stopped turning, which sometimes happens to protect the machinery when the wind speeds are too high, though Spiglanin doesn’t think that’s the issue today. Maybe a circuit got shut off?
The Windmill Tours operate on Wintec Energy-owned land, but there is little communication between the tour company and the businesses that run the turbines, Spiglanin says. Though the tours initially began as a promotional arm of Wintec in the 1990s, intended to dispel negative local perceptions about the turbines, those ended after 9/11, when it seemed like it might not be such a good idea to have strangers tromping around on a piece of the local power grid. In 2014, Palm Springs Windmill Tours started anew as an LLC; though it’s still located on Wintec-owned land, its purposes are no longer strictly promotional — which is great for visitors, but leaves Spiglanin to wonder about things like why Brookfield Renewables, a Canadian power company that leases public land in the nearby hills, recently removed over 450 older turbines but hasn’t yet replaced them with its planned nine newer machines.
The tours are actually a bit of a joke among the techs who work on the turbines. “They laugh at the word ‘windmill’ because they're like, ‘dude, it’s not a windmill, it doesn’t have a grist stone,’” Spiglanin says. “And I'm like, ‘well, windmills don’t just have grist stones. They also pumped water, they started with grinding grain, but then—.’ And so we get into this whole thing, and it turns out I know a lot more about their business than they do.”
Spiglanin has a PhD in chemical physics and retired to the Coachella Valley after working as an educator at the Aerospace Corporation, in Los Angeles, for years. Driving past the windmills, he used to wonder if they had a tour; “lo and behold,” they did, and he ended up marrying the woman who ran their marketing. When it comes to wind, he’s thus a bit of a self-taught enthusiast, doing his own research for the exhibits and joining wind energy Facebook groups to geek out over, and glean more information about, the archival photos he uploads. He has also independently published a book of his research, Backstories of the Palm Springs Windmills, which is available in the gift shop along with stickers that read “I’m a big FAN of renewable energy.” (Wind nerds love puns; when I was checking in for my tour, I was asked what a turbine’s favorite music genre is. Heavy metal).

Recently, Palm Springs Windmill Tours learned they’re not the only land-based wind tour in the nation. Another wind farm in Washington State offers tours from a sparkling new visitor’s center that has vistas of the Cascades, as well as a hard-hat experience that allows visitors to actually look inside a turbine (in Palm Springs, guests have to stay 100 yards back from the operating machinery, something my dad, who was with me, eagerly pressed by counting out his strides). But the Washington tour is run by Puget Sound Energy, the regional energy supplier; Palm Springs Windmill Tours is uniquely independent and history-focused, taking what Spiglanin — with a nod to the Alcatraz Island tours — calls the National Park approach: “We have something here. We’re interpreting it. We’re helping people and our guests who come through here understand it.”
Other nations have also caught onto the draw wind farms have for visitors. In Scotland, England, and Denmark, wind farm tours have taken off with an added dash of adventure — boats bring visitors beneath the blades of offshore farms, while others offer mountain biking or hiking trails around the turbines. “While there’s no data to indicate the size of this nascent slice of the hospitality sector,” writes Bloomberg, “there is ample research to suggest that travelers are not only unfazed by wind farms, but find them objects of fascination.” As a boat captain who runs tours at a wind farm off of Rhode Island told the publication, “I thought, ‘This is definitely going to be a moneymaker.’”
It’s not necessarily a heightened interest in renewable energy, though, that is bringing visitors. Spiglanin says many of the guests who come to Palm Springs are actually interested in robotics. That is particularly true this year, since the world’s major high school robotics competition is focused this season on the future of sustainable energy and power: “As a result of that, we had a family fly down in a private jet from San Jose so that these kids could learn about wind energy, and they flew back the same day,” Spiglanin tells me.
Palm Springs Windmill Tours doesn’t mind shifting to fit the interests of its visitors, whether they’re engineers or curious passing travelers to whom “325 megawatts” — the storage capacity of an enormous new battery facility being built on the grounds — is just a number. The tour adapted to COVID-19 with a self-driving tour (the one I took, facilitated by an app) as well as an open-air golf cart tour. They’re bringing back bus tours this summer, too, both so tourists can stay air-conditioned as the temperatures begin to crest 100 degrees, but also because — as I increasingly realized speaking with Spiglanin — you can’t beat the experience of having a live, personal wind “fan” lead your way.
You won’t get views like you do from taking “the tram up to the top [of San Jacinto Mountain]” — the 8th-ranked attraction — “and we don’t give you good food. We actually don’t serve any food,” Spiglanin says. People still mostly come to Palm Springs for the music and the golf courses, the casinos and the Elvis honeymoon house, the sun and the stargazing. But maybe one day, they’ll come for the wind, too.

The multi-faceted investment is defense-oriented, but could also support domestic clean energy.
MP Materials is the national champion of American rare earths, and now the federal government is taking a stake.
The complex deal, announced Thursday, involves the federal government acting as a guaranteed purchaser of MP Materials’ output, a lender, and also an investor in the company. In addition, the Department of Defense agreed to a price floor for neodymium-praseodymium products of $110 per kilogram, about $50 above its current spot price.
MP Materials owns a rare earths mine and processing facility near the California-Nevada border on the edges of the Mojave National Preserve. It claims to be “the largest producer of rare earth materials in the Western Hemisphere,” with “the only rare earth mining and processing site of scale in North America.”
As part of the deal, the company will build a “10X Facility” to produce magnets, which the DOD has guaranteed will be able to sell 100% of its output to some combination of the Pentagon and commercial customers. The DOD is also kicking in $150 million worth of financing for MP Materials’ existing processing efforts in California, alongside $1 billion from Wall Street — specifically JPMorgan Chase and Goldman Sachs — for the new magnet facility. The company described the deal in total as “a multi-billion-dollar commitment to accelerate American rare earth supply chain independence.”
Finally, the DOD will buy $400 million worth of newly issued stock in MP Materials, giving it a stake in the future production that it’s also underwriting.
Between the equity investment, the lending, and the guaranteed purchasing, the Pentagon, and by extension the federal government, has taken on considerable financial risk in casting its lot with a company whose primary asset’s previous owner went bankrupt a decade ago. But at least so far, Wall Street is happy with the deal: MP Materials’ market capitalization soared to over $7 billion on Thursday after its share price jumped over 40%, from a market capitalization of around $5 billion on Wednesday and the company is valued at around $7.5 billion as of Friday afternoon.
Despite the risk, former Biden administration officials told me they would have loved to make a deal like this.
When I asked Alex Jacquez, who worked on industrial policy for the National Economic Council in the Biden White House, whether he wished he could’ve overseen something like the DOD deal with MP Materials, he replied, “100%.” I put the same question to Ashley Zumwalt-Forbes, a former Department of Energy official who is now an investor; she said, “Absolutely.”
Rare earths and critical minerals were of intense interest to the Biden administration because of their use in renewable energy and energy storage. Magnets made with neodymium-praseodymium oxide are used in the electric motors found in EVs and wind turbines, as well as for various applications in the defense industry.
MP Materials will likely have to continue to rely on both sets of customers. Building up a real domestic market for the China-dominated industry will likely require both sets of buyers. According to a Commerce Department report issued in 2022, “despite their importance to national security, defense demand for … magnets is only a small portion of overall demand and insufficient to support an economically viable domestic industry.”
The Biden administration previously awarded MP Materials $58.5 million in 2024 through the Inflation Reduction Act’s 48C Advanced Energy Project tax credit to support the construction of a magnet facility in Fort Worth. While the deal did not come with the price guarantees and advanced commitment to purchase the facility’s output of the new agreement, GM agreed to come on as an initial buyer.
Matt Sloustcher, an MP Materials spokesperson, confirmed to me that the Texas magnet facility is on track to be fully up and running by the end of this year, and that other electric vehicle manufacturers could be customers of the new facility announced on Thursday.
At the time MP Materials received that tax credit award, the federal government was putting immense resources behind electric vehicles, which bolstered the overall supply supply chain and specifically demand for components like magnets. That support is now being slashed, however, thanks to the One Big Beautiful Bill Act, which will cancel consumer-side subsidies for electric vehicle purchases.
While the Biden tax credit deal and the DOD investment have different emphases, they both follow on years of bipartisan support for MP Materials. In 2020, the DOD used its authority under the Defense Production Act to award almost $10 million to MP Materials to support its investments in mineral refining. At the time, the company had been ailing in part due to retaliatory tariffs from China, cutting off the main market for its rare earths. The company was shipping its mined product to China to be refined, processed, and then used as a component in manufacturing.
“Currently, the Company sells the vast majority of its rare earth concentrate to Shenghe Resources,” MP Materials the company said in its 2024 annual report, referring to a Chinese rare earths company.
The Biden administration continued and deepened the federal government’s relationship with MP Materials, this time complementing the defense investments with climate-related projects. In 2022, the DOD awarded a contract worth $35 million to MP Materials for its processing project in order to “enable integration of [heavy rare earth elements] products into DoD and civilian applications, ensuring downstream [heavy rare earth elements] industries have access to a reliable feedstock supplier.”
While the DOD deal does not mean MP Materials is abandoning its energy customers or focus, the company does appear to be to the new political environment. In its February earnings release, the company mentioned “automaker” or “automotive-grade magnets” four times; in its May earnings release, that fell to zero times.
Former Biden administration officials who worked on critical minerals and energy policy are still impressed.
The deal is “a big win for the U.S. rare earths supply chain and an extremely sophisticated public-private structure giving not just capital, but strategic certainty. All the right levers are here: equity, debt, price floor, and offtake. A full-stack solution to scale a startup facility against a monopoly,” Zumwalt-Forbes, the former Department of Energy official, wrote on LinkedIn.
While the U.S. has plentiful access to rare earths in the ground, Zumwalt-Forbes told me, it has “a very underdeveloped ability to take that concentrate away from mine sites and make useful materials out of them. What this deal does is it effectively bridges that gap.”
The issue with developing that “midstream” industry, Jacquez told me, is that China’s world-leading mining, processing, and refining capacity allows it to essentially crash the price of rare earths to see off foreign competitors and make future investment in non-Chinese mining or processing unprofitable. While rare earths are valuable strategically, China’s whip hand over the market makes them less financially valuable and deters investment.
“When they see a threat — and MP is a good example — they start ramping up production,” he said. Jacquez pointed to neodymium prices spiking in early 2022, right around when the Pentagon threw itself behind MP Materials’ processing efforts. At almost exactly the same time, several state-owned Chinese rare earth companies merged. Neodymium-praseodymium oxide prices fell throughout 2022 thanks to higher Chinese production quotas — and continued to fall for several years.
While the U.S. has plentiful access to rare earths in the ground, Zumwalt-Forbes told me, it has “a very underdeveloped ability to take that concentrate out away from mine sites and make useful materials out of them. What this deal does is it effectively bridges that gap.”
The combination of whipsawing prices and monopolistic Chinese capacity to process and refine rare earths makes the U.S.’s existing large rare earth reserves less commercially viable.
“In order to compete against that monopoly, the government needed to be fairly heavy handed in structuring a deal that would both get a magnet facility up and running and ensure that that magnet facility stays in operation and weathers the storm of Chinese price manipulation,” Zumwalt-Forbes said.
Beyond simply throwing money around, the federal government can also make long-term commitments that private companies and investors may not be willing or able to make.
“What this Department of Defense deal did is, yes, it provided much-needed cash. But it also gave them strategic certainty around getting that facility off the ground, which is almost more important,” Zumwalt-Forbes said.
“I think this won’t be the last creative critical mineral deal that we see coming out of the Department of Defense,” Zumwalt-Forbes added. They certainly are in pole position here, as opposed to the other agencies and prior administrations.”
On a new plan for an old site, tariffs on Canada, and the Grain Belt Express
Current conditions: Phoenix will “cool” to 108 degrees Fahrenheit today after hitting 118 degrees on Thursday, its hottest day of the year so far • An extreme wildfire warning is in place through the weekend in Scotland • University of Colorado forecasters decreased their outlook for the 2025 hurricane season to 16 named storms, eight hurricanes, and three major hurricanes after a quiet June and July.
President Trump threatened a 35% tariff on Canadian imports on Thursday, giving Prime Minister Mark Carney a deadline of August 1 before the levies would go into effect. The move follows months of on-again, off-again threats against Canada, with former Canadian Prime Minister Justin Trudeau having successfully staved off the tariffs during talks in February. Despite those earlier negotiations, Trump held firm on his 50% tariff on steel and aluminum, which will have significant implications for green manufacturing.
As my colleagues Matthew Zeitlin and Robinson Meyer have written, tariffs on Canadian imports will affect the flow of oil, minerals, and lumber, as well as possibly break automobile supply chains in the United States. It was unclear as of Thursday, however, whether Trump’s tariffs “would affect all Canadian goods, or if he would follow through,” The New York Times reports. The move follows Trump’s announcement this week of tariffs on several other significant trade partners like Japan and South Korea, as well as a 50% tariff on copper.
The long beleaguered Lava Ridge Wind Project, formally halted earlier this year by an executive order from President Trump, might have a second life as the site for small modular reactors, Idaho News 6 reports. Sawtooth Energy Development Corporation has proposed installing six small nuclear power generators on the former Lava Ridge grounds in Jerome County, Idaho, drawn to the site by the power transmission infrastructure that could connect the region to the Midpoint Substation and onto the rest of the Western U.S. The proposed SMR project would be significantly smaller in scale than Lava Ridge, which would have produced 1,000 megawatts of electricity on a 200,000-acre footprint, sitting instead on 40 acres and generating 462 megawatts, enough to power 400,000 homes.
Sawtooth Energy plans to hold four public meetings on the proposal beginning July 21. The Lava Ridge Wind Project had faced strong local opposition — we named it the No. 1 most at-risk project of the energy transition last fall — due in part to concerns about the visibility of the turbines from the Minidoka National Historic Site, the site of a Japanese internment camp.

Republican Senator Josh Hawley of Missouri said on social media Thursday that Energy Secretary Chris Wright had assured him that he will be “putting a stop to the Grain Belt Express green scam.” The Grain Belt Express is an 804-mile-long, $11 billion planned transmission line that would connect wind farms in Kansas to energy consumers in Missouri, Illinois, and Indiana, which has been nearing construction after “more than a decade of delays,” The New York Times reports. But earlier this month, Missouri Attorney General Andrew Bailey, a Republican, put in a request for the local public service commission to reconsider its approval, claiming that the project had overstated the number of jobs it would create and the cost savings for customers. Hawley has also been a vocal critic of the project and had asked the Energy Department to cancel its conditional loan guarantee for the transmission project.
New electric vehicles sold in Europe are significantly more environmentally friendly than gas cars, even when battery production is taken into consideration, according to a new study by the International Council on Clean Transportation. Per the report, EVs produce 73% less life-cycle greenhouse gas emissions than combustion engine cars, even considering production — a 24% improvement over 2021 estimates. The gains are also owed to the large share of renewable energy sources in Europe, and factor in that “cars sold today typically remain on the road for about 20 years, [and] continued improvement of the electricity mix will only widen the climate benefits of battery electric cars.” The gains are exclusive to battery electric cars, however; “other powertrains, including hybrids and plug-in hybrids, show only marginal or no progress in reducing their climate impacts,” the report found.

With the United Kingdom staring down its third heatwave in a month this week, a new study warns of dire consequences if homes and cities do not adapt to the new climate reality. According to researchers at the University College London and the London School of Hygiene and Tropical Medicine, heat-related deaths in England and Wales could rise 50-fold by the 2070s, jumping from a baseline of 634 deaths to 34,027 in a worst-case scenario of 4.3 degrees Celsius warming, a high-emissions pathway.
The report specifically cited the aging populations of England and Wales, as older people become more vulnerable to the impacts of extreme heat. Low adoption of air conditioning is also a factor: only 2% to 5% of English households use air conditioning, although that number may grow to 32% by 2050. “We can mitigate [the] severity” of the health impacts of heat “by reducing greenhouse gas emissions and with carefully planned adaptations, but we have to start now,” UCL researcher Clare Heaviside told Sky News.
This week, Centerville, Ohio, rolled out high-tech recycling trucks that will use AI to scan the contents of residents’ bins and flag when items have been improperly sorted. “Reducing contamination in our recycling system lowers processing costs and improves the overall efficiency of our collection,” City Manager Wayne Davis said in a statement about the AI pilot program, per the Dayton Daily News.
Or at least the team at Emerald AI is going to try.
Everyone’s worried about the ravenous energy needs of AI data centers, which the International Energy Agency projects will help catalyze nearly 4% growth in global electricity demand this year and next, hitting the U.S. power sector particularly hard. On Monday, the Department of Energy released a report adding fuel to that fire, warning that blackouts in the U.S. could become 100 times more common by 2030 in large part due to data centers for AI.
The report stirred controversy among clean energy advocates, who cast doubt on that topline number and thus the paper’s justification for a significant fossil fuel buildout. But no matter how the AI revolution is powered, there’s widespread agreement that it’s going to require major infrastructure development of some form or another.
Not so fast, says Emerald AI, which emerged from stealth last week with $24.5 million in seed funding led by Radical Ventures along with a slew of other big name backers, including Nvidia’s venture arm as well as former Secretary of State John Kerry, Google’s chief scientist Jeff Dean, and Kleiner Perkins chair John Doerr. The startup, founded and led by Orsted’s former chief strategy and innovation officer Varun Sivaram, was built to turn data centers from “grid liabilities into flexible assets” by slowing, pausing, or redirecting AI workloads during times of peak energy demand.
Research shows this type of data center load flexibility could unleash nearly 100 gigawatts of grid capacity — the equivalent of four or five Project Stargates and enough to power about 83 million U.S. homes for a year. Such adjustments, Sivaram told me, would be necessary for only about 0.5% of a data center’s total operating time, a fragment so tiny that he says it renders any resulting training or operating performance dips for AI models essentially negligible.
As impressive as that hypothetical potential is, whether a software product can actually reduce the pressures facing the grid is a high stakes question. The U.S. urgently needs enough energy to serve that data center growth, both to ensure its economic competitiveness and to keep electricity bills affordable for Americans. If an algorithm could help alleviate even some of the urgency of an unprecedented buildout of power plants and transmission infrastructure, well, that’d be a big deal.
While Emerald AI will by no means negate the need to expand and upgrade our energy system, Sivaram told me, the software alone “materially changes the build out needs to meet massive demand expansion,” he said. “It unleashes energy abundance using our existing system.”
Grand as that sounds, the fundamental idea is nothing new. It’s the same concept as a virtual power plant, which coordinates distributed energy resources such as rooftop solar panels, smart thermostats, and electric vehicles to ramp energy supply either up or down in accordance with the grid’s needs.
Adoption of VPPs has lagged far behind their technical potential, however. That’s due to a whole host of policy, regulatory, and market barriers such as a lack of state and utility-level rules around payment structures, insufficient participation incentives for customers and utilities, and limited access to wholesale electricity markets. These programs also depend on widespread customer opt-in to make a real impact on the grid.
“It’s really hard to aggregate enough Nest thermostats to make any kind of dent,”” Sivaram told me. Data centers are different, he said, simply because “they’re enormous, they’re a small city.” They’re also, by nature, virtually controllable and often already interconnected if they’re owned by the same company. Sivaram thinks the potential of flexible data center loads is so promising and the assets themselves so valuable that governments and utilities will opt to organize “bespoke arrangements for data centers to provide their services.”
Sivaram told me he’s also optimistic that utilities will offer data center operators with flexible loads the option to skip the ever-growing interconnection queue, helping hyperscalers get online and turn a profit more quickly.
The potential to jump the queue is not something that utilities have formally advertised as an option, however, although there appears to be growing interest in the idea. An incentive like this will be core to making Emerald AI’s business case work, transmission advocate and president of Grid Strategies Rob Gramlich told me.
Data center developers are spending billions every year on the semiconductor chips powering their AI models, so the typical demand response value proposition — earn a small sum by turning off appliances when the grid is strained — doesn’t apply here. “There’s just not anywhere near enough money in that for a hyperscaler to say, Oh yeah, I’m gonna not run my Nvidia chips for a while to make $200 a megawatt hour. That’s peanuts compared to the bazillions [they] just spent,” Gramlich explained.
For Emerald AI to make a real dent in energy supply and blunt the need for an immediate and enormous grid buildout, a significant number of data center operators will have to adopt the platform. That’s where the partnership with Nvidia comes in handy, Sivaram told me, as the startup is “working with them on the reference architecture” for future AI data centers. “The goal is for all [data centers] to be potentially flexible in the future because there will be a standard reference design,” Sivaram said.
Whether or not data centers will go all in on Nvidia’s design remains to be seen, of course. Hyperscalers have not typically thought of data centers as a flexible asset. Right now, Gramlich said, most are still in the mindset that they need to be operating all 8,760 hours of the year to reach their performance targets.
“Two or three years ago, when we first noticed the surge in AI-driven demand, I talked to every hyperscaler about how flexible they thought they could be, because it seemed intuitive that machine learning might be more flexible than search and streaming,” Gramlich told me. By and large, the response was that while these companies might be interested in exploring flexibility “potentially, maybe, someday,” they were mostly focused on their mandate to get huge amounts of gigawatts online, with little time to explore new data center models.
“Even the ones that are talking about flexibility now, in terms of what they’re actually doing in the market today, they all are demanding 8,760 [hours of operation per year],” Gramlich told me.
Emerald AI is well aware that its business depends on proving to hyperscalers that a degree of flexibility won’t materially impact their operations. Last week, the startup released the results of a pilot demonstration that it ran at an Oracle data center in Phoenix, which proved it was able to reduce power consumption by 25% for three hours during a period of grid stress while still “assuring acceptable customer performance for AI workloads.”
It achieved this by categorizing specific AI tasks — think everything from model training and fine tuning to conversations with chatbots — from high to low priority, indicating the degree to which operations could be slowed while still meeting Oracle’s performance targets. Now, Emerald AI is planning additional, larger-scale demonstrations to showcase its capacity to handle more complex scenarios, such as responding to unexpected grid emergencies.
As transmission planners and hyperscalers alike wait to see more proof validating Emerald AI’s vision of the future, Sivaram is careful to note that his company is not advocating for a halt to energy system expansion. In an increasingly electrified economy, expanding and upgrading the grid will be essential — even if every data center in the world has a flexible load profile.
’We should be building a nationwide transmission system. We should be building out generation. We should be doing grid modernization with grid enhancing technologies,” Sivaram told me. “We just don’t need to overdo it. We don’t need the particularly massive projections that you’re seeing that are going to cause your grandmother’s electricity rates to spike. We can avoid that.”
