- 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
- 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
- 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
- Author: Dorian Overhus (Pacific Northwest National Laboratory) Contributors: Andrew Monko and Don Lilly (Global Fiberglass Solutions) Decommissioned wind turbine blades in a Global Fiberglass Solution staging yard in Sweetwater, Texas, U.S. Although wind turbine blades represent a tiny portion of U.S. landfill waste and are among the least environmentally harmful materials entering landfills (… 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
- 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
- The Fundy Ocean Research Center for Energy (FORCE) is Canada’s leading center for research and demonstration of in-stream tidal energy technologies. Located in the Bay of Fundy in the Atlantic province of Nova Scotia, FORCE has been collecting environmental and site characterization data for almost ten years. Based on this experience, FORCE has a role to play in supporting informed, evidence-… Read More
