Catching up with David Funk of Zero Emissions Northwest on policy whiplash and complications from tariffs.

With previously obligated funding for programs backed by the Inflation Reduction Act and the Infrastructure Investment and Jobs Act beginning to be reinstated, individuals and businesses are fearing whiplash as they restart programming against a backdrop of increasing political and economic uncertainty.
Take David Funk, the founder and president of Zero Emissions Northwest, which works to connect farmers and small business owners in the rural Pacific northwest with grant opportunities through the Department of Agriculture’s Rural Energy for America Program. The last time I talked with Funk, he had just laid off his three employees in the wake of President Trump’s day one freeze on funds granted under the IRA and infrastructure law. Without these federal grants, Funk had no money to pay himself or his employees, and a number of his customer’s energy efficiency projects — things such as solar installations, upgraded appliances, or heat pumps — hung in limbo.
Last month, the USDA restored funding for Rural Energy for America, as well as a number of other related programs, so long as project applicants “remove harmful DEIA and far-left climate features” from their project proposals. I caught up with Funk today about what ZEN has been up to since its funding has been reinstated, and how his organization and customers are reacting to a moment when nearly everything seems to be in flux. Our conversation has been edited for length and clarity.
So we last spoke at the very end of January, soon after Trump’s funding freeze went into effect and you had to lay off your employees. What’s happened with ZEN since then?
About a month later, I was able to bring [my employees] back because of a Washington state unemployment program called SharedWork. [The program allows employees to work on a part-time basis while also collecting unemployment to help compensate for lost wages.] But I didn’t have the cash flow to pay everybody for this indefinite amount of time with our major contract being frozen. And then about a month after that, you get this press release from the USDA that they have reauthorized the Rural Energy for America program and several other ones. And maybe three days after that, we got our check.
Simultaneously, we won an additional contract with the USDA called the Energy Audit and Renewable Energy Development Assistance Program. It allows us to work with agricultural producers and do more comprehensive energy audit work, so sitting down with a farmer in a more consultative approach to say, here’s where you’re using energy today, and here’s some easy, low-hanging fruit that we can work on.
What were the repercussions for your staff and for your customers of that two-month funding freeze?
It’s a lot of wasted effort. For the first month when this was happening, I was trying to keep the ship afloat, trying to figure out how to take care of my employees, communicating so much uncertainty to my customer base, and recognizing that there’s a very wide spectrum of political viewpoints with my customer base. It takes so much delicate wordsmithing to write an email to all of my customers to say, this is the news that came out this week and this is how I’m interpreting this.
Now what we’re doing is calling our customers being like, “let’s restart your project, grants are getting paid.” I fully anticipate, as we’re going through our long tail of customers, that some projects are just going to stall out and never happen, which is disappointing. People’s attention goes elsewhere. Farmers are not really interested in taking on more debt than they need to. If you don’t have the cash reserves, and your commodity prices are low, and you’re looking at increased fertilizer costs and everything, there’s a limited window to make this all happen, and the uncertainty and the volatility in the economy has increased. So I anticipate there are going to be some people going, this was a great idea nine months ago, but not a good business decision right now.
Did you have to — or are you planning to — change any of the language in your grant applications to remove any mention of climate benefits or equity?
No, we haven’t. And largely, that’s because what we’re deploying, it’s technical, it’s hardware, it’s insulation. There’s no DEIA component. We’re trying to help businesses control their energy and financial future, and energy efficiency is apolitical. So if you can find an opportunity that has a good payback period, it’s a good use of your dollars. It just needs to make financial sense.
What we do focus on is energy production, energy dominance. We use a lot of that language because especially in our communities, resilience is important.
What other unknowns are making this a tricky business environment for your customers at the moment?
We’re looking at solar and going, what’s it going to cost? It’s so hard to plan for all of this stuff, because the supply chain is becoming a risk. I’ve had contractors after tariffs are announced go, “let me call my vendor and reprice this.” So that just doesn’t make anybody feel super comfortable. We know that the [clean electricity] tax credits are going to probably be on the negotiating table this summer. And I don’t want anybody to start a project that might not finish this year because who knows what the tax credits are going to be. So I can absolutely see some people just say, I’m not going to do anything right now. I’ll wait it out, or I’ll focus on my core business of farming.
Farmers are no strangers to the turbulence of Trump’s trade policies, as they were also hit hard after Trump imposed tariffs on China in his first administration. How are Trump’s latest tariffs, as well as China’s retaliatory tariffs, impacting your customers?
Under the first Trump administration, there was a bailout for agriculture. Under this administration, there might be a bailout for agriculture, but it’s nowhere near compensating these farmers enough for losing out on the commodity prices. If China stops buying wheat, that might be $1 off the wheat price, which is going to be a lot more significant than a $50,000 bailout that a farmer might get to compensate them for that.
Already the supply chain was pretty challenged through COVID, and now with tariffs, if you have a mission-critical piece of equipment — whether it’s irrigation or electrical or a tractor — and a part is manufactured abroad, and tariffs are throwing that supply chain into chaos and something breaks, how quickly can you get it? And what are you going to have to do to harvest your crop?
I don’t see many things going in the right direction. And I think that’s the common sentiment, which is, where’s the good news? It’s definitely going to be a lot clearer in 12 months after we get through a growing season.
How are you thinking about the future of ZEN given the general atmosphere of uncertainty and changing priorities?
As a small company, this funding pause really highlighted that a lot of our eggs are in one basket. What happens in the future if the USDA is not here and our contract goes away? We are trying to find new markets and find new programs and new opportunities. One of the areas that we’re looking at is really schools, because we’ve built up a strong professional reputation in rural areas — well, rural schools need help too. And you know, when I think about rural communities, it’s impossible not to think about resiliency. I think resiliency is always going to be a winning argument if you can make the numbers work.
Probably because we provide services to rural agricultural communities, many of which voted largely in favor of this president, we are benefiting from that favoritism. But there are so many programs that I think are being paused or unjustly canceled, and a lot of good work is being stalled out or just terminated. So it’s very bittersweet. And while you know we’re on the winning team right now, I think overall it’s a net loss.

The sale of Ravenswood Generating Station closed at the end of January.
New York City’s largest fossil fuel-fired power plant has changed hands. The Ravenswood Generating Station, which provides more than 20% of the city’s generation capacity, was sold by its former parent company LS Power to NRG, an energy company headquartered in Texas that owns power plants throughout the country.
It’s not yet clear what this means for “Renewable Ravenswood,” the former owner’s widely-publicized plans to convert the site into a clean energy hub. Prior to the sale, those plans were hanging by a thread. NRG did not respond to detailed questions about whether it will abandon or advance that vision.
“Ravenswood has been an important part of powering New York City for decades, and we recognize how much the facility matters to the surrounding community and the region,” a spokesperson for the company told me in an email. “We’ve begun engaging with community stakeholders and look forward to continuing those conversations in the months ahead. Our leadership team is carefully reviewing all relevant information and is taking a thoughtful, measured approach to any future decisions.”
Ravenswood is made up of four generating units: a natural gas combined cycle plant built in 2004, and three steam generators built in the 1960s that run mostly on natural gas, though sometimes also on oil. The plant is responsible for a sizable chunk of the city’s climate footprint. In 2023, the most recent year for which data is available, the plant emitted nearly 1.3 million metric tons of CO2, or about 8% of the city’s emissions from electricity production.
The Renewable Ravenswood concept was largely celebrated by the surrounding community, which includes two of the largest public housing projects in the country and suffers from disproportionately high rates of chronic respiratory diseases like asthma. The plan, which a local subsidiary of LS Power called Rise Light and Power proposed in 2022, entailed replacing the plant’s three 1960s steam generators with a combination of offshore wind, batteries, and renewable energy delivered from upstate New York via new power lines.
By last year, however, the plan was increasingly looking like a distant dream. Its centerpiece was a proposed offshore wind farm called Attentive Energy, but the project has been on ice since 2024, with little chance of moving forward under the Trump administration. This past November, New York regulators rejected a proposed transmission line that would have connected Ravenswood to a hypothetical future offshore wind development, primarily because there was no longer any such development in progress. Earlier this week, state energy regulators delivered yet another blow to potential offshore wind development when they decided not to solicit offers from for new projects to enter the state’s energy market.
Battery development has also had a rocky few years in New York State, which has affected Ravenswood’s transition. Rise Light and Power initially proposed building a 316-megawatt battery project on the site in 2019, but it has yet to break ground. The former CEO, Clint Plummer, previously told me that the company was waiting on New York State regulators to open up their anticipated battery solicitation, which would enable the project to bid into the New York energy market, before building the project. That solicitation opened last July, but it’s unclear whether the company submitted a bid. NRG did not respond to a question about this.
NRG first announced its plans to buy a fleet of natural gas plants — 18 in total — from LS Power in May 2025. Ravenswood was not mentioned in the press release or investor materials, however. “We're acquiring these assets at a significant discount to new build cost, at an attractive valuation, and at the strategically opportune time to be adding high-quality, difficult-to-replicate resources into our portfolio as the sector enters into a period of sustained demand growth,” NRG’s CEO Lawrence Coben told investors at the time.
The purchase was subject to regulatory approval and officially closed a few weeks ago, on January 30. Documents filed with the Securities and Exchange Commission confirm that Ravenswood was part of the deal. Documents filed with the New York Public Service Commission describe the terms in more detail, but they do not mention the proposed transition of the site to a clean energy hub.
Local officials, community groups, and tenant associations were deeply involved in fleshing out the Renewable Ravenswood vision. The Queens Borough President worked with the former owner on a multiyear report called “Reimagine Ravenswood,” released last summer, based on extensive engagement with the community, including public workshops, focus groups, interviews with local leaders, and a community survey. The report is evidence of high hopes the community has for the site’s transition, describing the potential to create jobs, expand public space, and generally increase investment in the neighborhood.
I reached out to many of the local elected officials and community groups that have publicly supported Renewable Ravenswood to ask if they were aware of the sale and whether NRG had made any commitments in regard to the transition plan. Just one responded. State Senator Kristen Gonzalez’s office told me they were aware of the sale, but declined to comment further.
Heron Power and DG Matrix each score big funding rounds, plus news for heat pumps and sustainable fashion.
While industries with major administrative tailwinds such as nuclear and geothermal have been hogging the funding headlines lately, this week brings some variety with news featuring the unassuming but ever-powerful transformer. Two solid-state transformer startups just announced back-to-back funding rounds, promising to bring greater efficiency and smarter services to the grid and data centers alike. Throw in capital supporting heat pump adoption and a new fund for sustainable fashion, and it looks like a week for celebrating some of the quieter climate tech solutions.
Transformers are the silent workhorses of the energy transition. These often-underappreciated devices step up voltage for long-distance electricity transmission and step it back down so that it can be safely delivered to homes and businesses. As electrification accelerates and data centers race to come online, demand for transformers has surged — more than doubling since 2019 — creating a supply crunch in the U.S. that’s slowing the deployment of clean energy projects.
Against this backdrop, startup Heron Power just raised a $140 million Series B round co-led by Andreessen Horowitz and Breakthrough Energy Ventures to build next-generation solid state transformers. The company said its tech will be able to replace or consolidate much of today’s bulky transformer infrastructure, enabling electricity to move more efficiently between low-voltage technologies like solar, batteries, and data centers and medium-voltage grids. Heron’s transformers also promise greater control than conventional equipment, using power electronics and software to actively manage electricity flows, whereas traditional transformers are largely passive devices designed to change voltage.
This new funding will allow Heron to build a U.S.manufacturing facility designed to produce around 40 gigawatts of transformer equipment annually; it expects to begin production there next year. This latest raise follows quickly on the heels of its $38 million Series A round last May, reflecting hunger among customers for more efficient and quicker to deploy grid infrastructure solutions. Early announced customers include the clean energy developer Intersect Power and the data center developer Crusoe.
It’s a good time to be a transformer startup. DG Matrix, which also develops solid-state transformers, closed a $60 million Series A this week, led by Engine Ventures. The company plans to use the funding to scale its manufacturing and supply chain as it looks to supply data centers with its power-conversion systems.
Solid-state transformers — which use semiconductors to convert and control electricity — have been in the research and development phase for decades. Now they’re finally reaching the stage of technical maturity needed for commercial deployment, driving a surge in activity across the industry. DG Matrix’s emphasis is on creating flexible power conversion solutions, marketing its product as the world’s first “multi-port” solid-state transformer capable of managing and balancing electricity from multiple different sources at once.
“This Series A marks our transition from breakthrough technology to scaled infrastructure deployment,” Haroon Inam, DG Matrix’s CEO, said in a statement. “We are working with hyperscalers, energy companies, and industrial customers across North America and globally, with multiple gigawatt-class datacenters in the pipeline.” According to TechCrunch, data centers make up roughly 90% of DG Matrix’s current customer base, as its transformers can significantly reduce the space data centers require for power conversion.
Zero Homes, a digital platform and marketplace that helps homeowners manage the heat pump installation process, just announced a $16.8 million Series A round led by climate tech investor Prelude Ventures. The company’s free smartphone app lets customers create a “digital twin” of their home — a virtual model that mirrors the real-world version, built from photos, videos, and utility data. This allows homeowners to get quotes, purchase, and plan for their HVAC upgrade without the need for a traditional in-person inspection. The company says this will cut overall project costs by 20% on average.
Zero works with a network of vetted independent installers across the U.S., with active projects in California, Colorado, Massachusetts, Minnesota, and Illinois. As the startup plans for national expansion, it’s already gained traction with some local governments, partnering with Chicago on its Green Homes initiative and netting $745,000 from Colorado’s Office of Economic Development to grow its operations in Denver.
Climactic, an early-stage climate tech VC, launched a new hybrid fund called Material Scale, aimed at helping sustainable materials and apparel startups navigate the so-called “valley of death” — the gap between early-stage funding and the later-stage capital needed to commercialize. As Climactic’s cofounder Josh Fesler explained on LinkedIn, the fund is designed to cover the extra costs involved with sustainable production, bridging the gap between the market price of conventional materials and the higher price of sustainable materials.
Structured as a “hybrid debt-equity platform,” the fund allows Climactic’s investors to either take a traditional equity stake in materials startups or provide them with capital in the form of loans. TechCrunch reports that the fund’s initial investments will come from an $11 million special purpose vehicle, a separate entity created to fund a small set of initial investments that sits outside Material Scale’s main investing pool.
The fashion industry accounts for roughly 10% of global emissions. “These days there are many alt materials startups that have moved through science and structural risk, have venture funding, credible supply chains and most importantly can achieve market price and positive gross margins just with scale,” Fesler wrote in his LinkedIn post. “They just need the capital to grow into their rightful commercial place.”
Clean energy stocks were up after the court ruled that the president lacked legal authority to impose the trade barriers.
The Supreme Court struck down several of Donald Trump’s tariffs — the “fentanyl” tariffs on Canada, Mexico, and China and the worldwide “reciprocal” tariffs ostensibly designed to cure the trade deficit — on Friday morning, ruling that they are illegal under the International Emergency Economic Powers Act.
The actual details of refunding tariffs will have to be addressed by lower courts. Meanwhile, the White House has previewed plans to quickly reimpose tariffs under other, better-established authorities.
The tariffs have weighed heavily on clean energy manufacturers, with several companies’ share prices falling dramatically in the wake of the initial announcements in April and tariff discussion dominating subsequent earnings calls. Now there’s been a sigh of relief, although many analysts expected the Court to be extremely skeptical of the Trump administration’s legal arguments for the tariffs.
The iShares Global Clean Energy ETF was up almost 1%, and shares in the solar manufacturer First Solar and the inverter company Enphase were up over 5% and 3%, respectively.
First Solar initially seemed like a winner of the trade barriers, however the company said during its first quarter earnings call last year that the high tariff rate and uncertainty about future policy negatively affected investments it had made in Asia for the U.S. market. Enphase, the inverter and battery company, reported that its gross margins included five percentage points of negative impact from reciprocal tariffs.
Trump unveiled the reciprocal tariffs on April 2, a.k.a. “liberation day,” and they have dominated decisionmaking and investor sentiment for clean energy companies. Despite extensive efforts to build an American supply chain, many U.S. clean energy companies — especially if they deal with batteries or solar — are still often dependent on imports, especially from Asia and specifically China.
In an April earnings call, Tesla’s chief financial officer said that the impact of tariffs on the company’s energy business would be “outsized.” The turbine manufacturer GE Vernova predicted hundreds of millions of dollars of new costs.
Companies scrambled and accelerated their efforts to source products and supplies from the United States, or at least anywhere other than China.
Even though the tariffs were quickly dialed back following a brutal market reaction, costs that were still being felt through the end of last year. Tesla said during its January earnings call that it expected margins to shrink in its energy business due to “policy uncertainty” and the “cost of tariffs.”
