Not sure

[khalil]

From Study design:

comparison of energy sources: types, uses and sustainability of sources including brown coal,
natural gas, nuclear fi  ssion and biochemical fuels;

So does that mean we dont have to know about tidal, wind. etc energy sources?

Also can someone just outline types of nuclear fission. I've got no idea

[d0minicz]

Types of nuclear fission:
- Uranium-235
- Uranium-238 (not directly used, but instead capture a neutron and become uranium-239 which decays to plutonium-239)
- Plutonium-239
