Introducción La creciente tensión generada por el estilo de desarrollo contemporáneo y los acelerados cambios sociales y tecnológicos han impuesto límites a la reproducción de la vida en el planeta y al uso indiscriminado de los recursos naturales. Esas contradicciones entre la interacción de las formas sociales de acceso, apropiación y uso de los recursos naturales y la disponibilidad de medios y recursos para el desarrollo afectan de manera diferente a los distintos actores sociales.

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.
