The authors have tried to strike a balance between a short book chapter and a very detailed book for subject experts. There are three prime reasons behind for doing so: first, the field is quite interdisciplinary and requires simplified presentation for a person from non-parent discipline. The second reason for this short-version of a full book is that both the authors have seen students and technically oriented people, who were searching for this type of book on hydro energy. The third reason and motivation was considering engineers who are starting their career in hydro energy sector. This book is targeted to present a good starting background and basic understanding for such professionals.

This monograph addresses the needs of readers interested in wind energy converters. The authors achieve to strike a balance between a concise presentation of the material and a detailed book for experts in the field. The book covers aspects such as design and technical challenges of wind converters, but also policy issues as well as life cycle assessment considerations. In the past few decades, growth in the wind energy sector has been most phenomenal among all renewable energy resources. In this context, it is nearly universally agreed that wind energy can definitely play an important part in ensuring a sustainable future.The topic is highly interdisciplinary and requires an accessible format for non-experts. Hence, this compact version is suitable for many students and practitioners who intend to read concisely on wind energy.

The present book was written to address the needs of those readers interested in wind energy converters. The authors have tried to strike a balance between a short book chapter and a very detailed book for experts in the field. There were three prime reasons behind doing so: first, the field is highly interdisciplinary and requires a more accessible format for non-experts. The second reason for this more compact version is that both authors have encountered many students and technically oriented people who were searching for this type of book on wind energy. The third reason and motivation for writing this book was to provide some initial information to people who are embarking on a career in the wind industry. It is this group of people that the present book is targeted at.

Noch immer vergeht kein Tag ohne Meldungen in der Tagespresse iiber Umwelt aspekte. Fast keine Ausgabe von energietechnischen und energiewirtschaftlichen Fachzeitschriften erscheint mehr ohne Beitrage zu speziellen umwelttechnischen Verfahren, zu umweltpolitischen Entscheidungen, die einzelne Detailprobleme betreffen, und zu ihren Folgen. Was fehlt, ist eine fachiibergreifende sachbezogene Darstellung der Fakten, die eine vergleichende Einordnung von einzelnen Problemen erm6glicht. Diese Liicke wollten wir fiillen. So erschien unser Buch erstmalig im Jahre 1992, als Sachbuch geschrieben, urn auch Niehtfachfrauen und -manner anzusprechen. Der Anfang geht aber bis in die siebziger Jahre zuriick, als wir fUr eine Informationsveranstal tung erstmals unter dem Titel Energie und Umwelt einen Uberblick erarbeite ten. Damals standen die Umweltbelastungen der Stromerzeugung mit Kohle und Kernenergie im Vordergrund. Dies hat sich inzwischen erheblich geandert - das Spektrum der Fragen ist breiter, tiefer und angemessener geworden. In der zweiten notwendig gewordenen Auflage haben sich in Teilgebieten Ver schiebungen ergeben. Wintersmog ist beispielsweise dank der bisher erreichten Emissionsminderungen kein Thema mehr. Der Sommersmog dagegen ist ein Thema geworden. Diesen Entwicklungen haben wir Rechnung getragen. Auch haben wir den Wunsch von Studenten an Fachhochschulen und Universitaten, einige Themen zu vertiefen, erfUllt. Das Sachbuch ist damit zu einem Fachbuch geworden. Geblieben aber ist der verstandliche Stil der Darbietung des Stoffs."

Optimierungsmodelle werden immer hAufiger zur Beschreibung des Verhaltens komplexer Systeme herangezogen. Dieses Buch beschAftigt sich mit den MAglichkeiten und Grenzen des Einsatzes umfangreicher Optimierungsmodelle zur Beantwortung umweltrelevanter Probleme der Energieversorgung. Am Beispiel des in der Systemanalyseforschung in JA1/4lich entwickelten MARNES-Modells wird fast lehrbuchhaft der Weg von der vorgegebenen Fragestellung A1/4ber die Modellierung selbst bis hin zur Anwendung aufgezeigt. Breiten Raum nehmen die AusfA1/4hrungen zum Linearen Programmieren und zur datenmAAigen Charakterisierung der Technologien ein. Mit diesem Buch liegt erstmals eine detaillierte Beschreibung eines Energie- "und" Umweltmodells vor. Das Buch wendet sich an Wissenschaftler in der Systemanalyse und im Operations Research genauso wie an die Praktiker in den Planungsabteilungen der Energiewirtschaft und in den verschiedenen Affentlichen Institutionen.
