Your raise an excellent question, Rebecca. If the captured energy is a small fraction of that available, side effects should be small. When we examined hydrokinetic energy captured by placing turbines in rivers, we found that large arrays of turbines could potentially affect water quality, sedimentation, habitats, biota and navigability of waterways*. Every situation should be examined for the tradeoffs.

This paper goes somewhere I would like to see taken further. We engineers, above all others, need to be more thoughtful about consequences than we tend to be. When we extract "free" energy from somewhere, we need to be better about asking the question, "What is NOT going to happen or NOT going to get done as a consequence of the absence of the "free" energy we're extracting." This paper starts in that direction a little bit by considering what happens when. . . . That needs to be a careful consideration as we look at tidal, wave, and deep sea energy capture. All that energy has been doing something for millennia. What?
