The Welsh Government is under fire over a wind turbine that it built at its offices in Aberystwyth
A Freedom of Information request has revealed that the turbine cost £48,000, but it generates £5 of electricity a month.
The revelation came as the First Minister Carwyn Jones was officially opening a new super energy efficient house in west Wales.
The building, at Cilgerran in Pembrokeshire, is said to be so eco friendly that it will never have a gas or electricity bill.
