Nuclear Energy
In a nuclear reactor, the nuclear energy stored in atoms’ nuclei is released as kinetic energy. Some of this kinetic energy heats up graphite which then heats up a fluid (like water). This creates steam and rotates a turbine, which turns a generator.
Advantages
- No greenhouse gas emission, so no contribution to global warming.
- Reliable, on-demand electricity.
Disadvantages
- Disposal of nuclear waste with a very long half-life can cause serious safety issues.
- Widespread and long term damage if an accident occurs.
