The table does not support the premise that there are tidal barrages that are to be installed It does exactly what the title says which is list places where Tidal power schemes being considered The title allows for the inclusion of any places of interest where tidal power schemes have been proposed not just ones that are about to be built   I didnt create the table and I dont know where Secure Bay is However  seconds of searching for the string Secure Bay Australia gave the following result  As a self proclaimed leading world expert you should be able to find these things   The energy number in the Severn UK row agrees with the number in the Severn barrage page which agrees with the referenced UK Government report Note that the table shows Mean tidal range rather than Peak tidal range which may be the source of differences in the tidal range numbers Severn estuary is m peak   The table is a useful source of high tidalrange locations where schemes have been proposed It is a shame that there are few references but the table has existed since before Wikipedia decided to push references harder Given your history here I hope you understand that the fact that you dont know where some of these places are is not enough to see them deleted   Instead of seeking to suppress information about forms of tidal power that you dont like why dont you spend more time adding referenced and NPOV information about forms of tidal power that you do like Thanks
