A 150 kW Wind World turbine which failed to live up to expectations was taken down last month, nearly four years after being installed at Timmernabben on the east coast of Sweden in April 1992 in. The poor production has been blamed on inflated wind estimates made prior to installation by the Swedish meteorological institute. The institute had based its calculations on a formula devised for the flat Danish landscape and had failed to take Sweden's more complex terrain into account. The owner decided it would be more profitable to have the machine moved to a windier site. The wind turbine had also attracted complaints about noise from the owners of a nearby group of weekend homes, despite the efforts of Wind World to reduce sound levels. The co-operative which owned the machine are in no hurry to find a new site. They have since invested in a new 500 kW Wind World unit at Kastlösa on Öland, one of the windiest places in Sweden.
