风能是自然能源之一。利用风能为人类生产服务已有悠久的历史,最早是利用风力推动帆船,以后逐漸发展到风磨和风力水車,近几十年来风力发电也已成功。地球上近地层每年可利用的风能总量据估計約有50×10~(13)千瓦/小时左右,而1958年全世界所需要的总能量約为3×10~(13)千瓦/小时。实际上,現在每年为人类所利用的风能是微乎其微的。其最主要的原因是风能的不經常性与分散性。但由于风能是取之不尽,用之不竭的,而且随处都有,不象利用石油、煤等动力資源必需解决运輸問題;风力机不要求优貭鋼,中小型风力机制造容易,管理方
Wind energy is one of the natural energy sources. The use of wind energy for human production has a long history of service. The earliest uses of wind power to propel sailing boats and the subsequent development of wind mills and windmills have led to the success of wind power generation in recent decades. The total amount of wind energy available annually on the earth’s upper and lower strata is estimated to be about 50 × 10 ~ (13) kW / h, whereas the total energy required around the world in 1958 was about 3 × 10 ~ (13) kW / h. In fact, the amount of wind energy that is used by mankind today is negligible. The main reason for this is the irregularity and dispersion of wind energy. However, as wind energy is inexhaustible and inexhaustible everywhere, unlike the use of oil, coal and other power resources must solve the transportation problems; wind turbine does not require excellent steel, small and medium-sized wind turbine manufacturing easy, Management side
