Electricity is vital in our daily lives as to a large extent most of us are dependent on electricity for a quite a number of daily jobs. It is the source that lights up the appliances, the air conditioners, the fan and it is also very important for a lot of industrial processes. Electricity is generated through a number of sources; some are renewable sources while some are non renewable ones. Solar energy is on a rise these days mainly because of the fall in the solar power prices, increasing demand for renewable energy and also because of the need to save the environment.
India is undoubtedly a nation where there is maximum production of power from the renewable sources of energy. Just like solar energy, wind is also a source of renewable energy and India is considered to be the fourth largest wind energy producer in the world. Wind energy is growing at a fast speed in the world mainly because of all the various benefits that it offers. The wind energy is converted by the wind turbines, which are of two types the horizontal and the vertical axis wind turbines. In order to create electricity from wind, the shaft of the wind turbine has to be connected with a generator. This is the basic requirement for creating wind energy.
Advantages of wind energy
- It is cost effective and land based, which makes it the lowest priced source of energy.
- Wind energy helps in creating jobs for the unemployed, as the installation, maintenance and manufacturing of wind energy requires a lot of work force.
- It is a clean fuel, which means it doesn’t pollute the environment and it has an abundant supply which is inexhaustible.
Except for these renewable sources of energy, there is one such non-renewable source of energy also that is used for energy supply and that is coal which is quite popular and widely used by the people of India.
Non renewable resource (coal)
Indians are not only dependent on solar and wind energy but also on the coal for producing energy, coal is the centre of all the resources and without it the future of our country would be in Dark. The reason for this is that it is affordable power as we as it is found in abundant in our country. In order to get electricity from coal there is a long process that needs to be followed:
- Coal is milled into powder form as it can be burnt quickly.
- Then the powdered form is blow into a chamber of the boiler where the coal is burnt at a high temperature.
- After this the hot gas and energy produced by it, is converted into steam.
- Then the converted steam is pushed through the turbine shaft which at the end produces electrify.
So whether one uses renewable or non renewable, the main motive should be to produce electricity as there are still a lot of houses and villages where there is still no electricity.
