This book focuses on spatial planning - an important determinant of energy saving and renewable energy supply. Revealing the key driving forces for spatial development supporting the shift towards energy efficiency and renewable energy supplies, it shows the importance of integrated spatial and energy planning approaches for a timely and sustainable change of energy systems, thus supporting policies of climate protection. As operating within the context of renewable energy sources is becoming a major policy issue at the international, European and national level, spatial dimensions of renewable energy systems as well as challenges, barriers and opportunities in different spatial contexts become more important. This book analyses not only the fundamental system interrelations between resources, technologies and consumption patterns with respect to energy, but also the links to the spatial context, and provides guidelines for researchers as well as practitioners in this new, emerging field. It presents innovative analytical tools to solve real-world problems and discusses the most important fields of action in integrated spatial and energy planning including planning contents, planning visions and principles as well as planning process design and planning methodology.

From 1909 to 1912 Paul Tillich devoted himself to an intensive study of Friedrich Schellinga (TM)s idealistic philosophy; this process of engagement led to the foundations of his early Christology. The objective of the present study is to interpret the development of Tillicha (TM)s early approach to Christology against the background of Schellinga (TM)s philosophy, and its systematic elaboration right up until his late work. The appendix contains Tillich's hitherto unpublished doctoral files from Breslau and Halle.
