A windfarm extension that began a row between Pembrokeshire Coast National Park and Friends of the Earth Cymru will go ahead.
The turbines will be about nine miles (14.5km) from Tenby
Six new turbines can be added to the site at Pendine in Carmarthenshire after councillors backed them.
The park authority said the structures, about nine miles (14.5km) from Tenby, would detract from the scenery.
But Friends of the Earth Cymru said the objection was "bizarre" as the turbines were outside the park.
Carmarthenshire's planning officers told the committee the extension at Parc Cynog Farm would make a "significant contribution" to the generation of renewable energy.
The five turbines already in place were granted on appeal six years ago.
The park authority opposed the extension saying it had a duty to "preserve and enhance the natural beauty of the park".
The Council for the Protection of Rural Wales and the Countryside Council for Wales also objected.
But Friends of the Earth spokesman Gordon James said they would produce enough electricity to power around 6,000 homes.
"Wind power is one of the cleanest forms of energy available - the fuel is free, abundant and inexhaustible, and no carbon dioxide or waste is produced," he said.
"We find it bizarre that an authority that is meant to protect the natural environment should object to turbines that will help to reduce the impacts of climate change."
