The total installed capacity for wind power generation in the world exceeded 34GW at the end of September of 2003, including 500MW installed in Japan. A challenging proposal was made in 2002 by EWEA (European Wind Energy Association), which is a blueprint to achieve 12% of the world's electricity from wind power by 2020. According to this report, Japanese wind power capacity should reach 30GW by 2020 while our present projection is only 3GW by 2010. However in actuality, many failures of the wind turbines have been reported since the utilization of the wind power began in earnest in the latter half of 1990's and the capacity factor sometimes fell short of our expectation. In this report, to accelerate the utilization of the wind power generation, we clarify the actual situation of the availability factor in Denmark, which is most advanced in wind power generation, and in Japan evaluated technologically. Additionally, existing problems and prospects for the wind power generation are surveyed as well.
