    Enhanced (or engineered) geothermal systems (EGS) have evolved from the hot dry rock concept, implemented for the first time at Fenton Hill in 1977. This paper systematically reviews all of the EGS projects worldwide, based on the information available in the public domain. The projects are classified by country, reservoir type, depth, reservoir temperature, stimulation methods, associated seismicity, plant capacity and current status. Thirty five years on from the first EGS implementation, the geothermal community can benefit from the lessons learnt and take a more objective approach to the pros and cons of ‘conventional’ EGS systems

    This chapter presents a review of multi criteria decision models used in the energy sector and demonstrates application through the case of geothermal energy. The case is taken from Oregon which is located in teh pacific northwest region of the US. Experts are used to determine the criteria what is important for this application and the region
