Welcome to the Marine Energy Environmental Toolkit – a comprehensive compilation of existing environmental, spatial, regulatory, and scientific data relevant to the permitting and development of wave, tidal, river, and ocean current energy-harvesting technologies.

The Toolkit was developed in collaboration with regulators and developers to create a useful and lasting permitting and licensing resource. The Toolkit was funded by the U.S. Department of Energy (DOE) and was built to complement other DOE efforts, such as the Portal and Repository for Information on Marine Renewable Energy (PRIMRE). Information provided is primarly from Tethys Knowledge Base and the FERC eLibrary.

Marine Energy is the harnessing of water’s kinetic energy to generate electricity. It encompasses wave, tidal, and river and ocean current power.
