- Water Pumping: Windmills are commonly employed to pump water from underground sources, such as boreholes and wells. This pumped water is then used for agricultural activities such as irrigation and livestock watering.
- Power Generation: Windmills can also be used to generate electricity. Some farms have installed wind turbines to harness wind energy and produce electricity for their operations.
- Grain Milling: In the past, windmills were utilised for grinding grains and producing flour. Although modern technology has largely replaced this usage, some heritage farms still maintain and operate these windmills for educational or historical purposes.
- Ventilation and Cooling: Windmills can aid in providing ventilation and cooling for farm structures, such as barns and sheds, by naturally circulating air.
- Decorative and Heritage Value: Windmills often hold significant cultural and heritage value. Many farms preserve these iconic structures as historical attractions, adding a touch of nostalgia and charm to the farm environment.
The prevalence of windmills on South African farms varies depending on the region and the specific farming practices. However, they remain an important and iconic part of the country's agricultural heritage.
