A personal account of the final act in the fight to pass the United States’ first comprehensive climate law

One year ago, the Inflation Reduction Act became law, throwing the full financial might of the federal government behind the clean energy transition and forever changing the fight against climate change.
Recent polling finds that too few recognize the historical significance of the hundreds of billions of dollars the law invests to make clean energy cheaper for American households, businesses, and industries.
Even fewer people appreciate just how close we came to losing it all.
This is a personal account of the final days of the fight to pass the nation’s first comprehensive climate law, and of how the Inflation Reduction Act remarkably arose from the ashes of near-defeat.
On July 14, 2022, just over a month before eventually becoming law, the budget bill that would eventually become known as the Inflation Reduction Act died. Again.
That evening, Senator Joe Manchin, the coal-state Democrat from West Virginia, called Senate Majority Leader Chuck Schumer to tell him he was done with the long-simmering inter-party negotiations striving to craft a budget bill that could unite all 50 Democratic senators and pass the evenly divided Senate. The stubborn hold-out had already dashed progressive dreams multiple times in the year and a half since the 117th Congress gaveled into session, including dealing the killing blow to the House-passed Build Back Better Act in December 2021.
The news was a shock. Less than two weeks earlier, over the Fourth of July weekend, I was told by Senate staffers party to the budget negotiations that a deal was imminent. They told me to prepare the REPEAT Project, a Princeton University team that I lead and that assesses the impacts of federal energy and climate policies as they are debated, to stand by to run the numbers on a new bill.
But in July 2022, inflation was running at nearly 9% and gasoline prices were over $5 per gallon in many parts of the U.S. Then we got one bad report on the rate of inflation after another, prompting Manchin to say he could no longer support any additional government spending that might further fuel inflation.
Manchin called Schumer on July 14 to say he could no longer continue negotiations, and that he would not support legislation that included any clean energy or climate spending — leaving only a slimmed-down bill focused on health care left in play.
"DEVASTATING... utterly SENSELESS!" I tweeted at the time, using REPEAT Project modeling to illustrate the massive climate gap we would have faced, had that been the end of the story.

And it really did seem like the end.
The tone I heard from Senate staffers that day was very different from the several prior ‘false demises’ of the budget negotiations we had all endured. They were despondent. “I feel like I just wasted the last six years of my life,” one staffer texted me on July 14. So did I.
The next day, Manchin issued an ultimatum: Either Democrats could quickly pass a “skinny” budget bill focused only on health care or they could wait a few weeks to see if inflation improved and try negotiating a larger package in August.
The problem: Basically no one thought inflation would meaningfully cool that quickly, and there was only a few weeks left to pass a law before the August recess, after which Congress would go into full campaign season and nothing would pass.
The game clock was winding down.
Then President Biden threw in the towel. He issued an official statement vowing to keep the climate fight up via executive action but urged the Senate to quickly pass a bill focused only on health care.
Schumer appeared poised to do just that, and a caucus meeting for Senate Democrats was set for the following Tuesday to discuss how to move forward. Since Congress only gets one shot at a budget reconciliation law per fiscal year, if they ended up passing a bill without any climate package, it was game over.
I had been working to advance federal climate policy since 2008. I lived through the demise of the last serious effort to pass a federal climate law in 2009 and 2010. I knew how rare these windows of opportunity to pass meaningful legislation are. And we’d just blown a once-in-a-decade chance. Would we have to wait until the 2030s for our next shot? Could we even survive another decade with the United States standing on the sidelines of the global climate fight?
By July 16, I had apparently had enough time to go through the various stages of grief, arriving at bargaining (or perhaps denial). “It’s just not okay to end like this, with Manchin walking away from the deal and the rest of the caucus just quietly accepting that!” I wrote in a text to a key Senate staffer. “There’s got to be at least a dozen [Senate] members who are furious and could be unwilling to accept that in the end, right?”
“Working on it 😄,” the staffer replied.
And just like that, while many gave up and others fumed, staff from just a handful of Senate offices and a rag-tag group of allied individuals and advocacy groups got back to what we’d been doing since the start: doggedly working the problem to find some way to passage.
Even then, I had very little faith our efforts would succeed. I just knew that the game clock had a few seconds left on it, time enough to run a couple more Hail Mary plays, and I wanted to be able to look my kids in the eye some day and say, “We failed, but we truly tried everything we could.”
So we got back to work.
So how did we get Manchin back to the negotiating table?
From my limited perspective, three things worked.
First, the concern that climate spending would stoke inflation was bogus. The budget deal under negotiation was doubly paid for, raising twice as much new revenue as it spent. What’s more, the spending plan was estimated to be in the ballpark to $30 to $50 billion per year spread over a decade, or less than 1% of our roughly six trillion dollar federal budget.
The climate spending was peanuts, and any honest macroeconomist would say that the budget deal would have a mild, fiscally contractionary effect at best or no effect on inflation at worst. Plus, the proposals specifically took aim at two key drivers of inflation: health care costs and energy costs.
Either Manchin was honest in his inflation fears but misappreciating the issues, or he was trying to give himself cover to scuttle the bill.
Our so-called “Never Give Up Caucus” took him at face value. To address his inflation concerns, allies succeeded in getting inflation-hawk-in-chief Larry Summers, the conservative leaning Penn-Wharton Budget Model team, and the deficit hawkish head of the Committee for a Responsible Federal Budget to tell Manchin (and the press) that the deal would cut the deficit and not raise prices.
Second, the many vested interests that stood to gain from the clean energy package were mobilized and pushed Manchin hard not to leave them high and dry.
This was always a key part of the political strategy of the clean energy package: rather than focus on pricing carbon emissions and making fossil energy more expensive (as Congress had attempted in 2009), the budget bill would instead provide a wide-ranging set of direct subsidies — tax credits, grants, loan programs — to make climate-friendly technologies cheaper and help build up manufacturing of clean energy components in the U.S. Concentrated beneficiaries create organized power to back the bill. That was the theory, and it was time to put it to the test.
The pressure campaign to get Manchin back to the table was “across the board,” according to National Wildlife Federation CEO Collin O’Mara, who was one of the most dogged and effective organizers during those pivotal final days.
Executives from renewable energy companies reminded Manchin that billions of dollars of investment were at stake.
The United Mine Workers of America pushed Manchin not to walk away from his promise to create a permanent trust fund for miners suffering from black lung disease, which the budget bill would do.
In my personal estimation, the most effective voices were probably from those sectors Manchin had styled himself as personally championing as chairman of the Senate Energy Committee: carbon capture, nuclear power, hydrogen, and advanced manufacturing.
A senior executive with a utility operating in Appalachia reportedly told Manchin: “We know coal plants are ultimately going to close. What is going to replace them? What are the jobs? What are we transitioning to? In this case, we are going to explore hydrogen, new nuclear and get manufacturing in the state.”
Manchin received incoming pressure to pass a bill from the Carbon Capture Coalition, oil companies like BP with big plans to invest in hydrogen, and Nucor, the nation’s largest steel maker, which planned new investments in West Virginia in part to supply growing demand for steel for burgeoning renewable energy industries.
Utilities like Constellation and Duke reminded Manchin that this law was our best shot at preserving the nation’s existing nuclear fleet, which provides about a fifth of our electricity without contributing to air pollution or climate change.
Bill Gates, who has invested in nuclear and energy storage startups, called Manchin personally. And executives at a Gates-backed battery company with plans for a West Virginia manufacturing hub explained to Manchin’s staff how the bill’s incentives would accelerate their growth trajectory.
Third, a few key senators that Manchin personally trusted or respected, including John Hickenlooper of Colorado, Chris Coons of Delaware, Tina Smith of Minnesota, Mark Warner of Virginia, and Ron Wyden of Oregon, reportedly pressed him with direct personal appeals.
I imagine their pitches either made the political case — did Manchin really want to send his party into the midterms having utterly failed on their domestic policy agenda? — or a personal one, emphasizing the opportunity to secure his legacy and the admiration of his grandchildren.
I don’t think we should discount the importance of these personal appeals. At the end of the day, senators are humans too. They crave the respect of their colleagues (at least those they admire). And everyone wants to be the hero of their own story, not the villain.
Which of these (or other parallel efforts I don't know about) pushed Manchin back to the table? Who knows what went through his mind in the end. But somehow, against virtually all expectations, it worked.
We didn’t know it until later, but by as early as Tuesday, July 19, Manchin and Schumer, with just a couple key aids each, began meeting in secret somewhere in the Senate offices and got back to work.
No one else had any idea this was happening.
Like others working to save the bill, I spent the next week continuing to talk to press, allies, congressional staff, etc., marshaling talking points and data, mobilizing various interests to pressure Manchin, and doing everything we could to convince the stubborn senator to make a deal that would get a climate package into law. Little did we know, he was already back at it.
In fact, a little over a week later, on Wednesday, July 27, Manchin issued a statement that shocked everyone: He and Leader Schumer had reached a deal after all and were unveiling a full-fledged bill to be called “The Inflation Reduction Act.”
“The Inflation Reduction Act of 2022 addresses our nation’s energy and climate crisis by adopting commonsense solutions through strategic and historic investments that allow us to decarbonize while ensuring American energy is affordable, reliable, clean and secure,” Manchin wrote.
The full text of the bill dropped later that evening, and we were blown away to see how much of the original climate package from the ill-fated Build Back Better Act was retained by this new legislation.
The deal contained roughly $370 billion in estimated climate and clean energy spending, an historic package. All the key tax incentives were still in the proposal, including credits for clean electricity, electric vehicles, and heat pumps. Major grant programs were funded at similar levels. Even a new fee on methane pollution from the oil and gas sector had survived. In fact, a tax credit for U.S. clean energy manufacturing had even been expanded, apparently at Manchin’s request, to support production of batteries and their components and the mining and processing of critical minerals.
Rather than lose it all, we were poised to win nearly everything we’d hoped for.
“Holy shit. Stunned, but in a good way,” wrote Senator Tina Smith, a tireless advocate for the climate package, on Twitter. “$370B for climate and energy … BFD.”
It took us a couple weeks to run the numbers, but once we did, REPEAT Project estimated on August 4 that the Inflation Reduction Act, or IRA (pronounce it like your friendly Uncle Ira!), would cut emissions by about one billion metric tons per year in 2030 and retained about 80% of the cumulative emissions reductions of the larger Build Back Better package.

IRA could get the United States to about 42% below our peak historical emissions by 2030, we estimated at the time. (REPEAT Project’s latest updated analysis published last month revises 2030 emissions under IRA to 37-41% below peak.) That was still short of the target of 50% below peak levels that President Biden had committed the country to on the world stage, but the proposed legislation was a true game changer that gave us a fighting chance to hit that goal.
After the Manchin-Schumer deal dropped, we were off to the races.
Manchin shifted from the package’s chief obstacle to its chief spokesperson, stumping for the bill on Fox and haranguing senators on the floor alongside Schumer to get IRA passed during an exhausting, overnight “vote-a-rama.” After a 16-hour process where Republicans proposed amendment after amendment to be shot down one by one by a united Democratic caucus — plus a little last minute drama wherein Kyrsten Sinema nearly killed the bill to save private equity firms billions in taxes — the Inflation Reduction Act passed the Senate at 3:17 PM on August 7, 51-50, with Vice President Harris casting the deciding vote.
The House passed IRA in turn on August 14, and President Biden signed it into law two days later. The rest, as they say, is history.
We’re still writing that history, but it’ll be forever changed by passage of the landmark law. And we almost lost it all.

The companies just launched a major VPP play.
For all the hype surrounding virtual power plants, they’re still a niche player on the U.S. electric grid. A new partnership between three of the biggest residential energy companies in the country — Tesla, Sunrun, and Renew Home — aims to recast VPPs into a leading role.
The companies announced on Wednesday that they have more than 16 gigawatts of dispatchable VPP capacity available today to deliver to utilities and data center developers throughout the country. That’s about the same as 16 nuclear reactors, except instead of generating power round the clock from a central plant, the companies aggregate unused electricity capacity from thousands of individual home solar and battery systems and programmable thermostats, and can make it available for several hours at a time.
Today, the companies bid these resources into electricity markets as a sort of bespoke grid service. A few times per year — often in the summer months when demand spikes — the grid operator in California might ask Sunrun to switch on its VPP to prevent a blackout. That means Sunrun’s rooftop solar and battery customers all either begin exporting excess power to the grid or rely more on their energy storage systems for their own power needs, reducing strain on the grid. Tesla operates similar programs, some in partnership with Sunrun. Renew Home, which spun out of Google Nest, does the same thing but with thermostats and water heaters, nudging temperatures on thousands of devices up or down during peak demand hours.
“A lot of our assets are enrolled in a contract where they can be used up to 20 times per year,” Paul Dickson, the president and chief revenue officer of Sunrun, told me. Now the company, along with its partners, are making the pitch to utilities and hyperscalers to view VPPs as 365-day resources, and more fully integrate them into their grid planning.
It’s a “turnkey” solution, the companies wrote in a press release, “deployable in months, not years,” that requires “no additional hardware, software, interconnection, water, or land usage for offtaking parties.”
VPPs also typically kick back some of the proceeds they earn from the electricity market to the residential customers hosting the solar panels, batteries, and programmable thermostats providing the power, meaning they can meet growing energy demand while helping to lower household energy bills. Sunrun and Renew Home paid out a combined $67 million in customer rewards last year.
About 60% of the 16 gigawatts the companies have available are tied to Renew Home’s enrolled devices, with the remaining 40% coming from Sunrun and Tesla’s solar and battery assets, Dickson told me. The capacity is also spread out geographically. There’s about 1.7 gigawatts available in Texas — the second largest data center market in the country, Dickson pointed out. There’s 300 megawatts available in Virginia, which the companies expect to grow to 500 megawatts by 2030.
“Unlike a traditional power plant that's fixed in size, this number grows every single day as the combined three companies continue to add additional capacity,” Dickson said. Sunrun alone plans to more than double its energy storage capacity by the end of 2028.
If utilities and large industrial customers buy the VPP pitch, the companies will be able to expand even more quickly, he added. If regulators or utilities come back and say, we’ll take your existing capacity today, and if you can add another gigawatt in the next year, here’s what we’ll pay, Sunrun could potentially reduce the upfront cost to customers to host the solar and battery installations, driving faster adoption.
The new partnership follows a similar announcement earlier this month from the VPP company Voltus, which signed a three-year agreement with Google. Voltus will provide up to 100 megawatts per year of capacity for Google in PJM, the country’s largest (and most constrained) electricity market covering much of the Midwest and mid-Atlantic. In that case, however, Voltus is using the deal with Google to finance the VPP, with the capacity set to come online by 2027.
The Tesla/Sunrun/Renew Home group is simply announcing they are open for business — they haven’t signed up any offtakers yet. Dickson told me the companies wanted to “make everybody aware that there is this uncontracted capacity, and make sure that it goes to the place that it can be most impactful.” Wednesday’s announcement is accompanied by a live map that shows where the capacity is. The companies did, however, already bid over a gigawatt of capacity into PJM, the larger energy market that Virginia is a part of, as part of its emergency procurement to meet near-term load growth in the region, and are waiting to hear if they were selected.
Last year, the electrification advocacy group Rewiring America published a paper arguing that hyperscalers could free up grid capacity for at least a third of the load growth expected from data centers if they paid for residential households to get heat pumps. All of that capacity would simply be the result of swapping inefficient appliances for more efficient versions, reducing the overall energy use of the homes. If hyperscalers also financed residential solar and storage upgrades, they could more than meet data center demand, the report posited.
That’s not how these VPP proposals are going to work — residential customers will still have to pay something to Sunrun and Tesla for their solar panels and batteries. But Ari Matusiak, the founder and CEO of Rewiring America, told me he viewed these new VPP partnerships as a step in that direction. Today, energy markets are largely bifurcated between residential market activity and large industrial customers. “Where we are going is toward a world where we think about the household as actual energy infrastructure and not simply an end of the line billpayer,” he said. “Once you start doing that, it changes the economics of how those household upgrades are treated and what the opportunities are.”
Current conditions: The warehouse fire in Boyle Heights is raging for a third day, spewing dark smoke over the Downtown Los Angeles skyline • The death toll from Western Europe’s heatwave has reached into the dozens • An 18-wheeler carrying more than 400 beehives overturned in eastern Texas and filled a small neighborhood with more than 2 million honeybees.
Wally World is soon to be powered by the atom. On Tuesday, Walmart announced a 15-year deal with Constellation, the nation’s largest operator of nuclear plants, for a chunk of the electricity coming from the Dresden Clean Energy Center in Illinois. The agreement included about 176 megawatts of wholesale supply from the two-reactor station southwest of Chicago, including 30 megawatts of expanded generating capacity through “uprates” — upgrades that allow operators to get more power out of an existing unit. Over the past two years, tech giants such as Google, Microsoft, and Meta, have bought shares of the power coming from nuclear power stations as the companies sought steady supplies of clean electricity for their burgeoning data centers. But the Walmart deal stands out as one of the first to involve a major brick-and-mortar retailer. “We’re constantly evaluating new capabilities and energy solutions that help ensure the electricity we rely on is dependable, responsibly produced, and built to support long-term growth,” Shayne Wahlmeier, Walmart’s senior vice president of energy, said in a statement.
The Trump administration just unveiled one of its biggest bets on nuclear power yet. The Department of Energy announced $17.5 billion in low-interest loans for utilities to pay for the equipment needed to order new Westinghouse AP1000 reactors. The program marks arguably the most significant effort yet to reclaim U.S. control over its flagship reactor design. While the two 1,100-megawatt units completed at Southern Company’s Alvin W. Vogtle Generating Station in 2023 and 2024 were the first installed in the U.S., China has been building its own version of the reactors at an industrial scale for years. The program will support up to 10 reactors, including two per venture with as many as five utilities. The power companies, currently in talks with the administration, have not yet been named. But Dan Sumner, the chief executive of Westinghouse Electric, told The Wall Street Journal the deal “really kick-starts fleet-scale nuclear development in the United States.” As my colleague Robinson Meyer wrote last night: “I hesitate to praise the project's climate bonafides at the risk of discouraging the Trump administration, but it is worth noting that if this project were to succeed, it would be one of the largest state-assisted build-outs of zero-carbon electricity in recent American history. But it would still take some time to arrive: These reactors aren’t forecast to come online til 2035.”
Yet another behemoth solar farm has come online. On Tuesday, the developer rPlus Energies said its Green River Energy Center had started operations. The facility in central Utah with 400-megawatts of solar panels and 1,600 megawatt-hours of batteries is now the largest solar-and-storage plant within PacifiCorp’s six-state territory out west, including Oregon, Washington, California, Utah, Wyoming, and Idaho. “Operation Gigawatt is about ensuring Utah has the reliable, homegrown energy needed to power opportunity for generations,” Utah Governor Spencer Cox, a Republican, said in a statement. “Green River Energy Center represents the kind of large-scale energy investment we need to deliver reliable energy, support rural Utah, and help power the next generation of prosperity across our state.”
The opening comes as solar is now generating more U.S. power than coal, as I told you recently.

The Supreme Court ruled Tuesday that Exxon Mobil has the right to sue a Cuban-owned company to recoup more than $70 million in 1960 dollars from an oil complex seized by the Cuban government after Fidel Castro’s revolution. Havana later transferred the ownership of the refinery, terminals, plants, and service stations to Corporación Cimex, the state-owned conglomerate. The lawsuit could now see the oil major try to recover more than $1 billion in losses. “Today’s decision is a critical moment in a 60 year effort to be compensated for what the Cuban government illegally seized,” Exxon spokesperson Todd Spitler told E&E News in an emailed statement. “It reflects two things: the merits of our argument and the fact that our company will fight a good fight for as long as it takes.”
The Trump administration understands the importance of refining cobalt — that’s why, as I reported last year, the Pentagon’s Defense Logistics Agency is pumping money into a startup that promises a new and cheap way to process the mineral. Canada’s Sherritt International started shutting down its Fort Saskatchewan refinery after the U.S. expanded sanctions on Cuba, halting exports of a feedstock supply needed for the plant in Alberta, Canada. The move, in addition to the Supreme Court ruling, come amid intensifying pressure by Washington on the Cuban regime.
California is once again following a New York trend. Just weeks after Albany sued to stop the Trump administration’s bid to pay TotalEnergies to give up its offshore wind projects, Sacramento is joining the litigation. “At a time when the country needs more reliable and sustainable power supply, the Trump Administration is busy using taxpayer money to strike backroom buyouts that make clean-energy projects disappear,” California Attorney General Rob Bonta said in a statement. “California won’t stand idly by as the Trump Administration illegally strikes deals to kill offshore wind projects and replace them with more windfalls for his fossil fuel friends; we’re putting the Administration on notice that we intend to sue.”
Rob checks in with Commodity Context’s Rory Johnston as the Iran War (hopefully) draws to a close.
When Iran closed the Strait of Hormuz earlier this year, experts projected oil prices would go to $200 a barrel. But then… they didn’t. In fact, while gasoline prices rose in the United States, and Europe and Asia suffered higher costs, the resulting energy crisis wasn’t even as bad as what followed Russia’s 2022 invasion of Ukraine.
Why? China. The country seems to have absorbed the costs of Trump’s war of choice by releasing hundreds of millions of barrels from its strategic stockpile. On this episode of Shift Key, Rob is joined by Rory Johnston, an oil markets researcher and the author of the Commodity Context newsletter. They discuss China’s massive (and quiet) intervention, why it’s “the most important thing we learned” from the Iran War, and what it means for the future of energy and geopolitics. Shift Key is hosted by Robinson Meyer, the founding executive editor of Heatmap News.
