San Francisco launches a study of tidal power.
There is enormous potential here but tidal power is in the earliest concept stages, perhaps like wind twenty years ago. And doubtlessly there will be some of the same problems like siting and minimizing wildlife impacts. However, if the concept is proved it could become viable quickly especially since it has one huge advantage over wind - the tides are always 'blowing' so the power is available on demand, "dispatchable" in utility-speak.
Updated: More here on SF's energy plan. The target is 51% green power in 10 years.
Update: More on the tidal project on Quest radio
Update 2: The Christian Science Monitor carries an article on the topic
