      @fionabreen, thanks for asking great questions!

      Tidal energy is energy produced by the tides occurring around our coastlines. When ever there is a tide the sea or river levels rise. This movement of water represents a huge amount of energy that we can capture using under water turbines like this one in Portaferry (Co. Down):

      In Portaferry there is a very narrow passage for the water in and out of the Strangford Lough. When the tide is rising or falling the water rushes through the narrow passage turning the turbine blades and generating electricity. Ire land has great potential for tidal energy as it has strong (high) tides and a suitable coastline (like Portaferry).
