Which of the following sources of power supply to the farm is most unreliable?
Answer Details
The most unreliable source of power supply to the farm among the options listed is wind. This is because wind energy is highly dependent on weather conditions, and its supply can vary greatly from day to day or even hour to hour. Wind turbines can only generate electricity when there is sufficient wind speed, and if the wind is too strong, the turbines have to be shut down to avoid damage. In addition, wind power generation requires large initial investments and can be affected by issues such as noise pollution and bird mortality. On the other hand, electricity, animal, and machine power can be more reliable as they are not as affected by weather conditions and can be controlled more easily.
