A wind turbine that cost the Welsh government £48,000 to buy has been generating an average of just £5 worth of electricity per month.
The turbine was put its Aberystwyth office, rated excellent for sustainability, in 2009.
The Welsh government said the turbine had mechanical problems.
But before it was installed, the turbine makers warned Welsh government contractors it would not be exposed to enough wind where it was positioned.
