“Energy is a need of an hour, save it or there will be no petrol in your car”

Since the beginning of time, energy has pervaded on earth. Man has used this energy and created wonders. Due to the hike in amelioration of scince and technology we have forgot that energy resources are depleting day by day due to certain factors such as overpopulation. We need to conserve energy resources for future use as it takes millions of years for them to revive.

Now, what is energy? Energy is the ability to do any work. . We need energy for assortment of purposes. One cannot live without energy as it has a great relevance in one’s life. We need energy to perform varies functions and also needed by devices.

There are many types of energy. People and other things can run out of energy (e.g. a marathon runner) in which case they can no longer have the ability to do work. In a mechanical situation, if a machine has energy it has the ability to apply a force to another body.

There are many different forms of energy and there are many different places by which energy can be gathered. Forms of energy include: Potential energy, kinetic energy, gravitational l energy, and there are many more. Energy can be gathered in many ways using our natural recourses from the environment, for example: solar energy (from the sun) and hydroelectricity (where electricity is gathered by rushing water)

Potential energy is the energy possessed by a body due to its position, shape, condition or state. Kinetic energy is energy possessed by body due to its motion.

Hydroelectricity is when electricity is generated by rotating coils of wire (rotors) between the poles of a magnet. The rotors are turned by rushing water falling over them. In a hydroelectric plant, water in usually stored in a dam.

As the water falls down and rushes over the vanes connected to the rotors it looses gravitational potential energy and gains kinetic energy. As the metal wire rotates around the magnet it generates electricity which is then sent along power lines to all areas of the city or town. Solar energy is the energy which we get from the sun. Wind energy is the energy which we collect from wind using wind mills to generate electricity.

The energy from natural resources such as sun, wind, water are available on a large scale and should be used.

Conservation of energy also has another meaning and that is to ‘save’ energy. As the natural energy sources become scarcer it is important to learn how to save energy. Nowadays devices such as solar cells, solar cell panel, and solar heater, dryer are available which use solar energy to perform their functions. They should be used as a lot of electricity is saved. These devices have the ability to convert the incoming sun rays into electricity.

It is the time when all people should realize that energy should be saved as it is depleting day by day and we should all try to conserve the energy as: “Energy saved is the Energy produced”.
