    In support of the United States' goal to deploy 30 gigawatts of offshore wind energy by 2030, the Department of Energy (DOE) Wind Technologies Office recently announced $15 million for five projects, co-funded by the Bureau of Ocean Energy Management (BOEM), that will provide critical environmental and wildlife data to aid offshore wind development. As part of that effort, the Marine Mammal… Read More

    Offshore wind (OSW) energy is on track to expand rapidly in the U.S. Atlantic, but the potential impacts of siting, construction, and operation on the local wildlife are not well known. There are sizable gaps in knowledge about the behaviors and movements of some species in the surrounding habitats. In support of the Biden Administration’s goal to deploy 30 gigawatts of OSW energy by 2030 (… Read More

    In support of the United States’ goal to deploy 30 gigawatts of offshore wind energy by 2030, the Department of Energy Wind Energy Technologies Office recently announced $13.5 million for four projects that will provide critical environmental and wildlife data to aid offshore wind development. As part of this effort, Coonamessett Farm Foundation (CFF) has just started leading what will be a five… Read More

    In order to responsibly develop marine energy, we need to understand the potential environmental effects on the animals, habitats, and environmental processes. There is still more to learn in order to support the deployment of this low carbon industry in a sustainable manner.   Funded by the U.S. Department of Energy's Water Power Technologies Office, OES-Environmental and Pacific Northwest… Read More
  • Submitted by Tethys Wind Team on
    Tethys is an internationally recognized and trusted broker of information on the environmental effects of wind energy. After twelve years of operation, Tethys hosts over 4,700 documents relevant to wind energy and serves as a collaborative space and dissemination platform for several ongoing U.S. and international research efforts.  To help users discover and navigate the resources available on… Read More

    Canada is witnessing a surge of interest in tidal stream technology development in the Bay of Fundy, but uncertainty around potential impacts on marine life has left the federal regulator, Fisheries and Oceans Canada (DFO), challenged to adequately assess the risk, particularly to fish. This uncertainty challenges the regulatory permitting process; without regulatory approval, developers cannot… Read More
  • Submitted by Luiz Faria (OERA Project Manager) on
    A major project risk in Canada for in-stream tidal energy project developers is the obligation to meet regulatory requirements related to Environmental Effects Monitoring (EEM). The federal regulator (Fisheries and Oceans Canada; DFO) requires each project proponent to demonstrate that their project will cause minimal harm to biological components of the marine ecosystem. Specifically, the… Read More

    The 2020 State of the Science Report was released on 8 June 2020 by Ocean Energy Systems (OES)-Environmental, supported by the  International Energy Agency, and dedicated to examining the environmental effects of marine renewable energy (MRE) development. The 300-page report is the most comprehensive international analysis to date on the issue, based on studies and monitoring from publicly… Read More
  • Submitted by Xavier Guillou (General Directorate for Maritime Affairs and Fisheries, European Commission - DG-MARE), Juan Bald (WESE), Erica Mathers (SEA Wave), Caitlin Long (SEA Wave), and Dorian Overhus (Pacific Northwest National Laboratory) on
    The emerging marine renewable energy (MRE) industry faces many challenges including uncertainty around potential environmental pressures and impacts. This industry is also known as ocean energy, with most early developments being wave and tidal energy generation. MRE stands as one of the main pillars of the European Union (EU) Blue Growth strategy which notes the need for studies, research, and… Read More

    Global renewable energy usage is on a steep upward trajectory, much of which is being driven by wind and solar. However, because of the variability of these sources, renewables are best implemented across as a diverse combination of resources and geography as possible. Therefore, utilizing a new renewable resource that is completely uncorrelated with wind and solar is clearly of benefit. Wave… Read More
