English: I thank Siân Gwenllian for those questions. In terms of the question on new builds or the older estate, there is a difference, of course, in the approach to those things. To be clear, the policy I'm talking about today also includes broad-ranging renewal work in a broad range of schools, so it isn't restricted in that way, but the general point that the Member makes is a fair one. In terms of timetabling the retrofitting work, the plan that was announced last week by the First Minister and the Minister for Climate Change talks about developing a strategic plan to decarbonise buildings by the end of 2023, that all public buildings have a low-carbon energy stream and, if they can, create their own energy as well. So, the timetable is longer, for the reason that the Member recognises in the question, because a lot of the estate is older. So, we need to map that work out before we can proceed with it, but it is an important element of the journey that we're on in terms of being a net-zero nation. In terms of workforce skills, I'll refer the Member to what the Minister for Economy said, but it's certainly part of the further education agenda here in Wales. As well as this statement, this week, the Bill is being introduced for post-16 reforms, and one of the opportunities and the challenges that that's going to allow us to tackle more effectively is some of the new needs in our economy, so that we can respond in a much more flexible way to the demand for new skills, as it were, in the economy. So, that contributes towards that. In terms of the challenge fund, the reason for restricting it in the first phase to primary schools is that the projects are easier to deliver and so that we learn lessons for more broad-ranging projects. Last week, I was in Nottage Primary School in Sarah Murphy's constituency to meet the children there, who had contributed to the design and construction of part of their playground. So, it's a small example of that - we're talking about a more ambitious agenda here - but it was very clear, in terms of the question that the Member asked, that the process of learning those skills and tackling the buildings showed great talent and creativity among the pupils, who were very innovative. So, the intention here is to have an initial scheme that focuses on primary schools in order to show the broader concept and to learn from that so that, hopefully, we can build on that.
Welsh: Diolch i Siân Gwenllian am y cwestiynau hynny. O ran y cwestiwn ynglŷn ag adeiladau newydd sbon neu'r ystad hynaf, mae gwahaniaeth, wrth gwrs, yn yr approach tuag at y ddau. Jest i fod yn glir, mae'r polisi rwy'n ei ddatgan heddiw hefyd yn cynnwys adnewyddiadau eang mewn ysgolion o unrhyw oedran fel petai, felly dyw e ddim yn gyfyngedig cweit yn y ffordd honno, ond mae'r pwynt cyffredinol mae'r Aelod yn ei wneud, wrth gwrs, yn bwynt teg. O ran amserlenni'r gwaith retrofit ac ati, mae'r cynllun a gyhoeddwyd wythnos diwethaf gan y Prif Weinidog a'r Gweinidog Newid Hinsawdd yn sôn am ddatblygu cynllun strategol i ddatgarboneiddio adeiladau erbyn diwedd 2023, bod pob adeilad cyhoeddus â ffynhonnell wres carbon isel erbyn 2030 ac, os gallan nhw, yn creu eu hynni eu hunain hefyd. Felly, mae'r amserlen yn un hwy, ond am y rheswm mae'r Aelod efallai'n cydnabod yn y cwestiwn, sef bod lot mawr o'r ystad yn hŷn. Felly, mae angen mapio'r gwaith cyn ein bod ni'n gallu mynd ati i wneud hynny, ond mae'n elfen bwysig, wrth gwrs, o'r siwrnai rŷn ni arni tuag at fod yn genedl sero-net. O ran sgiliau'r gweithlu, fe wnaf i gyfeirio'r Aelod at yr hyn wnaeth Gweinidog yr Economi ei ddweud, ond hefyd mae'n sicr yn rhan o'r agenda addysg bellach yma yng Nghymru. Ynghyd â'r datganiad hwn, yr wythnos hon, mae'r Bil yn cael ei gyflwyno ar gyfer diwygiadau ôl-16, ac un o'r cyfleoedd a'r sialensau mae hynny'n mynd i ganiatáu i fynd i'r afael ag e'n fwy effeithiol yw rhai o'r anghenion newydd yma yn ein heconomi ni, fel ein bod ni'n gallu ymateb mewn ffordd lot mwy hyblyg i'r galw am sgiliau newydd, fel petai, yn yr economi. Felly, mae hynny'n cyfrannu tuag at hynny. O ran y gronfa her, y rheswm am ei chyfyngu yn y cam cyntaf i ysgolion cynradd yw bod y prosiectau efallai'n haws eu delifro a bod hynny'n dysgu gwersi inni ar gyfer prosiectau ehangach na hynny. Fe fues i'r wythnos diwethaf yn ysgol gynradd Nottage yn etholaeth Sarah Murphy i gwrdd â phlant fanna a oedd wedi cyfrannu at ddylunio ac adeiladu rhan o'u maes chwarae. Mae'n enghraifft fach - rŷn ni'n sôn am rywbeth lot fwy uchelgeisiol fan hyn - ond roedd e'n gwbl glir, o ran y cwestiwn olaf a wnaeth yr Aelod ddweud, fod y broses o ddysgu'r sgiliau a mynd i'r afael â'r adeiladu wedi dangos talentau a chreadigrwydd ymhlith y disgyblion, a oedd yn arloesol iawn. Felly, y bwriad yma yw cynllun cychwynnol sydd â ffocws ar ysgolion cynradd er mwyn dangos y cysyniad ehangach a dysgu o hynny fel ein bod ni'n gallu, gobethio, ehangu ar hynny.
