Riverkeeper, an environmental organization, is keeping an eye on underwater turbines. Some mechanisms suck in and harm fish, damaging the local ecosystem and biodiversity, says Riverkeeper General Counsel Robert Goldstein. His group is waiting to see results of a study by Verdant. “If it doesn’t harm the fish, we not only approve,” but hope to see more such non-carbon-generating power sources, Goldstein said.
