Question

The ultimate source of energy that drives wind power is __________.

Answer 1

The ultimate source of energy for wind power is the sun, which creates atmospheric conditions leading to wind. Wind turbines convert this wind energy into electricity. All renewable energy, including wind and hydropower, originates either from the sun, Earth's heat, or gravitational forces.

Step-by-step explanation:

The ultimate source of energy that drives wind power is the sun. The sun's energy generates heat that drives weather patterns and atmospheric pressure differences, leading to wind. This wind energy is harnessed using wind turbines, such as those found in wind farms, to generate electricity without emitting pollutants or requiring water for cooling. The technology for capturing wind energy is not new, as it's been used for centuries in sailing, milling, and water pumping, but has become increasingly sophisticated to efficiently convert wind energy into electrical power through the use of turbines and generators.

It is important to note that all forms of renewable energy, including wind and hydropower, ultimately derive from the sun, the heat of the Earth's crust, or the gravitational pull of the moon and sun. Solar energy, in particular, is responsible for the atmospheric conditions that give rise to wind and the water cycle that powers hydropower.

Answer 2

So we want to know what is the ultimate source of energy that drives wind power. The Sun is the ultimate source of energy because it heats up the Earth's atmosphere. Since the hotter air has lesser density, it starts to rise up. As it rises up it starts to cool. And as it gets cooler, it's density again rises and it gets heavier and starts to fall down. This is what we notice as wind. So the correct answer is: the Sun.
