Some 750 exhibitors - a fifth more than last year - will present their wares in the coastal city until Saturday. The increase in participation comes from a worldwide boom in wind energy, with a larger presence of exhibitors from the United States and China.
A main focus at the exhibition will be network connections between wind energy parks. Organizers expect participants to seal deals worth around €3 billion during the week. Some 20,000 visitors are expected to attend.
State premier for Schleswig-Holstein Peter Harry Carstensen said that the country's most northerly state gets about 40 percent of its energy from wind, and predicted the state would have more wind energy than the state can use by 2020 thanks to planned wind parks.
