Global solar progress took centre stage in New Delhi this week at the 8th International Solar Alliance (ISA) Assembly, where leaders and policymakers outlined a more action-driven approach to scaling solar energy worldwide. India’s Minister for New and Renewable Energy, Pralhad Joshi, urged member nations to move from ambition to implementation, while ISA Director-General Ashish Khanna announced that renewable energy generation had, for the first time, overtaken coal globally in the first six months of 2025. Together, these milestones mark a significant turning point in the global clean energy transition.
Breakdown
Minister Pralhad Joshi called for global collaboration to move beyond declarations and deliver measurable progress in solar adoption. He Emphasized that the ISA’s mission should now focus on enabling faster project execution, supporting member countries in securing investments, and creating frameworks for equitable technology transfer. The shift reflects India’s growing role as a leader in renewable energy diplomacy and infrastructure development.
ISA Director-General Ashish Khanna highlighted a historic milestone in global energy trends, confirming that renewable energy generation surpassed coal in the first half of 2025. According to ISA’s data, it took the world 25 years to reach 1,000 GW of solar capacity, but the next 1,000 GW was added in just two years. Asia-Pacific now accounts for more than 70 percent of all new solar installations, with Africa emerging as the next growth frontier.
The ISA also outlined three key areas of focus for 2026 and beyond: expanding catalytic finance through the Africa Solar Facility, advancing regional power-grid interconnections to reduce storage dependency, and establishing the ISA Academy for capacity building and skill development in member countries. These initiatives aim to transform solar cooperation from policy frameworks into tangible results.
Why This Matters
Renewable energy surpassing coal is not a symbolic milestone but a structural shift in the global energy landscape. It demonstrates that the economics of clean energy have become more compelling than fossil fuels in both developed and emerging markets. For India, this moment also strengthens its global position as a clean energy champion, bridging technology, finance, and policy leadership through the ISA.
The emphasis on implementation signals a new phase where energy transition depends less on pledges and more on execution. As nations face rising energy demands alongside climate imperatives, India’s approach offers a model for balancing sustainability with scalability.
The Bigger Picture
The ISA, now joined by over 120 member and signatory countries, has evolved from an advocacy platform into a global alliance for real-world energy transformation. The focus is shifting toward affordable financing, cross-border energy cooperation, and the deployment of renewable infrastructure in the Global South.
India’s leadership at the ISA assembly underscores its broader clean energy strategy, expanding solar manufacturing capacity, scaling green hydrogen, and Modernizing transmission infrastructure. The fact that renewables have overtaken coal shows that the world’s energy transition is no longer theoretical. It is happening now, driven by technology, policy coordination, and private-sector innovation.
The Crunch
For business leaders and investors, the message from the ISA assembly is clear. Solar is no longer an emerging trend; it is the foundation of the next global energy system. Those who act early to invest in manufacturing, storage, electric mobility, and digital grid solutions will shape the competitive landscape of the coming decade.
As Minister Joshi put it, the challenge ahead is not whether the world will transition to clean energy, but how fast it can be achieved. The ISA’s renewed focus on action-oriented cooperation signals that the race has already begun, and leadership will belong to those who execute, not those who simply commit.
