Sumant Sinha — CEO of ReNew — decodes the energy shock reshaping India, and why the smartest capital in the country is now moving on just two sectors: AI and energy.

 

India spends $150–200 billion a year importing 80–85% of its fuel, almost a third of all imports. Sumant Sinha argues that dependence is the economy's Achilles heel, and it's now colliding with a hard new reality: solar has become the cheapest form of new electricity on the planet, falling from ₹15–18 a unit fifteen years ago to ₹2.5 today, while coal-fired thermal power has climbed 30–35%.

 

We unpack the full thesis: why this energy shock is worse than every prior one, why the world is splitting into "fuel-rich" and "fuel-deprived" nations, and how India gets from 13–14% renewable generation today to 500 GW by 2030 — and an extraordinary 3000 GW by 2047 (for context, the entire US grid is 1200 GW).

 

We also dig into peak coal by 2035, why wind has stalled while solar scales, the race to build domestic manufacturing up the value chain so India doesn't trade oil dependence on the Middle East for cleantech dependence on China, and where nuclear and data-center demand fit in.
