Renewable energy sources (RES) are of great interest across the world, since it can be used to obtain clean, green energy, thus minimizing the environmental pollution. Romania has an important potential for development of renewable energy, in the hydro, wind, solar, geothermal, and biomass fields. But the market of RES expands or shrinks being influenced by policies, technologies and financial support change. The transposition of Directive 2009/28/EC of the European Parliament on the promotion of the use of energy...

This paper presents an assessment of power generation losses of a hydropower plant (HPP) due to an imposed reservoir management plan and comparisons in terms of monetary value with the existing management plan but with an eutrophic reservoir. The study case is represented by Gole?ti reservoir, which is a shallow reservoir in Romania, and the associated HPP. Gole?ti reservoir is an artificial lake of medium size, which has a 55пїЅ106 m3 volume and a maximum depth of 32 m. Its use is complex: it allows flood control...

Many informatics tools have been developed based on extensive databases related to terrain modeling and technical objects of the existing hydropower developments. Among them, VAPIDRO-ASTE can be distinguished as a powerful and demonstrated tool, which can be used either for the evaluation of the hydropower potential and the optimization of the complex hydropower development of a river sector, or for the evaluation of an existing hydropower development in order to establish the need of the refurbishment and/or reha...
