风能及其利用

Wind Energy and Its Utilization

风能是一种清洁、资源丰富、不产生温室气体的自然可再生能。在当前矿石能源面临枯竭、环境日益恶化的情况下,无论从经济上或是技术上都是一项可以首选的替代能源。全球均在对其加速开发和利用。笔者介绍了风的成因和特性,风能的估价方法及全球和我国风能的资源量。并着重介绍了全球和我国风力发电技术的进展过程、发展趋势和前景。此外还扼要介绍了风力提水、风帆助航及风力致热等利用风能的技术和现况。

Wind energy is a clean, abundant resource of renewable energy. It does not produce greenhouse gases. Economically and technically, the wind is a preferred alternative energy in the current days because of the depletion of mineral resources and deteriorating environment. So the development and utilization of wind energy are accelerating all over the world now. In this article, the causes and characteristics of the wind are described, the valuation method of wind energy reserves and wind energy in China and in the world are presented. In the mean time, the wind power technology, trends and prospects are focused on. In addition, the use of wind energy technology and the present situation are introduced, such as wind power water-lifting, wind-aided sailing and wind power heating.
