A single educational activity in the computer lab to reduce energy consumption

Floriana Nascimento Pontes, Fabio Giordano

Abstract


The sustainable development concerns, in particular those to the maintenance of natural resources, have been demonstrated recently in many ways due to the population needs of energy saving. This work addresses the importance of this economy to reduce business costs and highlight how much the damage caused by waste to the environment and the need for environmental education and awareness are also relevant in the context of personal awareness itself. The method used to evaluate energy reduction was the application in a computer lab the measure of time wasted by students during the moments in which the monitors were turned on unnecessarily. The total time of unnecessary spent of electric power was estimated in 120 minutes on a class activity of approximately 35 minutes, for a group of 27 students. In accordance with consumption and savings data of the National Electric Energy Agency of Brazil, 120 minutes were converted into kwh and the result was presented as the possibility of reducing 1.6 kwh in a weekly class where the monitors were turned off during the times when students do not effectively use the computer and were engaged only in discussion and exchange of ideas. This reduction could be projected to a month period, a semester, as well as to similar disciplines, and could result in big savings contributing to the sustainability of the planet and also a qualitative gain awareness for a large number of students users of these laboratories.
