What is a common challenge associated with wind energy?

Wind energy generation relies on the presence of wind, making it imperative that wind blows for turbines to generate electricity. When wind speeds are insufficient, energy production decreases or halts completely, leading to reliability issues compared to other energy sources. This intermittent nature is a fundamental characteristic of wind energy, as there are times when there may be little to no wind, particularly during calm weather conditions or in specific geographic locations. Consequently, this variability presents a challenge for integrating wind energy into the overall energy grid, as consistent power supply is essential for meeting demand.
