Put the items below in correct sequence for using wind to generate electricity.
1 - a generator converts mechanical energy into electrical energy.
2 - wind turns the wind turbine blade.
3 - a gear box transfers mechanical energy to a generator.
4 - electricity is transferred to the grid.

   2- 3 - 1- 4

Explanation:

Extracting energy from the wind is known as wind energy. Wind energy is are a renewable source of energy.

Energy can be extracted from the wind by following different steps.

1) Wind will turn the wind turbine blade.

2) Then the mechanical energy from the wind turbine blade is transferred to the generator.

3) The generator will convert mechanical energy into electrical energy.

4) the electrical energy produced is then transferred to the grid.

Hence, the sequence of Power generation is  

       2- 3 - 1- 4
