Definition and Basics
- Nuclear energy is produced through the process of nuclear fission or fusion.
- It is considered a low-carbon energy source, crucial for reducing greenhouse gas emissions.
- Plays a significant role in addressing global energy demands.
Advantages of Nuclear Energy
- Generates a large amount of energy from a small quantity of fuel.
- Operates with low emissions, helping to combat climate change.
- Provides reliable and consistent energy supply compared to solar and wind energy.
- Reduces dependency on fossil fuels, contributing to energy security.
- Requires less land compared to renewable energy installations like solar farms.
Role in Sustainable Development
- Supports the achievement of Sustainable Development Goal (SDG) 7 - affordable and clean energy.
- Contributes to SDG 13 (climate action) by mitigating carbon emissions.
- Enhances energy diversity, ensuring stable energy supplies during transitions to renewables.
- Can be integrated into hybrid energy systems alongside renewable energy sources.
Challenges of Nuclear Energy
