  • They release Carbon Dioxide when they are burnt. Which increases global warming.

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.

Wind Energy

  • Wind turbines have huge blades thats attached to a tall tower.
  • 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…
