Cyfrannodd rhanddeiliaid allweddol ar draws sectorau ac ar draws Cymru at ddatblygu’r strategaeth. Tynnwyd ein sylw at nifer o heriau penodol, gan gynnwys: diffyg gwybodaeth a chyngor clir; yr angen i wella sgiliau’r gweithlu i ymateb i’r galw am wasanaethau newydd; yr angen i gynyddu’r gadwyn gyflenwi o opsiynau gwres carbon isel newydd fforddiadwy; yr angen am gymorth ariannol penodol i gefnogi’r achos dros newid; a’r angen i fuddsoddi’n fwy yn ein seilwaith ynni i gefnogi’r symudiad oddi wrth danwydd ffosil.
The strategy has been developed with input from key stakeholders across sectors and across Wales. A number of specific challenges have been identified to us including: a lack of clear information and advice; the need to upskill the workforce to respond to the demand for new services; a need to increase the supply chain of affordable new low carbon heating solutions; a need for targeted financial support to support the case for change; and  a need for more investment in our energy infrastructure to support the transition away from fossil fuels.
