Question

If energy is the ability to cause change, then what evidence is there that energy is produced in the interaction between the wind and the blades of the wind turbine?

Answer 1

according to work energy theorem energy neither be created nor be destroyed it can change its one form to another

the energy carrying by moving fan his wind energy as it rotate the The Blade of fan so wind energy is transferred into mechanical energy which further change its form to electrical energy buy The dynamo which is connected to the fan.

Answer 2

• The blades of the rotating fan transfer wind energy as they rotate, turning it into mechanical energy, which then transforms into electrical energy. the fan's dynamo, which is connected.
• With a force we call lift, wind pulls an airplane's wings upward when it passes over them; wind spins a turbine's blades when it passes over them.
• The turbine gains energy as the wind loses some of its kinetic energy (energy of motion).
• The turbine gains energy as the wind loses some of its kinetic energy (energy of motion).The mechanical energy of the wind is converted into electrical energy by a wind turbine.
• The kinetic energy of a flowing fluid—in this case, air—is transformed into rotary motion by a turbine.
• A wind turbine's blades move or rotate when the wind blows past them. They operate a generator.
