As global conflicts raise concerns over nuclear safety, it’s time India reconsiders nuclear energy not just as a weapon, but as a clean, scalable energy source. Discover why nuclear power is critical for India’s climate goals and energy security.
In light of recent tensions between India and Pakistan—including unsettling allegations about nuclear installations being targeted and worries over potential radiation leaks—the global conversation around nuclear energy has re-emerged. But sadly, it’s happening in the wrong context.
Most conversations revolve around nuclear weapons, radiation threats, and safety concerns. What often gets overlooked is the transformative potential of nuclear energy as a clean, reliable, and scalable power source—especially at a time when India faces a critical challenge: achieving its climate goals while powering a fast-growing economy.

The Global Context: From Fukushima to a Nuclear Reboot
The Fukushima disaster in 2011 triggered a global retreat from nuclear power. Japan shut down most of its reactors, Germany began phasing out its plants, and even nuclear-reliant France slowed expansion. The risks felt too high, and public trust too low.
But now, with the climate crisis accelerating and the world falling behind on clean energy targets, nuclear is being re-evaluated.
Countries are taking another look:
- Germany is debating restarting reactors
- France is investing in next-generation nuclear
- Japan is reopening its reactors
👉 Nuclear energy is quietly making a global comeback.
India’s Energy Challenge: The Gaps Are Clear
As of 2025, India’s total installed power capacity stands at around 470 GW, roughly split as:
- ~55% from fossil fuels (coal, oil, gas)
- ~45% from renewables:
- Solar (~20%)
- Wind (~10%)
- Hydro (~10%)
- Others (biomass, waste-to-energy, etc.)
Under its Paris Agreement commitments, India has pledged to:
- Generate 500 GW of renewable energy by 2030
- Ensure 50% of total energy needs come from non-fossil sources
- Achieve net-zero emissions by 2070
But several roadblocks remain:
❌ Coal
Can’t be expanded much further—due to pollution, dependence on imports, and international pressure.
❌ Hydro
Growth is limited by seismic risks, displacement concerns, and environmental damage.
❌ Solar & Wind
Despite rapid growth, face major challenges like land acquisition, expensive battery storage, and heavy dependence on Chinese tech.
👉 That leaves nuclear energy as the only large-scale, low-carbon alternative that can realistically bridge the gap between India’s climate goals and industrial energy needs.
Why Nuclear Must Be Reconsidered
Right now, nuclear energy contributes less than 2% (~8 GW) to India’s total power generation—even less than bioenergy.
But the vision is bold. Under its ‘Viksit Bharat 2047’ agenda, the government aims to scale nuclear power capacity up to 100 GW. Achieving this would require:
- Rapid deployment of Small Modular Reactors (SMRs)
- Investment in fast breeder reactors
- Leveraging India’s thorium reserves for long-term energy independence
- Building strong public-private partnerships
In fact, the 2025 Union Budget has already allocated ₹20,000 crore for SMR development. These 50–55 MW compact units can be deployed across the country—helping decentralize energy access and reduce dependence on coal.
The Indigenous Edge: India’s Nuclear Innovation
India already has significant domestic expertise:
- Proven design and operation of Pressurized Heavy Water Reactors (PHWRs)
- Successful testing of fast breeder reactors, which enable thorium usage
- Plans for over 20 new nuclear power plants across states like Tamil Nadu, Gujarat, Karnataka, MP, and Rajasthan
- International collaborations—like the Srikakulam project with the US
The government is also promoting a new initiative: ‘Bharat Small Reactors’—200–220 MW indigenous units that are modular, flexible, and safer than older models.
Conclusion: Time to Rethink Nuclear Power, Strategically
India can’t rely only on solar and wind to meet its future energy needs.
👉 Nuclear energy is not optional anymore—it’s essential.
With the climate clock ticking and energy demands rising, we need a clean, indigenous, secure, and scalable power source. Nuclear power fits the bill—and it’s already within India’s technological reach.
