Question

State the advantages and limitations in harnessing wind energy.

Answer 1

Wind energy is one of the forms of energy in which we utilise the energy due to the motion of the wind that is kinetic energy to develop mechanical work. The energy of wind is used to move the wind tunnels, which ultimately produces mechanical power, with the help of an electrical generator, we convert this power into the production of electricity.

Complete step by step answer: Let us first discuss the advantages of harnessing wind energy sequentially:
1. Wind can be used again that is renewable; it is available in an unlimited amount.
2. Wind is available for free of cost so the production of energy through wind which makes the maintenance cost cheaper as compared to the other energy sources.
3. There is no change of phase of any material is taking place, so there is no production of pollution involved in this process.
4. There is no conversion of wind into any other form, and there is no effect on the climate.

Let us now discuss the advantages of harnessing wind energy that is the production of electricity using wind energy.
1. This method of energy production is highly dependent on the climatic conditions; therefore, we can install wind energy plants at the places where the blow of wind is more for the year.
2. There should be some minimum speed of the wind so that it can rotate the turbine and this minimum speed depends on the parameters of the turbine.
3. There is a requirement of large fields to install the primary setup of the wind energy plant.
4. The initial cost of installation is high.

Note: Every method of production of energy has some merits and demerits, but wind energy is a renewable source of energy whereas production of energy using fossil fuels will come to an end soon; therefore the production of energy through wind is a more significant alternative for human beings. The advantages of wind energy are more significant than its disadvantages.
