By mid-2025, India crossed a major clean-energy threshold — 190 GW of installed renewable energy capacity — marking one of the fastest energy transitions among major economies. This expansion, led by solar, wind, hydro, and bioenergy, is not just about green targets; it directly mitigates warming impacts, strengthens grid resilience during extreme heat, and supports India’s long-term climate commitments.

The Renewable Mix: A Structural Shift in Power Generation
India’s renewable portfolio is dominated by:
-
~98 GW Solar Power
-
~48 GW Wind Energy
-
Hydro and bioenergy capacity across states
Solar additions have accelerated sharply in recent years, accounting for nearly half of the cumulative installed capacity growth. As a result, renewables now contribute close to half of India’s installed electricity capacity and a rapidly rising share of actual generation.
This structural shift reduces dependence on coal — historically the backbone of India’s power supply and a major contributor to greenhouse gas emissions.
Emission Reductions: Slowing the Warming Curve
The clean-energy expansion is estimated to avoid 200–250 million tonnes of CO₂ annually by displacing coal and gas generation. This contributes significantly to India’s Nationally Determined Contribution (NDC) target of reducing emissions intensity of GDP by 45% by 2030.
The carbon footprint of grid electricity has declined:
-
From ~0.7 kg CO₂ per kWh (coal-heavy grid)
-
To below ~0.4 kg CO₂ per kWh in renewable-dominant regions
Cleaner grids help reduce local warming amplification, especially in urban areas like Delhi, where fossil fuel combustion compounds the urban heat island effect.
While renewables alone cannot reverse historical warming, they significantly slow the pace of future temperature rise under moderate emissions scenarios.
Heatwave Buffer: Stabilising Power During Peak Stress
The climate dividend of renewables became evident during the record heatwaves of 2025:
-
Summer electricity demand surged by 15–20%.
-
Daytime solar output peaked when cooling demand was highest.
-
Coal burn was reduced by 20–30% during extreme heat days in renewable-rich regions.
By preventing coal shortages and grid collapse, renewables helped maintain electricity supply for:
-
Fans and air conditioners
-
Hospitals and emergency services
-
Water pumping systems
In a country where temperatures exceeded 45°C in several regions, uninterrupted electricity supply becomes a life-saving adaptation measure.
Long-Term Climate Resilience
The 190 GW milestone also lays the foundation for:
-
Battery storage expansion
-
Green hydrogen development
-
Flexible grid upgrades
-
Climate-resilient transmission corridors
Renewables reduce exposure to fossil fuel import volatility and buffer against monsoon variability, drought-linked hydropower fluctuations, and extreme weather disruptions.
Under moderate emissions scenarios, India could cap local temperature rise within the 1.2–1.5°C band by mid-century — not eliminating climate stress, but preventing escalation into more destabilizing outcomes.
Economic and Policy Momentum
Recent policy frameworks — including green taxonomy initiatives and climate-risk financial oversight — are aligning investment flows toward low-carbon infrastructure. Budget allocations for storage and hydrogen aim to address intermittency challenges and deepen decarbonisation.
The transition is not without obstacles:
-
Land acquisition conflicts
-
Grid integration bottlenecks
-
Intermittency management
-
Storage cost barriers
Yet the direction is clear: renewables are no longer supplementary — they are becoming central to India’s development strategy.
Conclusion: Mitigation That Supports Adaptation
India’s 190 GW renewable capacity does not eliminate climate risks overnight. But it meaningfully:
-
Cuts emissions at scale
-
Stabilises grids during extreme heat
-
Reduces fossil dependency
-
Buys time for adaptation measures like cool roofs and climate-resilient agriculture
Rather than signaling climatic collapse, this milestone represents strategic mitigation — transforming energy policy into a pillar of resilience.
