An interview with architect Marc Thorpe on building a cool house powered by the sun.
Architect and Industrial designer Marc Thorpe runs a multi-disciplinary studio in New York. His innovative approach to architecture, branding and furniture design for clients including Under Armour, Moroso and Ligne Roset is rooted in the belief in an architecture of responsibility. His original designs aim to be sustainable and affordable. He recently collaborated with Stage Six (who scale social enterprise) and affordable housing social enterprise group, Échale International on a sustainable and ecologically responsible housing development in Uganda. Each home, constructed of soil bricks, has its own water tower to collect rainwater in case of drought.
I spoke with Marc about Fremont House, he and his wife’s concept home built to showcase how off-grid living can be both stylish and affordable. Our conversation has been edited for length and clarity.
What is your general architecture approach/design?
Our approach is straightforward, simple, and legible. In the case of the several homes I’ve built upstate, it’s really been more about just trying to bring some degree of taste and sophistication to the language of architecture upstate using local vernacular. But at the same time, I’m approaching it utilizing renewable technology. The short of it is to keep everything tight and local, integrate renewable tech, and push for that 100% win/win.
Marco Petrini
How did you achieve this at the Fremont House?
We wanted to test out the solar concept along with the rectilinearity of the house. How can we keep the house as passive as possible so it doesn’t lose heat and cooling?
To start, we made the entire house solar-powered. It is not tied to the grid out of the gate. So, a zero dollar energy bill. The panels are all on the roof and are designed to accommodate southern exposure. The solar powers everything — lights, internet, appliances.
We all focused on the rectilinearity of the house, which is a passive move. We used platonic forms as a square, with 90 degree angles which make for an easier opportunity to lock it up and not lose cool. It’s also naturally cross-ventilated. There is no AC in the house whatsoever.
It’s heated with a wood burning stove and an energy efficient dyson heater inside the utility room which provides heat for piping and is always maintained at 55 degrees.
In winter, we make a fire, and because it’s square, the house doesn’t lose energy. It’s easier to heat than a house with different angles. Also the house has very few windows, so we are not losing heat that way.
Marco Petrini
How did you adapt the design for different seasons? Doesn’t it get boiling hot in summer?
Summer doesn’t get boiling hot here. The house is between Roscoe and Callicoon, New York, near Lake Tana. The area stays cool and rarely gets above 80 degrees. The cross ventilation allows the heat to move through the house naturally, it rises and goes straight out the window.
It’s also possible, if you need it, to put in an electric heat pump and a mini-split would provide AC.
Your Habitable score shows … wow, you barely have any climate risk! Not even for heat! Were you aware of that when you built here?
I didn’t know this when we were building, but I always knew the climate was super moderate here. There is lots of rain, lots of sun. It’s sort of a perfect place and also gets a lot of snow.
What decisions did you take to build the Catskill House for its environment?
We mostly had to work around hot and cold.
Also the roof panels are black and the roof is black so it retains heat. And when there is snowfall on it, the black has a faster heat coefficient to warm the snow so it melts quicker. The roof also is on an angle so the snow will fall right off — a natural cleaning too.
Marco Petrini
What would you have done differently now that you are living in it?
We finished Fremont House at the end of last year. So as of December 1, it will have been one full year.
Lessons learned? Its’ a two-story. In the future, we will build a one story. There’s just an ease of access to the roof when you need to get up there. Cleaning windows on the second level is a pain.
Otherwise, everything works perfectly. In the dead of winter, the house can heat up from freezing to 70 within a few hours. It has a small footprint, only 1,000 square feet (500 up and 500 downstairs) so a fire warms the whole house.
For the next house we do in North Branch that we are building to sell, we will execute a lot of these lessons. We will use the same approach and build according to the same concepts.
What are your three top takeaways for people who want to live off grid
1. Just take the position of being autonomous. Understand that you don’t need to rely on the system, on the grid. You don’t need to rely on anything. You can take responsibility for yourself and do it on your own.
2. You don’t need to sacrifice design to have a sustainable home. There’s a stigma around some of this stuff that is unjustified. It’s possible to have a well-designed home that is fully functioning without the powers pushing fossil fuels as the only solution.
3. There are so many opportunities to get off the grid: solar, geothermal, and other technologies. It’s worth the effort.

If you want to donate to fight climate change, what’s the best way to spend your money?
For the past five years, Giving Green has been trying to find out. Each year, the nonprofit recommends a set of nonprofits that are trying to solve the climate problem effectively and efficiently, and get the world closer to decarbonization.
Giving Green, in other words, is somewhat like the climate-specific version of Givewell, an uber-utilitarian group that identifies which global charities maximize the number of lives saved per dollar spent. But it’s much more difficult— or at least much less clear — to identify which nonprofits might best fight climate change than it is which nonprofits might save the most lives through targeted interventions.
Climate change is a globe-spanning sociotechnical problem, a political quandary baked into humanity’s largest-scale engineering systems. Even when a government or technology has seemingly pushed the world forward, it can be unclear why the improvement happened, or whether, in the long run, it will make a meaningful difference. The Paris Agreement, after all, has been around for nearly a decade, the European Union’s cap-and-trade scheme for nearly two. Yet academics, experts, and politicians can (and do) disagree about whether either policy has ultimately helped — and even why they happened in the first place.
To resolve this problem, Giving Green reviews the historical record to identify philanthropic strategies that seem like they have a good shot of leading to emissions reductions. This year, it has focused on eight, including next-generation geothermal, decarbonizing aviation and marine shipping, advancing nuclear energy, and speeding the energy transition in low- and middle-income countries. Then it looks for groups that are working on those problems in time-proven ways. This year, it also started a grant fund so that it could support some of these groups itself.
I spoke with Daniel Stein, Giving Green’s director, earlier this week. Our interview has been edited and condensed for readability.
What is Giving Green’s goal with these recommendations?
The main goal — the problem we are trying to solve — is that we believe that there are lots of people who want to do something about climate, and there’s a lot of money that’s paralyzed by indecision and sits on the sidelines. So we provide a comprehensively researched guide with a systematic approach to try and determine where the high leverage points are in climate philanthropy — and by high-leverage, I’m thinking most greenhouse gas reductions per dollar.
We focus in on what we call philanthropic strategies, specific things that people could be doing. Then we find organizations working on those strategies that are doing a great job and promote them.
Can you tell me about a few of the organizations that you have chosen?
We have some that we’ve recommended for a few years, such as Clean Air Task Force. Last year, one of our big pushes was geothermal energy, and so we’ve recommended Project Innerspace, who are a big advocate for geothermal and work a lot with both private industry and the government.
Another big area of focus for us over the past few years has been heavy industry. The case for philanthropic support for heavy industry is really, really clear. Depending on what estimate you use, heavy industry accounts for roughly a quarter of carbon emissions, but something like less than 5% of philanthropic spending. There’s very little policy teeth almost anywhere in the world on industry, and basically nothing in the U.S., but there are pathways to solving it. We kind of know how to make green steel and green aluminum, and at least have ideas on concrete and plastic. There’s a lot nonprofits can do to pave the way forward in terms of: What does policy look like? How do we get from where we are today — where we kind of know the technology but no one’s using it — to a place where there’s actually supply and demand in the future? So our top recommendations for that is an organization called Industrious Labs in the U.S. and an organization called Future Cleantech Architects in Europe.
Over the past five years, I feel like I’ve seen your mission evolve and your strategies evolve. At the beginning, you recommended giving to a mix of high-end research and policy-development groups, and then also to more grassroots, movement-type groups. But over time, your set of recommendations have become much more focused on groups that are like CATF, that are providing nonpartisan, highly expert information and analysis.
I think that’s right, but it is not necessarily that we have just changed our mind on what works. I think different moments in time call for different approaches. And in those heady years leading up to the Inflation Reduction Act — where there was hope for a Democratic trifecta, and then it happened — there was a major opportunity for a left-driven, all-of-government push on climate. That was what we thought these grassroots groups were in a good position to push forward.
I think when you look back, you see groups like Sunrise having a really powerful influence. Obviously people disagree on what forces got the IRA to happen. But I really do think that you can draw a direct line from this progressive advocacy to the Democrats believing that they had to do something about climate to please their base.
But our view is that that moment has passed. Especially post-IRA, this opportunity for a more progressive-led legislative process has ended. Even if the Democrats were still in control, I think you weren’t going to get big bills like the IRA. We moved to a point where we need to focus on the wonky details of implementing these bills and then passing more technical, focused policy in the future. Our view is that in the U.S., the big opportunities have shifted to what we would call the “insider” groups. But I think that could change again, and it could change based on geography.
Are there any big climate strategies nobody is working on right now — where you identified a place where money could be spent, but you couldn’t find a nonprofit focused on it?
One of our high-level strategies is solar radiation management. That was something that was new for us this year. And within that, we would look at very specific substrategies. Should we be funding research? Should we be funding governance? And within those little sub-elements, we occasionally found stuff where we were like, wow, we really wish there was a group working on this, but we didn’t find anything.
But one of the nice things about having a [grant-making] fund this year, for the first time ever, is that we could help get things started that didn’t exist before. We’re super excited about industry, and so much industry is happening in developing countries. But when you ask, Who is focused on reducing steel emissions in Indonesia?, there were very few organizations. We made a grant to an organization called Climate Catalyst — they were already working on steel in India, and we helped them expand into emissions reduction in Indonesia.
I think some people might see your list and go, Wow, these are a bunch of high-end research and elite advocacy organizations, but what’s actually going to solve the climate crisis is local organizing.How would you reply to that?
I think that’s a reasonable point. We are open to all of these things, and we have considered them, and I think there is a time and place for grassroots approaches and activism. But looking at the historical research and our own research, I believe that the approaches that work on this are ones where the activism is tied to clear policy demands — that are good policies, that can have big, systematic decreases in emissions and seem to have some sort of feasible pathway to success.
What I’ve seen in a lot of grassroots movements in recent years are things like throwing soup at paintings, or blocking streets, which have not had this direct policy connection, and we are pretty skeptical of those approaches. But if grassroots approaches came on our radar that have a super viable theory of change to altering policy, we are very open.
This is the fifth year you’ve put out recommendations like this, right? What have you learned or changed your mind about during that time?
One of the things that’s really crystallized in our mind is that we really think the big levers are in systems. And that can mean a lot of things, but to us, it really means three things — it means policy, technology, and markets.
To solve the climate crisis, you need to change the rules of the game, such that everyday actors — people making decisions, businesses — everybody changes their behavior because some technology got cheaper, or some policy changed. We really use that to focus ourselves to think about, What are the big changes that need to happen, and how do we work backward to the actions that get us there?
So I think that might be why you see some of these more insider, techno-analysis-driven approaches. Because when you step back and you think, alright, we need this market to change in this way, or we need this technology to develop that doesn’t currently exist, and you think about how you get there, a lot of times you need advocacy to change policy, and you need research to make that policy change possible.
This year, Giving Green has recommended six top groups fighting climate change. They are:
On conditional loans, China’s emissions, and primary care clinics
Current conditions: Storm Conall brought more heavy rain and flooding to sodden England • Flash floods killed at least 20 people on Indonesia’s Sumatra island • The northern Plains will be hit with an “arctic outbreak” on Thanksgiving day.
The Department of Energy yesterday agreed to loan Rivian $6.6 billion to resume construction on its factory in Georgia, where the company will produce the upcoming R2 and R3 electric pickups. The loan is conditional, meaning it hasn’t been finalized just yet. “If finalized, the loan will support construction of a 9 million square foot facility to manufacture up to 400,000 mass-market electric sport utility vehicles and crossover vehicles,” the DOE said in a statement. “At full capacity, the EVs manufactured at the facility are expected to yield an annual fuel consumption savings of approximately 146 million gallons of petroleum.” Whether the loan will be completed before the incoming Trump administration takes over – or whether Trump would try to axe the loan – remains to be seen. The Biden administration set a goal for zero-emission vehicles to make up half of new U.S. car sales by 2030.
China’s CO2 emissions will rise slightly this year due to a surge in energy demand, according to new research published today from the Centre for Research on Energy and Clean Air. “The growth in energy consumption and electricity consumption is faster than in the transition pathways,” the report said. Even as China rapidly rolls out renewables and EVs, emissions will rise by 0.4% in 2024. Less than half – 44% – of the experts polled by CREA said China’s emissions have already peaked, or will peak next year. Two years ago, just 15% of experts believed that to be the case. And 36% of experts said China’s coal consumption has peaked, up from 20% who said that last year. China is the world’s biggest emitter of greenhouse gases, and coal is its main source of emissions.
Porsche this week joined a growing list of car manufacturers that are pumping the brakes on the shift to EVs. Instead of rolling out new EV models to accompany the luxury Taycan and Macan, Porsche now plans to produce new gas and hybrid models instead as it feels the effects of a slowdown in EV sales. “We are currently looking at the possibility of the originally planned all-electric vehicles having a hybrid drive or a combustion engine,” the company’s CFO said. “What is clear is that we are sticking with the combustion engine for much longer.” Earlier this year Porsche watered down its goal for 80% of sales to be electric by 2030.
Maine is suing oil giants Exxon, Shell, BP, Chevron, Sunoco, and the American Petroleum Institute, accusing them of knowingly deceiving the public about the role of fossil fuels in the climate crisis. It becomes the ninth state to do so. The new lawsuit claims the oil companies have long known that fossil fuels cause climate change, and that the resulting rising sea levels are especially harmful in Maine because so many of the state’s communities and industries are located near the coastline. The state wants unspecified damages from the companies as well as funds for adaptation and mitigation.
A recent study published in the journal BMC Primary Care examines how climate change is affecting primary care clinics serving “low-income and socially disadvantaged communities.” Surveys were sent to more than 400 staff members at clinics across 43 states. Nearly 85% of the staffers who responded reported that climate change – and especially extreme heat – is affecting their patients’ health. Many said extreme weather events were harming their clinic’s ability to provide care due to effects like power outages and staff shortages. About 16% of respondents said extreme weather contributed to loss or spoilage of vaccines. But just one-third of respondents said they’d spoken to patients about the increasing health risks associated with climate change, saying they had more important topics to discuss in the limited amount of time available during consultations. And 61% cited their own lack of knowledge about the connection between climate change and health. Interestingly, just 34% said politics or polarization were stopping them from bringing up climate change when discussing health risks.

Renewables accounted for 24% of electricity generation in the first three quarters of 2024, up from 22.8% in the same period last year.
Rob talks Ford and GM with BloombergNEF’s Corey Cantor. Plus, Rob and Jesse dig into the Trump transition.
It’s been a news-filled few weeks — so it’s time for a roundup. On this week’s episode of Shift Key, Rob and Jesse talk about what Trump’s cabinet selections might mean for his climate policy and whether permitting reform could still happen. Then Rob chats with Corey Cantor, senior EV analyst at BloombergNEF, about promising Q3 sales for U.S. automakers, General Motors’ turnaround, and how much the Trump administration might dent America’s EV uptake.
Shift Key is hosted by Robinson Meyer, the founding executive editor of Heatmap, and Jesse Jenkins, a professor of energy systems engineering at Princeton University.

Here is an excerpt from our conversation:
Robinson Meyer: How are you thinking about Ford and GM right now? Because they have basically totally reversed their position since the first time we started talking.
Corey Cantor: I hope I’m not too corny today, but I was thinking Missy Elliott — another New Jerseyan — “flip it and reverse it,” in terms of how people feel about Ford and GM. I think GM’s approach … don’t forget this is their second platform at the rodeo here, meaning GM had the Bolt and the Chevy Volt before it, and a good amount of experience with EVs. And really, what they were trying to do with Ultium was to build a battery and EV platform that could work with a variety of different vehicles.
And so the struggle, as we’ve outlined before, and many publications have outlined was they just couldn’t get the battery production working. They had issues with automation. They had issues with ensuring that they were setting up the necessary suppliers. And I’d say, about maybe nine months ago or so, a favorite EV journalist of mine, John Voelcker wrote in, I believe, InsideEVs, around this idea that GM had finally cracked Ultium and were finally kind of … He had got the head of Ultium at the time on record saying that they had resolved a lot of the issues, and really, you’ve seen it in the sales volume, as well as the fact that EVs like the Cadillac Lyric continue to sell pretty consistently.
Then GM ran into a software issue with the Blazer, and fixed that software issue, and that had slowed things down. And then since, really, June of this year has been off to the races. And so we’ll see how the fourth quarter goes, right? I think you don’t want to get too high on any kind of automaker, but GM is clearly in a better spot because they’re approaching making a profit on each of the EVs sold.
Now, I’ll caveat that with, we don’t know if the EV tax credit itself, you know, at the federal level, plays a role in the fact that they’ll be gross margin profitable, but that is a pretty big turning point. Because at that point, you’re no longer losing money on those EVs, and so you are kind of geared to go more high-volume. Where if you look at Ford, Ford has been losing thousands of dollars on every electric vehicle, really had not been building a platform for the current sales of the Mach-E and the F-150 Lightning, hoping to kind of just price them where they’d be losing little enough on each that they can make their bridge to that next platform.
And then earlier this fall, Ford basically announced pushing back those EV models to 2027, along with the new platform. So Ford kind of runs into the issue that we discussed on the previous conversation with Tesla, in that they’re going to have only really two EVs in the U.S. market for the next couple of years. So GM will have the Bolt back next year and some other Cadillacs. There’s a lot of exciting things on the way for GM.
