Big Tech, New Energy

Alex Rivera 4

Alright, so, Emily, this is a huge story to kick things off for the new year: Google is about to acquire Intersect for nearly 4.75 billion dollars. I mean, I don't think we can overstate how big this is for the U.S. data center and renewable energy space. Intersect’s been co-locating data centers right alongside new renewable power, and now Google wants to do this at hyperscale. It’s classic “move fast, build big,” you know?

Emily Nguyen 4

Yeah, it’s wild. And what stands out to me is that they're not just buying a company for gigawatts of new power—they’re buying expertise and this whole “co-location” strategy for integrating power and digital infrastructure. That’s actual acceleration of the renewable build-out at the speed big tech needs for AI and cloud growth. The deal brings the Intersect team plus a pipeline of both energy and data center projects in development. So, from the business side, Google is locking in capacity and talent simultaneously.

Alex Rivera 4

Exactly, and it’s not just about adding capacity fast—it's about controlling when and where new generation comes online, so you’re not just waiting for grid upgrades.

Emily Nguyen 4

I want to bring up integration, because Google isn’t just investing in power—they’re exploring emerging technologies as part of this partnership: advanced geothermal, gas with carbon capture, long-duration storage. They’ll be running these experiments side-by-side with next-gen data centers, like their project in Texas. Honestly, it puts them in a really strong position not just to meet their own needs, but maybe to influence innovation for the entire sector.

Alex Rivera 4

Yeah, and you know, Intersect’s going to operate under its own brand—even as part of Alphabet—so their team keeps focus but benefits from Google’s deep pockets. This is a play to be more nimble in project delivery, and keep a front-row seat to every new innovation in grid, storage, and renewable deployment. Wild times in the infrastructure business.

Emily Nguyen 4

You know, it’s easy to see why Google’s betting so big when you look at what the International Energy Agency’s been reporting. Electricity demand from data centers and AI specifically is exploding. We’re talking about global data center electricity demand rising from around 460 terawatt-hours in 2024 to over a thousand terawatt-hours by 2030. Nearly doubling—just in the next six years.

Alex Rivera 4

Yeah, and the U.S. leads the pack, which is both exciting and, uh, a bit stressful. Most of those new data centers are AI-focused and can consume the same energy as, like, entire cities. In fact, some of these “hyperscale” AI centers are being built to handle demand that's, no joke, twenty times bigger than a typical center. It’s like, who even imagines that scale?

Emily Nguyen 4

And regionally, the energy mix is kind of a patchwork. In the U.S. and China, data centers still get most of their juice from fossil fuels. In the U.S., natural gas is the biggest source—over 40% of data center electricity. Renewables sit around 24%, but they are growing. Then China—coal is king for now, about 70% for their data centers. It’s a pretty staggering number.

Alex Rivera 4

It's wild. Meanwhile, Europe and Japan are further along—by 2030, renewables and nuclear are supplying most of their data center power. But here in the U.S., even as Google and other tech companies build more onsite renewables, rising AI demand keeps natural gas solidly in the mix. If anything, the IEA says natural gas and coal will meet over 40% of additional demand for the next five years. And for all the talk about pushing toward 100% renewables, there’s still this friction, right?

Emily Nguyen 4

Right, because renewables are scaling fast—especially wind and solar, which are expected to meet nearly half of future growth. But the pace can be uneven. Companies like Intersect, and now Google, are trying to smooth that out by building load and generation together, but with how quickly AI is ramping up, fossil capacity is sort of a safety net right now. Not to mention all the new tech, like small modular reactors, which might come into play after 2030. But that’s a bit further down the road, assuming they deliver on cost and reliability.

Alex Rivera 4

I keep thinking—honestly, this feels a lot like what we talked about in our episode on energy security a little while back. Data center growth changes the energy landscape not just nationally but regionally. Grid operators have to plan for these massive new loads, and, if the supply can’t keep up, you end up with bottlenecks, rising emissions, or even, like, project delays.

Emily Nguyen 4

So taking all that into account, here’s the paradox: nearly half of new data center demand globally is being met by renewables—that’s no small feat. But the other half, realistically, is still coming from fossil fuels and, increasingly as we look forward, small modular nuclear and advanced geothermal, especially for reliability and baseload. It’s an “all of the above” moment, even as everyone is pushing for green.

Alex Rivera 4

Yeah, you kinda have to see it as a balancing act. If you go all-in on renewables without grid upgrades or storage, you’ll face reliability issues. But if you just lean too heavily into fossil, you wreck emissions targets. There’s also that bit about grid congestion, which the IEA warns could put 20% of planned data center projects at risk of delay. And then you have these complex supply chains for things like gallium—chips need it, China supplies nearly all of it, and if demand for AI chips spikes? You can see the headache coming.

Emily Nguyen 4

That’s true, and what’s kind of amazing to me is how AI is both the driver of the problem and part of the solution. I mean, AI’s energy hunger is what’s pushing the need for more power, but it’s also helping optimize the entire system. For example, AI-driven grid optimization—like using machine learning to predict loads and integrate more renewables efficiently—can unlock huge flexibility gains. Remote sensing, predictive maintenance, even identifying grid faults in real time can cut outage durations massively. The IEA says, if we scale these digital tools, we could free up enough capacity without even building new lines. But it’s still early days—adoption, regulations, and investment all have to converge.

Alex Rivera 4

Yeah, and, I mean, I love that optimism, but policy and markets haven’t caught up yet. Utilities and developers are still figuring out how to finance these next-gen projects, and who takes the risk if, say, SMRs aren’t ready by 2030? Or if the chip supply gets squeezed again? There’s also the plain fact that emissions from data center electricity are set to peak around 2030 and then decline only slowly unless something major changes. So it’s not a slam dunk for climate goals just yet. We’re kind of stuck in this transition period—huge innovation, but also huge uncertainty.

Emily Nguyen 4

Yeah, and just to tie this back to our broader podcast themes, it's similar to what we've seen in past episodes—everything from the challenge of scaling the workforce to the complexity of upgrading supply chains for renewables. Decarbonizing digital infrastructure isn't a straight path. But the lessons learned—about collaboration, investment, and adaptability—really do apply across the energy transition, wherever you look.

Alex Rivera 4

Totally agree. It's gonna be a bumpy ride but an exciting one. And honestly, the only way is forward. Emily, anything else you want to throw in before we wrap?

Emily Nguyen 4

I just want to say, this intersection of AI, big tech, and energy is evolving in real time. There are real risks, but also so much opportunity for innovation if we keep the momentum going. Thanks for a great conversation today, Alex—always fun unpacking these big topics with you!

Alex Rivera 4

Likewise, Emily. Thanks everyone for listening to Digest This: Unpacking Our Sustainable Future. We’ll be back soon with more on what’s shaping the world of renewables and sustainability. Take care!
