THE CONTEXT: The global push for nuclear energy as a climate solution has gained momentum in recent years, with advocates highlighting its potential to address challenges related to climate change and energy security.


  • Despite significant advantages, such as minimal carbon footprint and perennial availability, nuclear energy faces hurdles that impede its widespread adoption.
  • We will look into the factors driving the push for nuclear energy, challenges hindering its uptake, and India’s stance on nuclear power expansion.

Advantages of Nuclear Energy:

  • Nuclear energy is lauded for its minimal carbon footprint, making it a viable alternative to fossil fuels for electricity generation.
  • The entire life cycle of nuclear power results in negligible emissions, significantly lower than coal-fired electricity and comparable to renewable sources like solar and wind.
  • Perennial availability distinguishes nuclear energy as suitable for baseload electricity generation, offering stability that intermittent renewables may lack.
  • Recognized by the IPCC, nuclear energy plays a crucial role in decarbonization pathways, contributing to substantial greenhouse gas emissions avoidance.

Challenges to Nuclear Energy Uptake:

  • Safety concerns, exacerbated by events like the Fukushima accident, contribute to apprehensions surrounding nuclear energy adoption.
  • High capital investments, prolonged construction timelines, and stringent regulations deter countries from pursuing nuclear power projects.
  • Limited technological advancements in nuclear sector compared to renewables hinder cost reductions and scalability.
  • Despite its potential, nuclear energy constitutes less than 10% of global electricity generation, with operational reactor numbers declining in recent years.

Global Push and Recent Initiatives:

  • Efforts by global nuclear advocates, including the IAEA, aim to garner greater acceptance and support for nuclear energy.
  • The IAEA’s ‘Atoms4Climate’ initiative and engagement with climate conferences highlight nuclear energy’s role in clean energy transition.
  • The Nuclear Energy Summit in Brussels underscores international collaboration to promote nuclear energy as a solution to climate challenges.
  • Despite challenges, nuclear energy remains integral to achieving net-zero emissions and addressing the climate emergency.

India’s Position on Nuclear Energy:

  • India acknowledges the role of nuclear energy in its decarbonization strategy, aiming for rapid expansion in the coming years.
  • The country plans to triple its nuclear power capacity by 2031-32, although its share in total electricity generation is expected to remain modest.
  • India’s participation in global nuclear initiatives, such as the Brussels Summit, demonstrates its commitment to nuclear energy as a clean and reliable electricity source.
  • Former officials advocate for accelerated growth of India’s nuclear sector, emphasizing its importance in meeting future energy demands.
