1.1. Problem Statement<br />

CHAPTER 1<br />

INTRODUCTION<br />

Acknowledging the ultimate importance of <strong>energy</strong>, especially in the last century,<br />

this thesis focuses on the interaction between land-use planning and the <strong>energy</strong>. Within<br />

the context of this thesis firstly present planning approaches are criticized and existing<br />

problems of insufficient relationship between <strong>energy</strong> and planning are analyzed. Then,<br />

the issue is questioned in the particular case of geothermal <strong>energy</strong> utilization.<br />

Disintegration problem is defined based on three major subjects such as geothermal<br />

<strong>energy</strong> district heating system (GEDHS) which includes geothermal capacity,<br />

geothermal infrastructure system, land-use planning and related policies.<br />

Improvements in effective use of <strong>energy</strong> and existing renewable <strong>energy</strong> sources<br />

have been one of the major research topics <strong>for</strong> sustainable urban developments. In this<br />

context, The <strong>process</strong> of World Energy Conference in Munich (1980), the preparation of<br />

“In Our Common Future- Brundtland Report” by World Commission on Environment<br />

and Development (1990), the “Earth Summit” by The United Nations Conference on<br />

Environment and Development (UNCED) in Rio de Janeiro (1992), Agenda 21 in<br />

Geneva (1992), Framework Convention on Climate Change (1994), World Climate<br />

Conference (1995), Habitat II Conference on Human Settlements in Istanbul (1996) and<br />

the “Kyoto Protocol” (1997), the other international conventions started all over the<br />

world because of the wake of the oil crises (1973) and Chernobyl Accident (1986) and<br />

the “low <strong>energy</strong> path” is proposed as the best way towards a sustainable future <strong>for</strong><br />

<strong>energy</strong> efficiency and renewable <strong>energy</strong> concept.<br />

However, the <strong>energy</strong> concepts are not well integrated into planning <strong>process</strong> in<br />

detail with all parameters, such as effective <strong>energy</strong> consumption, efficiency, equality<br />

and conservation as the indicators <strong>for</strong> the relationship between <strong>energy</strong> and planning<br />

<strong>process</strong> in all levels; <strong>for</strong>m, design and planning (Odell 1975, Owens 1986, Sadownik<br />

and Jaccard 2001, Means 2004, Peker 2004). There is strong relationship between<br />
