Title: Contribution to the Chapter on Wind Power Energy

Over the last 5 years the growth rate in wind energy has been as high as 30 % an on average nearly 25 % in all continents, and a considerable number of countries have very ambitious goals concerning their wind energy development, therefore it could be likely to cover as much as 20 % of the world’s electricity consumption by wind in 2030 and 35 % in 2050, although on the shorter term growth is expected to take place mainly in Europe, USA and China. The market is maturing, therefore achieving more stable economies in the wind energy sector. As a result, better electrical grids suited for wind power are being developed and better planning tools as well as other frameworks, which benefit the market for installation of wind turbines, are being implemented across all wind energy countries. The cost of wind-generated electricity has fallen steadily for the last two decades, driven largely by technological advances, increased production levels and the use of larger turbines. Between 1985 and 2005, production costs energy from of win
