Fission and fusion
Physics · Secondary 3 · Medium · Fission and fusion
Why is it difficult to use nuclear fusion (like in the Sun) as a practical energy source on Earth?
- Fusion needs extremely high temperature and pressure that are hard to achieve and contain
- Fusion produces almost no energy compared to fossil fuels
- Fusion requires uranium fuel, which is very rare on Earth
- Fusion only occurs at very low temperatures close to absolute zero
