Editorial Summary The 2026 Strait of Hormuz disruption produced an unprecedented outcome — global fossil power generation fell 1% year-on-year in March 2026, with renewables expanding to offset the shortfall. Solar and wind capacity additions in 2025 now generate roughly twice the energy previously transported through the disrupted strait. This validates renewables as strategic energy-security infrastructure, though the buffer is incomplete for transport, petrochemicals, and aviation — where hydrogen and EVs remain the long-term answer.
The Shift in Numbers
| Indicator | 2025 | March 2026 (post-Hormuz) |
|---|---|---|
| Global fossil power generation | Baseline | −1% YoY |
| Global solar capacity additions (annualised) | ~330 GW | Continued expansion |
| Global wind capacity additions | ~115 GW | Continued |
| Global clean-energy investment | ~$2 trillion | Rising |
| Global fossil-fuel investment | ~$1 trillion | Moderating |
| Strait of Hormuz oil flow (normal) | ~20 million bpd | Disrupted 60%+ during peak crisis |
The Global Picture
IEA “Renewables 2025” Key Findings
- Renewables now provide ~35% of global electricity
- Solar alone: ~7% of global electricity (doubling every 3-4 years)
- Capacity additions in 2025 broke all prior records
- China leads: ~240 GW of the 2025 450 GW total
- USA: ~50 GW; EU: ~50 GW; India: ~30 GW
The EU’s REPowerEU Maturity
Launched May 2022 post-Ukraine invasion, REPowerEU targeted:
- 45% renewables by 2030 (up from 40%)
- 30 GW North Sea offshore wind by 2030
- Fossil-gas-to-renewables substitution in heating
- 15% cross-border electricity interconnection target
By 2026, implementation has produced:
- EU renewable share at ~48% of generation (ahead of target)
- LNG capacity doubled; but renewables growing faster
- Cross-border trade shielded countries without direct Hormuz exposure
India’s Contribution
Current Capacity (end-FY 2025-26)
| Segment | Capacity |
|---|---|
| Solar | ~120 GW |
| Wind | ~48 GW |
| Hydropower | ~47 GW |
| Nuclear | ~8 GW |
| Other RE (biomass, small hydro) | ~11 GW |
| Total non-fossil | ~234 GW (~48% of installed capacity) |
| 2030 target | 500 GW non-fossil; 50% of energy mix |
PM Surya Ghar Muft Bijli Yojana
Launched February 2024, targets:
- 1 crore (10 million) rooftop solar households by March 2027
- Subsidy: up to ₹78,000 per household for 3 kW systems
- Free 300 units/month for beneficiary households
- Cumulative capacity target: 30 GW rooftop
As of April 2026: ~60 lakh registrations, ~12 lakh installations
National Green Hydrogen Mission
Launched January 2023 with ₹19,744 crore outlay:
- 5 MMT/year green hydrogen target by 2030
- Strategic Interventions for Green Hydrogen Transition Programme (SIGHT)
- Subsidies for electrolyser manufacturing + green H₂ production
- Pilot projects in refinery feedstock substitution, steel, shipping, long-haul transport
The Incomplete Buffer
Transport Gap
- 60% of India’s crude oil demand is for transport fuels (petrol, diesel, ATF, bunker)
- Renewables don’t directly substitute — requires EV adoption or synthetic fuels
- India’s EV adoption: 7-8% of new car sales; 20%+ for 2W (2024-25 data)
- Heavy transport (trucks, buses) EV transition: 1-2% currently
Petrochemicals and Aviation
- Crude oil feedstock for plastics, chemicals, aviation fuel — no near-term electric substitute
- Sustainable Aviation Fuel (SAF) is nascent: <0.5% of current aviation fuel
Reality Check
Even at full 2030 renewable targets, India’s crude oil demand would remain significant (~5 mbpd vs current 4.7 mbpd). The Hormuz buffer is real — but only for electricity. Transport and industrial sectors need parallel hydrogen + EV + SAF transitions.
What the Episode Proves — And What It Doesn’t
Proves
- Renewables can buffer electricity-sector shocks
- Long-term investment ($2 trillion vs $1 trillion) is shifting toward clean energy
- Grid interconnection matters for shock absorption
- Storage technology is improving (batteries, pumped hydro)
Doesn’t Prove
- Full decoupling from fossil fuels
- Transport/industry shock absorption
- Price stability for developing economies
- Energy sovereignty for single-country grid disruptions
India’s Strategic Path Forward
- Renewable capacity — maintain 500 GW by 2030; accelerate transmission infrastructure (Green Energy Corridor Phase II)
- Green hydrogen — meet 5 MMT target; prioritise refinery feedstock + steel + shipping
- EV transition — PLI-ACC batteries + FAME III; target 30% car sales by 2030
- SPR expansion — Phase 2 completion, plan Phase 3 for 45-day equivalent
- Supplier diversification — reduce Hormuz-route dependence via Russia, USA, Brazil, Guyana, Africa
- Nuclear expansion — 100 GW by 2047 (NITI Aayog target)
