The most unreliable source of farm power is wind. This is because wind power depends on the strength and consistency of the wind. If the wind is too weak or too strong, it can't generate enough power. Also, the availability of wind energy is not constant and it can vary from one season to another. In addition, wind turbines are prone to mechanical breakdowns, which can result in extended periods of downtime. As a result, wind power is not always a dependable source of energy for farmers, especially during critical times when power is urgently needed.
