    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

    A small nonprofit based in Portland, Ore. is helping to place the Pacific Region of the United States – comprised of California, Oregon, Washington, Alaska, and Hawaii – on the map as a vibrant destination for ocean renewable energy research and development. Available offshore wind, wave, and tidal resources offer significant opportunity for states in the Pacific Region to meet their renewable… Read More

    The number of fatal bird collisions at wind turbines is rarely studied in relation to the number of birds observed crossing an area. The reason might be that the acquisition of such data is time consuming, costly, and not trivial. The analysis and interpretation of radar data is especially difficult. Furthermore, there are a variety of radar systems and not all systems are technically suitable to… Read More

    Jim Strittholt, Conservation Biology Institute (US) In order to effectively combat climate change, rapid transition to renewable energy is essential and new economic opportunities are rapidly emerging. The recent progress towards renewable energy is encouraging, but care must be taken to avoid unintended negative consequences on wildlife and existing human uses whether these new developments are… Read More

    As the marine renewable energy (MRE) industry advances and devices are deployed, there is a need to understand potential environmental effect of introducing structures to marine waters and potentially attracting marine organisms. These structures may act as artificial reefs, underwater human-made structures that function similar to a natural reef, and can include oil and gas platforms, sunken… Read More

    At the University of Rhode Island in the United States, a study of electromagnetic field (EMF) impacts on elasmobranchs and lobsters is currently being conducted. The contract is led by the Bureau of Ocean Energy Management and the study aims to assess impacts of direct current (DC) cables on marine organisms. The study was prompted by the potential for the “Atlantic Wind Connection” venture, a… Read More

    The Province of Nova Scotia has set an ambitious renewable energy production target of 40% by 2020.  One of the mechanisms to achieve this goal, initiated by the Province, was the creation of the Fundy Ocean Research Centre for Energy (FORCE) tidal turbine test facility in the Minas Passage, Bay of Fundy. The first of two commercial-scale tidal turbines (16 m diameter Open Hydro turbines)… Read More

    Adaptive management (AM) is a learning-based management approach that is used to reduce scientific uncertainty. AM has been identified as a tool to advance the wind energy industry, although its application in practice has been limited.  AM has primarily been actively implemented in the United States, while other nations have applied some of the principles of AM. Many wind energy projects use the… Read More

    One of the key features of renewable energy generation is its benefit to the environment through developing low carbon power sources, so it’s important to develop new types of renewable energy in environmentally responsible ways. Collecting and analyzing environmental data necessary for marine energy projects is difficult – the areas of interest are highly energetic, with (typically) little… Read More
