Abstract

Energy use is a key factor in tackling the climate crisis and advancing climate goals. Besides technological advancements for the effective and efficient use of energy resources, it is very important for scientific studies to support evolving technologies. Geothermal energy is a renewable and natural energy source that can be used directly or in the electricity generation in many regions of the world. This study presents a bibliometric analysis within the scope of "Geothermal Energy Utilization" (GEU). By determining the scientific development and bibliometric evaluation of the researched field, this study aims to identify the focal points of scientific studies and highlight development trends. By using VOSviewer, Bibliometrix (R), and Citespace software, an analysis was conducted on 7603 publications extracted from the Web of Science (WoS) Core Collection. The publications filtered according to the research topic were evaluated within the scope of publication number, country analysis, journal analysis, author analysis, keyword analysis and most influential publications analysis. According to the study results, the most productive country, journal and author were "China", "Geothermics" and "Ibrahim Dincer" respectively. According to the results of the thematic map analysis, the keywords "Organic Rankine cycle", "exergy" and "optimization" fall under the "motor" theme group.

Jeotermal Enerji Kullanımı Araştırmalarının Bibliyometrik Analizi

Abstract

İklim kriziyle mücadele ve iklim hedeflerinin ileriye taşınabilmesinde enerji kullanımı kilit faktördür. Enerji kaynaklarının etkin ve verimli kullanımı için teknolojik gelişimin yanı sıra bilimsel çalışmaların gelişen teknolojiyi desteklemesi oldukça önemlidir. Jeotermal enerji dünyanın birçok bölgesinde bulunan, elektrik enerjisi üretimi ve doğrudan kullanılabilen yenilenebilir ve doğal bir enerji kaynağıdır. Bu çalışmada "jeotermal enerji kullanımı" kapsamında bir bibliyometrik analiz sunulmuştur. Araştırılan alanın bilimsel gelişimi ve bibliyometrik değerlendirmesi belirlenerek, bilimsel çalışmaların odaklandığı konuların ortaya konulması ve gelişim eğilimlerine dikkat çekilmesi hedeflenmektedir. VOSviewer, Bibliometrix (R) ve Citespace yazılımları kullanılarak Web of Science Core Collection'dan çıkarılan 7603 yayın üzerinde analiz gerçekleştirilmiştir. Araştırma konusuna göre filtrelenen yayınlar yayın sayısı, ülke analizi, dergi analizi, yazar analizi, anahtar kelime analizi ve en etkili yayınlar analizi kapsamında değerlendirilmiştir. Çalışma sonuçlarına göre, en verimli ülke, dergi ve yazar sırasıyla China, Geothermics ve Ibrahim Dinçer olmuştur. Tematik harita analizi sonuçlarına göre, "Organik Rankine çevrimi", "ekserji" ve "optimizasyon" anahtar kelimeleri "motor" tema grubunda yer almaktadır.
