    Only for the better. I cant see any possibility of adversely affecting the earths weather. Windmills are relatively low to the ground a "windmill farm" offers no more wind resistance than trees of the same size, I dont think a small forrest can have that much affect on weather through wind resistance, in fact I dont think it would have any affect at all.

    In theory, If we can eliminate the use of all fossel fuels, then yes the weather can be affected, but there would be far more variables at play than simply having a lot of wind mills & that was what was causing the change. It is more about what you are taking away (polution) than what you are adding (windmills).

    Hypothetically it would be something like this:
    1) Put in enough windmills to power the world, or at least eliminate power plants that burn fossel fuels. This would reduce pollution.
    2) Make all cars eletric powered, they charge at your house, thus they get their power from wind power. Eliminate any car that burns gas, another major reduction in pollution.
    3) Industry, most companies producing anything get their power from steam. Steam use means a big, industrial, fuel burning, boiler. There is technology to boil the water with electric power rather than fuel, but the electricity is too expensive to be viable for the company to use, So you have to make electricity cheap as well, obviously more wind mills.
    4) Wait 20 - 30 years greenhouse gasses reduce, the hole in the ozone layer shrinks, global warming slows, acid rain reduces & Voila, a change in the earths weather! ...for the better!

    Incidentally, all of this is debatable, there are some who believe global warming is a natural progression, the hole in the ozone layer was always there and the effect of burning fossel fuels is minimal, however this is not the common belief in the scientific community.
