Rathlin Island was only connected to Northern Ireland's main electricity grid in 2007.
Prior to that it was powered by unreliable wind turbines and old diesel generators.
Now islanders want to use the wind and waves that surround them to create their own green energy.
The ambition is to become completely carbon neutral by the end of the decade, according to Michael Cecil from Rathlin's Development and Community Association.
"The island relies on its ferry service, home heating oil, diesel and petrol for transport on island and gas for cooking," said Mr Cecil.
"All of those things produce carbon dioxide and other gases that pollute the atmosphere. We're keen to remove as much, if not all of that, as possible".
