Plus a note on batteries.
Rooftop solar is not like other types of consumer technology. Even though the end result is having a bunch of electrical equipment installed on the roof of your home, the process of getting solar is more like doing a bathroom renovation than buying a flat screen TV. To get the results you’re looking for, the most important decisions you’ll make are not the brand or model of the panels, but rather who you hire for the job, the size of your system, and how you finance it.
There’s a bunch more choices you’ll have to navigate along the way, and it’s easy to get overwhelmed. One expert I spoke with told me that sometimes the customers who are the most excited about getting solar end up bailing, the victims of decision fatigue.
We created this guide to save you from that fate. So take a deep breath, take my hand, and let’s walk down the metaphorical hardware store aisle and get you the rooftop solar solution you’re dreaming of.
Roger Horowitz is the director of Go Solar programs at Solar United Neighbors, a national nonprofit that serves as an unbiased resource for homeowners interested in solar. Horowitz manages and provides technical support to the company’s Solar Help Desk team.
Tony Vernetti is a senior trainer at Enphase Energy, a company that produces inverters, batteries, and EV chargers, where he trains solar sales and installation teams. Before joining Enphase in 2020, Vernetti spent 12 years working for rooftop solar companies in California.
Nate Bowie is the vice president of residential sales at ReVision Energy, an employee-owned solar company operating throughout northern New England. Bowie has been selling solar for ReVision for 15 years.
While the actual installation of the system should only take one to two days, the entire process from initial outreach to grid connection takes two to four months on average, according to Solar United Neighbors.
Example: The highest rated solar panels for 2024 according to EnergySage.com are SunPower's M-Series 440 watt model. If you install 20 of these, the system will be capable of generating 8,800 watts, or 8.8 kilowatts in direct sun.
When you start searching for information about solar on the internet, you might come across advertisements or commercials promoting free solar panels. There is no such thing. These ads are typically schemes to collect your personal data and sell it to solar companies looking for leads, and the federal government is starting to
crack down on them.
It is possible to install solar with zero up-front costs if you lease the system or take out a loan to finance it, but in both cases you will still owe monthly payments. It is also rare that anyone is able to offset 100% of their utility bill. You can get close, but you will likely still owe at least a connection fee to your utility company.
Most homeowners in the U.S. can benefit from installing solar as long as local energy policies are favorable. Placing the panels on a south-facing roof is optimal, but not necessary. If your panels face due west, you’ll only lose about 10% of potential generation, according to Vernetti. “They still produce a ton of energy. They’re still very effective. It's just a little bit less than if they're facing south,” he said. An east-facing roof is also viable in most cases.
You don’t have to worry about shoveling snow off the roof or anything like that. But like any other electronic devices, solar panels, inverters, and batteries can break or malfunction, and your system may require servicing at some point. Pay close attention to your warranties (more on that later). If you lease the system, you do not have to worry about this as much because the third-party owner will be responsible for maintenance.
In order to design a system that meets your needs and budget, solar companies will ask for a copy of your most recent electricity bill or, ideally, your annual energy consumption history. Make sure you have this information handy before you reach out for quotes.
Some utilities include your annual energy consumption, broken out by month, at the bottom of your electric bill. If you don’t see it, you should be able to log into your utility account online and download either your statements from the past year or a spreadsheet of your monthly electric meter readings.
In most of the U.S., you will find you have the option either to lease your solar panels or buy them outright. You don’t have to decide which way you want to go before you get started, but it’s helpful to think through the pros and cons of each.
Heatmap Recommends leasing if: You’re fairly certain you’ll keep your house for the next 15 to 20 years; you can’t afford the system outright, but you don’t want to take out a loan; your priority is to generate clean energy and reduce emissions, but you don’t want to spend too much time figuring out what you want or worrying about the system’s maintenance.
Heatmap Recommends buying if: You have the cash in hand; you might sell your house in the next 20 years; you know you want to have control over the details of your project.
The federal government offers a 30% tax credit for solar installations (and batteries) that covers parts and labor. It can significantly reduce the cost of getting solar, even if you don’t have a lot of tax liability in the year that you install the system. The credit will roll over to subsequent tax years.
Example: If you spend $25,000 installing solar in 2024, you’ll be eligible to take $7,500 off your federal income tax bill. If you only owe $3,000 in federal taxes in 2024, you’ll get $3,000 back and will be eligible to claim the remaining $4,500 for the 2025 tax year. If in 2025 you only owe $3,000 again, you can claim the remaining $1,500 in 2026.
Additional tax credits and rebates may also be offered by your state energy office, city, or utility. Contractors should be able to help you figure out what you’re eligible for, and you can wait to talk to them to learn more. However, incentives change frequently, and contractors don’t always keep up, so you might want to review the options in your area independently.
It will also be helpful to understand your state’s net metering policy, as that will determine how quickly your investment in solar will pay off and may also dictate how big your system can be. Some states, like New Jersey, also allow homeowners to generate additional income through the sale of solar renewable energy credits, or SRECS.
Where to look for more information:
One of the worst things that could happen is you install rooftop solar panels, and then later find out you have a leak or some other problem with your roof. “Removal and replacement of an array for a reroof is expensive and could significantly impact the owner’s return on investment,” Bowie told me. While metal roofs last a very long time and are unlikely to need a replacement, asphalt shingle roofs generally have a useful life of 25 to 30 years, Bowie said. You should be fine if your roof is less than 10 years old, but if not, you may need some roofing work done before your solar panels are installed.
If you don’t know how old your roof is, Vernetti recommended having a roofing contractor inspect it. He added that there’s varying opinions on this, with some solar experts recommending replacement if the roof is only 5 years old. “In my opinion, scrapping a 5 year old roof is wasteful and goes against the goal of sustainability,” he said.
“A good solar contractor will help evaluate the roof conditions and should recommend replacement when necessary, even if it is just to replace the roof on the roof plane where the solar panels will go,” said Bowie.
Solar contractors range from local mom and pop shops, to regional providers like ReVision Energy, which operates in multiple states in the Northeast, to national companies that install across the country like Sunrun and Sunnova.
“The advantage of going with a large company is that they have the ability to offer financing the smaller companies might not be able to. With a regional company, you can actually walk to their office and knock on the door and talk to somebody if you want to,” said Vernetti.
Heatmap Recommends: Contact at least one local company and one national company to get a good sense of your options. Always get at least three quotes!
If you are calling installers directly, here are some tips for what you should ask for or look for in a quote. (If you are using an online resource like EnergySage that finds quotes for you, use the following to help you ask follow-up questions or refine the proposals.)
A few questions you should ask:
One of the first questions an installer might ask you is how big you want the system to be. You may want to see quotes for multiple options in order to compare them. Options include:
Heatmap Recommends: Oversize your system if you can afford it.
Why?
Exceptions:
Most installers will include a financing option in their quote. Horowitz noted that some installers advertise very low interest rates that are below market rate. They are typically able to do this by paying a “dealer fee” to the bank, which they incorporate into the price of your installation — in other words, if your interest rate seems too good to be true, the total cost of your installation will likely be higher than it otherwise would be. To get a better sense of the true cost, ask for quotes both with and without financing options.
Adding energy storage, a.k.a. a battery, to your solar array can add another 10 grand or more to the project cost. But there are a few reasons it might be worth it:
In conclusion, if you just want back-up power, any battery that’s large enough to power your essential systems should do. If you want to pay off the investment, look into time-of-use rates. If you want your investment to go further for decarbonization, ask your contractor if there are local grid services programs available, and if any of their products are compatible.
After you get a few quotes, you’re going to want to spend some time comparing them, asking questions, and potentially soliciting additional quotes with variations on the system. If you’re feeling overwhelmed or you don’t have the time or patience to sort through the details on your own, you can also call the Solar United Neighbors Help Desk, which offers a free quote review service.
The most important number on the quote is the price per watt, not the total system cost. That is the number you should be comparing between different installers, as the quotes may be for differently sized systems.
You should also compare the annual bill savings. If two different companies quote you significantly different savings for systems that are roughly the same size, one of them has likely done a more detailed analysis of your roof than the other.
“It doesn't matter what module you have, from which manufacturer, or what inverter you have. There really is no difference in what your system can produce if it's the same size,” said Bowie.
Lastly, if the quote is for a solar lease, or includes a financing option, look at the monthly payments.
Every installer has certain brands and types of equipment they work with. Our expert panel agreed that it’s important to look at the brand names the installer is offering for the solar panels, inverters, and batteries, and to make sure they are from reputable companies that have been around for at least five years — even if it means paying more. A quick internet search of the top 10 residential solar panel brands should give you a taste of what those companies are.
“It is definitely worth paying a little bit extra to have really good equipment,” Vernetti said.
You may also see installers advertise that they offer “Tier 1” solar panels. That means the manufacturer has been designated “bankable” by Bloomberg New Energy Finance. The designation is more related to finance than product quality, but many solar companies use it as a rough proxy for reliability.
That being said, don’t get too bogged down in comparing solar brands.
“There's not a huge difference, typically, between one solar panel and the next of the Tier 1 manufacturers,” said Bowie. “A lot of solar companies will maybe offer one or two different manufacturers, and then maybe beyond that one or two different sizes.”
When it comes to inverters, you do want to pay attention to whether your quote includes string inverters, microinverters, or power optimizers. In a system with a string inverter, your panels will all be wired to one central inverter. This is generally the cheapest option, but it is less durable and may need to be replaced, said Vernetti, whose employer, Enphase, is the leading producer of microinverters. String inverters can also limit the output of your system if part of the roof gets more shade.
The other two options are more expensive but get around the issue with shade. A system with power optimizers is similar to one with a string inverter, but each panel will also have a small device attached to it that regulates the output and maximizes your system’s performance. By contrast, microinverters are small inverters attached to each individual panel. Both of these options also allow you to monitor each panel’s performance.
Bowie said the two were comparable in terms of performance and price. A key consideration, he said, is that your choice of inverter can begin to lock you into using the same brand of equipment on other home upgrades you might do down the line. “If you're an EnPhase customer, you're likely going to be going down the track of an EnPhase battery storage system,” he said. “Whether the customers know it or not, they're kind of being pushed down a path towards this manufacturer for more things in their home, like batteries, whole home controls, electric vehicle charging."
Your quote should provide information about warranties offered by the manufacturers of the panels, inverters, and batteries, as well as by the installation company. 25-year warranties are standard, but the details vary by installation company and by manufacturer. For example, your inverters may have a 25-year warranty, meaning you can get replacement inverters for free if any of them fails within that time period — but if you don’t have a warranty on labor, it could cost you several hundred dollars to get them installed.
“It's really important for customers to read the fine print and to talk with their local solar company who is quoting the system for them to uncover what the warranties mean,” said Bowie.
This is especially important if you are installing batteries. Ask your installer about both the equipment warranty and their policy is for servicing the equipment.
Most solar installers offer financing options. Your quote should include the name of the lender the installer works with, the down payment, monthly payment, financing term, and interest rate. However, you may find a better deal elsewhere. Horowitz noted that installers like using their own financing companies because it speeds up the sales process — they can approve you for a loan just by putting in your social security number, and sell it to you at the same time as the contract. But you may find a better deal elsewhere.
“Talk to your bank, talk to your credit union, look at home equity lines of credit, see what other options you have out there, and if those have lower interest rates or better payment terms,” said Horowitz. “You are not required to use their finance.”
After you’ve found an installer, settled on a system design, and secured financing, all that’s left to do is sign your contract. Then, you wait. Your installer will have to obtain permits from your city, county, or state, as well as an interconnection agreement with your utility.
One way to try to minimize the wait time is by working with an installer with lots of local experience. They’ll be better equipped to navigate the permitting process. For example, if you want Tesla solar panels but Tesla hasn’t done many installations in your community, it may take longer for the company to get through this stage.
After these two steps are complete, the solar company will reach out to you to schedule the installation, which should only take a few days.
After the system is installed, you may have to wait for a final inspection from your utility or a verified third party for permission to operate the system.

A list of terminated grants obtained by Heatmap contains a number of grants that will cost jobs and revenue in Republican-led states.
The Trump administration terminated billions in climate and clean energy grants on Wednesday, in what appears to be yet another act of retribution against Democrats over the government shutdown. White House budget director Russell Vought announced on X that “nearly $8 billion in Green New Scam funding to fuel the Left's climate agenda is being cancelled,” noting that the projects were in 16 states, all but two of which — Vermont and New Hampshire — have Democrats in their governor’s mansion. A Department of Energy release published late last night further clarified that it was terminating 321 awards supporting 223 projects, with a total closer to $7.5 billion.
But a list of the 321 canceled grants that the Department of Energy sent to Congress, obtained by Heatmap, tells a different story. While much of the funding was awarded to blue state-based companies, the intended projects would have benefitted communities elsewhere, including in Texas, Florida, and Louisiana.
The list identifies the grants by their award numbers, and includes information on the DOE office overseeing the grant, the recipient name, and state. The document does not specify the project names, the programs under which they were awarded, or the amounts awarded.
That leaves a lot of open questions about the true impact of the terminations. It’s unclear, for instance, whether the $7.5 billion price tag the Department of Energy assigned to the cancellations is an estimate of the total amount awarded or the unspent remainder still in the agency’s coffers. Five of the listed projects, worth nearly $900 million, were already announced as terminated in an earlier round of cuts back in May.
Many of the projects listed have signed contracts with the government, are already well underway, and have spent at least some of their award. For example, the Northeast Energy Efficiency Partnerships has already published copious educational materials related to its community-driven transportation plan for the Northeast, a project supported by one of the terminated grants.
The list does seem to confirm that blue state grants were the hardest hit, with 79 award cancellations in California, 41 in New York, 34 in Colorado (Secretary of Energy Chris Wright’s home state), 33 in Illinois, and 31 in Massachusetts.
But when I began looking up projects by their award number, I found that many would actually have benefitted Republican strongholds. Take, for example, Moment Energy, a Delaware-based company that was awarded $20 million by the Office of Manufacturing and Energy Supply Chains to build the first certified manufacturing facility in the United States producing battery energy storage systems from repurposed electric vehicle batteries. The plant was set to be built in Taylor, Texas, creating 50 construction jobs and 200 new permanent positions. After receiving the Energy Department’s stamp of approval, the company raised a $15 million Series A funding round in January to help finance the plant.
Also listed are a $10 million grant for Carbon Capture Inc, a California-based company, to conduct an engineering study for a direct air capture plant in Northwest Louisiana, and a $37 million grant to New York-based Urban Mining Industries to build one of its low-carbon concrete manufacturing plants in Florida. Linde, the global industrial gas company based in Connecticut, had $10 million to build hydrogen fueling stations for heavy duty trucks in La Porte, Texas, clawed back. BKV, a Colorado-based natural gas company set to study the transportation of captured CO2 by barge throughout the Gulf Coast region, also had its $2.5 million grant canceled.
In addition to hurting investments and jobs in Republican states, the Department of Energy’s cancellations also target some unlikely victims. The list names 16 grants for General Electric, including 11 for GE Vernova, the company’s manufacturing arm, which produces natural gas turbines and components for wind energy generation; many of those awards were for wind technology research projects. The agency also canceled 24 grants for the Institute for Gas Technology and the Electric Power Research Institute, the research arms of gas and electric companies’ two biggest trade groups, respectively. Several of these awards funded research projects into carbon capture and storage.
Also on the list was a more than $6.5 million grant for a controversial study to retrofit the Four Corners coal plant in New Mexico with carbon capture equipment. The plant is currently scheduled to close in 2031.
Back in May, Wright promised Congress his agency’s review of Biden-era climate funding would be over by the end of the summer. “Certainly in the next few months, by the end of this summer — hopefully before the end of this summer — we will have run through all of the four or 500 large projects that are currently in the pipeline at the DOE,” he said during a House Appropriations Committee hearing.
As reported yesterday by Bloomberg, two regional Hydrogen Hubs in California and the Pacific Northwest — projects awarded funding from the Bipartisan Infrastructure Law to develop full hydrogen production and consumption ecosystems — are on the list. That leaves the agency’s intentions for the remaining five hubs scattered throughout the Midwest, Midatlantic, Appalachia, the Great Plains, and Texas unclear. And while the list includes a few smaller grants for early-stage Direct Air Capture Hubs, it is still a mystery whether the Department of Energy plans to support the two more advanced direct air capture projects in Louisiana and Texas that were selected for $1.2 billion under the Biden administration.
On a major energy acquisition, carbon cycle cash, and a cheaper EV
Current conditions: Hurricane Imelda hit Bermuda as a Category 2 storm • Storm Amy, the first named UK storm of the season, will bring heavy rains and wind to Scotland, England, and Wales on Friday • Sudan’s Ministry of Agriculture declared a state of emergency this week after the Nile River rose to record levels.
The Department of Energy said on Wednesday that it is terminating 321 grants supporting 223 projects, cutting a total of more than $7.5 billion in funding for clean energy projects. While the Department has not yet specified what the awards were, Office of Management and Budget Director Russ Vought posted to social media yesterday that the canceled projects were located across 16 Democrat-led states. An administration official told Bloomberg that at least two of the projects in question were hydrogen “hubs” under development in California and the Pacific Northwest. The cuts come on top of $13 billion in climate funds that had not yet been dedicated to specific projects that the Department of Energy said it would “return” in late September, as instructed by the reconciliation bill.
The Department of Energy has left the recipients of billions in obligated funds for climate projects in limbo since Trump took office. Secretary of Energy Chris Wright said the agency was “reviewing” the awards in May. He testified in Congress that his office would make a decision about many of them by the end of the summer, but this week’s terminations — amid the government shutdown — are the first announcement the agency has made since an initial batch of cuts at the end of May.
The Trump administration said Wednesday that it is putting $18 billion in funding for New York City transit projects on hold while it investigates violations of a rule barring diversity considerations in hiring that the Department of Transportation published on Tuesday. “The timing is, shall we say, noteworthy,” my colleague Matthew Zeitlin wrote on Wednesday, “not least because the Democrats’ two top congressional negotiators — Representative Hakeem Jeffries and Senator Chuck Schumer — are both from New York.” In a statement, Secretary of Transportation Sean Duffy blamed those two lawmakers for the shutdown, lamenting that thanks to them, “USDOT’s review of New York’s unconstitutional practices will take more time.”
Blackrock-owned Global Infrastructure Partners, an investment fund, is in talks to buy energy developer AES for more than $38 billion in “what would be one of the largest infrastructure takeovers of all time,” according to the Financial Times. AES owns utilities in Ohio and Indiana in addition to owning both conventional and renewable energy generation projects across the globe. The company is also the top supplier of renewable energy to corporate buyers in the world. AES stock jumped nearly 17% on Wednesday on the news.
A new report from the Union of Concerned Scientists found that residential customers in seven states that are part of the PJM Interconnection, an electricity market that covers the Mid-Atlantic and parts of the Midwest, are paying nearly $4.4 billion for transmission upgrades intended to deliver electricity to data centers. The finding is not a big surprise — PJM’s own Market Monitor has acknowledged that data center load growth is the primary factor driving up rates. But the report specifically analyzes the amount the whole ratebase is shelling out for transmission projects that only benefit a single customer. It recommends that the Federal Energy Regulatory Commission create a new customer class for such customers and require them to shoulder the cost alone.
Trump has slashed millions in grants for climate science research and plans to cut the federal government’s climate science funding and staff dramatically in next year’s budget. Stepping in to replace some of that lost cash is Schmidt Sciences, a philanthropy founded by former Google CEO Eric Schmidt. Schmidt announced Thursday that it’s committing up to $45 million over five years for research to advance understanding of some of the least-studied parts of the global carbon cycle. For example, one project will measure how much carbon dioxide the Southern Ocean absorbs from the atmosphere with the help of robotic sailboats that can collect data year-round, including during times when it’s too dangerous for research ships to operate.

Hyundai is cutting the price tag on its 2026 Ioniq 5 by nearly $10,000, and will continue to offer $7,500 off the 2025 model — equivalent to the now-expired federal tax credit. The 2026 Ioniq 5 base model will start at just $35,000, making it one of the cheapest EVs available in the U.S.
Some of the industry’s biggest names are joining forces to keep the momentum moving forward.
Climate tech funding has slowed in the face of federal government pushback — but it has certainly not stopped. As the administration has cranked up its hostilities against everything from electric vehicles to wind turbines, companies and investors are responding by getting strategic, forming new coalitions to map, fund, and shape progress in the absence of public support.
Last month I covered the launch of the Climate Tech Atlas, an interdisciplinary effort that includes venture capitalists, nonprofits, and academics working to map out the most salient climate tech opportunities and help guide external research and funding in the sector. There’s also the All Aboard Coalition, which unites big name investors to help plug the missing middle finance gap. Sector-specific investment vehicles are popping up too, like the Oneworld BEV fund, a partnership between major airlines in the Oneworld Alliance and Breakthrough Energy Ventures to advance the commercialization of sustainable aviation fuels. All three of these new initiatives were announced in September alone.
“We are in a unique moment right now,” Carmichael Roberts, a managing partner at BEV told me via email. “Over the past decade, the climate tech ecosystem has made enormous progress driving innovation across every sector of the economy. That puts us in the position to step back and ask first, what areas are still crying out for urgent innovation?”
This year has also seen a number of climate tech companies struggle at key points in their attempts to scale. Sodium-ion battery company Natron Energy shut down in September, while direct air capture leader Climeworks laid off 22% of its staff in May, citing “current macroeconomic uncertainty” and “shifting policy priorities where climate tech is seeing reduced momentum.” Another direct air capture company, Noya, shuttered this August, while the battery recycling company Li-Cycle filed for bankruptcy in May.
Other startups pursuing emerging technologies — from carbon capture to long-duration battery storage, advanced geothermal, and next-generation nuclear — are looking to avoid the same fate. But while federal funding from places such as the Department of Energy’s Office of Clean Energy Demonstrations and the Loan Programs Office once provided an avenue for financing capital-intensive demonstration plants, the Trump administration is now retracting funding, going so far as to cancel contracts with projects previously approved under Biden.
The Oneworld fund, announced in mid-September, is BEV’s first to focus on a specific theme and its first to be backed by an industry coalition. Members of the Oneworld Alliance — which include Alaska Airlines, American Airlines, British Airways, and Cathay Pacific — had already committed to using SAF for 10% of their fuel by 2030, while also “playing an active role in the development of SAF at commercial scale.” Now, with alliance members serving as limited partners in the venture fund, they’ll benefit from the technical and commercial expertise of one of the sector’s most influential VC firms.
When I asked the BEV team to what degree the current political and economic uncertainties were making partnerships like this more valuable, Eric Toone, another BEV managing partner, responded with a refrain I’ve become familiar with — that the firm only backs technologies that “can ultimately compete on their own merits.” Yet it’s undeniable that the federal government tore up its decarbonization agenda at a moment when many climate tech firms’ investments are almost ready for deployment, a stage when government support can make all the difference.
“Many promising SAF technologies already exist, but they are stuck between lab success and commercial scale,” Roberts told me. “This is the moment when they most need capital, technical rigor, and committed offtake to bridge that gap.” While the Trump administration did maintain and extend the tax credit for clean fuels, it also reduced the maximum credit amount for SAF from $1.75 per gallon to $1, while private funding for SAF production and distribution infrastructure remains inadequate.
Given this landscape and the urgency airlines face in meeting their clean fuel targets, Toone told me the firm is open to backing companies “that are further along than what a typical BEV fund might pursue.” And while sustainable fuels are the first technology to benefit from this type of thematic focus, Roberts said that BEV is already eyeing other sectors where it plans to apply this same funding model.
As of early September, the firm is also part of the All Aboard Coalition. This elite group of venture firms is aiming to raise a $300 million fund by the end of October that will match investments in later-stage venture rounds, filling a gap known in climate tech circles as the “missing middle.” Assembled by Chris Anderson, an entrepreneur and primary convener of the TED Talks conference — which has featured many inspiring climate visionaries — the group includes 14 members such as Khosla Ventures, Prelude Ventures, DCVC, Gigascale Capital, and Energy Impact Partners.
“One of the consequences of being in the front row seat at TED all these years is you get persuaded of certain things,” he told me. “And I definitely got persuaded that climate is the outstanding, major problem we really have to fix.”
The bulk of the capital for the coalition will come from outside investors, though some members will contribute as well, Anderson told me. The goal is to incentivize these hotshots to co-invest with each other, providing a one-to-one funding match if they do so.
“First-of-a-kind rounds seem out of reach for a lot of people in the chain,” Anderson explained, referring to the network of investors that must come together to help a company fund expensive new infrastructure. At this stage, its tech has progressed beyond the capital-light, early-stage rounds but is still considered too risky for traditional infrastructure investors to take on. Companies might be seeking $100 million or more from venture firms that are used to writing checks for orders of magnitude less. “Really the purpose of the fund is to create a collective belief that there is a pathway to getting these companies funded. If you have that collective belief, then it’s much easier for a lead investor to step forward and to pull a few other people in.”
Anderson acknowledged that a $300 million fund will not go “nearly far enough.”
“It’s a starter fund. It’s a proof of concept,” he told me. “The world needs to make a couple hundred of these bets at some point.”
Other coalitions, such as the Climate Tech Atlas, are working to steer the sector towards the best bets. This group — which also includes Breakthrough Energy Ventures, alongside others such as the nonprofit investment platform Elemental Impact, the consulting firm McKinsey, and Stanford University’s Doerr School of Sustainability — has mapped out the technological milestones it sees as the clearest pathways to decarbonization. The aim is to help investors, founders, policymakers and academics alike direct their energies towards the most relevant and investable opportunities, regardless of political headwinds.
“The scale at which the government participates in the development of these new technologies — or puts a thumb on the scale for technologies in particular — will vary,” Sonia Aggarwal, CEO of the policy firm Energy Innovation, which is also a member of the alliance, told me. “But certainly that has no real bearing on the fundamental fact that innovators are out there right now thinking about these grand challenges, and there are exciting new ideas for technologies that can get to that commercial scale in the coming years.”
And indeed, sometimes the most promising ideas can take shape in moments of deep uncertainty. Some of the biggest success stories of recent tech history — Uber, Airbnb, WhatsApp, and Square — all got their start during the 2008 financial crisis or its aftermath. “Some of the strongest companies and founders are building in uncertain times,” Dawn Lippert, founder and CEO of Elemental Impact, told me. “That’s very much what we see right now.”
These groups are far from the only private-sector actors coming together to help navigate industry headwinds. When the Environmental Protection Agency withdrew support for the most widely used U.S.-based carbon accounting model for estimating scope 3 emissions, leading emissions accounting platform Watershed partnered with Stanford University’s Sustainable Solutions Lab to launch an initiative that ensures continued access. And recognizing the difficulty that early stage climate tech startups face in securing insurance, the nonprofit GreenRE Coalition and the philanthropic funder Trellis Climate partnered to create a new type of bond tailored to the needs of climate tech startups.
Whether it will all be enough to accelerate or even sustain much-needed momentum in climate tech funding is impossible to predict. But at least the private sector seems to agree that, in this moment, good old teamwork is worth one heck of a try.
