Congestion charges in Stockholm
The introduction of congestion charges in Stockholm was one of the reasons why Stockholm was awarded “European Green Capital 2010”. The introduction has led to reduced traffic with somewhere between 20 and 25% and that air quality has been improved, according to the Road Administration.
Restoration of overgrown meadows
At Svartsjöviken in Ekerö municipality, overgrown meadows have been restored. The grounds, which had a low sustainability, were restored with newly developed aphibious vehicles, light band wagons and stump cutting equipment. Today, the meadows are harvested, which has recreated a valuable biotop. At the same time, a long-term parntnership has been established between the municipality, the farmers, the local residents, landowners and various other associations.
Stored heat makes football pitch playable
When the new football field at Katrineholms Sports center was constructed, heating coils underneath the pitch were installed, which makes its playable even in winter. The heat is collected from an underground energy storage, where waste heat from the artificially frozen bandy court’s compressors is stored.
Vertical windpower outside Uppsala
Vertical Wind has developed a new and exciting wind power technology based on a vertical axis wind turbine with a cable-wound direct driven generator. The turbine does not need a pitch or a yawing mechanism and the direct driven generator eliminates the need of a gearbox. The robust and simple technology with few moving and sensitive parts compared to conventional wind turbines, gives a higher availability and reliability as well as lower cost for maintenance. Furthermore, this type of wind turbine is quieter than its horizontal counterpart.
