The Global Energy Transition Has Begun — But India’s Energy Security Challenge Remains

The year 2025 may be remembered as one of the most important turning points in modern energy history. For the first time ever, the growth in global electricity demand was met almost entirely through renewable energy sources instead of fossil fuels. This development marks not merely a technological achievement but a structural transformation in the global economy, geopolitics, climate policy, and energy security architecture.

According to the Ember Energy Institute, global electricity generation increased by around 850 terawatt-hours (TWh) in 2025. Almost the entire increase came from:

solar energy,
wind energy,
and other renewable sources.

At the same time:

coal generation declined,
oil-based generation fell,
and fossil fuel dependence stagnated globally.

This is historically significant because, for nearly two decades, renewable energy grew rapidly but never fast enough to fully replace fossil fuels. Electricity demand always rose faster than renewable supply. Thus, coal and gas continued to dominate energy systems even while renewables expanded.

In 2025, this pattern changed for the first time.

Why Is 2025 a Historic Energy Turning Point?

For most of the 21st century:

renewable energy expanded,
but
fossil fuel use also continued to rise.

The reason was simple:

developing economies needed enormous electricity for industries, urbanisation, transportation, and rising living standards.

Thus:

renewable energy added capacity,
but could not reduce total fossil fuel generation in absolute terms.

However, 2025 changed this global trend.

Solar energy alone contributed:

636 TWh of additional electricity.

Wind energy contributed:

204 TWh.

Meanwhile:

coal generation fell by 67 TWh,
and oil generation declined by 12 TWh.

This indicates that renewable energy is no longer merely “supplementary”; it is beginning to replace fossil fuels structurally.

What Enabled This Transition?

Several technological and economic developments made this shift possible.

1. Rapid Decline in Renewable Energy Costs

Over the past decade:

solar panels became dramatically cheaper,
wind turbine efficiency improved,
and installation costs reduced sharply.

Renewable electricity became economically competitive with coal and gas in many regions.

2. Advances in Battery Storage

One major criticism of renewable energy has always been intermittency:

solar energy depends on sunlight,
wind energy depends on weather.

Recent improvements in battery storage technologies have helped solve this issue by:

storing excess electricity,
stabilising supply,
and improving reliability.

3. Smarter Electricity Grids

Modern “smart grids” can:

distribute electricity efficiently,
manage fluctuating renewable supply,
and integrate multiple clean energy sources simultaneously.

This has significantly improved the viability of renewable-heavy systems.

China’s Renewable Revolution

China emerged as one of the biggest drivers of the global transition.

For the first time since 2015:

China’s fossil fuel electricity generation declined.

This is remarkable because China:

is the world’s largest energy consumer,
largest coal consumer,
and largest emitter of greenhouse gases.

Yet in 2025:

clean energy generation in China grew by 15%,
solar energy expanded by 40%,
and wind energy increased by 14%.

Most importantly:

solar energy alone met nearly two-thirds of China’s additional electricity demand.

This signals that even industrial superpowers are now moving toward renewable-led growth.

India’s Energy Transition: Progress with Contradictions

India also experienced a decline in fossil fuel generation in 2025.

Coal-based electricity generation:

fell by 3.3%.

India’s renewable capacity has grown by more than:

210% in the last decade.

In FY 2024–25:

renewable energy accounted for 89% of all new electricity capacity additions.

India is now among the fastest-growing renewable energy markets globally.

Government initiatives such as:

solar parks,
green hydrogen missions,
rooftop solar,
wind corridors,
and renewable auctions

have accelerated the clean energy transition.

However, despite this impressive growth, India continues to face a deep structural problem:

energy import dependence.

India’s Energy Security Problem

India remains heavily dependent on imported fossil fuels.

Current import dependence:

Fuel	Import Dependence
Crude Oil	89%
Natural Gas	47%
Coal	26%

This creates a major strategic vulnerability.

Even though renewable electricity capacity is increasing rapidly:

transport,
heavy industries,
cooking fuel,
and petrochemicals

still depend heavily on imported fossil fuels.

Thus:

renewable growth has not yet translated into full energy independence.

Strait of Hormuz Crisis: A Wake-Up Call

The vulnerability became clear during the closure of the:

Strait of Hormuz

following tensions involving:

Iran,
the United States,
and Israel.

The Strait of Hormuz is one of the world’s most important maritime chokepoints.

A large proportion of global:

oil,
LNG,
and gas shipments

pass through this narrow route.

India imports most of its oil from:

Saudi Arabia,
UAE,
and Qatar.

Thus, the closure immediately affected India’s energy supply.

Immediate Effects on India

1. Crude Oil Imports Fell

India’s crude oil imports declined sharply in March 2026.

2. Oil Prices Surged

The Indian crude basket price rose:

from about $72 per barrel in March 2025
to
over $113 per barrel in March 2026.

This was a massive 56% increase.

3. LPG Prices Increased

Cooking gas cylinder prices increased by:

₹60 per cylinder.

This directly affected household budgets.

4. LNG Imports Increased

India increased LNG imports despite global disruptions in order to maintain domestic supply.

India’s Emergency Response

The crisis showed that fossil fuel infrastructure still remains essential during emergencies.

India responded by:

maximising coal plant output,
increasing refinery utilisation,
accelerating LNG imports,
and supporting oil marketing companies financially.

The government reportedly provided:

₹30,000 crore support to oil marketing companies.

This demonstrates an important lesson:

renewable energy transition does not eliminate short-term fossil fuel dependence immediately.

Renewable Capacity vs Energy Security

One of the most important analytical distinctions for UPSC aspirants is:

Renewable capacity is not the same as energy security.

Renewable infrastructure:

takes years to build,
requires storage systems,
and depends on grid integration.

But geopolitical crises happen instantly.

When the Strait of Hormuz closed:

India could not wait for future solar farms or battery networks.

It had to rely immediately on:

coal plants,
LNG imports,
and existing fossil fuel systems.

This reveals the complexity of real-world energy transitions.

Geopolitics of Energy

Energy today is deeply linked with:

geopolitics,
trade routes,
strategic chokepoints,
and international conflicts.

For India:
West Asia remains strategically vital because:

a majority of oil and gas imports originate there.

Thus:

instability in West Asia directly impacts India’s economy,
inflation,
fiscal health,
and energy security.

Environmental Importance of the Transition

The decline in coal and fossil fuel use is crucial for fighting:

climate change,
air pollution,
and carbon emissions.

Coal remains the largest contributor to:

greenhouse gas emissions globally.

Thus, the shift toward renewables supports:

Paris Climate Agreement goals,
sustainable development,
and environmental protection.

Major Challenges Ahead

Despite progress, the renewable transition still faces major obstacles.

A. Intermittency

Solar and wind remain weather-dependent.

B. Storage Constraints

Battery systems are still expensive and limited.

C. Infrastructure Gaps

Renewables require:

modern transmission systems,
smart grids,
and huge investments.

D. Import Dependence for Technology

India still imports many:

solar modules,
lithium batteries,
and critical minerals.

Thus, technological self-reliance remains important.

Conclusion

The year 2025 marked a historic turning point in the global energy transition. For the first time, renewable energy met rising electricity demand without requiring increased fossil fuel generation. Countries like China and India are leading this clean energy expansion at unprecedented speed.

However, India’s experience during the Strait of Hormuz crisis highlights a critical reality:

clean energy growth and fossil fuel dependence currently coexist.

India therefore faces a dual challenge:

accelerating renewable energy transition,
while simultaneously
ensuring short-term energy security.

The future of India’s energy policy will depend on balancing:

sustainability,
affordability,
strategic autonomy,
and resilience against geopolitical shocks.

Ultimately, true energy independence will require not only renewable expansion, but also:

advanced storage systems,
diversified import sources,
strategic reserves,
green hydrogen,
and domestic manufacturing capability.
