Ar raglen Dros Frecwast fore Mercher, dywedodd Dr Carol Bell – sy’n arbenigwr ar y diwydiant ynni – nad yw’r cynnydd diweddaraf yn syndod yn sgil y gwrthdaro yn Iran.
“Fi’n credu bydd prisiau trydan pobl yn fflat, ond bydd prisiau nwy yn mynd lan ryw 8%, felly mae dod â’r TAW i ffwrdd o bris trydan yn mynd i wneud gwahaniaeth i bobl sy’n dibynnu ar drydan,” meddai.
“Yr hyn mae’r llywodraeth eisiau ‘neud yn y pen draw, a’r hyn fydd rhaid iddyn nhw ei wneud yn y pendraw, yw defnyddio llai o nwy.
“Mae’r cynnydd mewn ynni adnewyddol ym Mhrydain yn beth pwysig, ond mae hynny yn dod efo cost – ac mae gweddill y pris yn adlewyrchu’r gost o symud y system o losgi nwy i ddyfodol mwy glân sy’n llai dibynnol ar y farchnad ryngwladol.”
