Wind energy in China: Current scenario and future perspectives

Wind power in China registered a record level of expansion recently, and has doubled its total capacity every year since 2004. Many experts believe that China will be central to the future of the global wind energy market. Consequently, the growth pattern of wind power in China may be crucial to the further development of the global wind market. This paper firstly presented an overview of wind energy potential in China and reviewed the national wind power development course in detail. Based on the installed wind capacity in China over the past 18 years and the technical potential of wind energy resources, the growth pattern was modeled in this study for the purpose of prospect analysis, in order to obtain projections concerning the development potential. The future perspectives of wind energy development in China are predicted and analyzed. This study provides a comprehensive overview of the current status of wind power in China and some insights into the prospects of China's wind power market, which is emerging as a new superpower in the global wind industry.

展望未来中国能源“绿色版图”(下)——记“十二五”规划可再生能源发展座谈会

<正>中国可再生能源学会太阳能建筑专委会秘书长张磊开发高性能高效多样化太阳能建筑一体化产品从和建筑结合的角度看,可再生能源产品建筑应用主要面临这样几个问题:一、产品进入建筑就必须要纳入建筑工程,这对产品的要求会更高。虽然光热全部替代可以解决建筑采暖、空调、热水等80%的能耗,但建筑可使用面积是有限的。按现有的太阳能采暖技术配备集热器的面积,没有足够空间。

Wind energy development in China — Reality and market forces

Economic reforms in China started in 1978, which led to profound changes as a result of a consistent structural adjustment and stabilisation policy. The national economy is now characterised with high growth and low inflation. In 1997, GDP was US$ 767 billion and foreign exchange reached US$ 140 billion. This paper examines the outstanding contribution of rural industries to rapid growth of national economy and the consequences of increase of energy consumption and its environmental impact. It also emphasises the necessity and benefit of using renewable energy and wind energy in particular. The paper also addresses the issue of joint venture in farm development in line with Chinese market economy.     

Wind energy potential in Palestine

Weibull parameters of the wind speed distribution function were computed for 49 weather stations in Palestine. Wind potentials in kWh/m² yr were calculated at the above stations, then contours of wind potential were drawn. Electricity from the wind can be generated, in some locations in the West Bank, at a cost of 0.07 $/kWh.     

Wind energy assessment in Turkey

Long-term wind speed measurements from 117 stations in Turkey have been evaluated in order to find prospective sites for building large scale wind-power machines. Based on these measurements, monthly mean isopleth maps as well as an annual mean density map for wind speed have been produced. Using the Weibull distributions, the available annual mean power and the variations with altitude have been computed for the selected stations. Finally the applicability of these systems to this country is discussed.     

Wind energy potential in Tunisia

The purpose of this paper is to constitute a database for the users of the wind power. It presents the study of 17 synoptic sites distributed on all the territory of Tunisia. From the meteorological data provided by the Meteorology National Institute (INM), two statistical methods (meteorological and Weibull) are presented to evaluate the wind speed characteristics and the wind power potential at a height of 10 m above ground level and in an open area. An extrapolation of these characteristics with the height is also carried out. The results obtained give a global vision of the distribution of the wind potential in Tunisia and define the most windy zones.     

Wind energy development in Pakistan

Pakistan has a very limited fossil fuel resource base. The poor economy does not allow the import of fossil fuels, particularly oil, on a large scale. Moreover, too much reliance on imported oil is critical from energy security point of view. A large fraction of the population lives in remote areas and is still waiting to be connected to the national electricity grid. To help these remote communities in particular, and to overcome energy shortages in general, Pakistan needs to develop its indigenous energy resources like hydropower, solar and wind. More than 1000 km long coastline in south and some places in northern mountainous areas provide an excellent resource of wind energy. This vast potential can be exploited to produce electricity on both community and wind farm scales. Applications other than electricity production, such as water pumping, also have vast applications. This article discusses the past, the present and the future of wind energy use in Pakistan. The efforts for the utilization of wind energy in the country are presented as well, along with barriers to its development. It is concluded that the potential exists, but significant efforts are needed to effectively make use of this cheap renewable energy source.     

Wind energy potential in Aden-Yemen

The wind energy resource is very large and widely distributed throughout the world as well as in Yemen. Aden possesses a very good potential of wind energy. In this article a number of years data on wind speed in Aden has been studied and presented. A statistical analysis was carried out from which the annual wind speed was found to be 4.5 m/s and most of the time the wind speed is in the range of 3.5–7.5 m/s. The wind speed distributions were represented by Weibull and Rayleigh distributions. It was found that the Rayleigh distribution is suitable to represent the actual probability of wind speed data for Aden. The wind speed data showed that the maximum monthly wind speed occurs in the month of February with the maximum in the month of June. It is concluded that Aden can be explored for wind energy applications.     

Wind energy potential in Syria

Both wind energy potential and the electricity that could be generated by the wind for the Syrian land have been evaluated. An appropriate computer program was especially prepared and designed to perform the required calculations, mainly the wind energy potential and the generated electricity, using the available meteorological data provided by the Syrian Atlas. The program is capable of processing the wind data for any specific area, that is of course, in accordance with the needed requirements in fields of researches and applications.Moreover, calculations show that a huge energy potential is available for direct exploitation and as much as twice the current electricity consumption in Syria can be generated by the wind resource.     

Wind energy activities in Japan

This paper describes recent activities on wind energy in Japan. The national “Sunshine Project” conducted by the Ministry of International Trade and Industry, was reviewed in 1990 to map out a new energy strategy in the Age of Global Environment. As a result, a new 500kW WECS R&D project has started in FY1991 and the operation started in FY1996. A number of basic and applied studies have been undertaken at the NEDO, the MEL and many universities. Interests in utilization of wind energy have spread gradually among power company. From FY1991, the Tohoku Electric Power Company has operated a 2,875kW Windpark(5 units of 275kW machine and 5 units of 300kW machine) at Tappi, where the annual wind speed is as strong as 10m/s.Researches and demonstrations are also conducted by some other power companies. MHI has developed middle-sized commercial WTGs. More than 800 units were exported to the United States and UK. IHI also developed 300kW machines. Fuji Heavy Industry is developing new concept machine of small to medium size.

Wind energy status in electrical energy production of Turkey

Main electrical energy sources of Turkey are thermal (lignite, natural gas, coal, fuel oil, etc.) and hydraulic. Most of the thermal sources are derived from natural gas. Turkey imports natural gas; therefore, decreasing usage of natural gas is very important for both economical and environmental aspects. Because of disadvantages of fossil fuels, renewable energy sources are getting importance for sustainable energy development and environmental protection. Among the renewable sources, Turkey has very high wind energy potential. However the installed wind power capacity is only 0.22% of total economical wind potential. In this study, Turkey's installed electric power capacity, electric energy production is investigated and also Turkey current wind energy status is examined.
