The (r)evolution of wind energy systems in Romania: State-of-the-art, new trends and challenges

Abstract

After decades of development, one of the most mature renewable energy technologies is recognized to be wind energy. Compared to other renewable energy sources the wind potential that can be used to produce electricity is much higher. Currently, the conversion of wind energy into electricity has several advantages, among which can be mentioned the following: "clean"energy source, renewable energy source, low costs per unit of electricity produced. Thus, the progress of future technological innovations must lead to the achievement of wind turbines that are more efficient, more robust, and less expensive than actual technology. The aim of this work is to provide an overview of the Global, European and, especially, Romanian situation of the wind energy market. Moreover, are presented aspects related to innovative constructive solutions for wind turbines used to capture wind energy in areas where wind potential is low.
