This book focuses on spatial planning – an important determinantof energy saving and renewable energy supply. Revealing the key driving forcesfor spatial development supporting the shift towards energy efficiency andrenewable energy supplies, it shows the importance of integrated spatial andenergy planning approaches for a timely and sustainable change of energysystems, thus supporting policies of climate protection. As operating withinthe context of renewable energy sources is becoming a major policy issue at theinternational, European and national level, spatial dimensions of renewableenergy systems as well as challenges, barriers and opportunities in differentspatial contexts become more important. This book analyses not only thefundamental system interrelations between resources, technologies and consumptionpatterns with respect to energy, but also the links to the spatial context, andprovides guidelines for researchers as well as practitioners in this new,emerging field. It presents innovative analytical tools to solve real-worldproblems and discusses the most important fields of action in integratedspatial and energy planning including planning contents, planning visions andprinciples as well as planning process design and planning methodology.
