The main objective of the present work is to provide a more comprehensive picture of the Romanian energy system, a special attention being given to the emerging renewable sources. As a first step, different indexes will be considered to highlight the structure of the electricity portfolios, from which the authors mention electricity access and consumption and the dioxide emissions. The obtained results will be discussed at both regional and European levels, by taking also into account the share of electricity coming from renewable sources. If one discusses about renewables, it is important to mention that most of the Romanian projects are located onshore, but since there is access to the Black Sea, the benefits coming from a marine project need also to be discussed. Finally, the authors conclude that the Romanian energy market is defined by various opportunities and challenges and, using the renewable sources, it will be possible to build a sustainable energy industry.
The objective of the present work is to estimate the benefits which may be obtained from the implementation of a solar and wind project, by considering several reference sites, located in the southeastern part of Romania. In the first case study, the attractiveness of the solar energy will be evaluated for a production factory located in the vicinity of Galati city. The seasonal and annual fluctuation of solar energy will be discussed, by taking also into account the performances of a photovoltaic panel, which may be installed on the roof of these production halls. As for the second case study, the performances of some state-of-the-art wind turbines will be evaluated by taking into account three sites located along the Romanian shoreline, namely Sf. Gheorghe, Navodari and Vama Veche, respectively. According to these results, it was noticed that the photovoltaic panels will partially cover the energy demand for the selected factory, while in the case of wind energy, a single wind turbine defined by a rated capacity of 3 MW seems to easily cover the local electricity budget, reported in Sf. Gheorghe and Vama Veche.
