Despite record-breaking growth in renewable energy, the world is falling short of climate goals. In this episode, Alex and Emily unpack why solar is surging, why systemic change is lagging, and whatâs at stake if ambition stalls.

Chapter 1
Alex Rivera 4
Hey everyone, welcome back to Digest This: Unpacking Our Sustainable Future. Iâm Alex, and as always, Iâm joined by Emily. Emily, howâs it going?
Emily Nguyen 4
Hey Alex, Iâm good! Excited to dig into todayâs topic, reviewing REN21âs latest report, the Renewables 2025 Global Status Report: Global Overview. Thereâs a lot happening in renewables right now, but itâs not all sunshine and rosesâno pun intended.
Alex Rivera 4
Yeah, exactly. I mean, if you just look at the headlines, itâs like, âRecord-breaking year for renewables!ââand thatâs true. In 2024, we saw 740 gigawatts of new renewable power capacity added. Thatâs the biggest jump ever. But hereâs the kicker: more than three-quarters of that was solar PV. So, solar is just running away with it.
Emily Nguyen 4
Right, and itâs not just big utility-scale solar farms. Rooftop solar is booming, especially in developing countries. I saw that rooftop solar grew by 22% in those markets. Itâs a real shift toward decentralized energyâpeople taking power, literally, into their own hands.
Alex Rivera 4
The opportunity is huge: lower energy bills, more resilience, and a little extra income selling power back to the grid. But, man, the obstacles are real.
Emily Nguyen 4
Thatâs such a good point. We talk about technology costs coming down, and thatâs true for solar panels, but the system around itâgrids, storage, policyâhasnât caught up. And even with all this growth, only solar is really on track to meet the global target to triple renewables by 2030. Everything else is lagging.
Alex Rivera 4
Yeah, and itâs easy to get caught up in the numbers, but if you zoom out, weâre still not moving fast enough. The REN21 report basically says, âHey, great job on solar, but the rest of the system? Not so much.â
Emily Nguyen 4
Exactly. And thatâs where things start to get complicatedâbecause itâs not just about installing more panels. Itâs about transforming the whole energy system, and thatâs where weâre hitting some real barriers.
Chapter 2
Emily Nguyen 4
So, letâs talk about those barriers. One of the biggest things that jumped out at me in the REN21 report was the explosion in trade restrictions. I mean, in 2015 there were just nine trade measures targeting renewables. Now, in 2024, itâs over 200âmore than 50 just on solar PV. Thatâs wild.
Alex Rivera 4
Yeah, and itâs not just numbers on a page. These trade restrictions are making it harder to get the parts and materials you need, especially for solar. And itâs not just about supply chains; itâs about uncertainty. If you donât know what the rules are going to be next year, are you really going to invest in a big project?
Emily Nguyen 4
Exactly. And itâs not just trade. Weâre seeing major economies actually rolling back or delaying climate policies. The US, New Zealand, the UKâtheyâve all taken steps back recently. Only 13 countries even bothered to submit updated climate commitments to the UN this year. Thatâs a pretty clear signal that ambition is stalling.
Alex Rivera 4
Yeah, and itâs not just governments. This can cause corporations to pause their transition investments. Itâs like everyoneâs waiting to see who blinks first. And meanwhile, the clockâs ticking. Itâs also a systems problem. Weâre deploying renewables in record numbers, but weâre not building the systemsâgrids, storage, planningâthat actually let us use all that clean energy. Itâs like buying a bunch of new appliances but never upgrading your electrical panel. Eventually, somethingâs gonna blow.
Emily Nguyen 4
Thatâs a great analogy, actually. And it ties back to what we talked about in our episode on grid transformation and AI innovationsâremember how California added all that clean energy, but it only worked because they invested in storage and smarter grid management? Without that, you just hit a wall.

Chapter 3
Alex Rivera 4
Alright Emily, letâs talk money. In 2024, global investment in renewables hit 728 billion dollars. That sounds huge, but itâs still less than half of what we actually needâREN21 says we need 1.5 trillion dollars a year to really transform the system. And most of that investment is concentrated in just a few places: China, the EU, the US.
Emily Nguyen 4
Yeah, and if youâre in a low-income country, itâs even harder. Financing costs can be twice as high as in developed markets. That makes it really tough to scale up renewables where theyâre needed most. And then thereâs the slow pace of electrification in sectors like heat and fuels. Those make up more than three-quarters of total energy use, but renewables only cover about 6% of that. So, weâre not just talking about power plantsâwe need to rethink how we heat our homes, run our factories, move our vehicles.
Alex Rivera 4
Yeah, and thatâs where system-wide reform comes in. REN21 is calling for long-term planning, modernizing grids, investing in storage, and making financing more accessible. Itâs not just about more solar panelsâitâs about changing the whole infrastructure. And you know, one bright spot is corporate power purchase agreements. In 2024, companiesâespecially in tech and industryâsigned up for 69 gigawatts of renewable power through PPAs. Thatâs a 35% jump from last year. This is why long-term deal for for renewables are so important. They basically guarantee stable prices and a clean supply, even with all the market uncertainty. And that stability goes both ways, for the producer and the consumer. Itâs a model that more companies should be looking at, especially as energy markets get bumpier.
Emily Nguyen 4
Thatâs a good example. And it shows how the private sector can push things forward.
Alex Rivera 4
Yeah, and I think thatâs a good place to wrap for today. Weâve got record growth, but weâre still falling short. The next steps are clear, even if theyâre not easy. Emily, always a pleasure talking this through with you.
About the podcast
"Digest This: Unpacking Our Sustainable Future" is a podcast brought to you by 3 Rivers Energy Partners, aimed at exploring the ever evolving renewable energy and sustainability landscape. Our hosts will be exploring the latest news on sustainable business practices and environmental policy. Here, we discuss, dissect, and disseminate important news and developments in renewable energy, with a focus on Renewable Natural Gas (RNG) and its role in fostering sustainable business practices.
The stakes are high. If we donât get this right, we risk losing the momentum weâve built up. I think this is why we will start to see more renewable energy projects like ours at 3 Rivers Energy Partners. By taking industrial waste to create Renewable Natural Gas, we're able lower industrial carbon emissions and create a renewable energy that can be inserted into existing infrastructure.
Emily Nguyen 4
Absolutely, Alex. You're spot on. That's exactly why our approaches like ours are so important. By capturing industrial waste streams and converting them into Renewable Natural Gas, we're not just lowering emissions; we're redefining how industries think about waste. Our method shows companies that sustainability doesn't have to mean completely overhauling existing infrastructureâit's about enhancing what's already there, turning waste into a valuable resource, and creating measurable environmental impacts, right now.
Emily Nguyen 4
Same here, Alex. And thanks to everyone for tuning in. Weâll keep unpacking these challengesâand hopefully some solutionsâin future episodes. Take care, Alex.
Alex Rivera 4
You too, Emily. And thanks to all our listenersâsee you next time on Digest This.
