Mae targed hefyd i gynhyrchu 5.5 GigaWatt o ynni adnewyddadwy drwy bympiau gwres erbyn 2035 ond mae hyn yn amodol ar dderbyn cymorth ychwanegol gan Lywodraeth y DU a gostyngiadau yng nghost technoleg.
There is also a target for 5.5 GigaWatt of renewable energy capacity to be produced by heat pumps by 2035 but this is subject to scaled up support from the UK Government and reductions in the cost of technology.
