Nuclear Fuels
- The main nuclear fuels are uranuim and plutonium.
- These are radio-active metals.
- Advantages - Unlike fossil fules nuclear fuels do not produce carbon dioxide or sulfur dioxide.
- Disadvantages - They are non-renewable resources.

- They work by the wind hitting them and turning the huge turbines (kinetic enegry).
- Advantages - its a renewable resource and doesnt make harmful gases, Low cost.
- Disadvatages - They are noisy and big and can spoil landscapes, They depend on the whether if there is no…
