The first international wind energy exhibition in Hamburg before the curtain falls. The Hamburg International Wind Energy Exhibition has attracted more than 1200 enterprises from 30 countries and regions, and 40 thousand visitors will participate in the exhibition. In addition to exhibiting creative new products, this exhibition also shows the trend of future wind energy development.
In the host country, wind energy technology has become a "sign" of its machinery manufacturing industry. Gabriel, German Deputy Prime Minister and Minister of the federal economic and energy department, said at the opening ceremony: "world wind energy has been valued both in terms of economic policy and energy policy, and has made brilliant achievements in the past 20 years." The German government has strongly supported the development of wind energy and put forward a binding timetable for energy transformation through the reform of its national renewable energy law.
In the past 10 years, the wind power equipment has become more and more large, and the technology has been greatly improved. The new windmill height from 80 meters to 135 meters, fan leaf length increased from 45 m to 60 m, turbine power from 150 kW to 300 kW increase. The new generation of fan leaves on show at the exhibition are as large as two football fields. In this way, the wind area of the wind is increased, and it can also be maintained in the area with small inland wind. In the next few years, the global wind energy market has a huge potential for growth. Statistics from the world wind power Association show that the current wind power has been able to meet about 4% of the global demand for electricity. It is expected that by 2020, the wind power generation capacity will double.
Reducing the cost is crucial to the future wind energy development. Hermann Albers, chairman of the German Federal wind energy Federation, said: "over the last 20 years, the cost of wind power has been reduced by about 55% to 60% due to technological improvements. In the next few years, the annual cost of the wind power industry will be reduced by about 2% to 3%. " Wind power has become one of the cheapest forms of power generation, according to the calculation by the Berlin Progonos Economic Advisory Institute. Compared with traditional power generation, the cost of wind power generation can be even more than 50%.
Data from the German Federal wind energy Federation showed that the country's wind power installed capacity increased significantly. This year is expected to amount in the breeze electric machine will reach 3.5 MW offshore wind power installed capacity is expected to reach 1 mw. This scale of wind power can replace 3 large nuclear power plants or coal and electricity plants. Albers expected that next year, the German wind power installed capacity is still expected to exceed 3 megawatts. Although the growth figures are considerable, the wind power industry is also facing a lot of problems.
In the past few years, the wind power industry in European and American countries has gone through a big rise and fall. The main reason is the lack of policy support and market distrust. The German Federal Wind Energy Association hopes to create a stable framework for the development of wind power, and develop a directive renewable energy industrial policy in Europe.
China's wind power has been flourishing in recent years. Steve Sawyer, director general of the Global Wind Energy Council, said the global wind market has been gaining momentum driven by China. The wind power market in Latin America, Africa, and especially in India is booming. "No one could expect it 10 years ago." According to statistics, in 2013, the volume of wind power installed in China almost half of the total installed capacity of the world, a year installed capacity of 16 megawatts. According to the latest world wind energy report, this year, the volume of wind power installed in China will remain at the same level as last year.
It is reported that the Hamburg International Wind Energy Exhibition in Germany will be held every two years, and will become an important platform for the global exchange.
