This week's hottest real estate listings were all about over-the-top sports fandom and over-the-top climate risks.

Glued to real estate posts on The New York Times, The Wall Street Journal, Dwell, Spaces, The Modern House, or Architectural Digest and wondering how those gorgeous homes will hold up in the next decades? I have you covered.
Heatmap has partnered with my new climate risk platform, Habitable. Every Friday, we add a climate risk score to the real estate listings featured in the news this week and ask: Could you live here as the climate changes?
Using a model developed by a team of Berkeley data scientists at Climate Check, Habitable scores each property for heat, flood, drought, and fire risk on a scale of 1-10. One represents the lowest risk and 10 is the highest. Our rating for each hazard is based on climate change projections through 2050. (You can check your own home’s climate risk here.)
For today’s edition, I apply the Habitable Index to houses in the news this week that are notable for over the top sports amenities. The properties feature soccer fields, golf courses, pickleball courts, and so many basketball courts.
Read on to see if the properties of this competitive set are habitable.

The 7-acre Spring Ivy Estate in Old Westbury, New York, is on the market for $50 million. It’s not a house, it’s a resort. Amenity rich, the house is 25,000 square feet with grand luxurious rooms. There are soaring ceilings, a formal dining room, seven bedrooms, 13 bathrooms and an indoor-outdoor kitchen. It may not seem worth the price tag until you reach the lower level entertainment ‘complex.

There’s a game room, gym, indoor pool, billiards room, a bowling alley, 12-seat movie ‘complex’ with a real sports bar — including three screens over the bar. But what makes it worth the ticket price is the professional NBA-grade basketball court and an indoor golf simulator. The property scores well for climate risk, so let the games begin.
Featured in Mansion Global and listed for $50 million.

The co-owner of the Boston Celtics listed his suburban estate in Weston, Massachusetts, for sale as he downsizes. On 4 acres, it’s 15,000 square feet with seven beds, seven bathes, not one, but 2 basketball courts (one indoor, one outdoor), along with a spa, gym, courts, and a pool. For ultra wealthy, climate-concerned, basketball-crazed buyers, it’s a slam dunk: The house has no risk for flood, barely a risk for drought or fire, and moderate heat risk. There will be years to practice foul shots all day long, year round, in any weather.
Featured in WSJ for just under $9 million.

Super Bowl-winning quarterback Patrick Mahomes has put his Kansas City, Missouri, home on the market for $2,900,000. It’s a small house in a chic neighborhood (near the country club!), but it doesn’t lack amenities. The house has a closet that fits Mahomes’ entire collection of 180 pairs of Adidas sneakers, plus a putting green in the backyard. Habitable checked: The climate forecast, while HOT, is also a winner.
Featured in The Kansas City Star and listed for $2.9 million.

This seven-bedroom, eight-bath stone house in Nashville, Tennessee, has all the amenities of a luxury hotel: two pools, a spa, and a full gym that you won’t have to share with other guests. Perfect for a multi-sport family, there’s lots to do here — gardening, cooking at the indoor-outdoor kitchen, swimming laps, and working out at the gym along with playing tennis, pickleball, volleyball, or basketball on the multi-sport court. The only drawback is the boiling heat — hopefully any exercise-loving buyer likes to sweat.
Featured in Mansion Global and listed for just under $10 million.

He’s not Liberace, but Rod Stewart's house decor will make you wonder. For $70 million, his just-listed, 28,000-square-feet Beverly Hills mansion offers a professional soccer field with two full-size gyms and the most luxurious workout yet.

But hydration will be a problem with extreme flood and fire risk forecasted for the property. Run. Run. Run. Fast.
Featured in The Real Deal and listed for $70 million.

This sprawling house in Rancho Mirage in the desert of Coachella Valley looks lush as you drive up the long, gated drive lined with old-growth carob trees. Amenities and activities abound here. Where to start the workout? Try the gym housed in a former stable, then jump in the 80-foot pool before sweaty games on the tennis court, basketball court, putting green, and bocce ball and competitive horseshoe court. Only then are you allowed to check out the hammock. The punishing schedule is no more punishing than the climate here. A full menu of possibilities await but habitability is not one of them. There’s extreme risk of drought, and medium risk for heat, floods, and fires. Yikes.
Featured in Dwell and listed for $4 million.

Outside of Salt Lake City Utah, this 50,738-square-foot home is one of the largest homes in the United States (it’s apparently as big as the White House). The theater here has 27 seats! There are 20-foot ceilings and two staircases out front. There are hundreds if not thousands of chandeliers. Sculptures, ornamental window hangings, bathtubs for two! It’s all here for you.
And then some. The pool is not just a pool! It’s a water slide, with a lazy river and rope swings. There is a basketball court, a two-lane bowling alley, a 27-seat theater room, an exercise room, a game room. There is a pirate ship and slide in the children’s play room. And that is just inside.

Outside are trails for hiking, biking, camping, hunting, horseback riding, ATV riding, snowmobiling, and cross-country skiing.
Jam packed, but habitable? Sadly, no, because this $17 million house, the pool, the chandeliers, all of it are at extremely high risk of being eventually lost to floods, fire, heat, and drought. Enjoy it while you can.

With more electric heating in the Northeast comes greater strains on the grid.
The electric grid is built for heat. The days when the system is under the most stress are typically humid summer evenings, when air conditioning is still going full blast, appliances are being turned on as commuters return home, and solar generation is fading, stretching the generation and distribution grid to its limits.
But as home heating and transportation goes increasingly electric, more of the country — even some of the chilliest areas — may start to struggle with demand that peaks in the winter.
While summer demand peaks are challenging, there’s at least a vision for how to deal with them without generating excessive greenhouse gas emissions — namely battery storage, which essentially holds excess solar power generated in the afternoon in reserve for the evening. In states with lots of renewables on the grid already, like California and Texas, storage has been helping smooth out and avoid reliability issues on peak demand days.
The winter challenge is that you can have long periods of cold weather and little sun, stressing every part of the grid. The natural gas production and distribution systems can struggle in the cold with wellheads freezing up and mechanical failure at processing facilities, just as demand for home heating soars, whether provided by piped gas or electricity generated from gas-fired power plants.
In its recent annual seasonal reliability assessment, the North American Reliability Corporation, a standard-setting body for grid operators, found that “much of North America is again at an elevated risk of having insufficient energy supplies” should it encounter “extreme operating conditions,” i.e. “any prolonged, wide-area cold snaps.”
NERC cited growing electricity demand and the difficulty operating generators in the winter, especially those relying on natural gas. In 2021, Winter Storm Uri effectively shut down Texas’ grid for several days as generation and distribution of natural gas literally froze up while demand for electric heating soared. Millions of Texans were left exposed to extreme low temperatures, and at least 246 died as a result.
Some parts of the country already experience winter peaks in energy demand, especially places like North Carolina and Oregon, which “have winters that are chilly enough to require some heating, but not so cold that electric heating is rare,” in the words of North Carolina State University professor Jeremiah Johnson. "Not too many Mainers or Michiganders heat their homes with electricity,” he said.
But that might not be true for long.
New England may be cold and dark in the winter, but it’s liberal all year round. That means the region’s constituent states have adopted aggressive climate change and decarbonization goals that will stretch their available renewable resources, especially during the coldest days, weeks, and months.
The region’s existing energy system already struggles with winter. New England’s natural gas system is limited by insufficient pipeline capacity, so during particularly cold days, power plants end up burning oil as natural gas is diverted from generating electricity to heating homes.
New England’s Independent System Operator projects that winter demand will peak at just above 21 gigawatts this year — its all-time winter peak is 22.8 gigawatts, summer is 28.1 — which ISO-NE says the region is well-prepared for, with 31 gigawatts of available capacity. That includes energy from the Vineyard Wind offshore wind project, which is still facing activist opposition, as well as imported hydropower from Quebec.
But going forward, with Massachusetts aiming to reduce emissions 50% by 2030 (though state lawmakers are trying to undo that goal) and reach net-zero emissions by 2050 — and nearly the entire region envisioning at least 80% emissions reductions by 2050 — that winter peak is expected to soar. The non-carbon-emitting energy generation necessary to meet that demand, meanwhile, is still largely unbuilt.
By the mid 2030s, ISO-NE expects its winter peak to surpass its summer peak, with peak demand perhaps reaching as high as 57 gigawatts, more than double the system’s all-time peak load. Those last few gigawatts of this load will be tricky — and expensive — to serve. ISO-NE estimates that each gigawatt from 51 to 57 would cost $1.5 billion for transmission expansion alone.
ISO-NE also found that “the battery fleet may be depleted quickly and then struggle to recharge during the winter months,” which is precisely when “batteries may be needed most to fill supply gaps during periods of high demand due to cold weather, as well as periods of low production from wind and solar resources.” Some 600 megawatts of battery storage capacity has come online in the last decade in ISO-NE, and there are state mandates for at least 7 more gigawatts between 2030 and 2033.
There will also be a “continued need for fuel-secure dispatchable resources” through 2050, ISO-NE has found — that is, something to fill the role that natural gas, oil, and even coal play on the coldest days and longest cold stretches of the year.
This could mean “vast quantities of seasonal storage,” like 100-hour batteries, or alternative fuels like synthetic natural gas (produced with a combination of direct air capture and electrolysis, all powered by carbon-free power), hydrogen, biodiesel, or renewable diesel. And this is all assuming a steady buildout of renewable power — including over a gigawatt per year of offshore wind capacity added through 2050 — that will be difficult if not impossible to accomplish given the current policy and administrative roadblocks.
While planning for the transmission and generation system of 2050 may be slightly fanciful, especially as the climate policy environment — and the literal environment — are changing rapidly, grid operators in cold regions are worried about the far nearer term.
From 2027 to 2032, ISO-NE analyses “indicate an increasing energy shortfall risk profile,” said ISO-NE planning official Stephen George in a 2024 presentation.
“What keeps me up at night is the winter of 2032,” Richard Dewey, chief executive of the neighboring New York Independent System Operator, said at a 2024 conference. “I don’t know what fills that gap in the year 2032.”
The future of the American electric grid is being determined in the docket of the Federal Energy Regulatory Commission.
The Trump administration tasked federal energy regulators last month to come up with new rules that would allow large loads — i.e. data centers — to connect to the grid faster without ballooning electricity bills. The order has set off a flurry of reactions, as the major players in the electricity system — the data center developers, the power producers, the utilities — jockey to ensure that any new rules don’t impinge upon their business models. The initial public comment period closed last week, meaning now FERC will have to go through hundreds of comments from industry, government, and advocacy stakeholders, hoping to help shape the rule before it’s released at the end of April.
They’ll have a lot to sift through. Opinions ranged from skeptical to cautiously supportive to fully supportive, with imperfect alignment among trade groups and individual companies.
The Utilities
When the DOE first asked FERC to get to work on a rule, several experts identified a possible conflict with utilities, namely the idea that data centers “should be responsible for 100% of the network upgrades that they are assigned through the interconnection studies.” Utilities typically like to put new transmission into their rate base, where they can earn a regulated rate of return on their investments that’s recouped from payments from all their customers. And lo, utilities were largely skeptical of the exercise.
The Edison Electric Institute, which represents investor-owned utilities, wrote in its comments to FERC that the new rule should require large load customers to pay for their share of the transmission system costs, i.e. not the full cost of network upgrades.
EEI claimed that these network costs can add up to the “tens to hundreds of millions of dollars” that should be assigned in a way that allows utilities “to earn a return of and on the entirety of the transmission network.”
In short, the utilities are defending something like the traditional model, where utilities connect all customers and spread out the costs of doing so among the entire customer base. That model has come under increasing stress thanks to the flood of data center interconnection requests, however. The high costs in some markets, like PJM, have also led some scholars and elected officials to seriously reconsider the nature of utility regulation. Still, that model has been largely good for the utilities — and they show no sign of wanting to give it up.
The Hyperscalers
The biggest technology companies, like Google, Microsoft, and Meta, and their trade groups want to make sure their ability to connect to the grid will not be impeded by new rules.
Ari Peskoe, an energy law professor at Harvard Law School, told me that existing processes for interconnection are likely working out well for the biggest data center developers and they may not be eager to rock the boat with a federal overhaul. “Presumably utilities are lining up to do deals with them because they have so much money,” Peskoe said.
In its letter to FERC, the DOE suggested that the commission could expedite interconnection of large loads “that agree to be curtailable.” That would entail users of a lot of electricity ramping down use while the grid was under stress, as well as co-locating projects with new sources of energy generation that could serve the grid as a whole. This approach has picked up steam among researchers and some data center developers, although with some cautions and caveats.
The Clean Energy Buyers Association, which represents many large technology companies, wrote in its comment that such flexibility should be “structured to enable innovation and competition through voluntary pathways rather than mandates,” echoing criticism of a proposal by the electricity market PJM Interconnection that could have forced large loads to be eligible for curtailment.
The Data Center Coalition, another big tech trade group representing many key players in the data center industry, emphasized throughout their comment that any reform to interconnection should still allow data centers to simply connect to the grid, without requiring or unduly favoring “hybrid” or co-location approaches.
“Timely, predictable, and nondiscriminatory access to interconnection service for stand-alone load is… critical… to the continued functioning of the market itself,” the Data Center Coalition wrote.
The hyperscalers themselves largely echoed this message, albeit with some differences in emphasis. They did not want any of their existing arrangements — which have allowed breakneck data center development — to be disrupted or to be forced into operating their data centers in any particular fashion.
Microsoft wrote that it was in favor of “voluntarily curtailable loads,” but cautioned that “most data centers today have limited curtailment capability,” and worried about “operational reliability risks.” In short, don’t railroad us into something our data centers aren’t really set up to do.
OpenAI wrote a short comment, likely its first ever appearance in a FERC docket, where it argued for “an optional curtailable-load pathway” that would allow for faster interconnection, echoing comments it had made in a letter to the White House.
Meta, meanwhile, argued against any binding rule at all, saying instead that FERC “should consider adopting guidance, best practices, and, if appropriate, minimum standards for large load interconnection rather than promulgating a binding, detailed rule.” After all, its deploying data centers gigawatts at a time and has been able to reach deals with utilities to secure power.
The Generators
Perhaps the most fulsome support for the broadest version of the DOE’s proposal came from the generators. The Electrical Power Supply Association, an independent power producer trade group, wrote that more standardized, transparent “rules of the road” are needed to allow large loads like data centers “to interconnect to the transmission system efficiently and fairly, and to be able to do so quickly.” It also called on FERC to speed up its reviews of interconnection requests.
Constellation, which operates a 32-gigawatt generation fleet with a large nuclear business, said that it “agrees with the motivations and principles outlined in the [Department of Energy’s proposal] and the need for clear rules to allow the timely interconnection of large loads and their co-location with generators.” It also called for faster implementation of large load interconnection principles in PJM, the nation’s largest electricity market, “where data center development has been stymied by disagreements and uncertainty over who controls the timing and nature of large load interconnections, and over the terms of any ensuing transmission service.” Constellation specifically called out utilities for excessive influence over PJM rulemaking and procedures.
Constellation’s stance shouldn’t be surprising, Peskoe told me. From the perspective of independent power producers, enabling data centers to quickly and directly work with regional transmission organizations and generators to come online is “generally going to be better for the generators,” Peskoe said, while utilities “want to be the gatekeeper.”
In the end, the fight over data center interconnection may not have much to do with data centers — it’s just one battle after another between generators and utilities.
The senator spoke at a Heatmap event in Washington, D.C. last week about the state of U.S. manufacturing.
At Heatmap’s event, “Onshoring the Electric Revolution,” held last week in Washington, D.C. every guest agreed: The U.S. is falling behind in the race to build the technologies of the future.
Senator Catherine Cortez Masto of Nevada, a Democrat who sits on the Senate’s energy and natural resources committee, expressed frustration with the Trump administration rolling back policies in the Inflation Reduction Act and Infrastructure Investment and Jobs Act meant to support critical minerals companies. “If we want to, in this country, lead in 21st century technology, why aren’t we starting with the extraction of the critical minerals that we need for that technology?” she asked.
At the same time, Cortez Masto also seemed hopeful that the Senate would move forward on both permitting and critical minerals legislation. “After we get back from the Thanksgiving holiday, there is going to be a number of bills that we’re looking at marking up and moving through the committee,” Cortez Masto said. That may well include the SPEED Act, a permitting bill with bipartisan support that passed the House Natural Resources Committee late last week.
Friction in the permitting of new energy and transmission projects is one of the key factors slowing down the transition to clean energy — though fossil fuel companies also have an interest in the process.
Thomas Hochman, the Foundation of American Innovation’s director of infrastructure policy, talked about how legislation could protect energy projects of all stripes from executive branch interference.
“The oil and gas industry is really, really interested in seeing tech-neutral language on this front because they’re worried that the same tools that have been uncovered to block wind and solar will then come back and block oil and gas,” Hochman said.
While permitting dominated the conversation, it was not the only topic on panelists’ minds.
“There’s a lot of talk about permitting,” said Michael Tubman, the senior director of federal affairs at Lucid Motors. “It’s not just about permits. There’s a lot more to be done. And one of those important things is those mines have to have the funding available.”
Michael Bruce, a partner at the venture capital firm Emerson Collective, thinks that other government actions, such as supporting domestic demand, would help businesses in the critical minerals space.
“You need to have demand,” he said. “And if you don’t have demand, you don’t have a business.”
Like Cortez Masto, Bruce lamented the decline of U.S. mining in the face of China’s supply chain dominance.
“We do [mining] better than anyone else in the world,” said Bruce. “But we’ve got to give [mining companies] permission to return. We have a few [projects] that have been waiting for permits for upwards of 25 years.”
