Wind Potential of central Eastern Europe

Wind energy the cheapest and the most dynamically developing type of renewable energy sources. It has a large literature related to the protection of the environment, technology, economy, law and meteorology. We wish to present the basics of wind energy utilization. Solar radiation is the driving force of wind energy, heating the surface of the Earth to different values, and creating a pressure difference between the air layers with different temperatures. The horizontal flow for the equalization of the pressure difference is called wind. As an energy source, wind has a low energy density; it changes in place and time; however, it is a free and clean energy. The momentary direction and strength of the wind is defined by four forces. Pressure gradient force causes air particles to flow from areas of high pressure to low pressure areas. (Sándor, Wantuch, 2005)
