风能是巨大的资源,仅仅1%的地面风力就能满足全世界的能量需求。风能不仅极其丰富,而且不会造成任何污染,在国际范围内,风能利用在迅速增长。美国现有1.7万多台风力发电机,发电容量达1700MW,估计到2050年,风力将为美国提供16%的能源。美国联邦实验室的专家预测未来五年内进入市场的叶轮机将比现在使用的更大、更轻,塔高将达61米,并
Wind energy is a huge resource, and only 1% of ground wind power can meet the world’s energy needs. Wind energy is not only extremely rich, but it does not cause any pollution. In the international context, wind energy utilization is growing rapidly. The United States currently has more than 17,000 wind turbines and a power generation capacity of 1,700 MW. It is estimated that by 2050, the wind will provide 16% of the energy for the United States. Experts from the U.S. Federal Laboratory predict that the turbines entering the market in the next five years will be larger and lighter than those currently used, and the tower height will reach 61 meters, and
