Die Wachstumsraten bei der durch alternative Energieträger zur Verfügung gestellten elektrischen Energie sind bemerkenswert hoch, insbesondere im Windenergie-Sektor. Das führt zum einen zu Problemen technischer Natur, wie beispielsweise bei der Einspeisung und der Speicherung elektrischer Energie, zum anderen werden zunehmend mehr kompetente Fachkräfte benötigt, die die Windenergieanlagen an Land und auf See aufbauen und instand halten. In diesem Zusammenhang tauchen Fragen nach der Verfügbarkeit wie auch nach den beruflichen Kompetenzen der benötigten Fachkräfte auf. Ein Ziel dieses Beitrags ist, im Anschluss an einige Bemerkungen zur Kompetenzstruktur und zum Kompetenzniveau von Fachkräften für die Instandhaltung einen Blick auf die gegenwärtig zu beobachtende Praxis bei deren Rekrutierung zu werfen. Dabei werden sowohl Konzepte und Strategien von Herstellern und Betreibern von Windenergieanlagen betrachtet als auch solche von Service-Dienstleistern und Zeitarbeitsfirmen. Darüber hinaus wird versucht, exemplarisch einen Eindruck von Qualifizierungsangeboten im Bereich beruflicher Fortbildung des Windenergiesektors zu vermitteln. Jenseits der Aktivitäten der Akteure von Unternehmen und Bildungsträgern sind die bei der Instandhaltung zu bewältigenden Arbeitsprozesse und damit die Identifizierung beruflicher Kompetenzen aus berufswissenschaftlicher Perspektive weitestgehend unerforscht. In einem letzten Abschnitt geht es daher um den Beitrag, den die Berufswissenschaften in diesem Kontext leisten können.

Tip: This XML query result can't be used as string because for that it had to contain exactly 1 XML node, but it contains 0 nodes. That is, the constructing XML query has found no matches.
