New turbines for the Mighty Mississippi

by Shana on Nov. 05th, 2010

An underwater turbine farm producing enough electricity to power 250,000 homes could one day be installed in the Mississippi. Though the project faces some funding and development challenges, the technology has real promise for a river delta starved of sediments. What if dams could be removed and replaced with freestanding turbines?

Good thinking! It is always important to consider unintended side-effects.

I did a little research and it seems that the jury is still out on the impact of tidal turbines on fish. In science, it's not so much a question of whether or not they are affected (because they are), but to what extent they are affected. In policy, the big question is whether the benefits of the renewable energy outweigh potential costs to little fishy life.

On the flip side, (When animals strike back!) I came across this interesting consideration as well: what about barnacles and mussels? How are we going to find a way to keep them off the turbines?
