advantages

• tidal power does not

  cause pollution

  
• tidal power is predicted twice a day so it is

  reliable

  
• the construction of tidal power is 


  costly

  
• • These might not be near where the electricity is needed, and that

  requires miles and miles of electricity lines.

  
• • There is some potential damage to the marine environment when

  turbines are installed in large numbers.

  
• Tidal barrages affect the flow of water through estuaries,

  can alter habitats and affect migrating fish and other animals.
