From the last decade of 20 century, an introduction of wind power greneration was accelerated both in developed countries as well as developing countries. Among these countries, we call Denmark as "Kingdom of Wind Power Generation". The cumulative wind power capacity in Denmark reached 2500MW at the beginning of 2003 and covers 14% of the country's electric demand. A capacity level of 3000MW is very close because of three large scale offshore windfarms in the planning stage. Thus, the share of wind powered electricity will reach 20% in 2004. Moreover, the Danish made wind power plants monopolize the world share of wind power plants market as large as 65%. The reason why Denmark arrived such wind power country could be revealed from the historical point of view. In 1860', Denmark was defeated by Prussia and lost the most large and fertile two states. At that time, N. Grundvig, the father of Denmark, rose up and established famous "Folk Highschool" for Danish farmers on the slogan of "From the limited outside to infinite inside". Then, P. la Cour, who was famous physicist moved to Askov Folk Highschool and established world first wind power plant test laboratory in 1891. In the first half of 20 century, Denmark was the only one country which utilized wind power generation, especially during WW1 and WW2, when the wind power utilization had activated because of German effect. After WW2, J. Juul, an engineer of SEAS and student of P. la Cour, investigated the AC grid connection type wind power generation system. Thus, wind power generation in Denmark was fully bloomed on such ground just after the oil crisis of 1970's. At the beginning of 1980's, Danish wind power industry was established. Now, even the technical standard of wind turbines of IEC(International Electro-technical Commission) was based on Danish wind turbine manufacturer's domestic standard. We are now faced with big transition of basic resources as essential as food. That is the transition of energy systems from hunting fossil fuels and nuclear materials in the ground to harnessing energy poured from the sun to the earth. We must learn the Danish experience in the field of wind energy.
