The inaugural International Wind Energy Exhibition recently concluded in Hamburg, Germany. This Hamburg International Wind Energy Exhibition attracted a total of exhibitors from 30 countries and regions, with more than 1200 companies participating and 4 ten thousand visitors attending. In addition to showcasing innovative new products, the exhibition also demonstrated future trends in wind energy.

In the host country, Germany, wind energy technology has become the "showcase" of its mechanical manufacturing industry. German Vice Chancellor and Federal Minister for Economic Affairs and Energy Gabriel said at the opening ceremony: "Wind energy worldwide is valued from both economic policy and energy policy perspectives, and has achieved remarkable success over the past 20 years." The German government strongly supports the development of wind energy, proposing a binding timetable for the energy transition by reforming its Renewable Energy Sources Act. Over the past 10 years, wind turbine equipment has grown larger in size, and technology has significantly improved. The height of new wind turbines increased from 80 meters to 135 meters, blade length increased from 45 meters to 60 meters, and turbine power increased from 150 ten thousand watts to 300 ten thousand watts. The new generation of blades exhibited at the show had an area equivalent to two football fields. As a result, the wind-catching area of the blades correspondingly increased, allowing operation even in inland areas with low wind speeds. In the coming years, the global wind energy market has huge growth potential. Statistical data from the World Wind Energy Association shows that wind power currently meets approximately 4% of global electricity demand. It is estimated that by 2020, wind power generation capacity will double again.

Reducing costs is crucial for the future development of wind energy. Hermann Albers, President of the German Federal Wind Energy Association, said: "Over the past 20 years, due to technological improvements, the cost of wind power generation has decreased by approximately 55% to 60%. In the coming years, the cost in the wind power industry will decrease by approximately 2% to 3% annually." According to calculations by the Berlin-based Progonos economic consulting institute, wind power generation has become one of the cheapest forms of power generation. Compared with traditional power generation forms, the cost of wind power generation can be even more than 50% cheaper.
