Difference between Wind and Solar energy
Wind energy
- Wind energy is non conventional energy source, which is used is larger scale for production of electric energy in recent time.
- Kinetic energy of air to rotate the blades of windmill, and then this mechanical energy is converted into electric energy using principle of electromagnetic induction.
- Wind mill or wind turbines mainly consists of tower of height ranges from 50 m to 200 m ( base of wind mill) and rotor blades with coil, which converts the wind energy in electrical energy.
- Construction of Windmill is expensive and do not produce electricity in large scale, hence farm of windmills is constructed and electric energy produced by each tower is collected so as to use for commercial purpose.
- It is pollution free, hence environment friendly.
- Germany is top at the names of countries which produces electric energy from windmill, whereas India ranks 5th in the list.
Solar energy
- Solar energy is non conventional source of energy.
- Energy radiated from sun i.e. light energy emitted by sun is used to produce electric energy or heat energy.
- Light energy emitted by sun is used to produce electric energy using solar panels made up of semiconducting devices.
- Light energy also used to produce heat energy with instruments like solar cooker, solar heater.
- The only drawback of this energy is that it is not available throughout all seasons for 24 hrs.
- Its pollution free, and almost free of cost except its initial installation price, which makes solar energy as eco friendly source of energy.
