Europe's largest community-owned wind farm could be built on the Shetland Islands.
The wind farm could create 20% of Scotland's energy needs
Shetland Islands Council has joined forces with Scottish and Southern Energy for the £500m project.
The partners say the 600 megawatt scheme in the islands' central mainland could provide more than 20% of Scotland's energy needs.
A proposal to build Europe's largest onshore wind farm on Lewis is awaiting planning approval by ministers.
