O ran ynni adnewyddadwy'r môr, pwysleisiais sut y mae ein harfordir 1200 cilomedr o hyd, porthladdoedd môr dwfn a’n seilwaith grid hygyrch yn golygu bod Cymru yn berffaith ar gyfer y diwydiant hwnnw. Fodd bynnag, pwysleisiais, hefyd, y sefyllfa annerbyniol lle nad oes gennym y grymoedd angenrheidiol i fanteisio i’r eithaf ar y cyfleoedd y mae’r diwydiant hwn yn eu cynnig i’r economi a chynaladwyedd yng Nghymru. Amlinellais Fframwaith Strategol Ynni’r Môr a’n buddsoddiad o £1m i ddeall effeithiau amgylcheddol ac economaidd-gymdeithasol cael yr ynni ymarferol hwn o’n moroedd. Hefyd, tynnais sylw at ein hymchwil academaidd o safon fyd-eang gan gynnwys y Sefydliad Ymchwil Carbon Isel a phwysleisiais y cyfraniad sylweddol y mae’r sector carbon isel ac ynni adnewyddadwy yn ei wneud eisoes i Gymru a faint y gallai amrediad llanw’r Hafren ychwanegu at y sector hwn.
On marine renewable energy I emphasised how our 1200km of coastline, deep sea ports and accessible grid infrastructure makes Wales ideally suited for this industry.  However I underlined the unacceptable position whereby we do not having the necessary powers to make the most of the opportunities this industry represents for the economy and sustainability in Wales. I outlined our Marine Energy Strategic Framework and our £1m investment to understand the environmental and socio-economic impacts of capturing this practical energy from our seas. I also drew attention to our world class academic research including the Low Carbon Research Institute and highlighted the significant contribution the low carbon and renewable energy sector already makes to Wales and the potential the tidal range of the Severn could add to this sector.
