The story. India added 44.6 GW of solar in fiscal 2026, pushing its combined wind, solar, and hydro capacity to 257.8 GW. China dominates at roughly 2,276 GW, while the US trails at about 380 GW — reshaping which countries sit at the center of the global clean power buildout.

The bigger picture. Installed capacity shows what's been built, but the generation mix — the breakdown of where a country's electricity actually comes from — reveals how far each grid has to go. Coal still produced 1,518 TWh of India's electricity in 2024 (Ember), nearly seven times its combined solar and wind output of 225 TWh. That dependence drives India's carbon intensity — how much CO2 each unit of electricity produces — to 705 gCO2/kWh (Ember, 2024), 50% above the global average of 471. China's clean fleet is massive, yet coal generated 5,828 TWh (Ember, 2024) and its grid still emits 555 gCO2/kWh. The US, cast as lagging in the capacity race, actually runs a cleaner grid at 384 gCO2/kWh, largely because gas has displaced much of its coal. India's solar resource makes the capacity-emissions gap even starker: it averages 4.8 kWh/m²/day of solar radiation (Open-Meteo, 2025) versus 3.9 for China, meaning each panel installed in India can produce more electricity.

The tension. The capacity race and the carbon race are different contests. India and China are winning the first decisively. Whether their new renewables displace coal — rather than just powering surging demand — determines who wins the second.
