A yw Llywodraeth Cymru yn monitro'r treial diweddar yn y Swistir sy'n defnyddio paneli solar wedi'u gosod rhwng cledrau rheilffordd i gynhyrchu ynni glân, ac os felly, sut mae'n bwriadu gweithredu'r canfyddiadau?
The Welsh Government always looks with interest to international examples of innovation in renewable energy. Railway infrastructure in Wales (outside of the Core Valley Lines (CVL)) is owned and managed by Network Rail. We remain committed to improving the railways in Wales and continue to work with Transport for Wales and partners such as Network Rail to deliver for passengers.
Whilst we have no plans to install solar panels on the CVL, we are supporting our own green energy innovations such as those pioneered by the SPECIFIC Institute at Swansea University. SPECIFIC seeks to develop innovative solutions so that buildings and infrastructure can become active energy generating units. It has thus far has developed demonstrator units for a classroom, an office, a warehouse and a home.
