India’s Energy Transition Is Complicated, But Progressing

What does an energy transition mean, and why is India trying to expand clean energy while still using large amounts of coal?

An energy transition is a shift from fossil fuels toward cleaner energy sources, such as solar, wind, hydro and nuclear power. It matters because energy systems shape emissions, reliability and economic growth. India is trying to change its power system without slowing electricity access or industrial development. Coal remains important because clean capacity does not yet generate enough power when people need it most.

India reached its Paris pledge of 40 percent non-fossil installed capacity in 2021, nearly a decade early. It then raised the target to 50 percent and crossed it in June 2025, five years ahead of schedule. Yet thermal power still produces around 70 percent of electricity. This shows the difference between building capacity and replacing coal generation.

India’s transition is therefore happening on two tracks. Clean capacity is expanding rapidly, but rising demand, weak storage and unfinished transmission keep coal central to reliable supply. The country is attempting to grow its economy and clean its energy system at the same time.

How much clean-energy capacity has India added, and what share of its installed power capacity now comes from non-fossil sources?

India added a record 55 gigawatts of clean capacity during the 2025–26 financial year. By July 2026, its non-fossil energy capacity had passed 300 gigawatts. That total represented more than half of the country’s installed power capacity. India also ranked third worldwide for installed renewable energy.

The figures measure capacity, or the maximum amount power plants can produce under suitable conditions. They do not mean that clean sources supplied more than half of all electricity throughout the year. Solar panels, wind turbines and other non-fossil plants produce power only when their resources are available, while coal plants can run more continuously.

The scale marks a major change in India’s power system. Renewables supplied more than half of electricity demand on July 29, 2025, another record. Still, the country added clean capacity while total demand continued rising, so coal remains important to meeting dependable electricity needs.

Why can non-fossil sources make up more than half of India’s installed capacity but produce less than one-third of its electricity?

Installed capacity is the potential output of power plants, not the electricity they actually generate. Non-fossil sources can occupy more than half of India’s capacity while producing less than one-third of its electricity because solar and wind depend on weather and time. Their equipment may be available but not producing at full strength.

Solar output peaks in the afternoon, while electricity demand often peaks in the evening. India therefore needs storage to save daytime electricity and transmission networks to move power across regions. Those systems are still being built. Coal plants can supply power more steadily, making them the backbone of reliability while flexibility remains limited.

This capacity-generation gap explains why India’s coal use has not fallen in line with its clean-energy buildout. On July 29, 2025, renewables did meet more than half of demand, showing what is possible. But closing the gap requires more grids, storage and flexible power management.

How are rising electricity demand, economic growth, urbanization, and heatwaves affecting India’s emissions even as its power mix becomes cleaner?

A cleaner power mix does not automatically reduce total emissions when the country uses much more electricity. India’s rapid economic growth is expanding industrial and commercial demand. Urbanization adds homes, transport needs and cooling loads. More frequent heatwaves also increase electricity use, especially for cooling. These forces raise the amount of power the system must supply.

Clean capacity is being added quickly, but demand is rising almost as fast. As a result, new solar, wind and other non-fossil plants can reduce the emissions intensity of electricity without reducing total fossil-fuel generation. Coal remains necessary when clean output is unavailable or when demand exceeds renewable production.

This is why India recorded the world’s largest absolute rise in emissions in 2024, even while its power mix became cleaner. The trend suggests that progress should be judged by both the speed of clean-energy growth and the continuing increase in total energy use. Storage, grids and efficiency will matter as demand keeps expanding.

What role do electricity grids, battery storage, and other forms of flexibility play in reducing India’s dependence on coal for reliable power?

Electricity grids and storage make variable clean energy more useful. Stronger transmission can move electricity from regions with abundant sun or wind to places with higher demand. Batteries can store surplus daytime solar and release it during evening peaks. Other flexibility, including responsive demand and adaptable power plants, can also balance changes in supply and consumption.

India’s current mismatch is clear: solar output peaks in the afternoon, while demand often peaks in the evening. Without storage, the system needs dependable backup, and coal currently provides much of it. Completing grid and storage networks would allow more clean capacity to produce electricity when consumers need it rather than only when weather allows.

These investments could reduce coal’s role in reliable supply, but they require substantial finance and have long payback periods. The article identifies grids and storage as unfinished infrastructure. International support targeted at those areas could address India’s generation gap more directly than simply adding more generating capacity.

How could carbon-border rules and India’s national carbon market affect steel and aluminum exporters, especially smaller firms?

Carbon-border rules make emissions a commercial issue for Indian steel and aluminum exporters. These industries are among the hardest to decarbonize, so firms may face added costs or lose competitiveness in overseas markets. The Global Trade Research Initiative estimated that Indian exporters could need price cuts of 15 to 22 percent to remain competitive in Europe.

India’s national carbon market became operational in January 2025. It gives industry a price signal to reduce emissions. If border systems recognize domestic carbon pricing, Indian companies could face less duplication or financial pressure. That could connect domestic climate policy with access to important export markets.

The burden is uneven. Smaller firms often struggle most with measuring and reporting emissions, which are needed for carbon-border compliance. Without support, rules could hurt smaller exporters more severely. Better recognition of India’s carbon market and assistance with reporting could make the transition fairer while encouraging cleaner steel and aluminum production.

Why should a country’s climate performance be judged using its direction of travel, per-capita emissions, and historical responsibility—not just its current coal use?

Climate performance is not only a snapshot of today’s fuel mix. Direction of travel shows whether a country is rapidly adding clean energy and improving its system. India reached its 40 percent non-fossil capacity goal in 2021 and crossed 50 percent in 2025, ahead of schedule. Those milestones reveal momentum that coal-use figures alone miss.

Per-capita emissions provide a population-adjusted comparison. The article gives no per-capita figures, but the measure matters because India is expanding electricity access for 1.4 billion people. Historical responsibility matters too. Many high-income economies industrialized using coal for more than a century before shifting toward cleaner energy, while India is trying to develop and decarbonize simultaneously.

Coal remains a real concern: thermal power supplies around 70 percent of India’s electricity, and emissions are rising. A fair assessment should therefore combine current emissions, per-capita burden, past responsibility and future direction. This broader view recognizes both India’s continuing challenges and the scale of its clean-energy transition.
