A public inquiry is being held into plans for a nine-turbine wind farm on the edge of the Lake District.
West Coast Energy wants to build the 334ft (102m) turbines at Berrier Hill, near the village of Greystoke.
The firm says the farm would produce enough power for about 12,500 homes or 130,000 people.
But opponents, including mountaineer Sir Chris Bonington, claim the development would diminish the "iconic" view to and from Blencathra.
Campaigners have set up the Berrier Wind Farm Objection Group to fight the plans, which they describe as discordant and non-harmonious.
They also claim the turbines would have a negative impact on tourism in the area.
Sam Crosby from West Coast Energy said: "There is always a dichotomy of views over wind farm developments.
"There are many people against, but there's equally as many people for.
"We think it's a great site for wind energy production, and indeed Cumbria's own planning policy identified this area of Berrier Hill as being suitable for up to nine turbines, which of course is what the scheme's for."
The public inquiry, due to last two weeks, is being held at Mungrisdale village hall.
