Pe bai Llywodraeth y DU wedi cymryd camau eofn i inswleiddio’n cartrefi a busnesau, cynhyrchu mwy o ynni adnewyddadwy a mwy o wahanol fathau ohono, a defnyddio technoleg glyfar, byddem ar drywydd system ynni lân a sicr.  Pan roedd angen i’r DU gynhyrchu mwy o ynni adnewyddadwy, yr hyn wnaeth y Llywodraeth Geidwadol yn Llundain oedd torri’r cymorthdaliadau fu mor effeithiol i gefnogi technolegau newydd, gosod rhwystrau i ynni gwynt ar y tir pan roedd costau ei gynhyrchu’n cwympo a pheidio â buddsoddi yn y genhedlaeth nesaf o dechnolegau a fyddai wedi sicrhau’r capasiti sylfaenol yr oedd ei angen pan fyddai cynhyrchiant ffurfiau traddodiadol o ynni adnewyddadwy’n isel.
Had the UK Government taken bold action to insulate our homes and businesses, upscale and diversify our renewables, and deploy smart technology, we would be well on our way to a secure, clean energy system.  At a time when the UK needed to be scaling up renewable energy generation the Conservative led government in London cut subsidies that had been so effective at supporting new technologies, put in place new barriers to onshore wind at a time when the cost of generation was falling and failed to invest in new generation technologies that would have provided the baseload capacity needed when generation from traditional forms of renewables is low.
