Graphene, which is an allotrope of carbon, has attracted the scientific community for its fundamental as well as its technological aspects. It has many promising applications which have revolutionized the semiconductor industry. It is the electronic charge which drives the semiconductor technology; however electrons have two additional degrees of freedom, spin and valley. Spin degrees of freedom has led to the well known subject of spintronics which has made tremendous progress in recent times. However, very limited progress has been made in the study of valley degrees of freedom of electrons, also known as valleytronics. Use of graphene in valleytronics, a revolutionary idea under intensive study, can truly make graphene overtake the markets of semiconductor materials. This paper focuses on those aspects of graphene which can prove to be a pillar of the much anticipated valleytronics field. The use of valley of an electron to increase the speed of the conventional computer by billion times has been discussed. Besides the gauge field (strain) in graphene which somewhat links valleytronics with straintronics is also bought under focus.
