India's Renewable Energy Capacity Outlook for 2025

The question asks about the renewable energy source expected to possess the largest installed capacity in India by the year 2025. Installed capacity refers to the maximum power output a generating station can produce under normal conditions. In India, several renewable energy sources are being developed, but some are growing much faster than others.

Analyzing Key Renewable Energy Sources in India

Let's look at the main contenders:

• Solar Energy: This sector has seen exponential growth in India, driven by government initiatives like the National Solar Mission, falling equipment costs, and favorable policies. India has set ambitious targets for solar power deployment.
• Wind Energy: Wind power is another major contributor to India's renewable energy mix. While installations have been significant, the growth rate has faced some challenges compared to solar in recent years.
• Hydro Power: Large-scale hydro projects contribute a substantial amount of electricity, but new large projects face environmental and land acquisition challenges, slowing down capacity addition compared to solar and wind.
• Geothermal Energy: Geothermal energy potential in India is still largely underdeveloped and is not a significant contributor to the installed capacity.

Projected Trends for 2025

Based on current trends and government targets leading up to 2025:

• Solar energy capacity additions have consistently outpaced other renewable sources.
• Policies and incentives strongly favor solar power development across utility-scale and rooftop segments.
• While wind energy remains important, its growth rate has generally been lower than solar in recent years.
• Considering the rapid expansion and targets, Solar energy is widely projected to become the renewable energy source with the largest installed capacity in India by 2025.

Therefore, among the given options, Solar energy is identified as the leading source based on projected installed capacity for 2025.
