Sustainable development of the Prefecture of Kephalonia
An optimisation methodology is applied on the islands of Kephalonia and Ithaca (Prefecture of Kephalonia) in Greece, where various Renewable Energy Sources (RES) can be found and could be exploited to satisfy part of their energy needs. These resources are examined and a case study is performed for Kephalonia that involves an application of specific mathematical tools that will lead to a set of energy solutions. Many scenarios of cases were examined where the requirements of certain end uses were increased and also cases where some of the renewable energy systems were not at the maximum of their potential.
Multicriteria analysis of Renewable Energy Sources (RES) utilisation in waste treatment facilities: the case of Chania prefecture, Greece
Greece's current solid waste management system faces important environmental challenges that make it non-sustainable. There is a need to move towards an integrated solid waste management that shall include systems in the frames of 'sustainable development' approach. An optimisation methodology is applied in Greece, where various Renewable Energy Sources (RESs) could be exploited to satisfy part of the existing and proposed waste management facilities' energy needs. An application of multicriteria analysis and many scenarios were examined in the cases where the requirements of certain end uses were increased and where RES could not contribute at the maximum of their potential.
Global energy and carbon dioxide
The relationship between increasing CO/sub 2/ concentrations in the atmosphere and possible major geophysical and biospheric consequences--the so-called greenhouse issue--has been a question of growing popular and scientific concern. The combustion of fossil fuels is currently the major source term in the atmospheric carbon cycle. This link between energy combustion and carbon concentrations means that most CO/sub 2/ questions of interest to policymakers require the ability to say something about future rates of energy use and the fuel mix. The rapid mixing of CO/sub 2/ in the atmosphere requires that the energy analysis be global. Finally, the cumulative and, to the large extent, irreversible nature of the problem requires a long-term perspective. As with any projection, there are inherent uncertainties; but the very long-term nature of the CO/sub 2/ issue make uncertainty a dominant consideration.
