India's renewable energy story is moving faster than most people expected. The numbers are real — over 270 gigawatts of installed capacity, more than half the country's power now coming from non-fossil sources, ahead of the timeline that was set. But on World Environment Day, the people building that future are saying something more than just celebrating the progress. They're pointing at what's still unfinished, what the next decade actually demands, and why the gap between a target on paper and change on the ground remains the hardest problem in the room.

Shivangi Rajpopat, Group Company Secretary and Head of Sustainability at Apraava Energy, put it plainly. India has already surpassed 52% non-fossil installed capacity ahead of schedule, and NDC 3.0 commits to 60% clean power and a 47% cut in emissions intensity by 2035. "India is proving that development and decarbonisation can walk hand in hand," she says. But she's equally clear about where the next challenge sits — not just adding renewable capacity, but building the transmission infrastructure and grid flexibility to actually move that power to where it's needed. "The success of the transformation will depend not only on adding renewable capacity, but also on strengthening transmission infrastructure and grid flexibility, backed by enabling policy and regulatory interventions that ensure clean power can be efficiently evacuated, integrated and delivered to consumers at scale."

S. Basant, Managing Director of Kshema Power India, has watched this shift from the inside over more than two decades in the power sector. What's changed, he says, is not just the technology or the targets — it's the conversation itself. "Sustainability has evolved from being a long-term aspiration to becoming a critical consideration in every conversation about growth and infrastructure." His point is less about any single project and more about a broader shift in how the industry thinks. Economic progress and environmental responsibility, he argues, are no longer in tension. They have to move together, or neither moves at all. "Creating a sustainable future is not the responsibility of governments or industries alone. Every individual, every organisation, and every action contribute to the larger goal."

Wind is the part of the renewable story that tends to get less attention than solar, and Aditya Pyasi, CEO of IWTMA, thinks that needs to change. India added over 6 gigawatts of new wind capacity in FY 2024-25 — the highest annual addition in recent years. "Wind energy is central to this transition," he says. "As a cost-effective, scalable, and domestically available resource, wind power reduces dependence on fossil fuel imports while strengthening grid reliability." The untapped potential, both onshore and offshore, is significant. But realising it will require something the sector hasn't always had: consistent policy support, faster project execution, and a domestic manufacturing base strong enough to keep pace with ambition.

Anand Jain, Founder of Aerem, is focused on the financing side of the equation — the piece that often determines whether a clean energy project gets built or stays as a plan. "Green finance plays a vital role in this journey: it catalyses scale, reduces project risk, and attracts long-term capital that turns plans into operating assets," he says. Aerem develops solar, storage and distributed energy projects across urban and rural markets, and Jain's argument is that commercial ambition and environmental purpose aren't in conflict — they're the same thing, properly understood. "The future will be powered by renewables — and by the coordinated action of industry, policy and finance to make that future real."

For companies on the infrastructure side of the energy transition, the sustainability conversation looks somewhat different. Vandana Kudalkar, Senior VP of QHSE at Jyoti Structures Limited, makes a point that often gets lost when the focus stays on generation capacity alone — that how infrastructure gets built matters as much as what gets built. "With infrastructure development continuing to expand, it is important that environmental considerations remain part of how projects are planned and executed," she says. At Jyoti Structures, that means resource efficiency, environmental compliance, and a focus on consistent improvement across operations rather than one-off gestures. "Small actions taken consistently can create a meaningful impact over time." It's a quieter argument than the big capacity numbers, but it speaks to something real — the transition runs through thousands of project decisions, not just policy announcements.

Manish Dabkara, Chairman and Managing Director of EKI Energy Services and President of the Carbon Markets Association of India, takes a step back from the energy transition itself to make a point that doesn't always fit neatly into the renewable energy conversation. Nature, he says, remains the world's most efficient climate technology — and the one we've consistently undervalued. "Forests, wetlands, grasslands and oceans absorb carbon, regulate water cycles, protect biodiversity and support livelihoods at a scale no engineered solution can replicate." The cost of restoring these systems is real. The cost of losing them is higher and harder to calculate. "Governments, businesses and financial institutions must work together to channel capital towards measurable environmental outcomes." His closing point is worth sitting with: "Nature is not a stakeholder in the economy — it is the foundation upon which every economy is built."

Piyush Goyal, Co-Founder and CEO of Volks Energie, is one of the few voices willing to say out loud what the data has been showing for a while. The 1.5°C threshold — the line the world promised not to cross — is now behind us. "That fact shapes how we work at Volks Energie, and how I think about the years ahead," he says. The shift in tone is deliberate. This isn't defeatism — it's a different kind of accountability. Protecting forests prevents tens of billions of dollars in disaster losses annually, UNEP estimates. Urban green cover can lower city temperatures by as much as four degrees. "These are returns no balance sheet fully captures." What World Environment Day actually tests, he argues, is staying power — whether companies and governments hold to their commitments once the attention moves on. "For us, the answer lies in the projects we deliver, quietly, in the months between."

Taken together, what these voices describe is an industry at a genuine inflection point. The foundations have been built faster than expected. The next phase — grid infrastructure, storage, policy consistency, nature restoration, patient capital — is harder and less visible than the solar panels and wind turbines that get photographed. But it's where the transition either holds or starts to fray.
