Tidal Energy in the U.S.

In my initial research on tidal power as a feasible source of renewable energy, it is becoming clear that implementation of this technology has to be in areas that will be productive enough to justify the large initial capital investment. I am currently trying to target these sites based on tidal flow rate and proximity to consumers, in addition taking into account potential shipping lanes and environmental impacts.

Pictured above is a tidal power generator installed in Northern Ireland. This particular set-up is capable of producing 1.2 MW, supplying power to about 1000 homes. This design has adjustable blades allowing it to harness both incoming and outgoing tidal energy. A turbine design like the one above is an attractive option for U.S. implementation because of its efficiency in operation. On the flip side, cost as well as depth of the turbine rotors need to be explored before I am fully convinced of this designs practicality in U.S. waters.
