The community ballot over Cove Community Wind Farm has shown a big majority in favour of the project.
Promising to bring in more than £300,000 a year for local causes, it would be the biggest of its kind in the UK.
Today (Wednesday) the result of a ballot which saw voting slips distributed through doors and at a public were revealed.
Murdo MacDonald, convener of Rosneath Peninsula West Community Development Trust, which is behind the project, said from a total adult population of 1268, there were 617 returns, or 49% of the electorate.
Of these, 508 voted yes, representing 82% of those that voted, and 109 voted no.
A previous similar poll before the feasibility study was launched said 94% were in favour.
“This is a terrific result and reflects great credit on all concerned,” said Mr MacDonald.
“We now move on to the next step which is applying for planning permission. We will ask for your help again to support that application.
“Many thanks and congratulations to all who have helped us thus far.”
The trust board have visited neighbouring communities including Ardentinny, Blairmore, Kilmun, Rosneath, Clynder, Rhu, and Shandon in recent weeks to outline the plans.
Meetings have also been arranged in Helensburgh and Garelochhead.
