Solution

The correct option is B

The potential energy content of wind blowing at high altitudes is the source of wind power


The explanation for the correct option:

  1. Wind energy is the most mature and recognized renewable energy source.
  2. It generates electricity by harnessing the kinetic energy generated by air currents.
  3. It is a clean and renewable energy source that reduces greenhouse gas emissions while also protecting the environment.
  4. Hence, option B is the incorrect statement that is related to wind power.

Hence, option (B) is correct answer.

The explanation for the incorrect options:

Option A:

  1. Wind energy is an environmentally friendly method of generating electricity.
  2. When the wind blows across the windmill's moving blades, the generator attached to the windmill generates power.
  3. While generating the current in open space, it is expected to produce maximum wind energy.

Option C:

  1. Windmills are used to harness wind energy.
  2. The windmill's blades are rotated by the force of the wind.
  3. Windmills are installed in a specific cluster called wind farms to power a variety of machinery such as water pumps, flour mills, and electric generators.
  4. They produce a significant amount of electricity.

Option D:

  1. Individual wind turbines can produce up to 100kilowatts of power, enough to power a house.
  2. Individual wind turbines will produce up to 100kilowatts of power, enough to power a house.
  3. Small wind turbines are also used in places like water pumping stations.
  4. Kinetic energy is only used in running the turbine of an electric generator.

Hence, options (A), (C), and (D) are correct but since we need to find out the incorrect statement Hence, option (B) will be the correct answer.
