The purpose of this research was to analyze whether the use of technological resources may be feasible in the implementation of the environmental culture cross-cutting factor for sustainable development, which focuses on environmental issues related to the contents of the Science study program for the seventh year of the basic general education. The research design is qualitative with a dominant approach and uses some quantitative elements specifically in the design of instruments and some data analysis techniques. The type of study was developed with a multi-method approach; a trend that has been shaping a research style which integrates various methods in a single design. For this, we identified the didactic strategies and their relationship to both, technology and the environmental axis for sustainable development, used by six Science teachers of the 7th grade, in public institutions of the province of Heredia, Central Valley, Costa Rica, as well as the opinion of 20 students from that same grade. The main results include the opinions of the students, who showed a considerable interest in classes where technological resources are used. However, teachers do not show great interest or positive opinions on this matter; in addition, they are not well trained on the use of technological resources. It was also identified that the teaching personal who participated in the study do not develop this curricular axis.

Considering the wide implications of global warming it is evident the need, not only of diminishing the energy consumption patterns, but of diversifying to “sustainable” energy resources. Moreover, within the frame of national security, this requires tore-think the managing and use of available resources, because any change of the energy paradigm will depend, at least at the beginning, on fossil energy.Considering the above, the following paper opens a discussion about energy, entropy and the limits of economic growth, following the premises of the school of ecological economics. It offers several empirical data about the situation of the current energy pattern, mostly about its socio-environmental aspects. The paper ends discussing the characteristics and limitations of the main available alternative energies; meanwhile it highlights the relevance of contemporary patterns of territorial organization. It concludes pointing out the inherent need of diminishing the type and rhythm of current energy consumption.
