Technological developments and advancements are making a significant effect on our daily lives, be it in the industry, in arts, in science etc., However, the knowledge and skill dedicated by the human society towards these lifestyle improvements has indirectly contributed to an ecological threat that the world is facing today, called Global Warming. When we scrap the old to accept the new, greenhouse gases like CO2, Methane and Nitrous Oxide are emitted in the process, contributing to Global Warming. In today’s era, computers have become an integral part of our life to solve our various problems. Everyone uses computers for their own purpose without being aware of the harmful side effects, impacting the environment. As increase in the number of computer user’s around the world, the consumption of electricity also increases. Ultimately, increase in carbon emissions in the surroundings. Controlling the CO2 emissions is one of the first of many steps that we must take in order to combat global warming, which can be done by practicing Green Computing. Green computing refers to an environmentally sustainable computing. It is the study and practice of design, manufacture, use, and dispose of computers efficiently with minimal or no impact on the environment [11]. In this paper, we discuss the different aspects to understand “Green Computing”. Also, questionnaire has been done on the awareness of Green Computing. Comparative data has been collected before and after practicing Green Computing. We are promoting Green Computing in The Community College for Girls, Khamis mushyat, KSA, through seminars and are implementing the techniques as well. Also, propagating awareness to neighbors, friends and relatives. Green computing approaches aid us to make a secure place to inhabit. Consequently, Green computing is the eventual requisite to defend the environment and save energy.
