Thought Provoking Photo

Here is an interesting photograph which shows the downstream effect of windfarm on the atmosphere. Saw this from Sustainable Energy blog. What immediately comes to mind are the following:
  • What is the climate cooling affect of these artificially created white clouds (because more sun energy presumably will be reflected back into space). Is this modelled by the climate change models?
  • Extrapolating to the limit for when the planet is carpeted with these devices, what will be the actual efficiency we are left with?
