A wind farm (wind park) is a collection of wind turbines in the same location used to produce
electricity Wind farms come in different sizes A wind farm can include a small number of turbines or several hundred wind turbines covering a huge area Wind farms can be either on the land or in the sea
Wind farms have a lower environmental effect than many other sources of electricity because they do not require fuel For that reason, people often consider wind farms a good source of green energy However, people often criticize wind farms because they affect the landscape Normally, wind farms need more land to build than other power stations Wind farms are often in wild and rural areas, and people living in those areas believe the construction of a wind farm causes habitat loss and affects tourism
A wind farm has 6) sizes Engineers can build a wind farm offshore or on 7) A wind farm does not have many 8) impacts Wild and 9) areas are suitable for building wind parks However, people are not excited about that because they think it causes habitat loss and affects the landscape and 10)
