This site-wide search returns results for all documents, events, metadata, and stories in Tethys, prioritizing the best matches. Partial word matches are returned (e.g. "environment" finds "environmental"), but every entered term must be found. If you don't find any results, try reducing the number of words entered or removing special characters. Filters to the right can help narrow your search. Tethys now features an integrated search with other marine renewable energy databases in PRIMRE - click the buttons below "Showing Results for" to search other integrated databases.

Early deployments of wave and tidal energy projects are providing information on environmental effects of the devices, moorings, and power cables; these data will help inform later deployments and guide regulatory decisions as the industry moves towards the commercial scale. However, there is still considerable uncertainty about many potential interactions of devices and systems with the…
An overview of the United States' Powering the Blue Economy (PBE) initiative. Specifically, how marine renewable energy's history and feasibility has influenced this new funding direction for the Department of Energy's Water Power Technologies Office. Marine energy has a unique opportunity to power other maritime industries as well as provide resilience for remote coastal communities. One…
- … This presentation, presented by Andrea Copping, discusses the Annex IV process in depth. Firstly, the Annex IV is a searchable database …
This presentation mainly focuses on the importance of environmental effects for accelerating marine energy development. It provides information regarding the drivers of marine energy development, a concept in sharing information and analyses internationally, Metadata forms, workshops, and moving forward.
The marine renewable energy (MRE) industry is young—most technology development and testing for tidal and wave devices has taken place over the past 10–15 years. As wave and tidal devices continue to be deployed for demonstration, testing, and pilot projects, and the earliest commercial arrays are being developed, regulators around the world are requiring that a significant amount of data be…

This presentation is an explanation of the Ocean Energy Systems Implementing Agreement. This agreement is a framework that exists under the International Energy Agency. However, the IEA is not directly involved, but they do provide the foundation to facilitate international cooperation. The agreement was introduced in 2001 by 3 countries and has now grown to 18. The mission is to, by 2020,…
Potential environmental effects of offshore wind (OSW) energy development are not well understood, and yet regulatory agencies are required to make decisions in spite of substantial uncertainty about environmental impacts and their long-term consequences. An understanding of risks associated with interactions between OSW installations and avian and aquatic receptors, including animals,…
With only a few wave and tidal devices in the water and no long-term post-installation data sets available, there continue to be uncertainties around risks to marine animals and habitats from the deployment and operation of marine renewable energy (MRE) systems [1], [2]. Based on these uncertainties and lack of familiarity with MRE devices, regulators and stakeholders continue to perceive a…
This complete reference to marine renewable energy covers aspects of resource characterization and physical effects of harvesting the ocean’s vast and powerful resources—from wave and tidal stream to ocean current energy. Experts in each of these areas contribute their insights to provide a cohesive overview of the marine renewable energy spectrum based on theoretical, numerical modeling, and…
This report outlines a coordinated action plan aimed at reducing the scientific uncertainty associated with collision risk of marine animals and tidal turbines. This plan includes steps to take toward resolving the challenging issue of decreasing scientific uncertainty, but is unlikely to completely solve the problem. The content of this report was derived from the involvement of experts…
In response to the Energy Independence and Security Act (EISA) of 2007, the U.S. Department of Energy, Energy Efficiency and Renewable Energy (EERE) Waterpower Program Office developed a program on marine and hydrokinetic (MHK) energy development. During fiscal year 2009 (FY09) the EERE Waterpower Program provided support to Pacific Northwest National Laboratory (PNNL) to enable staff to…
The OES-Environmental 2020 State of the Science Report: Environmental Effects of Marine Renewable Energy Development Around the World complements and serves as an update to the 2013 Final Report…
As tidal turbine deployments continue at test sites and in commercial areas, the potential risk for injury or death of marine mammals from colliding with rotating turbine blades continues to confound efficient consenting (permitting) of devices. Direct observation of collisions is technically very challenging and costly. Estimates of collision risk to date have been derived from complex…
Floating offshore wind farms have been proposed in the deep waters off the U.S. west coast and Hawaii to provide renewable energy to coastal populations.Anchoring floating wind platforms to the seabed requires multiple mooring lines that pass through the water column from platforms at the surface to the sea floor. Electrical cables also will be draped in the water column between wind platforms…
Ocean Thermal Energy Conversion (OTEC) uses the temperature differential between warm surface ocean water and deep cold ocean water to generate power through a heat exchanger process. Deep ocean water is generally between 2o and 4oC; the temperature differential of 20oC needed for OTEC is found only in tropical waters. In the United States,…
More details of this workshop are available here.
The purpose of Annex IV is to provide a collaborative project under the International Energy Agency’s (IEA) Ocean Energy Systems Implementing Agreement (OES-IA) that will identify ongoing research and bring together data on the environmental effects of marine and…
The marine environment has the capacity to provide large amounts of clean, renewable energy through its waves and tides. As marine renewable energy (MRE) devices are being tested, concerns regarding the potential effects of MRE devices on marine organisms, habitats, and ecosystem processes continue to slow permitting. To address these concerns, and further advance the industry, an…
