Disadvantage of tidal power

http://bux.to/?r=tankahban

-Very expensive to build .
-Affect a very wide area - the environment is changed for many miles upstream and downstream .
-Many birds rely on the tide uncovering the mud flats so that they can feed .
-Olny provides power for around 10 hours each day , when the tide is acutally moving in or out .
-THere are very few suitable sites for tidal power stations .
