Windmills have been used since the middle ages, wind farms are just an extension of that technology.
Because wind levels are higher there than most other parts of the UK.
As of 11 January 2009, there are 269 operational wind farms in the UK, with 2,764 turbines and 4,070 MW of installed capacity
Yes they do ! Since the UK is an island group, with an undulating landscape, there are many suitable places for wind farms. Many coastal areas have them, as to high, exposed places.
Wind farms were invented in Persia.
wind farms are built to produce electricity through wind power
there are advantages of building windfarms and there are disadvantages of building them. I have no time to improve this answer.
wind farms provide electricity. Wind farms cost more to maintain and construct than the energy that they provide. In addition they very inefficient because they only work when there is wind.
There are many wind farms in the world. Every country has its own set of wind farms. There is no such list for all the wind farms in the world. However you can go through the list of Top 10 Biggest Wind Farms in the world in the given link. http://www.power-technology.com/features/feature-biggest-wind-farms-in-the-world-texas/
