Nuclear Energy’s Revival Amidst Growing Electricity Demand

In recent years, nuclear energy has experienced a renewed interest due to increasing electricity demand. The global shift towards renewable energy sources began after the Fukushima disaster in 2011. This event altered perceptions of nuclear energy, leading many countries to reduce their reliance on it. However, as electricity consumption continues to rise, particularly from data centres and artificial intelligence, nations are reconsidering their nuclear energy strategies.

Historical Context of Nuclear Energy

Nuclear energy production saw growth from the early 1970s to the turn of the century. Production rose from approximately 200 terawatt-hours (TWh) to 2500 TWh. The number of operational reactors increased from 84 to 435. This growth positioned nuclear energy as a clean and reliable power source. However, the Fukushima disaster in 2011 raised serious concerns about safety and long-term consequences.

Impact of the Fukushima Disaster

The Fukushima disaster resulted in the deaths of 51 individuals and displaced around 164,000 residents. It also caused widespread radioactive contamination. In response, many countries, including Japan and Germany, shut down or planned to phase out their nuclear reactors. This marked shift in the global energy landscape, steering investments towards renewable energy sources.

Investment in Renewable Energy

Between 2010 and 2019, global investment in renewables reached $2.5 trillion. Solar and wind energy investments surged, with $131 billion in solar and $138 billion in wind energy in 2019 alone. In contrast, nuclear energy investments averaged only $30 billion annually during the same period. Consequently, solar and wind electricity production soared, while nuclear energy production stagnated.

Renewed Interest in Nuclear Power

As electricity demand escalates, countries are revisiting nuclear energy. France plans to construct eight new nuclear power plants. South Korea has reversed its previous phase-out decision. India and the UK are investing in Small Modular Reactors (SMRs). India aims for 100 GW of nuclear capacity by 2047, with a recent budget allocation of Rs 20,000 crore for SMRs.

Role of Technology Companies

Major technology companies are also investing heavily in nuclear energy. Amazon, Google, Meta, and Microsoft are partnering with nuclear developers. Amazon’s investment approaches $1 billion, while Microsoft’s partnership with Constellation Energy involves around $1.5 billion. This collaboration marks the tech industry’s recognition of nuclear energy’s potential to meet rising electricity demands.

Electricity Demand Drivers

The exponential growth of electricity demand is primarily driven by data centres and artificial intelligence. The US Energy Department reports that electricity consumption by data centres tripled over the last decade. Projections indicate that this demand will double again by 2028. As more countries invest in AI and data centres, the pressure on electricity supply continues to increase.

Global Energy Goals and Nuclear Revival

The ambitious Paris Agreement of 2015, aiming for net zero emissions by 2050, is factor in the revival of nuclear energy. Experts argue that to meet these targets, all clean energy resources, including nuclear, must be deployed. The urgency to balance renewable energy growth with rising electricity demands puts stress on the critical role of nuclear power in future energy strategies.
