Where climate hawks meet China hawks.

Why are relations between China and the United States deteriorating? Why does the global outlook feel like it’s darkening? A few weeks ago, Brian Deese, President Biden’s former top economic aide, offered a theory on Shift Key, the podcast I cohost with Princeton engineering professor Jesse Jenkins.
We started by asking Deese whether the U.S. should import the cheap electric cars that Chinese companies are beginning to churn out by the millions.
He began by politely disputing the premise of our question. It was wrong to assume, he said, that China is a “market-based economy and a market-based actor.” It would even be wrong to assume we’re in “a balanced and sustainable global trading” system.
He continued:
In terms of the global trading system, we have this enormous imbalance because China has this enormous excess savings. And what they’re trying to do to try to solve the acute economic challenges that they face is to plow that into manufacturing with the explicit goal of trying to dominate — not just try to gain competitive edge, but dominate particular industries. And when they do that … they flood markets with cheap goods.
These “excess savings” impose their own burden on the United States, he said, so we can’t just accept the cheaper consumer goods and move on. “We, the recipient countries, end up paying a lot of the cost of those Chinese subsidies and those Chinese policies,” Deese said. “We end up paying by our own industries, our own capabilities being diminished and derogated in a way that they wouldn’t have that imbalance not existed.”
If these ideas seem to you to be coming out of nowhere, you are probably not alone. What could Chinese financial savings have to do with the success of its EV industry? But for people who have followed left-ish-wing arguments about trade and geopolitics over the past few years, what Deese is saying is immediately familiar. He is glossing a set of ideas argued most famously by the 2020 book Trade Wars Are Class Wars, by the finance professor Michael Pettis and the financial journalist Matthew C. Klein.
These ideas are widely understood in the world of heterodox economists who resist neoclassical approaches to the field but have received little airing in the broader press. Yet they are increasingly important to understanding how the Biden administration sees the world. As Dylan Matthews of Vox has noted, the Biden administration can sometimes seem like a perplexing alliance of left-wing economic thinkers and China hawks. The Klein-Pettis book is the intellectual mortar fusing those two camps.
The book’s argument is nuanced and wide-ranging, but here is a brief summary. The global economy, Klein and Pettis argue, suffers from a destabilizing and dangerous imbalance, which, if left unchecked, could spiral into a global war. The cause of this imbalance is that since 1991, a handful of countries — notably China and Germany — have passed policies that depress their workers’ wages. These actions have included higher taxes, welfare cuts, lower environmental standards, and sometimes open graft, but they all achieve the same end: They impose great costs on the working class, artificially suppressing citizens’ income and reducing their quality of life, to the benefit of each country’s industrial leaders.
This, the “class war” of the book’s title, has rippled across the global economy in several ways. It has, first, allowed China and some European countries to build up a disproportionately large share of the world’s manufacturing industries. Since workers there are paid so much less than they would be elsewhere, companies are happy to relocate their factories to profit from cheap costs and (in China) low environmental standards. But because Chinese and German workers are systematically underpaid, they cannot afford what they are producing, thus forcing other countries to buy their artificially cheap finished goods. These are the titular “trade wars.”
This is not the end of the story. According to Klein and Pettis, China’s “class war” policies — such as its hukou system, which has created a roving migrant class within the country who lack access to welfare benefits — has artificially enriched its wealthy elite. These industrialists, executives, and officials cannot spend their money as fast as they earn it, meaning that they must save it. Specifically, they seek to save it in U.S. dollars, the world’s reserve currency, snapping up dollar-denominated bonds, stocks, and mortgages. This, in turn, drives up asset prices and generates artificial credit bubbles in the United States and its ally countries, as the world’s extra cash seeks a productive outlet somewhere in the American economy. And because global demand for U.S. financial products pushes up the cost of a U.S. dollar, it makes any goods produced in America more expensive, which further dings the competitiveness of American manufacturers versus their Chinese or German peers.
In short, over the past few decades, “the world’s rich were able to benefit at the expense of the world’s workers and retirees because the interests of American financiers were complementary to the interests of Chinese and German industrialists,” Klein and Pettis write. But note that there is a destabilizing cyclical mechanic to this story too: As China takes more global manufacturing, its excess savings build up further, which slosh around the global economy and generate larger and larger credit bubbles.
This is what Deese was referring to when he condemned China’s “enormous excess savings,” and this is why he identifies those savings as a key driver of China’s manufacturing boom. In the Klein-Pettis worldview, the underlying cause of the destructive tendency in the global economy is the way that its economy systematically steals from the poor and enriches the wealthy. As Deese told us:
China needs to decide if it loves this unsustainable, unbalanced, in many cases, illegal manufacturing strategy more than it hates the kind of domestic reforms it would actually need to take to boost domestic consumption, produce more balanced growth as it becomes a more mature economy.
This intellectual strain has long been present in the Biden administration’s thinking, but recently it has taken on a new prominence. On Wednesday, Treasury Secretary Janet Yellen warned China against flooding global markets with cheap green technology exports while speaking at a Georgia solar factory. “China’s overcapacity distorts global prices and production patterns and hurts American firms and workers, as well as firms and workers around the world,” she said.
Biden himself has even begun to sound this note. You can see the soft influence of Trade Wars thinking in his promise that Chinese electric vehicles will not overwhelm American automakers. “China is determined to dominate the future of the auto market, including by using unfair practices,” he said in a statement last month. “I’m not going to let that happen on my watch.”
For Klein and Pettis, and presumably for the Biden administration, these “unfair practices” can be relieved only by China allowing the consumption share of its economy to rise. They argue that China must stop plowing money into unsustainable investment projects and instead allow its economy to be piloted by consumers, not party officials.
That this would require revising the country’s political system, which concentrates power in the hands of the economic elite, is what makes it so unlikely. On the other hand, if China fails to reform its system, then the consequences could be even more painful: Klein and Pettis suggest that a similar dynamic among the late-19th century Great Powers led to World War I.
Ultimately, Trade Wars Are Class Wars does not predict what will happen. The authors are clear that America’s and China’s economic growth are not necessarily in conflict; only the current dynamic makes it seem so. But the book also suggests a few ideas that it does not fully articulate — presumably because Pettis, who is a professor at Peking University, lives in Beijing.
The biggest of these is that China’s political economy could metastasize into far more malign forms than it holds today. If you think about a country’s politics and economy as necessarily growing and changing together — its politics taking a form that its economics can tolerate, and vice versa — then China’s politics and economy are not necessarily destined to grow along a consumer-friendly path. Today, China produces more solar panels and electric cars than it can consume, and it must find a way to get rid of them. But there are other lines of business — and political styles — that have a demonically self-disposing tendency.

Current conditions: France just recorded its hottest day ever, with Wednesday’s temperatures soaring to just under 111 degrees Fahrenheit; nearly 50 people died drowning while seeking respite from the heat • A pair of 7.1-magnitude earthquakes struck Venezuela, collapsing buildings in Caracas • Wind has whipped the Cottonwood Fire, one of six wildfires raging in Utah, into a larger blaze now covering 60,000 acres — and it’s still at 0% containment.
New Jersey Representative Frank Pallone, the ranking Democrat on the House Energy and Commerce committee, joined calls for a national moratorium on data center construction ahead of Wednesday afternoon’s markup of a series of bills related to the buildout of infrastructure to support artificial intelligence software. In a statement, Pallone described the bills as a “useful first step,” but one that, “compared to the challenges the American power grid is facing,” amounts to “not nearly enough.” Rather, he backed a “national AI data center moratorium until we can find a way to ensure they don’t harm our nation’s air, water, and power bills.” Pallone’s new public position makes him one of the highest-ranking Democrats yet to back the idea, championed by the likes of Representative Alexandria Ocasio-Cortez, of halting permitting on new data centers in response to the growing blowback from voters.
Pallone’s shift comes in response to the Ratepayer Protection Act, which would enshrine into law the voluntary pledge tech companies signed with the White House to pay for grid costs from their server farms. Heatmap’s Matthew Zeitlin wrote earlier this week that the bill was “not so much an anti-artificial intelligence or anti-data center bill, but rather a move to insulate further data center development from political pressure stemming from rising electricity costs.” When Pallone made his statement a day later, Matthew wrote: “Well, at least one influential lawmaker seems to agree with me.”
The Iran War has cost the average American car owner an extra $156 and the average SUV driver another $232 in gasoline costs, according to new data from the policy shop Third Way. But the newly mapped analysis, shared exclusively with me, shows that Republican-leaning states in the Mountain West and beyond paid some of the highest prices for a conflict. Alaska saw one of the biggest spikes, with gas prices rising by $1.40 per gallon, a 39% increase. Wyoming followed close behind, with prices soaring by $1.37 per gallon, a 50% surge. Prices in Utah, meanwhile, climbed by $1.30, or 47%. That stands in contrast to many big Democratic-leaning states. New York’s gas prices rose by $1.23, or 41%, while California’s prices went up $0.94, or 20%. That, of course, doesn’t reflect where the prices were already high. I just returned this week from a trip to Los Angeles, where gas was nearly twice as expensive as in New York City.
Century Aluminum, America’s largest primary aluminum producer and the developer behind the first new U.S. smelter in 50 years, has inked a deal with a green cement startup to supply a key raw material. Brimstone, known as a major player in the race to commercialize green cement, also generates alumina. On Wednesday, the startup unveiled a memorandum of understanding with Century Aluminum to establish a domestic “mine to metal supply chain” for aluminum made from scratch rather than scrap. “Foreign sources, including China, currently dominate global alumina production. Brimstone is bringing alumina production home and doing it at a globally competitive price,” Brimstone CEO Cody Finke said in a press release. “Brimstone is upending the massive global imbalance by producing alumina from rock quarried here in the United States.”

Until the nation’s flagship reactor project came online and transformed Southern Company’s Alvin W. Vogtle Generating Station in eastern Georgia into America’s most powerful atomic electrical plant, Arizona’s Palo Verde Generating Station was the No.1 nuclear facility by size in the country. The desert state is now looking to reclaim its mantle. The trio of utilities Arizona Public Service, Salt River Project, and Tucson Electric Power said Wednesday they are continuing “to work together to explore adding nuclear generation in Arizona.” The next step, the companies said, is a siting study that’s expected to be completed within the next six months. The Arizona Corporation Commission, the regulator in charge of utilities in the state, is holding an informational workshop today.
Meanwhile, the developer behind Canada’s flagship reactor design — which, because it’s cooled with pressurized heavy water, can run on raw uranium — just submitted initial paperwork to the Nuclear Regulatory Commission to start the licensing process to approve what’s known as the CANDU. Pronounced CAN-do and produced by manufacturer AtkinsRéalis, the reactor is the workhorse of the Canadian and Indian fleets and can be built reliably, but requires more maintenance than the light water reactors that run on enriched uranium and make up the entire U.S. fleet. “As the United States enters a new chapter in its civilian nuclear program, AtkinsRéalis is uniquely positioned, as the steward of CANDU technology, to help advance the country’s ambitious energy policy through proven, low-cost reactor technology with a world-class reputation,” Ian L. Edwards, the company’s president and chief executive, said in a statement. As I told you last month, the CANDU is at the heart of Canada’s new nuclear strategy.

The world needs a lot more copper. And while siting and building new mines takes time, two of the planet’s biggest producers are preparing to increase production at existing mines. On Wednesday, London-based Anglo American and the Chilean state-owned Codelco inked a deal to increase production through a joint venture at Los Bronces and Andina copper mines in the South American nation. The joint mining plan is expected to unlock 2.7 million metric tons of additional copper over a 21-year period, delivering an average of 12,000 tons per year. The increase comes with “minimal capital investment” and should bring the new supply online by 2030. “This agreement represents a more efficient and responsible way to develop one of the world’s leading copper districts,” Bernardo Fontaine, Codelco’s chairman, said in a statement. “It allows us to make better use of existing infrastructure, capture greater benefits for Chile, and move forward with a long-term vision based on operational excellence, sustainability, and the responsible use of resources.”
If green hydrogen is the stuff made with clean electricity and water and blue hydrogen is made with natural gas equipped with carbon capture, then the orange stuff is found in underground rock formations where naturally occurring gas forms and then is encouraged to continue forming through artificial means. Heatmap’s Katie Brigham did a good job of explaining the concept here. Well, now a French renewables developer FDE is promising to start producing orange hydrogen “by late 2028 or early 2029” after finding a naturally-occurring underground reservoir in northern France that can be tapped and stimulated to produce additional fuel, Hydrogen Insight reported.
How China saved the world from $200 oil.
Turn your mind back to early March, soon after Iran announced that it was closing the Strait of Hormuz. Energy experts told us to expect calamity.
Roughly 20% of the world’s oil and liquified natural gas supply moved through the narrow waterway, they said, and we would not soon be able to replace it. Oil prices would rocket to $150 or $200 a barrel. The world faced the worst energy supply shock in history.
We braced ourselves. We waited. And then … it didn’t happen.
Sure, the global oil benchmark rose to about $115 a barrel. Energy prices increased everywhere, and Southeast Asia faced a real crunch. But the worst consequences never hit. Europe didn’t run out of jet fuel, we didn’t get $8 gas across the United States, and the global economy did not shut down. Why?
We can now say with confidence: China bailed us out (and itself out, too). Without fanfare, the country slashed its energy imports and conducted a massive release from its strategic stockpiles of crude oil and liquid fuels. It eliminated something like 5 million daily barrels of oil demand, or about 5% of global oil demand.
Although it might seem technical, the implications of that silent intervention are huge for geopolitics, climate policy, and the future of the oil market. That’s why it’s the topic of today’s episode of Shift Key, Heatmap’s podcast. I encourage you to listen to my conversation with oil analyst Rory Johnston as he walks me through the wonky details — how we know China did this (math and satellite imagery), whether it has a modern precedent (it doesn’t), and what it all means (potentially a lot). He calls this public discovery of China’s latent power “the most important thing” we learned from the Iran war.
Anyway, I won’t ruin the conversation. (You can listen to Shift Key for free on any podcast platform, by the way.) But I do want to mull some of the implications here. The most important, to my mind, has to do with market power.

In oil markets, we often talk about “swing producers.” Saudi Arabia and other OPEC+ countries can shift the global oil price not just because they oversee a large share of the world’s oil production, but also because they can flex domestic production at will. They can increase or decrease their own output to affect the global marginal barrel’s price, stabilizing prices (or hiking them) as needed. (This originates partly from geological luck; Saudi Arabia’s reserves seem particularly well suited to rapid ramp-ups or ramp-downs in drilling and pumping.)
That suggests a mirrored role: a “swing consumer.” What if a country had such large oil stockpiles that it could ramp up or ramp down its imports at will, such that it could move global demand for oil at the margin? Such a thing has never existed in the history of the global oil market, at least to my knowledge. America has experimented with mini-versions of this idea in the past; the Biden administration released oil from the Strategic Petroleum Reserve in 2022 to depress prices after Russia invaded Ukraine. Outside of oil, China already plays a similar role in many global mineral markets, single-handedly shifting global prices for iron, lithium, copper, and other commodities.
But China's actions over the past few months suggest that its domestic oil stockpiles might now be so big that the country can play a swing role in global liquid fuels markets. After President Trump announced that he had reached a deal with Iran, I reflected in this newsletter on the fact that the world now had two energy systems, at least in the transport sector: a legacy liquid fuels system and a rival electricity system. These systems’ supply is divided among the world’s powers. The U.S. is the largest oil and gas producer in the world, but China is the largest manufacturer of solar panels, EVs, and batteries.
Yet if China is also now the world's swing consumer of oil, it suggests the country now has much more influence over the world’s most critical energy inputs in any form — fossil, electric, or mineral — than we had once thought. That isn’t my only Heatmap-relevant takeaway from the Iran war. But it is one I suspect we will remember for years to come.
New Jersey’s Frank Pallone, ranking member on the House Energy and Commerce Committee, says “this simply cannot continue.”
It was just yesterday that I wrote about the Ratepayer Protection Act, a bill that would transform into law the voluntary pledge big tech companies signed with the White House to take on additional electric grid costs from their data centers. My argument was that it’s not so much an anti-artificial intelligence or anti-data center bill, but rather a move to insulate further data center development from political pressure stemming from rising electricity costs.
Well, at least one influential lawmaker seems to agree with me. The Democratic ranking member of the House Energy and Commerce Committee, New Jersey Representative Frank Pallone, called for a national data center moratorium before the Wednesday afternoon markup of a series of data center-related bills, the Ratepayer Protection Act among them.
Pallone described the proposals being discussed at the markup as a “useful first step,” but that “compared to the challenges the American power grid is facing, they are not nearly enough.” Instead, he called for “a national AI data center moratorium until we can find a way to ensure they don't harm our nation's air, water, and power bills.”
Pallone cited a slew of efforts in his home state to slow the rapid proliferation of data centers, including a resolution in Asbury Park calling for a statewide moratorium and the city of New Brunswick rejecting a planned data center project earlier this year.
“This simply cannot continue,” Pallone said of the pace of data center development. (When asked for comment, Pallone’s office pointed to his prepared remarks.)
Pallone is not the first Democrat to call for a data center moratorium, but he’s the moratorium supporter who is most closely involved in energy policy at the national level. Senator Bernie Sanders and Representative Alexandria Ocasio-Cortez, two of Congress’ most prominent progressive Democrats, have called for a nationwide moratorium, sponsoring a bill that would enact “a reasonable pause to the development of AI to ensure the safety of humanity,” including a halt to data center construction until a laundry list of conditions were met related to both energy prices and AI safeguards.
The Democrat-controlled New York State legislature also passed a one-year data center moratorium earlier this month, although the bill is still sitting on the desk of Governor Kathy Hochul, a Democrat, awaiting her signature or veto.
Politicians calling for moratoria are trying to catch up with a public that has quickly soured on data centers. A majority of the American public supports a nationwide moratorium, according to polling done by Heatmap, with 40% of respondents giving the idea their strong support.
One reason why Americans increasingly oppose data centers is that they blame the developments for inflating their electricity bills. When Heatmap polled this question last August, 28% of respondents blamed “the construction of new data centers” for rising electricity prices. When we asked again last month, 53% did.
Analysts have looked at electricity price increases in the past five to 10 years and found little consistent relationship with data center construction, though that is not necessarily true everywhere and at all times.
In New Jersey, which is part of the PJM Interconnection electricity market, prices have likely risen based on current and planned data center construction within a grid area that has long had trouble bringing on new generation or building out sufficient transmission. PJM’s independent market monitor has attributed $23 billion in added costs to “existing and forecast data center load” in the system’s capacity auctions.
New Jersey Governor Mikie Sherrill implemented a rate freeze almost immediately following her inauguration earlier this year after years of price hikes and rising bills. Average electricity bills in the state have risen from around $91 per month to $140 per month, according to the Heatmap-MIT Electricity Price Hub, while electricity prices have risen almost 52% in the past five years.
Pallone was skeptical that any intermediate steps have or could work to protect ratepayers.
“Promises by the data center industry and Big Tech that these facilities will bring down costs have fallen flat,” Pallone said at Wednesday’s markup. The Federal Energy Regulatory Commission’s efforts to prompt regional electricity markets to overhaul their interconnection policies “may have promise, but it will take months, if not years, to come to fruition,” he said. The Ratepayer Protection Pledge, meanwhile, has “no enforcement,” and constitutes a “toothless promise from Big Tech.”
“Americans across the country have expressed concern and opposition to the rampant construction of AI data centers, and Congress should take this political groundswell seriously with a data center moratorium,” Pallone concluded. “That's what we need.”
