The government agency is quietly funding some of the industry’s most exciting early stage companies.
When the George W. Bush administration established the Advanced Research Projects Agency - Energy, better known as ARPA-E, the number one goal for the new agency sounded an ambitious and patriotic note: “To enhance the economic and energy security of the United States through the development of energy technologies.” And from that uncontroversial foundation, a bipartisan bastion of cleantech innovation was born.
I knew I wanted to dig into the critical role that ARPA-E plays in the climate tech funding landscape after Rajesh Swaminathan, a partner at Khosla Ventures, told me that he views the agency as the “least talked about VC in town.” So I reached out to ARPA-E’s director, Evelyn Wang, to learn more.
Of course, ARPA-E isn’t actually a venture capital firm — it provides no-strings-attached funding to promising energy projects rather than aiming for a return on investment. “So a little bit different,” Wang told me. “Our mission is very much focused on energy independence, reducing greenhouse gas emissions, and enhancing energy efficiency.”
The Bush administration established ARPA-E in 2007 with the passage of the America COMPETES Act, which aimed to improve the technological competitiveness of the United States via investments in research and development. But the agency was funded for the first time in 2009, under Obama, as a part of an $800 billion stimulus package in response to the Great Recession. A substantial chunk of that funding — $90 billion — was allocated for clean energy, which the administration would go on to boast amounted to the “largest single investment in clean energy in history.”
Yet whether it’s been Bush or Obama — or Trump or Biden — in the White House, the messaging around ARPA-E has always trended less towards renewables and climate mitigation and more towards energy security and economic competitiveness. As the name suggests, ARPA-E is modeled after the Defense Advanced Research Projects Agency, or DARPA, which was established in 1958 in response to the Soviet’s launch of the Sputnik satellite. DARPA has since helped birth such little-known tech as the entire internet, GPS, automated voice recognition, and self-driving cars.
But while the de facto customer for DARPA-developed tech is always the Department of Defense, the pathway to commercialization for ARPA-E projects mainly relies on private sector interest. In that sense, the goal of ARPA-E is neatly aligned with that of venture capitalists: Get tech to market. Because while scientific learnings are all well and good, Wang said that “ultimately, we need to see these technologies commercialized — to actually be out there — to actually affect the ecosystem and change the energy landscape.”
Since ARPA-E can eschew the profit motive, it’s able to fund high-risk, high-reward projects at the earliest stages, when most investors would be reluctant to take on that level of uncertainty. Yet the inherent risk means the success rate for ARPA-E projects as measured by metrics such as the number of companies it’s spawned (157), exits via mergers, acquisitions or IPOs (30), and additional partnerships with other government agencies (360), can seem low compared to the 1,590 projects that the agency has funded over the past 15 years. A climate tech investor I spoke with on background told me that while they love ARPA-E and are glad it exists, they were expecting more success stories by now.
That’s at least partially because even after a project is funded and proof-of-concept has been demonstrated, there’s often still a ways to go before investors are ready to jump in. “I think when we first stood up ARPA-E, the idea was that at that point, it would be sufficiently de-risked for the private sector to then pick it up and invest,” Wang told me. But frequently, that hasn’t been the case. ARPA-E usually funds projects for one to three years, but often climate tech innovation relies on deeply complex and thus inherently slow advancements in science and engineering — think fusion energy, novel battery development, or direct air capture. Many venture funds have 10 year time horizons, so if investors don’t see a payoff happening in that timeframe, they’ll probably hold back.
The investor I spoke with on background told me that ARPA-E has become more effective in partnership with the Office of Clean Energy Demonstrations, established in 2021 under the Department of Energy, which uses its $25 billion budget to create model buildouts of new technology with private sector partners. Earlier this year, OCED selected six ARPA-E awardees focused on industrial decarbonization to receive a combined total of up to $775 million.
Even so, the investor told me, ARPA-E funding alone still might not be enough to get companies to a place where OCED would be interested. To help close that gap, ARPA-E started a program called SCALEUP, a mouthful of an acronym for The Seeding Critical Advances for Leading Energy (Technologies) with Untapped Potential, in 2019. It provides a small number of ARPA-E projects with follow-on funding to further prove out their concepts — provided they can identify at least one commercialization partner such as a potential customer, end-user, or supplier willing to take a stake in the development of the tech and help it get to market.
So far, Wang says the program has yielded some successes. The list includes LongPath Technologies, which monitors methane emissions and leaks in the oil and gas industry and received a conditional loan last year from the DOE’s Loan Programs Office; Natron Energy, which just opened the first commercial-scale sodium-ion battery production facility in the U.S.; and Sila, a battery materials manufacturer that has raised over $1.3 billion in total, and secured contracts with Mercedes-Benz and Panasonic.
When you look at ARPA-E’s success rate in terms of dollars in and dollars out, though, it starts to look pretty darn efficacious as is. Since 2009, ARPA-E has provided more than $3.8 billion for research and development, leading to over $12.6 billion in private-sector follow-on funding, while the 30 exits to date have yielded a combined market valuation of $22.2 billion. And since it often takes climate tech companies around a decade to mature to the point where they’re ready for an exit event, many of ARPA-E’s companies have yet to reach the acquisition or IPO threshold.
These days, ARPA-E projects are facing a completely different funding landscape than in the 2000s — one ripe with both excitement and cash as well as increasing competition. So while Wang told me that the agency’s goal is always to look for “technological whitespace” in the energy landscape, “it's getting more crowded,” she said. “And I think in that context, we've strategically decided that we should also think about broader vision type efforts.” To that end, ARPA-E has identified three comprehensive focus areas: developing clean primary energy sources such as geothermal, small modular nuclear reactors, fusion and geologic hydrogen; power delivery for non-electrical sources, such as energy transported via hydrogen or heat; and figuring out how to source carbon sustainably, such as via engineered plants and algae.
Now that ARPA-E has been supporting projects for a decade and a half, it’s getting more experimental when it comes to developing novel testbeds for its tech. Exhibit A is the San Antonio International Airport, whichrecently signed a memorandum of understanding with the agency to deploy a series of ARPA-E backed technologies.
Many major airports are actually higher tech than passengers may realize, and given the mounting pressure on the aviation industry to decarbonize, they’re also open to novel sustainability solutions. In San Antonio, the airport is deploying EV chargers from Imagen Energy and sodium-ion battery tech from Natron Energy, both of which could help electrify their ground vehicles, as well as a distributed energy management system from Autogrid, which allows airports to control their virtual power plants, microgrids, EV fleet, and demand response measures. Other tech, such as hybrid-electric planes from Ampaire, could be integrated into the airport in the future.
That’s a lot of technology development for not many headlines. And when a company raises a major round or goes public, sometimes you have to dig deep to discover their ARPA-E origins. Hence, the “least talked about VC in town” comment. In some sense, Wang says, this is intentional.
“When we think about success, if our teams, our companies are successful, and they shine, then we shine,” she told me, and maybe that’s the way it should continue to be. Because while advertising government investment in anything seen as “clean” or “green” can immediately draw both partisan praise and ire, funding for ARPA-E has been steadily creeping up nearly every year since 2015. And yes, that includes the Trump era, even though the former president seemingly wanted to axe the agency altogether. Congress, it turned out, was not on board with that plan.
“Our mission is about energy independence and bolstering our economy and I think everyone agrees with this mission,” Wang told me. “Everyone,” of course, will always be an overstatement. But perhaps Wang is right that the agency does function better as a behind-the-scenes player. As she put it, speaking of the companies the agency funds, “It’s more about them, right? And how that affects the ecosystem, and helps our nation in terms of what we need to do as a country, and how that sets an example for the world.”
Editor’s note: This story initially misstated the size of the American Recovery and Reinvestment Act and the amount of funding allocated to clean energy.

Recovering from the Los Angeles wildfires will be expensive. Really expensive. Insurance analysts and banks have already produced a wide range of estimates of both what insurance companies will pay out and overall economic loss. AccuWeatherhas put out an eye-catching preliminary figure of $52 billion to $57 billion for economic losses, with the service’s chief meteorologist saying that the fires have the potential to “become the worst wildfire in modern California history based on the number of structures burned and economic loss.” On Thursday, J.P. Morgan doubled its previous estimate for insured losses to $20 billion, with an economic loss figure of $50 billion — about the gross domestic product of the country of Jordan.
The startlingly high loss figures from a fire that has only lasted a few days and is (relatively) limited in scope show just how distinctly devastating an urban fire can be. Enormous wildfires thatcover millions of acres like the 2023 Canadian wildfires can spew ash and particulate matter all over the globe and burn for months, darkening skies and clogging airways in other countries. And smaller — and far deadlier fires — than those still do not produce the same financial roll.
It’s in coastal Southern California where you find large population centers areas known by all to be at extreme risk of fire. And so a fire there can destroy a whole neighborhood in a few hours and put the state’s insurance system into jeopardy.
One reason why the projected economic impacts of the fires are so high is that the structures that have burned and the land those structures sit on are very valuable. Pacific Palisades, Malibu, and Santa Monica contain some of the most sought-after real estate on planet earth, with typical home prices over $2 million. Pacific Palisades itself has median home values of around $3 million, according to JPMorgan Chase.
The AccuWeather estimates put the economic damage for the Los Angeles fires at several times previous large, urban fires — the Maui wildfire in 2023 was estimated to cause around $14 billion of economic loss, for example — while the figure would be about a third or a quarter of a large hurricane, which tend to strike areas with millions of people in them across several states.
“The fires have not been contained thus far and continue to spread, implying that estimates of potential economic and insured losses are likely to increase,” the JPMorgan analysts wrote Thursday.
That level of losses would make the fires costlier in economic terms than the 2018 Butte County Camp Fire, whose insured losses of $10 billion made it California’s costliest at the time. That fire was far larger than the Los Angeles fires, spreading over 150,000 acres compared to just over 17,000 acres for the Palisades Fire and over 10,000 acres for the Eaton Fire. It also led to more than 80 deaths in the town of Paradise.
So far, around 2,000 homes have been destroyed,according to the Los Angeles Times,a fraction of the more than 19,000 structures affected by the Camp Fire. The difference in estimated losses comes from the fact that homes in Pacific Palisades weigh in at more than six times those in rural Butte, according to JPMorgan.
While insured losses get the lion’s share of attention when it comes to the cost impacts of a natural disaster, the potential damages go far beyond the balance sheet of insurers.
For one, it’s likely that many affected homeowners did not even carry insurance, either because their insurers failed to renew their existing policies or the homeowners simply chose to go without due to the high cost of what insurance they could find. “A larger than usual portion of the losses caused by the wildfires will be uninsured,” according to Morningstar DBRS, which estimated total insured losses at more than $8 billion. Many homeowners carry insurance from California’s backup FAIR Plan, which may itself come under financial pressure, potentially leading to assessments from the state’s policyholders to bolster its ability to pay claims.
AccuWeather arrived at its economic impact figure by looking not just at losses from property damage but also wages that go unearned due to economic activity slowing down or halting in affected areas, infrastructure that needs to be repaired, supply chain issues, and transportation snarls. Even when homes and businesses aren’t destroyed, people may be unable to work due to evacuations; businesses may close due to the dispersal of their customers or inability of their suppliers to make deliveries. Smoke inhalation can lead to short-, medium-, and long-term health impacts that take a dent out of overall economic activity.
The high level of insured losses, meanwhile, could mean that insurers’ will see less surplus and could have to pay more for reinsurance, Nancy Watkins, an actuary and wildfire expert at Milliman, told me in an email. This may mean that they would have to shed yet more policies “in order to avoid deterioration in their financial strength ratings,” just as California has been trying to lure insurers back with reforms to its dysfunctional insurance market.
The economic costs of the fire will likely be felt for years if not decades. While it would take an act of God far stronger than a fire to keep people from building homes on the slopes of the Santa Monica Mountains or off the Pacific Coast, the city that rebuilds may be smaller, more heavily fortified, and more expensive than the one that existed at the end of last year. And that’s just before the next big fire.
Suburban streets, exploding pipes, and those Santa Ana winds, for starters.
A fire needs three things to burn: heat, fuel, and oxygen. The first is important: At some point this week, for a reason we have yet to discover and may never will, a piece of flammable material in Los Angeles County got hot enough to ignite. The last is essential: The resulting fires, which have now burned nearly 29,000 acres, are fanned by exceptionally powerful and dry Santa Ana winds.
But in the critical days ahead, it is that central ingredient that will preoccupy fire managers, emergency responders, and the public, who are watching their homes — wood-framed containers full of memories, primary documents, material wealth, sentimental heirlooms — transformed into raw fuel. “Grass is one fuel model; timber is another fuel model; brushes are another — there are dozens of fuel models,” Bobbie Scopa, a veteran firefighter and author of the memoir Both Sides of the Fire Line, told me. “But when a fire goes from the wildland into the urban interface, you’re now burning houses.”
This jump from chaparral shrubland into neighborhoods has frustrated firefighters’ efforts to gain an upper hand over the L.A. County fires. In the remote wilderness, firefighters can cut fire lines with axes, pulaskis, and shovels to contain the blaze. (A fire’s “containment” describes how much firefighters have encircled; 25% containment means a quarter of the fire perimeter is prevented from moving forward by manmade or natural fire breaks.)
Once a fire moves into an urban community and starts spreading house to house, however, as has already happened in Santa Monica, Pasadena, and other suburbs of Los Angeles, those strategies go out the window. A fire break starves a fire by introducing a gap in its fuel; it can be a cleared strip of vegetation, a river, or even a freeway. But you can’t just hack a fire break through a neighborhood. “Now you’re having to use big fire engines and spray lots of water,” Scopa said, compared to the wildlands where “we do a lot of firefighting without water.”
Water has already proven to be a significant issue in Los Angeles, where many hydrants near Palisades, the biggest of the five fires, had already gone dry by 3:00 a.m. Wednesday. “We’re fighting a wildfire with urban water systems, and that is really challenging,” Los Angeles Department of Water and Power CEO Janisse Quiñones explained in a news conference later that same day.
LADWP said it had filled its 114 water storage tanks before the fires started, but the city’s water supply was never intended to stop a 17,000-acre fire. The hydrants are “meant to put out a two-house fire, a one-house fire, or something like that,” Faith Kearns, a water and wildfire researcher at Arizona State University, told me. Additionally, homeowners sometimes leave their sprinklers on in the hopes that it will help protect their house, or try to fight fires with their own hoses. At a certain point, the system — just like the city personnel — becomes overwhelmed by the sheer magnitude of the unfolding disaster.
Making matters worse is the wind, which restricted some of the aerial support firefighters typically employ. As gusts slowed on Thursday, retardant and water drops were able to resume, helping firefighters in their efforts. (The Eaton Fire, while still technically 0% contained because there are no established fire lines, has “significantly stopped” growing, The New York Times reports). Still, firefighters don’t typically “paint” neighborhoods; the drops, which don’t put out fires entirely so much as suppress them enough that firefighters can fight them at close range, are a liability. Kearns, however, told me that “the winds were so high, they weren’t able to do the water drops that they normally do and that are an enormous part of all fire operations,” and that “certainly compounded the problems of the fire hydrants running dry.”
Firefighters’ priority isn’t saving structures, though. “Firefighters save lives first before they have to deal with fire,” Alexander Maranghides, a fire protection engineer at the National Institute of Standards and Technology and the author of an ongoing case study of the 2018 Camp fire in Paradise, California, told me. That can be an enormous and time-consuming task in a dense area like suburban Los Angeles, and counterintuitively lead to more areas burning down. Speaking specifically from his conclusions about the Camp fire, which was similarly a wildland-urban interface, or WUI fire, Maranghides added, “It is very, very challenging because as things deteriorate — you’re talking about downed power lines, smoke obstructing visibility, and you end up with burn-overs,” when a fire moves so quickly that it overtakes people or fire crews. “And now you have to go and rescue those civilians who are caught in those burn-overs.” Sometimes, that requires firefighters to do triage — and let blocks burn to save lives.
Perhaps most ominously, the problems don’t end once the fire is out. When a house burns down, it is often the case that its water pipes burst. (This also adds to the water shortage woes during the event.) But when firefighters are simultaneously pumping water out of other parts of the system, air can be sucked down into those open water pipes. And not just any air. “We’re not talking about forest smoke, which is bad; we’re talking about WUI smoke, which is bad plus,” Maranghides said, again referring to his research in Paradise. “It’s not just wood burning; it’s wood, plastics, heavy metals, computers, cars, batteries, everything. You don’t want to be breathing it, and you don’t want it going into your water system.”
Water infrastructure can be damaged in other ways, as well. Because fires are burning “so much hotter now,” Kearns told me, contamination can occur due to melting PVC piping, which releases benzene, a carcinogen. Watersheds and reservoirs are also in danger of extended contamination, particularly once rains finally do come and wash soot, silt, debris, and potentially toxic flame retardant into nearby streams.
But that’s a problem for the future. In the meantime, Los Angeles — and lots of it — continues to burn.
“I don’t care how many resources you have; when the fires are burning like they do when we have Santa Anas, there’s so little you can do,” Scopa said. “All you can do is try to protect the people and get the people out, and try to keep your firefighters safe.”
Plus 3 more outstanding questions about this ongoing emergency.
As Los Angeles continued to battle multiple big blazes ripping through some of the most beloved (and expensive) areas of the city on Thursday, a question lingered in the background: What caused the fires in the first place?
Though fires are less common in California during this time of the year, they aren’t unheard of. In early December 2017, power lines sparked the Thomas Fire near Ventura, California, which burned through to mid-January. At the time it was the largest fire in the state since at least the 1930s. Now it’s the ninth-largest. Although that fire was in a more rural area, it ignited for some of the same reasons we’re seeing fires this week.
Read on for everything we know so far about how the fires started.
Five major fires started during the Santa Ana wind event this week:
Officials have not made any statements about the cause of any of the fires yet.
On Thursday morning, Edward Nordskog, a retired fire investigator from the Los Angeles Sheriff’s Department, told me it was unlikely they had even begun looking into the root of the biggest and most destructive of the fires in the Pacific Palisades. “They don't start an investigation until it's safe to go into the area where the fire started, and it just hasn't been safe until probably today,” he said.
It can take years to determine the cause of a fire. Investigators did not pinpoint the cause of the Thomas Fire until March 2019, more than two years after it started.
But Nordskog doesn’t think it will take very long this time. It’s easier to narrow down the possibilities for an urban fire because there are typically both witnesses and surveillance footage, he told me. He said the most common causes of wildfires in Los Angeles are power lines and those started by unhoused people. They can also be caused by sparks from vehicles or equipment.
At about 27,000 acres burned, these fires are unlikely to make the charts for the largest in California history. But because they are burning in urban, densely populated, and expensive areas, they could be some of the most devastating. With an estimated 2,000 structures damaged so far, the Eaton and Palisades fires are likely to make the list for most destructive wildfire events in the state.
And they will certainly be at the top for costliest. The Palisades Fire has already been declared a likely contender for the most expensive wildfire in U.S. history. It has destroyed more than 1,000 structures in some of the most expensive zip codes in the country. Between that and the Eaton Fire, Accuweather estimates the damages could reach $57 billion.
While we don’t know the root causes of the ignitions, several factors came together to create perfect fire conditions in Southern California this week.
First, there’s the Santa Ana winds, an annual phenomenon in Southern California, when very dry, high-pressure air gets trapped in the Great Basin and begins escaping westward through mountain passes to lower-pressure areas along the coast. Most of the time, the wind in Los Angeles blows eastward from the ocean, but during a Santa Ana event, it changes direction, picking up speed as it rushes toward the sea.
Jon Keeley, a research scientist with the US Geological Survey and an adjunct professor at the University of California, Los Angeles told me that Santa Ana winds typically blow at maybe 30 to 40 miles per hour, while the winds this week hit upwards of 60 to 70 miles per hour. “More severe than is normal, but not unique,” he said. “We had similar severe winds in 2017 with the Thomas Fire.”
Second, Southern California is currently in the midst of extreme drought. Winter is typically a rainier season, but Los Angeles has seen less than half an inch of rain since July. That means that all the shrubland vegetation in the area is bone-dry. Again, Keeley said, this was not usual, but not unique. Some years are drier than others.
These fires were also not a question of fuel management, Keeley told me. “The fuels are not really the issue in these big fires. It's the extreme winds,” he said. “You can do prescription burning in chaparral and have essentially no impact on Santa Ana wind-driven fires.” As far as he can tell, based on information from CalFire, the Eaton Fire started on an urban street.
While it’s likely that climate change played a role in amplifying the drought, it’s hard to say how big a factor it was. Patrick Brown, a climate scientist at the Breakthrough Institute and adjunct professor at Johns Hopkins University, published a long post on X outlining the factors contributing to the fires, including a chart of historic rainfall during the winter in Los Angeles that shows oscillations between very wet and very dry years over the past eight decades. But climate change is expected to make dry years drier in Los Angeles. “The LA area is about 3°C warmer than it would be in preindustrial conditions, which (all else being equal) works to dry fuels and makes fires more intense,” Brown wrote.
