English: Can I very much welcome the statement? I'm very pleased that we are again discussing what I consider to be the major issue facing us in Wales. We can either decarbonise or look for a new world to inhabit, because, if we don't, this world will not be able to sustain human life. We are facing a serious climate change emergency, and we've got to address it. I have three questions, and the first one is probably the most important: battery technology. Many of us have visited the Solcer House, and they were using car batteries in order to store electricity. We know that people would like to use electric cars, but they'd like to use electric cars that have batteries that can be charged very easily and very quickly, or where you could have a two-battery system, where you could just swap the battery around in order that you use one, leave the other one at home on charge, and then swap them around. What progress is being made in battery technology? Because, with both cars and houses, unless we get the battery technology right, then we're not going to really get the decarbonisation we want to. The second question is: what is being done to ensure that hydrogen generated for vehicles is produced using renewable energy? Because I see people talking about hydrogen as a renewable - it is - but it takes energy to create the hydrogen in the first place. So, if you're going to use gas-powered generators to generate the electricity to produce the hydrogen, you're actually doing something that is environmentally less friendly. Everybody says, 'It's hydrogen, it must be good' - it's how you get to the hydrogen. And, if you're using electrolysis, you're going to need a lot of electricity in order to split the hydrogen and oxygen, or hydrogen and nitrogen, or hydrogen and whatever elements you wish to have it with. The third point is: more trees. I don't believe you can ever have too many trees, and I think that we ought to have a lot more woodland than we've got now. But have the Welsh Government got any thoughts on trying to create a series of urban forests around urban areas, like the one in Maesteg that Huw Irranca-Davies speaks very highly of? There are lots of other areas, including around eastern Swansea, where we have areas that could be easily covered in trees to the benefit to the environment. Also, we talk about forestry - forestry is a commercial enterprise. We talk about subsidising forestry - forestry for a lot of people is a means of making money. Even Natural Resources Wales, surely, can make money out of forestry.
Welsh: A gaf i groesawu'r datganiad yn fawr iawn? Rwy'n falch iawn ein bod ni'n trafod unwaith eto'r hyn sydd, yn fy marn i, yn fater o bwys sy'n ein hwynebu yng Nghymru. Fe allwn ni naill ai ddatgarboneiddio neu chwilio am fyd newydd i fyw ynddo, oherwydd, os na wnawn ni hynny, ni fydd y byd hwn yn gallu cynnal bywyd dynol. Rydym yn wynebu argyfwng difrifol o ran newid hinsawdd, ac mae'n rhaid inni fynd i'r afael ag ef. Mae gennyf i dri chwestiwn, a'r un cyntaf yw'r pwysicaf, mae'n debyg: technoleg batri. Mae nifer ohonom wedi ymweld â Thŷ Solcer, ac roedden nhw'n defnyddio batris ceir i storio trydan. Gwyddom y byddai pobl yn hoffi defnyddio ceir trydan, ond bydden nhw'n hoffi defnyddio ceir trydan sydd â batris y gellir eu gwefru'n hawdd ac yn gyflym iawn, neu gallech chi gael system dau fatri, gan amnewid y batri i ddefnyddio un, a gadael y llall yn gwefru gartref, a'u cyfnewid nhw wedyn. Pa gynnydd sy'n cael ei wneud o ran technoleg batris? Oherwydd, gyda cheir a thai fel ei gilydd, oni bai ein bod ni'n llwyddiannus o ran technoleg batri, yna ni fyddwn ni'n cael y datgarboneiddio yr ydym yn dymuno ei gael. Yr ail gwestiwn yw: beth sy'n cael ei wneud i sicrhau bod yr hydrogen a gynhyrchir ar gyfer cerbydau yn cael ei gynhyrchu gan ddefnyddio ynni adnewyddadwy? Rwy'n clywed pobl yn sôn am hydrogen fel ynni sy'n adnewyddadwy - ond mae'n cymryd ynni i greu'r hydrogen yn y lle cyntaf. Felly, os ydych chi'n mynd i ddefnyddio gorsafoedd pŵer nwy i gynhyrchu'r trydan ar gyfer cynhyrchu'r hydrogen, rydych chi mewn gwirionedd yn gwneud rhywbeth sy'n llai buddiol i'r amgylchedd. Mae pawb yn dweud, 'Hydrogen yw hwn, mae'n rhaid ei fod yn beth da' - sut y cewch chi'r hydrogen yw'r peth. Ac, os ydych chi'n defnyddio electrolysis, mae angen llawer o drydan arnoch i rannu'r hydrogen a'r ocsigen, neu'r hydrogen a'r nitrogen, neu'r hydrogen a pha elfennau bynnag yr hoffech eu defnyddio. Y trydydd pwynt yw: mwy o goed. Nid wyf i'n credu y gallwch chi byth gael gormod o goed, ac rwyf i o'r farn y dylem ni gael llawer mwy o goetir nag sydd gennym ar hyn o bryd. Ond a yw Llywodraeth Cymru wedi cael unrhyw syniadau ynghylch ceisio creu cyfres o goedwigoedd trefol o amgylch ardaloedd trefol, fel yr un ym Maesteg y mae Huw Irranca-Davies yn canu ei glodydd? Ceir llawer o ardaloedd eraill, gan gynnwys rhai o gwmpas Dwyrain Abertawe, lle mae gennym ardaloedd y gellid yn rhwydd eu gorchuddio â choed er mwyn yr amgylchedd. Hefyd, rydym ni'n siarad am goedwigaeth - menter fasnachol yw coedwigaeth. Rydym ni'n siarad am roi cymhorthdal i goedwigaeth - mae coedwigaeth i lawer o bobl yn golygu ffordd o wneud arian. Mae'n sicr y gall Cyfoeth Naturiol Cymru, hyd yn oed, wneud arian o goedwigaeth.
