More study needed of wave, tidal energy impacts 

This isn’t a news item per se, but a new Canadian Science Advisory Report details what needs to be studied about wave and tidal energy impacts. This is interesting because Alaska has such potential in this area with an estimated 50 percent of the country’s potential wave power and 90 percent of its potential river current and tidal power. There are also ongoing efforts to look at tapping in stream turbine power in Alaska, and installing a turbine in Cook Inlet.

The report gives a good summary of the areas that need to be studied as this technology advances from possible impacts of noise and vibrations on marine life to any impacts on water quality.

Here’s a short summary of the need for the report: Canada’s vast and highly energetic Atlantic, Pacific and Arctic coastal waters make ocean renewable energy, particularly tidal in-stream energy conversion (TISEC) and wave energy conversion (WEC), technologies an attractive option to help meet the country’s future energy needs. However, due to the novelty and diversity of these technologies, there is still a great deal of uncertainty surrounding the feasibility and potential environmental impacts associated with their deployment and operation. In support of commercial development of the industry, a review of scientific knowledge is required for the development of policy and regulations consistent with Canada’s conservation and sustainability priorities.
