Question

Choose the incorrect statement regarding wind power:

• A. It is expected to harness wind power to maximum and not minimum in open spaces
• B. The source of wind power is the potential energy content of the wind blowing at high altitudes
• C. The rotation of the blades is possible when the wind hits them
• D. Wind energy is used in running the turbine of an electric generator

Answer 1

The correct option is B

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

The explanation for the correct options:

In the case of option ($\mathrm{B}$),

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 protecting the environment.

The explanation for the incorrect options:

In the case of option ($\mathrm{C}$),

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

In the case of option ($\mathrm{D}$),

1. Individual wind turbines will produce up to $100$ kilowatts of power, enough to power a house.
2. Small wind turbines are also used in places like water pumping stations.

In the case of option ($\mathrm{A}$),

1. Wind energy is an environmentally friendly method of generating electricity.
2. Wind power generation setups include blades that are turned by wind due to pressure differences caused by the propellant form of the blades.

Therefore, option B is the correct choice.
