Wind farms follow the existing land contours. Generally, each tower base is about eight to 10 metres across and spaced from 250 to 800 or more metres apart. Together an entire wind farm including towers, substation, and access roads uses only about five per cent of its allotted land.
Most wind farm projects require at least 60 acres of land per megawatt produced; however, only a very small percentage (about 3%) of this land will be used for the placement of wind turbines and other supporting infrastructure.
On average, it has been reported that each wind turbine currently requires a distance of approximately 300 feet between them. This is equal to an estimated total of 7 complete rotor diameters for the averagely sized wind turbine.
Compared to solar panels, wind turbines release less CO2 to the atmosphere, consume less energy, and produce more energy overall. In fact, one wind turbine can generate the same amount of electricity per kWh as about 48,704 solar panels. Wind turbines are an eyesore. They take up a lot of space.

New research by environmental scientist Paul Behrens and master's student John van Zalk shows how much space is needed for nine specific types of energy. Biomass, hydro and wind, while vital, take up the most space. Natural gas and nuclear take least.
On the cons side, wind turbines can be noisy and unappealing aesthetically, and can sometimes adversely impact the physical environment around them. Similar to solar power, wind power is also intermittent, meaning that turbines are reliant on weather and therefore aren't capable of generating electricity 24/7.
The wind turbine must adhere to the MCS planning standards. The installation must not be sited on safeguarded land. One turbine is considered permitted development and the property must not have an Air Source Heat Pump installed already. Otherwise you need to ask for planning permission.
Wind turbines need a lot of space to work correctly, however, there are discrepancies as to how much space there should be between turbines. The rule-of-thumb for wind farms is 7 rotor diameters between turbines and 150 meters away from obstructions for residental systems.
Wind farms sit lightly on the land, taking up 1% to 2% of the area they are spread across, leaving the rest available for cows, crops or hiking. One wind turbine consumes about 45 to 60 square meters of land at its base.
Each wind turbine creates turbulence in the area behind and around it, so the turbines need to be spaced well apart from each other. The distances in this case are expressed in rotor diameters. The general rule-of-thumb for wind farm spacing is that turbines are about 7 rotor diameters away from each other.
They found a rough average of 4 megawatts per square kilometer (about 10 megawatts per square mile). So a 2-megawatt wind turbine would require a total area of about half a square kilometer (about two-tenths of a square mile).
