Question

Examine the role of nuclear energy in meeting growing demand of power.

Answer 1

Role of Nuclear Energy in Meeting Power Demand:

1. Reliable Baseload Power (24/7 Supply): Unlike solar and wind energy, which are intermittent (depending on the weather), nuclear energy provides a consistent “baseload” supply. With a capacity factor of more than 90%, it keeps the grid steady even when the sun isn't out or the wind isn’t blowing.
2. Clean Energy & Decarbonisation: Nuclear is a low-carbon energy source. It emits zero CO₂ during operation, making it essential to countries pursuing Net Zero goals. It currently generates around one-quarter of the world’s clean electricity.
3. Strategic Energy Security: Nuclear power decreases a nation’s reliance on variable fossil fuel imports (such as coal and gas). Because nuclear fuel (uranium) is energy-dense, a tiny amount generates a large amount of electricity, making it easier to stockpile for future security.
4. Technological Innovation (SMRs): The development of Small Modular Reactors (SMRs) is game-changing. These are smaller, safer, and less expensive to install than conventional big plants. They can be installed in remote locations or used to power specialised industries and data centres.
5. High Energy Density for Industrial Growth: As economies grow, the demand for high-intensity power for AI, electric vehicles, and heavy industry rises. Nuclear energy is one of the few sources that can supply this high-density need on a large scale without requiring a significant amount of land.
