On solar growth, Hornsea 4, and Rivian deliveries

Current conditions: The first cicada broods have begun to emerge in the Southeast as soil temperatures hit 64 degrees Fahrenheit • Hail and even snow are possible across parts of Spain today • Forecasters have identified a risk zone for tropical storm development in the Atlantic basin, with potential for the first named storm of the year to form by mid-May.
1. Global solar market expected to slow in 2025
The global solar market is expected to grow only 10% in 2025, down from 33% growth in 2024 and 87% growth in 2023, according to a new report by SolarPower Europe. The firm’s “most realistic scenario” accounts for the natural slowdown in development after a boom caused by high energy prices in 2022 and 2023, as well as the “uneven distribution of solar market growth” worldwide, with China accounting for 55% of the market share, lending to the dip in overall solar as it implements reforms this summer in how its renewables are priced and traded.
Speaking at the opening of the Intersolar 2025 conference in Munich on Wednesday, Abigail Ross Hopper, the CEO of the Solar Energy Industries Association, echoed some of the uncertainty expressed in SolarPower Europe’s report. “I don’t think any of us could be in this business if we weren’t optimistic,” she said, adding, “I think we’re going to weather through this storm, but it is going to be a bit rocky for a few years.” SolarPower Europe’s report, meanwhile, anticipates “likely” growth from 2 terawatts of global installed solar capacity at the end of 2024 to 7.1 terawatts of total installed capacity by 2030, which would meet “nearly two-thirds of the 11 terawatt renewable energy target set at COP28.” Under ideal conditions, solar could even quadruple capacity to more than 8 terawatts by the decade’s end. Read the full report here.
2. Orsted cancels 2.4-gigawatt offshore wind project in the UK, citing rising costs
The Danish energy company Orsted announced this week that it is canceling its Hornsea 4 offshore wind project in the UK due to rising supply chain costs and other “adverse macroeconomic developments,” the Wall Street Journal reported Wednesday. Hornsea 4 was expected to become one of the biggest offshore wind farms in the world, with a capacity of 2.4 gigawatts once it was completed. (Equinor’s recently paused Empire Wind I project, south of New York’s Long Island, would have had an 810-megawatt capacity by comparison.)
Orsted warned it would take a hit from the cancellation, with breakaway costs estimated to be between $533 million and $685 million. Nevertheless, “Orsted said the project no longer made economic sense, even with a contract to sell power at government-guaranteed prices for 15 years,” Bloomberg writes. Significantly, the canceled project will also hurt the UK’s efforts to add more renewables to its power grid.
3. ICYMI: Rivian lowered its delivery estimate by as much as 15% due to tariffs
Rivian beat Wall Street’s first quarter estimates, the automaker shared in its earnings letter to investors on Tuesday, but lowered its target for 2025 vehicle deliveries on account of tariffs, CNBC reports. Though the company builds all its electric vehicles in Illinois, “The current global economic landscape presents significant uncertainty, particularly regarding evolving trade regulation, policies, tariffs, and the overall impact these items may have on consumer sentiment and demand,” Rivian said by way of explanation. While it previously estimated it would deliver between 46,000 and 51,000 units in 2025, the revised outlook anticipates 40,000 to 46,000 deliveries. Last year, the company delivered just over 51,500 vehicles, Inside EVs notes.
The company also said it expects to take on “a couple thousand dollars” in additional expenses per vehicle due to the trade policies, though founder and CEO R.J. Scaringe said it’s not planning to increase the $45,000 starting price of the R2 as a result. Despite the continued uncertainty, Rivian said it still expects to achieve a “modest positive gross profit” in 2025.
4. Republicans sneak sale of public lands into reconciliation bill
Republicans on the House Committee on Natural Resources added an eleventh-hour amendment to their portion of the budget package late Wednesday night, calling for the sale of thousands of acres of public lands in Nevada and Utah. Introduced by Representatives Mark Amodei of Nevada and Celeste Maloy of Utah, the provision capitalized on longtime aspirations by Republicans to privatize Bureau of Land Management acreage in the West.
As I wrote on Wednesday, the Republicans’ maneuver, “which came at nearly midnight, left many Democrats and environmental groups deeply frustrated by the lack of transparency,” and critics had little time to comb through the extent of the proposal. While early reviews of the bill estimated the sell-off of about 11,000 acres of land, much of it apparently near cities — in keeping with Republican Senator Mike Lee’s aspirations to use BLM land for suburban sprawl — the Wilderness Society informed me last night that the accounting may end up as high as 500,000 acres or more. That’s consequential not just for public land advocates, but also because “turning over public lands to states — or to private owners — could ease the way for expansive oil and gas development, especially in Utah, where there are ambitions to quadruple exports of fossil fuels from the state’s northeastern corner,” I note in my piece. Moreover, “Reducing BLM land could also limit opportunities for solar, wind, and geothermal development.”
5. Thinning forests to reduce wildfire danger could also mitigate droughts: study
Thinning forests is a favorite idea of Republicans, who’ve rebuked blue states over forestry practices they claim exacerbate the dangers of wildfires. Now, a new study from researchers at the College of Agriculture, Biotechnology & Natural Resources at the University of Nevada, Reno looking at the hydrology of the Sierra Nevadas has found that the practice — along with prescribed fires — could also have potential upsides during drought years, including generating more mountain runoff.
According to the findings published in the journal Water Resources Research, water yields in forests thinned to densities closer to those of a century ago can be increased by 8% to 14% during drought years. That water would be “particularly valuable … to farmers and cities in central California and northern Nevada who rely on Sierra [Nevada] snowpack for much of their water supply,” according to a press release about the research. Significant flooding risks did not appear to increase with the water yields. As earlier researchers have found, however, the results of forest thinning treatments also depend on how, where, and to what extent the treatments are applied. Not all landscapes would necessarily benefit from such regimes. For example, while President Trump blamed the January fires in Los Angeles on poor forest management in California, the blazes were in chaparral, not in forests where thinning could be applied.

University of California, Riverside announced Wednesday that it is launching the nation’s only hydrogen-powered carshare program in a partnership with city and state agencies. Participants can rent Toyota Mirai sedans through a smartphone app and pay hourly rates competitive with Uber and Lyft fees.

A new front opens in the data center wars.
A series of lawsuits filed in federal court asks a big question – are data center moratoria constitutional?
In early August, data center developer DC Blox sued the city of Nashville in federal court to overturn a zoning moratorium stopping them from building a hyperscale facility adjacent to the city zoo. “The Data Center Moratorium, moreover, is a targeted attack against DC BLOX, in violation of federal constitutional protections,” the suit argued, claiming that it defied the corporation’s due process and equal protection rights.
Around the same time, another developer – Wixom Industrial One – filed a federal lawsuit against the city of Wixom, Michigan, to try and “invalidate the city’s illegal police power moratorium” blocking their data center.
These two cases were far from novel or the first of their kind, and they’re now a fresh front in the battle over hyperscale data centers. At least that’s what some who work on these cases say: In April, attorneys with the law firm Vorys published a “client alert” asserting “many moratoria may be vulnerable to statutory, procedural, and constitutional challenges.” The attorneys advised that constitutional arguments against moratoria “may be stronger where a government singles out data centers without a sound factual basis, treats similar land uses differently without a reasonable basis, or adopts a restriction driven more by political pressure than by defensible planning or regulatory objectives.”
Months later, according to court documents, the Vorys attorneys who authored the alert now represent real estate firm Thor Equities in a federal case against the Ohio city of Urbana, arguing the city’s decision to reject their data center project broke “fundamental protections” under the U.S. Constitution. (Vorys and Thor Equities did not respond to requests for comment.)
It’s unclear how many of these kinds of cases have been filed to date. Data on federal court cases is quite opaque. But legal experts and industry attorneys tell me we should expect them to be on the rise as developers seek whatever tools they can find to get projects built.
“Bringing a lawsuit like this is fairly cheap, something they can do at a relatively low cost, and imposes a real cost on local governments to defend themselves,” said Daniel Metzger, director of the Cities Climate Law Initiative at Columbia Law School’s Sabin Center. “The cases out there will be bellwethers. And if successful, there’ll be a lot more of them.”
What developers probably want looks a lot like Hill County, Texas, where an LLC proposing an $80 million data center project was stymied in May by the state’s first countywide moratorium. (It predated Governor Greg Abbott’s temporary freeze of data center development in Texas by three months.) Within a period of only a few weeks, the LLC sued and the county rescinded the pause on approvals. The case was dropped a month later. Local reports state the county had to afterwards pay the corporation $100,000 in legal fees – a drop in the bucket compared to what a drawn-out court battle would have cost the rural county.
Metzger said whether the companies will win these cases is ultimately not the point – their goal is to win a finished data center, not a judicial ruling. By filing expansive litigation in the national court system, a hypothetical developer can exhaust the coffers of a city or county with legal expenses that are chump change compared to would-be billions in private financing for compute infrastructure.
“These lawsuits may deter some local governments from taking steps to oppose data center development, just because of the cost it would impose on them to defend a lawsuit, even if they know they have a strong legal basis for the action they want to take.”
Those I spoke to in private practice about data center developers’ constitutional arguments agreed with Metzger’s assessment that it’s too early to tell whether the companies will win. Generally, they said, a city or county will win this kind of case if it demonstrates a rational basis for its decision-making and courts typically want to defer to governmental autonomy. The onus will be on the developers to prove a moratorium was meritless – that’s the due process challenge – or unfairly targeted their industry in a way other sectors don’t face, which is the basis of the equal protection claim.
“What they’re saying is in essence that these actions the municipality is taking are arbitrary and capricious, which is one of the sort of catch-all standards,” Thomas Allen, a partner at K&L Gates, told me. “They say the laws lack a rational basis. And then they make equal protection claims, saying data centers are being singled out because of political concerns as opposed to actual things relevant to the legislature’s directive. They’re not basing their decisions on the underlying merits of the project but reacting to political pressure.”
“It’s a reliance question and it’s about the treatment of their projects,” added Laura Morton, an attorney with Ashurst Perkins Coie. “It’s always been important to talk about and engage with communities where your infrastructure is planned. Here, I think this is the developers going in, maybe having conversations, and then suddenly they’re getting a reversal after already receiving these approvals and making investments based off of what the conversations and rules were.”
The likelihood of these constitutional challenges reaching higher courts anytime soon is quite low. It’ll be a long time before we see one of these cases reach a verdict, let alone some kind of appeals process come to fruition. Nevertheless, the new legal ambiguity around these local restrictions is an important new facet of the data center wars, including for developers.
“Companies want to act within the law to get [things] done, so whatever tactics they can do to help get the project over the line that are legal and ethical, they may try those,” Allen told me. “And if that includes the pressure of a lawsuit, that’s a judgment they’ll have to make.”
And more on this week’s conflicts around project development.
1. Montgomery County, Pennsylvania – We reached a new normal in the data center backlash, and it all seems to have started in King of Prussia.
2. Columbia County, Wisconsin – The gubernatorial race in this state is transforming local fights over wind projects into must-watch popcorn fodder for anyone obsessed with the state of the energy transition, or national politics for that matter.
3. Shelby County, Alabama – One quick update on the intervention of John Rich, the country star turned Trump’s “special envoy for American landowners,” in an Alabama Power transmission project: it’s getting a lot more elected officials involved.
4. New Jersey – We try to conclude every Hotspots on a positive note. So this week’s silver lining comes to you from the Garden State, where state regulators have approved more than a dozen agrivoltaics projects.
A conversation with Ella Nilsen — formerly of CNN, now with Echo Communications — about where we stand in the fight over the energy transition.
This week’s conversation is with Ella Nilsen, who recently left CNN as a climate reporter and is now a new vice president at energy and cleantech PR firm Echo Communications. Having worked on Capitol Hill alongside Nilsen, I knew her to be an exceptional reporter who asked hard questions of those in power on all sides. So when I found out she was taking her journalism hat off and putting the comms cap on, I wanted to do something you rarely get to do with one of your reporting peers: ask for her own opinion about where we stand in the fight over the energy transition.
Our chat was lightly edited for clarity.
What’s it like going from CNN and climate journalism to advising on communications in the energy sector, especially when it comes to clean tech in this fraught moment?
So before I covered climate and clean energy, I was a political reporter who covered campaign cycles and Capitol Hill for a while, and I was always interested in the nexus of politics and politics. I tried to make as much of my coverage about that. Politics is policy, and the other way around.
Being on the other side of it is, well, I know from my experience as a reporter what interests them. I’m trying to figure out ways to make sure when I’m bugging you all that the pitch lands, because hopefully it’ll be something people are interested in. Things are changing so fast. It’s a really fascinating time to be a reporter and be in the clean energy comms space.
Okay, but now that you’re in clean energy comms, how do you handicap the fight over developing these technologies? Who is winning, who is losing, and why?
I think it’s tough to call exact winners and losers right now because over the last few months, there have been so many new and interesting developments.
Look at the Invest in Tomorrow Coalition, which has been getting involved in Republican primaries for Freedom Caucus members. There’s been this perception for a long time that the clean energy industry didn’t fare well in the One Big Beautiful Bill Act fight. They had important wins while losing pretty key stuff. But there’s been this interesting reckoning within the industry, and even this last summer, where people are moving the ball forward in interesting ways. They’re trying to get involved in political fights with direct results.
What messages do these primaries send? On the one hand I can see there being political consequences but also, now, more solar energy money going into Republican politics has the anti-renewable folks saying they need to go harder at them. I’m curious how you see the energy fight landscape changing in light of these election results.
I think it shows the industry has some fight in it. What the Coalition would probably say is, they want to be lethal and this is political warfare. They’re trying to be taken seriously.
There is sort of this two-pronged strategy happening right now. Obviously Invest in Tomorrow has gotten a lot of press attention for their track record. There’s also within the industry an attempt to shape a public narrative around wind, solar, battery storage to combat misinformation, both through conventional media and social media. They’re happening in tandem and it's a reflection of the results.
How is the backlash over data center development affecting the work you’re now doing?
Well, I’m still early, but I think the data center question is a fascinating one. Conversations around policy and where we go from here really seem to me to be happening in the state realm. Not a lot of policy happening at the federal level. There’s New York State’s data center pause, which is leading to lawmakers trying to get more leverage.
It’s in the backdrop, where projects are being announced with massive power plants to supply new data center demand, and at the same time there’s a conversation around virtual power plants, DERs. Another phrase emerging for it is “community power.”
It’s starting to be a fascinating conversation around community benefits. There are tax benefits when a data center comes to town but when it comes to energy use, what can communities actually leverage out of this? I know former Energy Secretary Jennifer Granholm has been arguing for strong community benefit agreements, getting big tech companies to pay for solar and EVs and then using all of that to create a virtual power plant. Getting that to be flexible for data centers. That’s only one part of the pie but it’s fascinating to have this conversation about what forms of energy we need for all this demand happening.
What do you foresee about the impact of the backlash, given that land use, visuals, air, and water – its all being swept up in the same conversation?
I don’t have a crystal ball and have the same questions.
It’s all happening so quickly and it’s all playing out in so many different states. There are really important questions here and there are people smarter than I am on this, talking about how we meet this demand in the short term and long term or whether this is an opportunity for getting clean energy onto the grid. But it’s a delicate dance.
