In the last couple of years Romania has witnessed a major change on the renewable energy sources market, in particular in regard to wind energy. Supported by appropriate legislation, the interest of the investors was materialized in a large number of wind farms constructed mostly in the South-Eastern part of Romania and an exponentially increased number of wind energy GW delivered to the national power grid. Although the Romanian authorities are lacking a solid base in what previous experience in the field of wind energy is concerned, the sudden escalation of wind energy production is expected to have a sustainable development and to help Romania, together with primary energy and other renewable energy sources, such as nuclear energy, biomass and hydropower, to become one of the most important energetic poles in South-Eastern Europe and to consolidate its position as one of the top ranked energy security countries in the EU. This paper analyses the impact of wind energy on the economic and energetic sectors of the country, looking at both technical and economic variables and aims at understanding whether the wind energy boom can be supported in the future, at what proportions and to what costs. The background provided for this analysis is the transposition of the European law in regard to the Environmental Impact Assessment Directive into national law and the obstacles that might be associated with it. The paper shows, on the one hand, that there are still a considerable amount of improvements that need to be made, for a steady functioning of all sectors influenced by wind energy, and, on the other hand, that used in a controlled manner, wind energy could be regarded as a win-win situation of Romania (green energy produced and funds attracted).
