SUSTAINABLE ENERGY PLANNING MODEL (MODERGIS) APPLICATION TO INTEGRATE RENEWABLE ENERGY IN THE COLOMBIA CASE

摘要

An essential element to reach sustainable development is an appropriate and reliable energy supply. This helps to eradicate poverty, improve human welfare, and to raise quality of life in the population. However, many regions in the world do not have a reliable supply, and its use exceeds economic limits, creating a dichotomy between growth and sustainability. World institutons such as United Nations and its organization UNESCO, have demonstrated that current energy production and consumption models are not sustainable in a medium term. Many countries, especially those that are in development such as Colombia, have a great potential of renewable energy resources that have not been used or incorporated into the energy mix due to the lack of tools to evaluate and to integrate them with a sustainability criteria. Then, "Universidad Nacional de Colombia" (Colombia) and "Centro de Investigaciones Energs|ticas Medioambientales y Tecnols(r)gicas - CIEMAT" (Spain) have jointly developed an integrated energy planning tool named MODERGIS. Its objective is to incorporate, evaluate and analyze renewable vs. conventional energy. This model comprises three constitutive elements: an energy supply-demand model (ENERDEM), an integration and space definition of renewable energy through geographic information systems (ENERSIG), and a multi-objective analysis to optimize sustainability dimensions of energy sources (ENERSOS). The current paper shows some of the preliminary results of this model, and discusses on the methodological issues faced during its development. Further and more expanded results are expected to be published in the near future.
