One environmental concern
about wind power is land use. While a single wind turbine does not
use much space, large-scale applications such as utility wind farms
require significant acreage. However, one advantage of wind farms
is that the wind turbines occupy only about 5% of the land, and since
the turbines are high in the air, the bulk of the land is available
for agriculture, grazing, or other uses.
The siting of wind turbines is critical. Key concerns include wind
conditions and velocity as well as surrounding land uses by humans,
wildlife, and other natural resources. During construction, maintaining
a single road of entry can minimize environmental impacts. Installation
of wind turbines is relatively quick and causes little damage to
the land. Many wind farms have multiple uses combining the energy
production with agriculture or grazing.
Still, many critics of wind power consider wind farms an aesthetic
eyesore on the landscape. In a 1991 article in the Town and Country
Planning Journal from the UK, the issue of "educating the visual
consumer" is discussed. This article suggests that members
of the public may be less critical of the visual impacts of windmills
if they truly understood the capabilities of wind mills as an energy
source. The article also provides some suggested separation distance
from various land use categories to mitigate the environmental impacts
of a wind turbine.
