A robust search function allows a user to filter results, for instance, to find all tidal energy projects in the United States, offshore wind projects in Europe, and so on. These images are free for third party use, and attribution should be given to the developer rather than Tethys Engineering.
Pacific Northwest National Laboratory draws on signature capabilities in chemistry, earth sciences, and data analytics to advance scientific discovery and create solutions to the nation's toughest challenges in energy resiliency and national security. Follow us on Facebook, Instagram, LinkedIn and Twitter. Wave development depends on the length of ocean, or “fetch,” over which the wind blows in a constant direction.

Systems typically include a network of underwater power cables that funnel the energy between devices and a main cable that carries the energy to where it's needed on land.
Longer fetches with higher wind velocities will produce larger waves.
Tethys has information on the environmental effects of projects designed to harness ocean energy.
Tidal and wave power devices have been tested on a smaller scale, with one tidal energy project off the coast of Maine that has been connected to the grid. "There is enormous energy capacity within our oceans," said Andrea Copping, an oceanographer at PNNL who heads Tethys. In the United States, offshore wind is set to grow rapidly with multiple projects in the planning phases, including three demonstration projects supported by the Department of Energy announced earlier this month.
The energy of ocean waves is concentrated at the surface and decays rapidly with depth. It seems that Tethys Pnnl content is notably popular in USA.
