The whales will be fine.

Donald Trump loves eagles and whales and therefore he wants to protect them — from clean energy development.
Trump may, however, be relieved to hear that many of his concerns about wind and solar energy are unfounded. Here’s what he gets right and wrong.
Pointing out the window to the Atlantic Ocean at one point, one attendee said, the former president claimed that offshore wind turbines break down when they are exposed to saltwater … [April 17, 2024]
Fact check: Let’s just get this out of the way: offshore wind turbines are designed to withstand saltwater exposure. People have been building things in saltwater for a long, long time. From the oldest known ships constructed 6,000 years ago out of papyrus reeds to Norway’s Troll A platform — a reinforced concrete offshore natural gas platform and the tallest structure ever moved by humankind — we’ve learned a few things about resisting salt corrosion.
This scene occurred during a fundraising dinner with oil and gas executives at Trump’s Mar-a-Lago resort reported on by The Washington Post, which also pointed out this obvious fact. That said, to the former president’s credit, “the ocean is indeed a difficult environment” for construction and engineering, Eric Hines, a civil and environmental engineering professor and the director of the offshore wind energy graduate program at Tufts University, told me. But the lifespan of offshore structures can range from a few years to more than a century.
According to Hines, most offshore wind farms today are built to have “approximately 25-year service lives,” but the design is always evolving. His department, for example, is working on developing advanced underwater foundations that are built to last more than a century and double as artificial reefs.
“I like the concept of solar, but it’s not powerful like what we need to fire up our factories.” [Dec. 16, 2023]
Fact check: “That question is actually a little bit tricky,” Baker, the assistant professor of engineering at the University of Colorado, told me, when I asked him whether solar alone could power a factory — but it’s also not really what we should be asking. “One thing I’ve noticed people do a lot is they’ll just compare efficiency of power generation,” Baker explained. But “it’s not just about the efficiency — it’s about other things, too, like solar’s ability to be distributed. You can’t put a nuclear fission power plant in your house — you know, not yet — but you can put solar panels, so that’s a huge benefit. It offers some resiliency that other sources just can’t offer.”
It’s true that solar power is less efficient than other sources of energy, including wind, and that it requires a lot of surface area, which could be an undue burden for a manufacturer. But at the same time, “I don’t know if anybody is proposing to power an entire factory based off of solar,” Baker said.“Their windmills are causing whales to die in numbers never seen before. Nobody does anything about that. They’re washing up on shore. I saw it this weekend: Three of them came up! You wouldn’t see it once a year; now they’re coming up on a weekly basis. The windmills are driving them crazy. They’re driving the whales, I think, a little batty.” [Sept. 25, 2023]
Fact check: If you ever want to feel ridiculous, try asking a scientist at the National Oceanic and Atmospheric Administration if windmills are making whales “a little batty.”
NOAA actively studies how “sound, vessel, and other human activities” impact marine life, Lauren Gaches, the director of NOAA Fisheries Public Affairs, told me over email. “At this point, there is no scientific evidence that noise resulting from offshore wind site characterization surveys could potentially cause mortality of whales,” she said.
An ongoing “unusual mortality event” for humpback whales has resulted in 200 whale deaths between 2016 and June 2023 along the Atlantic coast from Maine to Florida — that much is true. But “there are no known links between recent large whale mortalities and ongoing offshore wind surveys,” Gaches told me. NOAA’s fact page on whales and offshore wind explains that of “roughly 90 whales examined, about 40% had evidence of human interaction, either ship strike or entanglement.”
There has been some chatter about underwater surveying work disrupting whales, which may be true in the case of oil and gas surveys, which use seismic air guns to penetrate deep into the ocean floor. The surveying equipment used for offshore wind is, by contrast, used in 15-second bursts and limited to a specific area, “so the likelihood of an animal encountering and coming right into that sound beam is quite low,” Erica Staaterman, the deputy director for the Bureau of Ocean Energy Management’s Center for Marine Acoustics, said on a NOAA-hosted call with the press early last year.
As Ben Laws, the deputy chief of NOAA’s Permits and Conservation Division in the Office of Protected Resources, said on the same call, “There is no information that would support any suggestion that any of the equipment that’s being used in support of wind development for these site characterization surveys could directly lead to the death of a whale.”
“If you go out hunting and you happen to shoot a bald eagle, they put you in jail, like, for five years, right? They kill thousands of them with these windmills; nothing happens.” [Jan. 28, 2023]
“If you want to see a bird cemetery, go under a windmill sometime. You’ll see birds like you never saw. If you love birds, you’ll start to weep.” [Dec. 16, 2023]
Fact check: Trump has had a vendetta against wind turbines since long before he ever ran for president. “Wind farms are killing many thousands of birds,” reads one illustrative tweet from 2012. “They make hunters look like nice people!”
Lewis Grove is the director of wind and energy policy at the American Bird Conservancy, and he told me that while it’s “not necessarily as simple as Mr. Trump painted it out to be, wind turbines absolutely kill birds.”
But the context here is extremely important. Jason Ryan, a spokesperson for the American Clean Power Association, a leading renewable energy trade group, pointed me to research from the U.S. Fish & Wildlife Service that shows wind farms “represent just 0.03% of all human-related bird deaths in the U.S.” Grove likewise told me that, for the most part, bird deaths due to wind turbines do “not have population-level impacts.”
There are exceptions, such as an infamous wind farm in California’s Altamont Pass built in 1981 that “just happened to be in a place that was really heavily used by golden eagles,” Grove told me. Because golden eagle populations were already very low, having 100 or so killed a year by turbines was “unsustainable.” Even in a case like this, though, it behooves one to look at the whole picture: “They found it was a few individual turbines that were causing the damage,” Grove said. These days, around 60 golden eagles a year are killed in Alameda County, the Alameda Post reports, and the operating company must pay steep penalties for eagle deaths.
What’s more, “climate change is one of the greatest threats birds face, with two-thirds of North American species at risk of extinction due to our warming planet,” Jon Belak, senior manager of science and data analysis at The National Audubon Society, told me in a statement. “We need to build more wind and solar facilities to help slow the rise in global temperatures and protect birds and their habitats from a changing climate.”
Wind farms may not have population-level impacts on birds, but fracking does — “the onset of shale oil and gas production reduces subsequent bird population counts by 15%,” even after accounting for factors like weather and other land-use changes, according to one just-published, peer-reviewed study.
“Remember the windmills? ‘Darling, darling, I want to watch the president, I love him so much. I want to watch him on television tonight.’ ‘I’m sorry, but the wind isn’t blowing, you’ll have to wait ‘til another time.’ Windmills.” [March 26, 2022]
Fact check: “I mean, it’s possible with any mix of generation that if supply and demand aren’t equal, your TV will go out. That’s just physics,” Kyri Baker, an assistant professor of engineering at the University of Colorado, told me when I asked her if Trump’s scenario had any merit. In other words, a power outage could happen whether your electricity is coming from coal or natural gas or anything else. The difference, she said, is that “wind is by nature variable, intermittent. But it’s also not reliant on fuel like natural gas or coal plants or even nuclear plants are.”
What happens on days when there is no wind? “Grids are extremely regulated,” Baker explained to me. “There’s so many layers of redundancy that aim specifically to not have [an outage] happen.” A grid is made up of diverse electricity sources (for my visual learners, Canary imagines what a net-zero grid could look like here), as well as measures like offline backup generators, which can kick in if need be, so service isn’t disrupted.
Battery storage is another huge part of this equation. While they’re still fairly cutting-edge as climate technology goes, high-capacity batteries that can manage grid-scale energy needs are getting better and more plentiful.
“Stop with all of the windmills all over the place that are ruining the atmosphere.” [Jan. 20, 2022]
Fact check: Wind turbines do not damage the literal atmosphere.
But maybe Trump meant atmosphere as in “sense of place”? Most Americans don’t seem to think windmills are “ruining” anything. In a recent Heatmap poll, nearly eight in 10 Americans said they want the government to make it easier to build new wind farms. The Washington Post similarly found last year that about 70% of Americans said they wouldn’t mind living near a wind farm.
As my colleague Robinson Meyer has written, “American laws today give even a small, well-resourced minority plenty of tools to block a project” like a wind farm, and “what’s more, once that small group starts campaigning against a project, the public’s broad but shallow support for, say, a general technology can crater. That’s what happened recently in New Jersey, where a once broadly pro-wind public has turned against four proposed offshore wind farms.”
“It’s a very expensive form — probably the most expensive form of energy.” [Jan. 20, 2022]
Fact check: Wind in general is not the most expensive form of energy, but offshore wind is very expensive — for now.
Of the energy sources we’re currently used to, nuclear is usually cited as having the highest levelized cost of electricity — that is, it has the highest average cost per unit of electricity generated after construction, maintenance, and operation have been taken into account. Peaker plants — gas-powered plants that run just during times of peak demand — usually come in second.
Offshore wind is costly, with the levelized cost of electricity from a subsidized U.S. offshore wind project increasing “to $114.20 per megawatt-hour in 2023, up almost 50% from 2021 levels in nominal terms,” BloombergNEF reports. Many of the factors making offshore wind so expensive — including permitting delays, high interest rates, and supply chain issues — will abate with time. Meanwhile, onshore wind is one of the cheapest forms of electricity available and has boasted a “lower LCOE than gas plants since 2015,” Sustainable Energy in America reports.

Seattle practiced responding to a heat dome during the international soccer tournament. It didn’t go well.
Welcome to Seattle! If you’re one of the 750,000 visitors in town to watch the 2026 North American FIFA World Cup, you’re going to love it here. For one thing, you’ve arrived just in time for the city to suspend its interminable construction for the games. That’s a plus! Be sure to check out our newly pedestrianized Pike Place Market and stroll along the waterfront to “Seattle Stadium” (or sound like a local and call it “Qwest”). You might even get a little chilly from the wind off the bay — you can thank our “temperate, oceanic climate” for that. It’s what makes Seattle the safest place in the United States to attend (or play in) a World Cup game, per researchers at Queen’s University Belfast — at least, from the perspective of extreme heat.
That’s worth bragging about. Extreme heat has been a concern at almost every subsequent World Cup going back to the 2014 World Cup in Brazil, including the 2022 tournament in Qatar, which FIFA had to reschedule to the winter. The 2026 World Cup could get dicey, too. Of the 104 scheduled matches in 16 host cities in the U.S., Canada, and Mexico over the next month, at least half have a 50% chance or greater of being played in temperatures of 82 degrees Fahrenheit or higher, according to research by Climate Central — that being the threshold at which player performance begins to suffer, with athletes slowing down, getting sick, and making poorer decisions because of the heat. The odds of there being impairing heat during the World Cup final in New York on July 19 are basically a coin flip, and 17% higher than they otherwise would have been due to climate change-induced warming.
All of that is just part of what makes Seattle’s host city status so appealing. There is only about a 3% chance of performance-impairing heat during its two mid-June fixtures, rising to 6% later in the month and into July.
Unless, of course, there’s another heat dome.
In 2021, temperatures in Seattle peaked at 108 degrees on June 28, which this year will fall between when the city hosts Egypt vs. Iran and a Round of 32 match. Needless to say, 108 degrees is not just perspiration-inducing; it is well beyond the 89.6-degree wet-bulb globe temperature threshold at which FIFA considers postponing matches. While the possibility of another heat dome in the next few weeks is admittedly an edge case — before 2021, Seattle had only touched 100 degrees three times in 126 years of recorded-keeping— it’s still a realistic enough possibility that last spring, the National Weather Service’s Seattle office ran a tabletop exercise with its local partners to game out just that.
“Before 2021, heat [in Seattle] was just another hazard alongside fire and smoke and those sorts of things,” Reid Wolcott, the warning coordination meteorologist with the NWS Seattle, who helped lead the two-day-long run-through, told me. The heat dome “really highlighted that heat is a powerful hazard that can cause significant loss of life.”
After more than 400 people died in Washington alone, the NWS dedicated considerable time and resources to its heat preparedness and messaging in the Pacific Northwest. Beginning in 2022, the National Integrated Heat Health Information System began offering technical support for heat tabletop exercises in communities around the country. Seattle was supposed to participate in 2024 but “due to some logistical reasons, we ended up delaying it until 2025,” Wolcott said. “And because of that, we were like, We’re well on our way into World Cup planning, here.”
The idea of the “Heat Dome Cup” exercise was to kill two birds with one stone — to test the Seattle area’s response four years after the heat dome, as well as its ability to respond to a weather crisis when thousands of visitors are in the city for the World Cup. Participants included representatives from surrounding cities such as Bellevue, Everett, and Portland, Oregon; county-level offices including from climate, emergency management, and public health; the University of Washington; and the Port Gamble S’Klallam Tribe.
The results of the exercise were both encouraging and not: For every core capability tested, from “threat/hazard identification” to “communication” and “community resilience,” the after-action report found that Seattle “performed with some challenges.” There was “limited local data” on the compounding hazards of heat, cooling center efficiency, and — particularly alarming — the local healthcare system’s ability to respond during such an event. “Prehospital triage, surge planning, and better integration with public health systems are urgently needed,” the report found. Because paramedics attempt to bring down a heat stroke patients’ temperature before transporting them to a hospital — a laborious process often involving filling a home bathtub with ice, setting the patient in it, and waiting — the emergency response during heat events is slow, and can quickly back up and overwhelm the system.
Heat Dome Cup partners directed my questions about King County’s readiness to handle extreme heat during the World Cup to the public health office, which told me no one was available for an interview.
Carlos Martinez, a senior climate scientist with the climate and energy program at the Union of Concerned Scientists who did not participate in the exercise, told me that after reading the report, he hopes that “there’s a recognition and awareness of the fact that there’s a lot of work that needs to be done.” He also flagged an observation from the exercise regarding the development of stronger workplace protections during the World Cup.
“That sometimes can be neglected,” he went on. “You have folks in construction, food service, retail, landscaping, and sanitation who work a full day outside during these events. What are the protocols that are out there to ensure that they are protected from heat-related illnesses?”
I put the question to Hollie Stark, the communications coordinator for the Office of Emergency Management in Seattle. (While Stark’s office participated in the exercise, Stark did not.) She told me that Washington’s Department of Labor & Industries offers recommendations for how employers can protect their workers from heat and smoke, including running trainings and publishing posters and pocket cards in multiple languages that promote offering adequate water, shade, and breaks. “We’re thinking about maybe bars and places that might be hosting [FIFA viewing parties] that don’t have access to AC but might have an influx of people,” she said as a hypothetical, “and we’re encouraging them to listen to those recommendations.”
In general, the people I spoke with in Seattle who were involved in the exercise acknowledged that messaging and communication were the areas the city struggled with the most. “That has definitely been the single biggest thing — trying to make sure that we’re all singing from the same sheet of music,” Wolcott told me. “Because we weren’t prior to 2021.”
One of the biggest hurdles has been figuring out exactly how to communicate potential extreme heat warnings to the thousands of visitors traveling to Seattle. During my conversations with officials involved in the Heat Dome Cup, officials pointed me to myriad preparedness websites, real-time risk tools, opt-in alert systems, and health and safety resources for out-of-town visitors, which left me — a local fluent in English — feeling even more confused.
Language itself is one thing — on that front, Stark told me her office has already pre-scripted messaging for extreme heat translated into Spanish and the eight threshold languages of King County — Vietnamese, Somali, Russian, Chinese, Korean, Amharic, Arabic, and Ukrainian — as well as seven additional World Cup spectator-specific languages — Arabic, Farsi, Dutch, French, Bosnian, Serbian, and Croatian. But one of the threats of having a heat dome during a major sporting event is that “you have a lot of visitors coming from all different parts of the world,” Wolcott said. “Some come from locations where they are probably more acclimated to heat than we are, but some may be coming from areas that are cooler climates than ours.” Proper acclimation can take weeks, if not an entire season — far longer than most spectators will be in town.
But perhaps the biggest takeaway is that a heat dome isn’t required for people to be under heat stress, even in a place as temperate as Seattle. Wolcott told me the NWS’s seasonal outlook for the summer in the region indicates above-average temperatures, and while that “does increase the risk of a heat event occurring, it has nothing to do with the actual magnitude of it. You could have a 2021-level event, or you could have 30 smaller events, and there is no way to tell exactly what’s going to happen.”
Indeed, even fairly moderate temperatures can sneak up on spectators. While FIFA is in charge of making decisions that impact their athletes’ health, Shel Winkley, the senior engagement specialist and meteorologist at Climate Central, pointed out that “fans are still sitting in the sun in the heat, and if they’re fans like me, they’re not drinking water during [the FIFA-mandated in-game] cooling breaks.” Spectators get to the stadium early, stand in long lines in the sun, sit in crowded stadiums with potentially no shade — and essentially endure an entire day of heat, even if the temperatures seemed manageable when they walked out their hotel door.
At this point, there is nothing to indicate Seattle’s worst-case scenario will come true. (Stark also mentioned that a true worst-case scenario more likely involves the Big One than extreme heat, but we won’t go there.) But “just because historically the odds are low” for a heat dome in the Seattle area “doesn’t mean that they’re zero,” Winkley said.
Martinez, the climate scientist with UCS, stressed to me that while the Heat Dome Cup was an engaging thought experiment, bringing together 30 distinct partners for two whole days, he fears that a gutted NWS and Federal Emergency Management Agency might lack the funding or personnel to act on the weaknesses the exercise exposed. “If you have this one exercise but no follow-through, that can risk eroding trust by those populations who gave time out of their day to come and speak to the federal government about the importance of this issue,” he told me. “We shouldn’t just do this for well-renowned events. This should be an evergreen thing.”
But Wolcott, the lead on the Heat Dome Cup, sounded to me like he was at the end of a long marathon when I spoke to him. “I’ve been planning for [the World Cup] for three years now. I’m ready for it to be over,” he told me, laughing.
“We are always doing this; it was just one exercise that we did last May,” he added. “I’m just looking forward to late July at this point.”
Current conditions: Tropical Storm Cristina is inching north toward landfall in Central America, threatening floods, landslides, and winds of up to 73 miles per hour • Washington, D.C., is poised for rain for the rest of the week as temperatures rise to nearly 100 degrees Fahrenheit by Friday • By contrast, Cartersville, Georgia, where the solar manufacturer Qcells just started up its factory, is looking at a two-day break of sunshine from an otherwise gray and wet forecast.
At the start of 2023, South Korea’s biggest solar manufacturer, Qcells, began construction on a sweeping new factory northwest of Atlanta in Cartersville, Georgia. Betting that U.S. tariffs on Chinese solar panels were here to stay, the company gambled on bringing most of the supply chain under one roof. On Tuesday, Qcells started producing solar cells at the plant, marking what it called “a major milestone toward completing the country’s only vertically integrated solar manufacturing plant.” The firm expects to reach full production by the third quarter of this year. The factory’s module assembly line, meanwhile, is now at full capacity, building 16,700 panels per day. “Producing the first solar cells at Cartersville is a milestone for Qcells and for American manufacturing,” Andy Park, the global chief executive of Qcells, said in a statement. “As our ingot, wafer, and cell lines reach full capacity, we’ll be making the major components of a solar panel right here in Georgia.”
The U.S. could be seeing the start of a small solar boom. Last year alone, at least 30 new utility-scale solar factories came online, as Heatmap’s Emily Pontecorvo reported last month.
Over the weekend, as I told you on Monday, a federal court blocked the Trump administration’s rules for using the soon-to-expire tax writeoffs for investing in or producing electricity from solar panels and wind turbines. But with just 24 days to go until the tax credits officially end, few developers are likely to move quickly enough to benefit from the ruling. “Practically speaking, I don’t think this is likely to have much impact on the market or behavior in the coming weeks,” Heather Cooper, a tax lawyer at McDermott Will & Schulte, told E&E News. “The deadline is less than four weeks away.”
Investments into electrical grids are on track to surpass $650 billion globally this year, according to new data from the consultancy Rystad Energy. That’s up 5% from last year and more than double the investments recorded in 2020, PV Magazine reported. The high cost comes as long lead times and pricy components for transformers, high-voltage circuit breakers, and switchgears strain and stall upgrades and expansions to power systems all over the world. The soaring growth of wind and solar is propelling grid investments, which are needed to patch more intermittent and often far-flung renewables onto the system. In 2010, wind and solar made up just 2% of global generation. By 2040, Rystad expects them to make up nearly half the mix.

Everyone recognizes Canada as a major oil producer, metal miner, and hydroelectricity generator. But did you know the Canucks are not just a serious player in nuclear power, but actually have their own domestically-designed reactor that can run on raw uranium? Get this, it even has a catchy name: the CANDU. Pronounced CAN-do and short for Canada Deuterium Uranium, the pressurized heavy water reactors are among the only commercial designs in the world that can run on unenriched, natural uranium. The advantage, especially for a country like Canada with vast uranium deposits, is that they’re faster to build, cheaper to fuel, and free of the international scrutiny that comes with enriching uranium. The downside is that they break down faster than the light water reactors that make up the entirety of the U.S. fleet. But Canada is demonstrating that isn’t a big problem. On Monday, the Bruce nuclear power station brought its Unit 3 reactor back online, completing refurbishments seven months early and $107 million under budget, NucNet reported. You don’t need to know a lot about the American or European nuclear industries to know “early and under budget” aren’t words typically associated with any recent or ongoing projects.
The best-proven way to make truly green steel involves turning iron ore into direct reduced iron through a process that, when powered by green hydrogen instead of natural gas, significantly slashes any carbon emissions associated with its production. Assuming it’s finished off in an electric arc furnace, it’s green steel — and even greener if that final process was powered by renewables or nuclear. Yet despite some high-profile projects, green hydrogen has remained too expensive in the West, even as China’s industry starts to boom. That could be changing. On Tuesday, the German steelmaker Salzgitter inked its first major offtake agreement for green hydrogen from the supplier EWE, Hydrogen Insight reported. One of Germany’s largest steel producers, Salzgitter will buy roughly 10,000 metric tons of hydrogen per year from the electrolyzer plant EWE is building in Emden, near the Dutch border.
Meanwhile in America, U.S. Steel unveiled plans to invest up to $2.5 billion into upgrading the Mon Valley Works, southeast of Pittsburgh. The renovations come after Japanese steel giant Nippon’s takeover of the iconic American firm last year. To win President Donald Trump’s blessing, Nippon gave the federal government a “golden share” in the company. As Heatmap’s Matthew Zeitlin wrote last year, that could ultimately give a future administration leverage to press U.S. Steel to green its operations.

If you’re booking a flight right now, you might not yet be feeling the difference. But U.S. production of jet fuel has reached record highs as refiners scramble to respond to soaring prices following the closure of the Strait of Hormuz. By the start of May, the four-week average estimate of fuel production surpassed 2 million barrels per day for the first time on record, according to new analysis by the Energy Information Administration. But with domestic inventories still relatively high, much of that increased production is being exported.
Entech’s S2 platform debuted last year to help make century-old boilers more efficient.
Emissions from existing buildings are responsible for about 70% of New York City’s climate emissions, with space heating as the dominant source. Yet most of the city’s multifamily buildings still rely on central steam boilers that cycle on and off when the outdoor temperature drops below a certain threshold, regardless of indoor conditions. The result is a system that leaves many residents sweltering in the dead of winter, wasting fuel and money while releasing unnecessary greenhouse gases.
Completely overhauling and modernizing a central boiler system — many of which date to the early 1900s — and installing a building-scale heat pump could address many of these issues. But that’s an expensive, complex, and disruptive endeavor that many building owners either can’t afford or simply don’t want to undertake. And while heat pump startups such as Quilt and Gradient are making inroads in single-family homes and individual apartment units respectively, neither is working to optimize the operations of existing steam boilers, which remain the dominant heating source for New York’s apartment stock.
That’s where Entech, a 30-year-old building energy management company, comes in. The company’s platform has long used indoor sensors to monitor the performance of central boilers and help them run more efficiently. Last year, however, the company revamped its software to incorporate artificial intelligence. The new system, called S2, autonomously monitors 20-plus sensors installed throughout the buildings where it operates, adjusting heating cycles with greater precision while continuously tracking the overall health and performance of boiler room operations.
On Wednesday, the company announced the results from the S2’s first year of operations: Across 401 New York City apartment buildings, the platform slashed emissions by nearly 25%, avoiding more than 16,000 metric tons of carbon pollution and generating over $5 million in savings for property owners.
Previous iterations of the company’s tech relied on preset rules such as, “When it’s 55 degrees [Fahrenheit], you need a shorter cycle, and when it’s 20 degrees, you need a longer cycle,” Heather Zoberman, Entech’s director of product development, explained to me. Those settings dictated how long a boiler turned on and how long it stayed off. With AI, however, the company can measure how quickly individual units are actually heating up and adjust performance in real-time.
For a company that spent decades focused on incremental improvements to boiler operations, it’s a meaningful shift. “Now we have the ability to do flame modulation — so a higher flame, a lower flame— based on the load, based on the building temperatures,” Zoberman told me. The same level of granular control applies to the fans and pumps that move heat through the building, too. “A little bit slower fan, a little bit lower flame is really where you get those savings that add up,” she said. According to Entech, those savings are typically passed onto the residents, with the average tenant saving roughly $200 on heating costs last year.
While building owners are happy to see these savings too, many are turning to Entech primarily to comply with the New York City Council’s Local Law 97, which requires buildings larger than 25,000 square feet to cut emissions 40% by 2030 compared to 2005 levels, and reach net zero emissions by 2050.
The nonprofit housing developer and operator Breaking Ground, for example, builds supportive housing for low-income and formerly homeless New Yorkers, and has been doing so for decades. It adopted Entech’s new boiler control system just six months ago to comply with the emissions law. While Breaking Ground’s deputy VP of facility operations, Lorenzo Torres, didn’t have exact savings figures on hand, he said the system has saved the organization “a lot of money,” largely by enabling staff to remotely identify equipment issues such as leaks and temperature fluctuations without having to send anyone to the building and before they develop into expensive headaches.
“We do have a work order system, but data is only as true as the person that’s entering the data,” Torres explained. Thus if a tenant misidentifies an issue or fails to file a work order in the first place, Breaking Ground might assume everything is running efficiently. By contrast, “the S2 controller actually is able to, with conviction, let us know that there is an issue with the boiler,” he said.
What Entech’s system still can’t do is solve the problem of unit-level temperature variation. Factors such as floor level, window exposure, and radiator placement mean some apartments will naturally run hotter or colder than others. But because Entech primarily operates in apartment complexes with central boilers, it can still only make adjustments at the building level Because of this, its system could be a complement to something like a smart radiator, which can control how much heat each apartment receives.
Now, Entech is looking to expand beyond New York. Boston is a natural next market, Zoberman told me, given its stringent building emissions requirements. Chicago is also on the company’s radar, thanks in part to incentives from the natural gas utility People’s Gas, which can help offset the cost of energy efficiency upgrades. The company’s ambitions extend beyond just geographic expansion, however — it’s also broadening its platform to monitor and optimize central cooling systems and other electrified technologies such as heat pumps and mini splits.
It looks like it should have plenty of room to run. Additional jurisdictions from Washington D.C. to St. Louis are increasingly adopting hard caps on building emissions, while dozens more now require annual energy-use reporting — often a first step towards more stringent regulation.
