A novel flux methodology approach to modelling the energy available in tidal streams is demonstrated, and compared with an earlier assessment using the farm methodology. Using a combination of existing public domain pictorial data and the graphical capabilities of a readily available BASIC programme it is shown that a realistic quantification of the overall energy flux within a tidal stream can be found, relatively quickly and without the need to employ complex numerical models. The method is applied to the Channel Islands and compared to an earlier study, which used the farm methodology. The results indicate that whilst the resource may not be as large as previous reports suggest, current understanding of tidal stream energy flux is now on firmer ground.
