There could actually be conservational benefits to the Tidal power generators too though. All they basically do is delay the tide a few hours in and out.

The small difference in level also facilitates the safe passage of salmon and other fish species through the special turbines, something that is not possible with conventional turbines with their high pressure drop and sharp edged high-speed runners (rotors). There is nothing to suggest that there should be any more risk (possibly less) from a salmon passing through a turbine than from ascending a natural obstacle of similar height in a river such as a set of rapids, with sharp rocks and high turbulence.

i  dont fear for the adult fishes, but those places are most of the time the ground where fish lay down their eggs..

if its safe, hell yeah, bring it. but till then, we shouldnt risks to much. marine wildlife is allreay massivly under presure.

There are fears on wildlife for the electro magnetic fields that wind turbines create though. Also whether the vibrations that they create also do any harm. We don't really know a lot about any of it at the moment.

But to me Tidal does potentially look like the least disruptive and most reliable source of renewable energy. :)
