Tidal power?

NC Media Watch: Tidal power?

Why is this the only plant after almost 25 years? We learned that tidal power requires a high tide location, such as the Bay of Fundy on a high volume flow river, such as the Annapolis river. It requires the rivers be dammed so it can capture the tidal flow and the run off. Damming rivers is a environmental concern. When I hear the Democrats talking about the need to develop alternatives to oil and gas energy sources they are always short on details. If tidal power was one of the real green power options it seems we would have more tidal power plants. It has been 24 years since the first one went on line.
