The energy transition alone spans critical minerals, AI data centres, nuclear energy, storage, grids, carbon management, energy security, industrial competitiveness, cooling infrastructure, and about a hundred other rabbit holes. This is no longer a conversation happening inside environmental circles. It is becoming a conversation about how economies, industries, and societies function.
I attended Let's Talk Climate expecting a conversation about climate action and storytelling. Instead, an interactive mock trial led me back to memories from hospital wards, conversations with patients and caregivers, and lessons that have stayed with me for years. The experience was a reminder that climate change is not only about emissions, policies, and science. It is also about people, communities, health, dignity, and the stories we carry long after the headlines fade.
What do uranium stockpiles, critical minerals, battery recycling, low-carbon cement, algae-based materials, data centres, and geopolitical tensions have in common?
More than most people realise.
This article explores why advanced materials may be one of the most overlooked lenses through which to understand climate action, industrial transformation, energy security, circularity, and the industries shaping the next few decades. Through personal observations from eight years in climate and sustainability ecosystems, I unpack how materials sit quietly beneath many of the conversations we treat as separate—and why the future may emerge at the intersections.
Artificial intelligence dominates headlines, investment flows, policy discussions, and boardroom conversations. Yet AI may not be the biggest technology story unfolding today. Beneath the excitement surrounding chatbots, copilots, and foundation models, a far larger infrastructure transition is quietly taking shape. Satellites are observing the planet in real time. Sensors are monitoring everything from power grids to forests. Digital twins are simulating future scenarios before they happen. Robotics are beginning to close the gap between intelligence and action. Cloud infrastructure, semiconductors, cybersecurity systems, digital governance frameworks, and digital public infrastructure are increasingly converging into something much larger than individual industries. Over the past year, while building a sustainability and future technology taxonomy spanning more than 150 domains, I realised I was not looking at separate sectors. I was looking at the emergence of a planetary operating system.
After months of evaluating startups, speaking with founders and investors, and reviewing research-led innovations, I keep encountering the same underlying challenge. The problem is rarely a lack of ideas, talent, or ambition. More often, it is a failure of translation—between capital and growth, expertise and credibility, research and market adoption. Here are a few patterns I have been noticing across startup rooms lately.
A three-hour Climate Party conversation with ProClime unexpectedly became a deep dive into invasive alien species, biochar economics, carbon market realities, ecosystem services, and the hidden operational complexity behind “high-integrity” climate projects. From tiger habitats threatened by Lantana camara to the infrastructure-heavy reality of biomass carbon credits, the discussion revealed how climate work is rarely just about carbon — it is about ecology, livelihoods, governance, biodiversity, finance, and the invisible systems connecting all of them together.
I have spent years being politically stereotyped for speaking about climate resilience, localisation, resource dependency, and mindful consumption. Too left. Too right. Too idealistic. Too cynical. But the uncomfortable reality is that ecological collapse and systemic instability do not pause themselves to accommodate political comfort or public distraction.
What does it really take to build a venture-scale company in a world that refuses to stay predictable?
In a three-hour fireside chat with Karthik B. Reddy, the discussion moved beyond frameworks and into the lived realities of founders and investors, covering everything from market sizing and team dynamics to climate tech, capital flows, and the long game of building.
I’ve been watching how the US–Israel–Iran war is playing out across global energy systems, and something doesn’t add up.
Everyone assumed that if fossil fuels became unstable, the world would naturally accelerate its shift to renewables.
But that’s not what’s happening.
What’s actually unfolding is much messier. Governments are scrambling for short-term survival, fossil fuels are becoming profitable again, and the very supply chains needed to build clean energy are under stress.
This is not a transition story.
It’s a systems stress test.
A personal observation on how climate action still ends up tied to Big Oil because of where the capital sits Last year, I was at a sustainability conference where the event was powered by the Indian Petroleum Corporation. During one…
