Many organized sectors in society have pointed out the alterations caused by the human being in nature. Among these charges we would like to highlight those directely related to the production of electric energy in large scale. The debate on the issue is limited, most of times, to tecnicians and academics. However many people feel the problems caused by the use of diverse tecnologies of eletricity production. Considering the orientations of current curricular proposals, we seek in this paper to indentify and systematize the main elements of the discussions being held by technician and academics about electric energy production in large scale, and its relationship with environmental issues, which could be transformed school contents.
