Band 7 IELTS Essay Sample
A consistent increase in the popularity of solar energy as a means of providing household energy has been noticed in many countries around the world.
Many factors contribute to this gradual increase in the acceptance and acknowledgment of Solar Energy. The need to meet the ever growing requirements of energy supply is the main motivation behind pursuing the development of an alternative energy generation system. Another reason is the non-existence of any harmful by products of the solar power generation system, unlike all other types of energy generation systems.
There are several advantages of Solar Energy. Unlike other energy sources like coal and petroleum the source of solar energy the sunlight is non-perishable .The absence of any harmful impact on the environment and the ability to function in perfect harmony with the ecosystem makes it an ideal energy generation system. In addition to this the abundant supply of sunlight and the improved technology to tap into this energy source has immensely helped in the increase of its popularity.
However there are few problems associated with solar energy. The limited although improved technology dampens the drive to use it as a power source. Moreover there are various other factors such as the lack of a support system for repairs, replacement of malfunctioning devices in the domestic solar generation systems which are proving to be a major hindrance. Another issue is that the availability of sunlight is subject to many factors and there are many countries worldwide which do not receive any sunlight during certain parts of the year. Replying on such dynamic power source might handicap the users of the system in more than one way.
In conclusion I would like to emphasize on the need to overcome the technological limitations marring the growth of the solar generation system into a reliable energy supply system used throughout the world.
