The tech giant’s $650 million deal with Talen Energy has a lot to unpack.
When Talen Energy, which owns a 90% interest in the Susquehanna nuclear power plant in Northeastern Pennsylvania, announced it was selling a data center site adjacent to its power plant to Amazon Web Services, it raised some eyebrows in the energy world. The surprise was not because a large tech company made a big deal with a carbon-free power provider, or even that a tech company made a deal to buy power generated by a nuclear power plant. It was because Amazon was making this deal.
Amazon is a massive buyer of renewable power — it claims to be the world’s largest and says it’s responsible for 28 gigawatts of clean energy capacity — signing contracts with new wind and solar projects all over the world.
But a divide has opened up among tech giants when it comes to energy, with Amazon on one side and Alphabet and Microsoft on the other. The difference hinges on how much it matters where and when the new carbon-free power a company buys in order to match its electricity use.
What’s odd about the Talen deal is that it fits awkwardly into either approach, especially Amazon’s. Amazon does not count nuclear towards its renewable power goals, and in any case, it’s not a “new” source of carbon-free power. Instead, it allows Amazon to siphon somewhere between 480 and 960 megawatts of capacity from the 2,500 megawatt plant.
“Amazon needs power, they’re getting it at cheap rates. They don’t even want to talk about it like a climate thing,” Mark Nelson, the founder of Radiant Energy Group, told me.
In the past decade or so, technology companies have gone on a clean-power buying spree, funding new wind and solar projects all over the world. But there has been a divergence in what is thought to be the best way to go about it.
In 2019, Amazon announced a goal to add enough renewable power to the grid to match its own emissions by 2030 (since moved up to 2025) and to reach net zero by 2040.
Google has been 100% renewable in terms of buying clean power in the same amounts that it consumes since 2017. So in 2020, it set a new goal: to “run on 24/7 carbon-free energy on every grid where we operate by 2030.” This would mean not just matching total renewable purchases with total emissions, as Amazon is seeking to do, but also trying to get every hour of data center operation “matched” with an hour of renewable generation on the same grid.
Microsoft has a similar goal, and as a result, both companies have shown much more interest in nuclear power of late than is typical in the technology world.
“A huge bottleneck for growth for Amazon, Google, Microsoft, Facebook is access to constant electricity,” Nelson told me. Nuclear is a carbon-free electricity resource that can run at a steady output 24 hours a day, whereas wind and solar are both inherently variable.
Microsoft signed a deal with Constellation to supply power to data centers in Virginia and hired an official from the Tennessee Valley Authority to be its director of nuclear and energy innovations, while Microsoft founder Bill Gates and Sam Altman, the head of Microsoft-backed OpenAI have both invested in nuclear startups, as has Google.
Amazon’s approach — which it shares with several other large companies, including Meta — is not to match 24 hours of its operations with clean power bought locally, but rather to develop and purchase new wind and solar at the same scale of the power it consumes, especially in areas with dirty grids, thus matching the emissions from its consumption with the emissions reductions of new renewables projects. While a 24/7 matching approach may be naturally complementary with nuclear power, Amazon’s strategy doesn’t require it.
“We believe a focus on emissions is the fastest, most cost-effective and scalable way to leverage corporate clean energy procurement to help decarbonize global power grids at the fastest pace,” an Amazon spokesperson told me. “This includes procuring renewable energy in locations and countries that still rely heavily on fossil fuels to power their grids, and where energy projects can have the biggest impact on carbon reduction.”
Contracting out new renewable energy projects can have more bang for your buck in dirty grids, according to proponents of the Amazon philosophy, known as carbon matching. The hypothesis is that a renewable project in a fossil fuel-heavy grid will displace more dirty power than one that’s located near a datacenter in an already relatively clean grid like California or Washington State.
Princeton researchers who examined the carbon matching (Amazon) and temporal matching (Google and Microsoft) strategies argued that the carbon matching approach does not necessarily lead to more renewables — or less fossil fuels — on the grid than would have occurred in the absence of the tech companies, and thus does not actually greatly lower emissions. The temporal approach, on the other hand, can meaningfully displace fossil fuel power that would otherwise have to be on the grid to meet demand.
Nuclear advocates are clear-eyed that this deal won’t cause a new generating unit to sprout up out of the Susquehanna Valley. But they still see it as the kind of deal that can help ensure nuclear plants’ continued survival. Amazon’s $650 million buys it a 10-year agreement to purchase power from the plant, as well as “additional revenue from AWS related to sales of carbon-free energy to the grid,” which an Amazon spokesperson explained as a reference to the deal “ensur[ing] that the nuclear plant has stable revenues to continue generating clean power to the grid for the foreseeable future.”
Nelson, a passionate advocate for nuclear power, lamented the mass shutdown of nuclear power plants in the 2010s thanks to cheap natural gas knocking them out of power markets that didn’t value reliability or carbon-free energy. But now, he says, things are different.
“Now nuclear is getting valued for its climate properties, reliability, and low cost. We’re seeing nuclear plants cash in,” Nelson told me. “Long term PPAs with cold hard cash help me sleep better at night.”

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.
