Which is the ultimate source of energy in the wind?

1. Wind arises because air at different temperatures has different pressures. 2. The sun heats the equator more than the poles, driving global air motion. 3. Local breezes also come from solar heating of land vs water. 4. So the ultimate source of wind energy is the sun. 5. Without the sun, the atmosphere would not move. _Source: syllabus Science Ch 14 'Sources of Energy' (byjus.com extract)_
