Protests have been staged against three controversial wind farm applications as they were discussed by councillors in Powys.
The applications for Llanbrynmair, Llaithdu and Llandinam will be decided by the UK government because they are set to generate over 50 megawatts.
The council cabinet decided to formally oppose all three planning applications.
RenewableUK Cymru said the decision was a blow to many businesses that stood to benefit from the developments.
