This process involves wind turbines, which convert the wind's energy into mechanical power that. . Why is wind energy generation greater during the night? Hello, I learned that wind energy production is higher during the night, however when searching online every source indicates that wind speeds are higher during the day. Because the earth's surface is made up of different types of land and water, the earth absorbs the sun's heat at different rates. One example of this uneven heating is the daily wind cycle. During the day, air above land heats up. . At night, the winds are reversed because air cools more rapidly over land than it does over water.
