Introduction

India's transition towards clean energy has accelerated, with 2024 witnessing record-breaking renewable energy (RE) installations and policy innovation. With a vision to achieve 500 GW of non-fossil fuel capacity by 2030 and net-zero emissions by 2070, India is shaping itself as a global leader in sustainable development.

What is Renewable Energy?

Renewable energy is derived from naturally replenishing sources like solar, wind, hydropower, and biomass. It plays a vital role in:

• Reducing dependence on fossil fuels.
• Lowering greenhouse gas emissions.
• Ensuring long-term energy security.

India’s RE Targets and Progress

Parameter                                 Target/Status

2030 Target                              500 GW of non-fossil fuel capacity

Net Zero by                               2070

Current Status (Jan 2025)      217.62 GW of non-fossil fuel-based capacity

Short-term Goal                      50% energy capacity from renewable sources

2024: Year of Renewable Milestones

Solar Energy

• 24.5 GW added in 2024 — a 2.8x increase over 2023.
• 18.5 GW utility-scale solar: Rajasthan, Gujarat, Tamil Nadu contributed 71%.
• Rooftop Solar:
  • 4.59 GW added (↑53%)
  • 7 lakh installations under PM Surya Ghar: Muft Bijli Yojana.
• Off-grid Solar:
  • 1.48 GW added (↑182%), promoting rural energy access.

Wind Energy

• 3.4 GW added: Gujarat (1,250 MW), Karnataka (1,135 MW), Tamil Nadu (980 MW) = 98% of new capacity.

Hydropower & Others

• Existing hydropower plants modernized to improve efficiency.

Government Initiatives Driving Growth

Scheme/Initiative                                                Purpose

PM Surya Ghar: Muft Bijli Yojana                  Rooftop solar subsidies for households

Green Energy Corridor (GEC)                        Transmission infra for RE-rich states

Hydrogen Energy Mission                                Promote green hydrogen production

National Smart Grid Mission (NSGM)            Integration of variable RE sources into the grid

FAME Scheme                                                   Promote EV adoption, indirectly supporting RE usage

International Solar Alliance (ISA)                   Strengthen global cooperation in solar energy

Challenges in RE Expansion

• Land Acquisition: Resistance from locals, especially in solar park areas.
• Grid Stability: Intermittency of solar/wind leads to voltage and frequency issues.
• Storage Gaps: Lack of large-scale battery storage limits surplus utilization.
• E-Waste Concerns: Rising disposal of solar panels and batteries.
• Mineral Dependency: Import reliance on lithium, cobalt, etc.
• Regulatory Bottlenecks: Delay in approvals and lack of inter-state coordination.

Way Forward: Strategic Interventions

Technological Innovation

• Floating Solar Projects: Utilize reservoirs to save land and reduce evaporation.
• Decentralized Systems: Peer-to-peer trading via blockchain for energy democratization.
• Green Hydrogen: Use surplus RE for hydrogen fuel, develop hydrogen corridors.

Infrastructure & Manufacturing

• Renewable Energy SEZs: Promote local manufacturing and innovation.
• Smart Grid Development: Improve grid flexibility and real-time balancing.

Environmental Management

• Circular Economy for RE Waste: Design policies for solar panel and battery recycling.
• Urban Integration: Incentivize rooftop installations in urban centers.

Conclusion

India’s renewable energy revolution is at a crucial juncture. With 2024 setting a strong precedent through record installations and policy progress, the path to 2030 and beyond will require addressing infrastructural, financial, and regulatory challenges. A multi-pronged, inclusive, and technology-driven approach will help India lead the global clean energy transition.
