Time is not our friend when it comes to climate change. The value of lowering greenhouse gas emissions today is greater than doing it in five years because every molecule of carbon we emit between now and then will accumulate in the atmosphere. You, as an individual, can’t make your utility build or buy more solar power more quickly. But you can start generating carbon-free kilowatts at home in a matter of weeks. (For more on that, check out our guide to getting rooftop solar.)
There is a heated debate among clean energy experts about the value of rooftop solar in the climate fight. Heatmap contributor and Princeton professor Jesse Jenkins argues that because big utility-scale solar installations are so much cheaper to build, rooftop solar rarely does little more than crowd out these projects, making our future clean energy system more expensive.
But as Eric O’Shaughnessy, a renewable energy market research analyst, told me, we don’t have a central planner who can wave a wand and manifest the most cost effective system. And in the real world, economics isn't the only factor determining what we build. Although the U.S. is now building more renewable energy than it has in the past, and the cost is now on par with — if not lower than — new fossil fuel generation, the clean energy industry is battling serious headwinds. A stubborn trifecta of inflation, supply chain constraints, and high interest rates has slowed utility-scale development compared to what it might have looked like. Community opposition to clean energy projects has increased and will likely worsen as the least-controversial sites for development get used up. And we simply do not have enough power lines to accommodate new clean generation — solar and wind projects are waiting years to get approval to connect to the transmission system.
All of this is becoming a problem for our climate goals. A recent Rhodium Group report found that the pace of clean energy deployment has lagged projections of what programs under the Inflation Reduction Act could be achieving — projections that already fall short of how much we should be building to meet our emissions targets. Though some of the challenges may ease — for example, the Federal Reserve just cut interest rates, which had become a significant obstacle for clean energy deployment — others are likely to take longer to resolve.
Homeowners, by contrast, can avoid land-use conflicts and act comparatively swiftly. “This is a space that's not being used,” O’Shaughnessy said. “Most people don't ever go to their roof. There’s no site acquisition. You don’t have to worry about an endangered turtle.”
The immediate emissions benefits of installing solar really depend on where you live and how dirty your local grid is, among other factors. But the reason we still put rooftop solar in the number two slot is that it’s such a high leverage climate action in other ways. For example, having a solar array can help you afford future investments in other climate solutions like heat pumps and EVs, because it mitigates against electric bill increases. It can also reduce overall electricity demand in your neighborhood, which may help your utility avoid costly grid upgrades and keep rates lower in your area.
If you pair your solar array with a battery, you may be able to join a utility program that synchronizes thousands of these systems in your region to decrease strain on the grid, avoid blackouts, and preempt the need to deploy fossil fueled “peaker” plants in periods of especially high demand. Various estimates from the Department of Energy and private research firms have found that such “virtual power plants” have the potential to save billions of dollars over the next decade. These programs will typically pay you to participate, too.
Researchers have also found that rooftop solar is “contagious” — one new installation in a neighborhood can cascade into several. “If you install solar, you are going to go through a process that most people have not,” O’Shaughnessy told me. “In doing that, you are going up this learning curve, and all of that is something that you can share with your friends, neighbors, family after the fact.”
If you’re a renter, or if you aren’t able to get rooftop solar today for some other reason, subscribing to a community solar project is another way to help speed up solar deployment in your region and reap some of the benefits that homeowners have access to. Community solar arrays are usually small installations on warehouse roofs, parking lots, or beside highways. Subscribers sign up for a portion of the electricity produced, and receive credits on their electric bills the same way they would with a rooftop system. These projects aren’t available everywhere, though. Solar United Neighbors, who we consulted for our rooftop solar guide, has more background reading and a directory of projects you can subscribe to.
(A brief note on a third option: choosing a “green” retail electricity provider. This is a much more indirect way to support the energy transition, and experts are split on whether it’s worth doing at all. In theory, it sends a demand signal for renewables and helps new projects get built, but there’s no way to really know how far your money is going. Because the benefits are not guaranteed, we are not including this option in this package.)
Getting rooftop solar can be a big, confusing project, and our guide on the subject will walk you through everything you need to know to feel prepared to tackle it.

And more of this week’s top renewable energy fights across the country.
1. Otsego County, Michigan – The Mitten State is proving just how hard it can be to build a solar project in wooded areas. Especially once Fox News gets involved.
2. Atlantic County, New Jersey – Opponents of offshore wind in Atlantic City are trying to undo an ordinance allowing construction of transmission cables that would connect the Atlantic Shores offshore wind project to the grid.
3. Benton County, Washington – Sorry Scout Clean Energy, but the Yakima Nation is coming for Horse Heaven.
Here’s what else we’re watching right now…
In Connecticut, officials have withdrawn from Vineyard Wind 2 — leading to the project being indefinitely shelved.
In Indiana, Invenergy just got a rejection from Marshall County for special use of agricultural lands.
In Kansas, residents in Dickinson County are filing legal action against county commissioners who approved Enel’s Hope Ridge wind project.
In Kentucky, a solar project was actually approved for once – this time for the East Kentucky Power Cooperative.
In North Carolina, Davidson County is getting a solar moratorium.
In Pennsylvania, the town of Unity rejected a solar project. Elsewhere in the state, the developer of the Newton 1 solar project is appealing their denial.
In South Carolina, a state appeals court has upheld the rejection of a 2,300 acre solar project proposed by Coastal Pine Solar.
In Washington State, Yakima County looks like it’ll keep its solar moratorium in place.
And more of this week’s top policy news around renewables.
1. Trump’s Big Promise – Our nation’s incoming president is now saying he’ll ban all wind projects on Day 1, an expansion of his previous promise to stop only offshore wind.
2. The Big Nuclear Lawsuit – Texas and Utah are suing to kill the Nuclear Regulatory Commission’s authority to license small modular reactors.
3. Biden’s parting words – The Biden administration has finished its long-awaited guidance for the IRA’s tech-neutral electricity credit (which barely changed) and hydrogen production credit.
A conversation with J. Timmons Roberts, executive director of Brown University’s Climate Social Science Network
This week’s interview is with Brown University professor J. Timmons Roberts. Those of you familiar with the fight over offshore wind may not know Roberts by name, but you’re definitely familiar with his work: He and his students have spearheaded some of the most impactful research conducted on anti-offshore wind opposition networks. This work is a must-read for anyone who wants to best understand how the anti-renewables movement functions and why it may be difficult to stop it from winning out.
So with Trump 2.0 on the verge of banning offshore wind outright, I decided to ask Roberts what he thinks developers should be paying attention to at this moment. The following interview has been lightly edited for clarity.
Is the anti-renewables movement a political force the country needs to reckon with?
Absolutely. In my opinion it’s been unfortunate for the environmental groups, the wind development, the government officials, climate scientists – they’ve been unwilling to engage directly with those groups. They want to keep a very positive message talking about the great things that come with wind and solar. And they’ve really left the field open as a result.
I think that as these claims sit there unrefuted and naive people – I don’t mean naive in a negative sense but people who don’t know much about this issue – are only hearing the negative spin about renewables. It’s a big problem.
When you say renewables developers aren’t interacting here – are you telling me the wind industry is just letting these people run roughshod?
I’ve seen no direct refutation in those anti-wind Facebook groups, and there’s very few environmentalists or others. People are quite afraid to go in there.
But even just generally. This vast network you’ve tracked – have you seen a similar kind of counter mobilization on the part of those who want to build these wind farms offshore?
There’s some mobilization. There’s something called the New England for Offshore Wind coalition. There’s some university programs. There’s some other oceanographic groups, things like that.
My observation is that they’re mostly staff organizations and they’re very cautious. They’re trying to work as a coalition. And they’re going as slow as their most cautious member.
As someone who has researched these networks, what are you watching for in the coming year? Under the first year of Trump 2.0?
Yeah I mean, channeling my optimistic and Midwestern dad, my thought is that there may be an overstepping by the Trump administration and by some of these activists. The lack of viable alternative pathways forward and almost anti-climate approaches these groups are now a part of can backfire for them. Folks may say, why would I want to be supportive of your group if you’re basically undermining everything I believe in?
What do you think developers should know about the research you have done into these networks?
I think it's important for deciding bodies and the public, the media and so on, to know who they’re hearing when they hear voices at a public hearing or in a congressional field hearing. Who are the people representing? Whose voice are they advancing?
It’s important for these actors that want to advance action on climate change and renewables to know what strategies and the tactics are being used and also know about the connections.
One of the things you pointed out in your research is that, yes, there are dark money groups involved in this movement and there are outside figures involved, but a lot of this sometimes is just one person posts something to the internet and then another person posts something to the internet.
Does that make things harder when it comes to addressing the anti-renewables movement?
Absolutely. Social media’s really been devastating for developing science and informed, rational public policymaking. It’s so easy to create a conspiracy and false information and very slanted, partial information to shoot holes at something as big as getting us off of fossil fuels.
Our position has developed as we understand that indeed these are not just astro-turf groups created by some far away corporation but there are legitimate concerns – like fishing, where most of it is based on certainty – and then there are these sensationalized claims that drive fears. That fear is real. And it’s unfortunate.
Anything else you’d really like to tell our readers?
I didn’t really choose this topic. I feel like it really got me. It was me and four students sitting in my conference room down the hall and I said, have you heard about this group that just started here in Rhode Island that’s making these claims we should investigate? And students were super excited about it and have really been the leaders.
