Wind energy compared with other, has its obvious advantages: Yun huge, renewable, widely distributed, no pollution. Wind and sun, is inexhaustible of renewable energy wind power without fuel, will not produce radiation or carbon dioxide pollution, radiation or does not produce air pollution but also from the economic point of view, wind instruments Cheaper than solar energy equipment to more than 90%. China's wind energy reserves of great, wide distribution, even more water to enrich. Rational use of wind energy, can reduce environmental pollution, ease the increasing pressure of energy shortages.
According to the National Weather Service to the information provided: China's land-based 50-metre high wind resources available for more than 250 million kilowatts, the sea wind resources are more than 750 million kilowatts, far more than can make use of hydropower resources of 378 million kilowatts.
In China, about 20 percent of the country's land area is rich in wind energy resources, mainly in the southeast coast and its islands, northwest, north and northeast China, "Three North" region, especially in Xinjiang and Inner Mongolia, wind resources are very rich. Wind energy, as a non-polluting, renewable and low-cost operation of the new energy resources, has great development potential and broad market prospects.
At present, China's rapid development of wind energy use, both in the scale of development or level of development, have greatly improved. In 2004, construction projects in the country of about 1.5 million kilowatts installed capacity, which is the construction of about 420,000 kilowatts, the Institute approved 680,000 kilowatts, the project proposals approved the 450,000 kilowatts, including five 100,000 kilowatts concession Some of these projects have been completed and completed by the end of 2005 China's Fan reached 1.266 million kilowatts installed capacity.
Wind energy development still needs time ripe
China's wind power industry development situation is very good. Wind energy in the third General Assembly, the exhibition product range, various fan equipment, supporting the full range products, but in these busy behind the weak wind power equipment industry is dragging its hind legs. Despite 20 years of construction and development, China's wind power market is still in an immature state. Compared with developed countries, China's wind energy development in terms of technology, scale, level or in the pace of development still exists a wide gap between. The harsh reality is that the domestic power generation equipment is becoming a low level of China's wind power industry of the main obstacles.
A strong wind energy industry is an important foundation for industrial development. Germany, Spain, the Netherlands, Denmark and the United States experience has shown that wind energy industry, without exception, to have a solid technical strength and strong support for the manufacturing sector. In China, the manufacturer because of insufficient long-term investment, non-specialized factories, production is small, too scattered, low levels of concentration, backward technology, product quality instability, low economic efficiency. Therefore, China's wind industry source localization of manufacturing of low, making it difficult to reduce the project cost and the timely provision of spare parts.
High-cost, high prices are restricting technology commercialization and promote the use of the biggest obstacles. Compared with similar technology, wind energy production costs are much higher than fossil fuels. The cost of wind power generation is coal-fired electricity 1.7 times, which weakened the wind part of the promotion of economic competitiveness. There are many reasons for the high cost, small-scale production is an important reason. Wind energy production costs are still high. As low-energy conversion efficiency, to improve the conversion rate, on the need to increase the complexity of the system, leading to rising costs.
Wind Energy Association said the Secretary-General Qin Haiyan, "wind power industry in China's development will not be plain sailing." Manufacturing as an example to fans. As of 2005, apply to the competent authorities and the so-called wind generators manufacturers to enter the field of large and medium-sized enterprises have more than 50. However, even the most optimistic estimates, China's domestic market will not accommodate too many complete machine manufacturers.
Despite facing various difficulties, but in the renewable energy law promulgated and implemented the positive, renewable energy, particularly in the development and utilization of wind energy will surely usher in a period of rapid development. It is learned that China has wind power as the focus of new energy power generation and to develop a long-term development plans, in more than 10 provinces (autonomous regions) plans to build windmills. According to experts predict that 50 years, wind power generating capacity will account for the total generating capacity of 30 to 40 percent.
