A green campaigning group says a proposed windfarm in Colby would have paid for itself if it had been built two years ago.
Sustain: Isle of Man took to Facebook after examining Manx Utilities accounts for the past two years.
It says the Earystane site would already have saved £40 million in fuel costs to provide a third of the Island's energy.
And it claims Manx Utilities would be £10 million richer.
The energy provider identified Earystane as a windfarm site last year.
