The Department of Energy recently released its Report to Congress on Potential Environmental Effects of Marine and Hydrokinetic Energy Technologies. The Energy Independences and Security Act of 2007 required DOE to prepare the Report in consultation with the National Oceanic and Atmospheric Administration. The Report focuses on the potential effects of marine and hydrokinetic technologies on various aspects of the nation's aquatic environments and finds no conclusive evidence that marine and hydrokinetic technologies will cause significant environmental effects and highlights areas where further information and research is needed.
