Wind farm fever! Video help needed

[coldraven]

Hi, some consortium is planning to build a wind farm in my area.
They have released some mock-up photos showing the visual impact but seem to have made them blend in with the sky. Whether this is deliberate or not I cannot say but I feel that in reality these turbines will look worse.

So i was thinking of making an animated version, with the blades turning. This might be a better representation of the planed project.
Does anybody know how I could achieve this?

I have had some experience using Sketchup and a little with video editing.
I could maybe shoot some footage of an existing turbine with a blue sky background and chroma-key it out.
But how would I create seven turbines from that and "paste" them over the original JPGs? (Image size 3,004x2,228 6.7MP)

As you may be able to tell. I am not in favour of ruining a beautiful landscape so that someone 200 miles away can watch their 50" plasma TV all day
Any advice would be greatly welcome, thanks

My first thought is Blender. You can create animations, movies ,...

Thanks but I think it would take me a year to learn Blender. That's a great video though
I just found some animated turbines in the Sketchup warehouse. If I could use the JPG as a background and somehow get the scaling right I could make a screencast of the result, maybe.
Other ideas still welcome
