This study aims to explain the reasons behind the recent energy problems, contradictions, and divergences among the members of the European Union (EU), the global leader of the green energy transition and green norms. The interruption of energy supply in Europe due to geopolitical tensions and conflicts, and the contradictions and problems related to the green energy transition process erode and change the green norms of EU energy policy and make economic interest-oriented approaches visible. EU energy policy, which is based on green transformation planning without undermining production and competitiveness by ensuring security of supply within the framework of balanced relations with Russia, is now facing a paradigmatic shift in which security of supply is jeopardized, and problems related to renewable energy are decisive. The article argues that this paradigm shift underlies the contradictions in the construction of the EU's common energy policy and the divisions among members on fossil fuels and nuclear energy. Hence, it argues that EU energy policy is no longer as green as it seems. [ABSTRACT FROM AUTHOR]

This study aims to examine the dynamic relationship between carbon dioxide (CO2) emissions, renewable energy consumption, and economic growth in Denmark, Sweden, and Chile. These countries were not randomly selected. They were chosen since they have the highest scores according to the Climate Change Performance Index (2023). In addition, Markov-switching vector autoregressive (MS-VAR) and Markov-switching Granger (MS-Granger) causality methods are applied to the annual data of the three countries over the period 1971–2021. Contrary to linear methods, MS-VAR and MS-Granger causality approaches allow us to estimate and interpret this relationship for different regimes, such as recession and expansion. These methods also provide insights into the likelihood and duration of the persistence of the current economic regime. The empirical results show that there is a two-way MS-Granger causality between renewable energy consumption and economic growth in all regimes for the three countries except for moderate and high expansion regimes for Chile. Moreover, in general, there is a two-way MS-Granger causality between economic growth and CO2 emissions in all regimes. Furthermore, the findings from the estimated models indicate that there is a two-way MS-Granger causality between renewable energy consumption and CO2 emissions in general, except for the second regime for Chile.

Dünyada ve ülkemizde artan nüfus hızıyla birlikte çevre kirliliği problemleri ön plana çıkmış ve iklim değişikliğine sebep olacak boyutlara ulaşmıştır. Bu durum ülkeleri ekonomik ve sosyal bazı dönüşümlere zorlamaktadır. Her birey iklim değişikliği ile mücadelede sorumluluk sahibi olmalıdır. Pek çok kültürde toplumun temel direği olarak kabul edilen kadınların bu konudaki rolleri çok önemlidir. Özellikle kadınlar doğal kaynaklara zarar verici yaşamsal faaliyetlerden uzak durmaya eğilimli oluşlarıyla, doğaları gereği çevre dostu kabul edilebilirler. Günümüz koşullarında kadınların iklim değişikliği ile mücadelede daha etkin rol alması gereksiniminden hareketle öncelikli olarak kırsalda yaşayan ve tarımsal faaliyetlerle ailesine katkıda bulunan kadının konvansiyonel yanında yenilenebilir enerji kaynaklarını da kullanabiliyor olması gereklidir. Ülkemizde oldukça yüksek potansiyele ve katma değere sahip hayvansal ve bitkisel atıkların kadınların öncülüğünde öncelikle aile içi küçük işletmelerde sonrasında özellikle kadın kooperatifleri aracılığıyla daha geniş kitlelere ulaşarak biyogaza dönüştürülmesiyle tarımın sürdürülebilirliğine ve ekonomiye olumlu etkiler sağlanması hedeflenmelidir.

In this study, a metaheuristic Particle Swarm Optimization based optimization tool has been designed to be used in the optimization of Hybrid Renewable Energy Systems, which eliminates the negative aspects of the most frequently used HOMER software in this field. In the comparison made in terms of processing speed, it was seen that the designed system reached the result faster by obtaining the result in 17 seconds, which the HOMER software obtained in 936 seconds in optimizing the same system. In the economic comparison, as a result of the optimization made by two different tools; There is a difference of 1.737% in Energy cost, 0.85% in Total Net Present Cost and 1.895% in Initial Capital, and there is no significant difference between the results. In the comparison of the electrical results, there is a difference of 0.031% for the fed loads and 1.071% for the unmet loads, and the reliability of the results in electrical terms has been demonstrated. The capacity shortage parameter was used for the first time in the optimization of renewable energy sources with the metaheuristic algorithm. Energy Cost is used as the objective function. In short, a unique and reliable optimization tool has been designed as an alternative to the HOMER program that can achieve much faster results and eliminates the sensitivity, cumbersomeness and difficult search space generation processes in the HOMER program. This tool will also facilitate the generation of a large amount of data by obtaining the necessary optimization outputs very quickly to train surrogate models, machine learning or deep learning based optimization systems.

Recently, the rapid advancement of technology and the fast-growing population have led to an increase in the demand for energy. Each country requires continuous, sufficient, and clean and green energy resources to grow its economy and improve living standards. Moreover, a country's energy resources are also an indicator of its competitiveness on the global stage. In recent years, Türkiye has been among the countries that have been making efforts and investments in energy production by utilizing its own resources. Particularly, due to the geographical advantages, the establishment of solar power plants has accelerated, while hydroelectric power plants, both with and without dams, are being used to generate electricity from water power. The aim of this study is to evaluate the outcomes of the investments made in Turkey in recent years in terms of the potential and usage of renewable energy sources, specifically hydroelectric and solar energy, and to analyze and compare developments in these fields. Additionally, all the data used in this study have been analyzed separately on both regional and provincial levels in Türkiye, and the results are presented accordingly. [ABSTRACT FROM AUTHOR]

Global environmental problems have increased in recent years and have become a problem requiring urgent action. The energy sector is responsible for most of the pollution produced. However, it holds the key to mitigating these challenges through low-carbon energy solutions. The importance of transitioning to energy sources with low carbon emissions, such as renewable and nuclear energy, has gained momentum in recent years. Energy taxes and energy-related research and development (R&D) spending can play an important role in shaping low-carbon energy consumption. Governments can influence the adoption of low-carbon energy by taxing carbon-intensive fuels and encouraging investments in clean energy technologies. Additionally, public spending on R&D facilitates innovation and technological advances in the energy sector, thereby increasing the viability and competitiveness of low-carbon energy solutions. From this point of view, this study investigates the impact of public energy expenditures and energy taxes on low-carbon energy in the 10 nations with the highest clean energy use from 1994 to 2021 with DCCE and CCE estimators. According to the results, energy taxes and energy expenditures encourage low-carbon energy consumption in Finland. Government energy expenditures in Norway and Switzerland and energy taxes in Austria negatively affect low-carbon energy consumption. These findings underscore the need for governments to implement comprehensive policies that effectively encourage investment in low-carbon energy technologies, enabling sustainable and environmentally friendly energy transitions on a global scale. Joint efforts of governments and private sectors are crucial to ensure a greener future for future generations. [ABSTRACT FROM AUTHOR]

This study utilized data from the World Bank, the Organization for Economic Cooperation and Development (OECD) and Eurostat to examine various aspects of innovation processes such as the development of new products in sustainable economic policies, patent acquisition, investments in environmental economics, and the advancement of environmentally focused technologies. The analysis covered both EU countries and Türkiye. Specifically, data on CO2 emissions, Gross Domestic Product (GDP), renewable energy consumption, foreign direct investments, industrial production, and urban population were used. The findings reveal significant diversity in innovation trends across EU member states. Time series data from EU countries were averaged and compared with those from Türkiye. The analysis of EU member state data indicates an increasing trend toward innovations that address environmental and societal concerns. To ensure a more sustainable future for coming generations, greater attention must be given to the conservation of valuable but limited resources-such as green spaces, environmental protection, and natural resources-while closely adhering to sustainability strategies and plans. Successful innovation processes require a focus on several key factors, including human capital quality, technological infrastructure, knowledge dissemination, financial resources, and sustainable policy frameworks. The research is based on data from 2000 to 2020 on CO2 emissions, GDP, renewable energy consumption, foreign direct investments, industrial production, and urban population. A unit root test was performed to determine the stationarity of the data, and Granger causality analysis was employed to assess the relationships among these variables. [ABSTRACT FROM AUTHOR]

With the increase in climate change, environmental pollution and emissions in the world, a fight with fossil fuels has been entered. Many countries have begun to take measures to control CO2 emissions, enact laws and amend existing laws. Traditional logistics, which ignores the deterioration of ecological balance, adopts only product and consumption-oriented logistics. Issues such as waste management, the use of renewable energy sources and the circular economy are neglected. While traditional logistics is a purely cost-oriented and monetary-oriented type of transportation, green logistics concept has been revealed as an alternative to this situation. Especially in the emergence of green logistics, the increase in sensitivity and concerns about the environment can be shown as a reason. With the development of the logistics sector, the trend has started to increase in issues such as ecological balance, emission emission emission rates, savings understanding and renewable energy sources. In this context, many companies operating in the logistics sector use efficient transportation methods compatible with the environment, development of distribution and packaging systems, and, he decided that many services such as waste management and emission control should be within the framework of a nature-friendly understanding. These eco-friendly practices have accelerated the transition from traditional logistics to green logistics understanding, enabling companies to update their mission and vision policies. Because the issue to be considered here is the continuous reduction of the supply of natural resources globally and the increase in the degree of pollution. Green logistics activities, which also contribute to the circular economy, are the most important factors that enable the development of a sustainable environment. With renewable energy policies becoming an important issue in the field of logistics, environmentally friendly practices have emerged. In particular, companies within the scope of green logistics in order to achieve maximum profit at minimum cost; green supply, green production, green packaging, green transportation, green storage and on the contrary, logistics have begun to focus on issues such as. Because companies need to discover new markets and improve their brand image in order to have a good position in international markets. Carrying out both production and logistics activities without leaving waste in nature will ensure the efficient use of company resources and increase the company's preferability in international markets. Today, with the increase of environmental destruction, countries have started to bring a green-oriented understanding of their strategic plans and policies. Thanks to the sustainability of the energy resources used, having a lower carbon footprint is important for future generations. In Turkey, it can be said that this understanding has just begun to be applied and that it should produce a policy in a more conscious way. With the introduction of alternative energy sources in Turkey, it is also ensured that the foreign trade deficit of the energy-dependent country is reduced. The country's seasonal availability has expanded its range of uses, making it easier to discover, develop, promote and use renewable energy sources. In addition, the sensitivity of consumers in this regard has started to increase. In this study, renewable energy sources and green logistics relationship were examined in Turkey and Johansen cointegration test and Toda-Yamamoto causality analysis were performed for the period 1990-2019. Johansen cointegration analysis results show a long-term cointegration relationship between variables. In the Toda-Yamamoto causality test applied, a one-way causality relationship has been determined from gross domestic product to the amount of CO2 emissions from the logistics sector. This causality relationship states that economic growth is a variable that affects the amount of carbon emissions. This study also reveals that renewable energy sources should be used in a wider area. Analyzing how it is applied to other sectors, the stages to be followed and its contribution to the economies of the country can be an inspiration for future studies. [ABSTRACT FROM AUTHOR]

Developing technology and increasing population trigger the increasing of the energy demand. As a result, increase in energy demand has accelerated the studies in this field. Conventional energy sources were used currently as usual however it was desired to be limited due to the risk of depletion and negative environmental effects. Therefore, environmentally friendly and no risk of depletion renewable energy sources have created an alternative to conventional energy sources were the frequently studied topics recently. The use of biomass as a renewable energy source has led to development in agriculture and animal husbandry. Products that appear as waste in agriculture and animal husbandry will be evaluated and recycled. If animal feces remain in nature, the methane gas released creates a greenhouse effect and causes global warming. It becomes harmful to human health after mixing with water. For this reason, it is important to obtain electrical and heat energy and dispose of it recyclable. Within the scope of this study, the potential electrical energy that can be obtained from biogas was investigated, considering the collectability of animal feces in Ankara, Gaziantep and Kars provinces located in different regions of our country. In this context, it has been determined that 375,497.55 Mega Watt Hour Electricity (MWhe/year ) from Ankara, 115,452.27 MWhe/year from Gaziantep, and 198,691.4 MWhe/year from Kars have the potential to obtain electrical energy from biogas.

Due to the harmful effects of traditional energy sources on the environment and health, the consumption of renewable energy sources has recently come to the fore on the world agenda. In order for national economies to maintain their existence, individuals must ensure their health and welfare. In this context, the priority duty of countries should be to protect public health and ensure its sustainability. There are many factors that determine a country's level of healthcare expenditures; environmental conditions are also one of them. The increase in greenhouse gas emissions resulting from the consumption of non-renewable energy sources can pose a great danger to human welfare and the environment. Environmental problems caused by greenhouse gas emissions negatively affect human health in many ways, such as affecting the nervous system, lungs, and causing respiratory diseases. In addition, environmental pollution resulting from greenhouse gas emissions increases health expenditures and causes a decrease in labor productivity. Considering these negative effects, increasing the use of wind, solar, geothermal, and other environmentally friendly energy sources, which are renewable energy sources, will contribute to environmental improvement by meeting the energy needs of countries. Recently, the increase in the resources allocated to health expenditures from the national income of countries has made the discussion of sustainability in the relevant field a current issue. In this respect, researching the factors affecting health expenditures will provide important information to policy makers. This study examines the health expenditures of renewable energy consumption in 13 EU countries (Belgium, Czech Republic, Denmark, Germany, Austria, Spain, Sweden, Italy, Portugal, Greece, Finland, France, and the Netherlands) selected considering data availability between 2000 and 2020 investigating in which direction it affects. In the study, countries with the highest consumption of renewable energy were selected. Since the sustainability of the recently increasing health expenditures is important, the variables of renewable energy consumption and economic growth were analyzed and the subject was limited. In this context, it is believed that the findings will provide important information to policy makers. The main motivation of the study is that there are limited studies on the relevant subject in the literature and panel cointegration and panel cointegration coefficient estimator tests are not used. Obtaining renewable energy consumption and health expenditure data from 2000 to 2020 constitutes the main limitation of the study. As analysis methods, Lagrange multiplier (LM) cointegration and Common Corelated Effect (CCE) cointegration estimator tests were used. Before the application of these tests, cross-sectional dependence and homogeneity were determined. Fourier LM unit root test was used in examining the unit root process. Then, cointegration test and cointegration coefficient estimators, which is the last stage of the application, were determined. According to the panel cointegration coefficient estimation results, in the general analysis conducted for 13 EU countries, the effect of renewable energy consumption on health expenditures is statistically significant at the 10% level. Accordingly, a 1% increase in renewable energy consumption decreases health expenditures by 0.197%. In country-specific studies, the effect of renewable energy consumption on health expenditures was statistically significant and negative in Denmark, Spain, Sweden, and Greece, reducing health expenditures by 0.132%, 0.111%, 1.288%, and 0.782%, respectively. The effect of GDP on health expenditures appears to be statistically significant at the 1% level. Accordingly, a 1% increase in income increases health expenses by 1.071%. In country-based analyses, the coefficients are statistically significant and positive in Germany, Austria, Belgium, Czech Republic, France, Spain, Sweden, Italy, Portugal, and Greece. These findings indicate that the increase in environmentally friendly, reusable energy consumption will have a positive impact on the environment, reduce health expenditures and contribute positively to the sustainability of health financing. In addition, it emphasizes that increases in GDP are reflected in health expenditures, thus increasing the quality of health. [ABSTRACT FROM AUTHOR]

This review includes the concept of green energy, important incentives that can accelerate investment processes, and factors affecting the transition from fossil fuel-based energy to renewable resources. Transition factors to green energy affect many behaviors towards energy, as well as the acceptance of different energy policies and energy system changes. Green energy and sustainability of energy requires a comprehensive transformation of economic structures, technologies and institutions. The role of social sciences in engaging consumers in sustainable energy behaviors, supporting the adoption of new technologies, and encouraging policy changes in energy systems should not be overlooked. The promotion of renewable energy relates to three main positive aspects of green energy. These are consequences on the environment, consequences on the level of development of the country and social pressure. Developing efficient energy conversion systems that do not have low environmental impact and recommended policies for the expansion of renewable energies are some of the recent progress in limiting greenhouse gas emissions and sequestering CO2. In this article, the theoretical and practical foundations of green energy incentives in Türkiye are analyzed together with the factors affecting them. Additionally, reviews of the diversity of energy incentives and their effectiveness and efficiency are presented.

Bu çalışma, Bursa ilinde üç farklı devlet okulunda öğrenim görmekte olan 813 ortaokul öğrencisinin yenilenebilir enerji kullanımına yönelik niyetlerini planlanmış davranış teorisi çerçevesinde derinlemesine incelemeyi hedeflemektedir. Araştırmada, tutum, öznel norm, algılanan davranış kontrolü ve niyet bileşenlerinden oluşan bir model önerilmiş ve bu modelin geçerliliği yapısal eşitlik modellemesi kullanılarak test edilmiştir. Yenilenebilir enerji kullanımına yönelik niyeti ölçmek amacıyla çok boyutlu bir 'Yenilenebilir Enerji Kullanımına Yönelik Niyet Ölçeği' tasarlanmış ve bu ölçeğin geçerliliği doğrulayıcı faktör analizi ile test edilmiştir. Analiz sonuçları, tasarlanan ölçeğin yüksek geçerlilik ve güvenirlik katsayılarına sahip olduğunu göstermektedir. Önerilen modelin bileşenleri arasındaki ilişkileri incelemek için yapısal eşitlik modellemesi teknikleri kullanılmıştır. Bulgular, öğrencilerin yenilenebilir enerji kullanımına yönelik tutum ve algılanan davranış kontrolü değişkenlerinin niyeti pozitif bir şekilde yordadığını göstermektedir. Ancak, bu modelin bir diğer kritik bileşeni olan öznel normların, yenilenebilir enerji kullanımına yönelik niyet üzerinde anlamlı bir etkisinin olmadığını ortaya koymaktadır. Bu sonuçlar, özellikle ortaokul öğrenci popülasyonuna özgü bir sosyal ve kültürel bağlamda, planlanmış davranış teorisi bileşenlerinin farklı bir etki profili sergileyebileceğini işaret etmektedir. Sonuçlar göz önüne alınarak farklı faktörlerin etkisini daha kapsamlı bir şekilde değerlendirmek için etik inançlar, bilgi seviyesi, faklı coğrafik bölgelere ve sosyoekonomik durum gibi değişkenler de araştırmalara dâhil edilerek benzer araştırmaların yapılması önerilebilir.

Bu makalede çevresel bozulma ile ekonomik büyüme, yenilenebilir enerji tüketimi ve enerji yoksulluğu arasındaki etkileşim araştırılmıştır. Çalışmada 47 Afrika ülkesine ait 2000-2019 yıllarını kapsayan veriler kullanılmıştır. Çevresel bozulma göstergesi olarak CO2, ekonomik büyüme göstergesi olarak kişi başına GSYH, yenilenebilir enerji göstergesi olarak toplam nihai enerji tüketimi içindeki yenilenebilir enerji oranı ve enerji yoksulluğu göstergesi olarak pişirme için hane halklarının temiz enerjiye erişim oranı verileri ile elektrik enerjisine erişim oranı kullanılmıştır. Çalışmada yenilenebilir enerji tüketim oranının ve enerji yoksulluğunun çevre üzerindeki etkilerinin incelenmesi amaçlanmıştır. Uygulanan kantil regresyon analizi sonuçlarına göre yenilenebilir enerji kullanım oranındaki artışlar çevre kalitesi üzerinde iyileştirici bir etkiye sahipken ekonomik büyüme ve enerji yoksulluğu değişkenlerinin çevre kalitesi üzerinde negatif bir etki oluşturduğu bulunmuştur.

Bireylerin hayatlarını sürdürebilmelerinde ve işletmelerin de mal ve hizmet üretebilmelerinde enerji kullanımına ihtiyaç vardır. Enerji, genel olarak yenilenebilir ve tükenir enerji olmak üzere iki kategoride ele alınmaktadır. Günümüzde petrol ve gaz gibi sınırlı bir kaynak olan ve yenilenemeyen enerji kullanımı birçok alanda yaygın olarak kullanılmaya devam etmektedir. Bundan dolayı alternatif enerji kaynaklarının yaygınlaştırılmasındaki yüksek finansal bütçe dikkate alındığında ve ülkelerin sahip oldukları kaynaklarını verimli bir şekilde kullanmasında finans sektörü önemli bir rol oynamaktadır. Etkin bir finans sektörü ile daha düşük oranda kredi temini, kaynakların ve enerjinin tasarruflu kullanımı, risklerin yönetilmesi ve işletmelerin üretim süreçlerinde çevre dostu teknikleri kullanması gibi birçok alanda gelişim kaydedilebilmektedir. Enerji tüketimini azaltma hedefi ve alternatif enerji kaynaklarının kullanımında yüksek sermaye yatırımı ihtiyacı nedeniyle yenilenebilir enerji kaynaklarında geleneksel enerji kaynaklarına göre daha fazla sermaye kullanımı görülmektedir. Yenilenebilir enerji bir ülkenin petrol ve gaz gibi ithal enerji ürünlerine olan bağımlılığını azaltmada önemli rol oynayabilmektedir. Dolayısıyla yenilenebilir enerji yatırım projelerinin geliştirilmesi ve yaygınlaştırılmasında borç ve sermaye finansmanını kolaylaştırmak için güçlü bir finansal yapıya ihtiyaç vardır. Bu bağlamda, finansal sektörün önemli bir bileşenini oluşturan katılım finans sektörü de iklim finansmanı çerçevesinde özellikle yenilenebilir enerji, iklime dayalı tarım, kentleşme, su ve ulaşım gibi alanlarda yeşil yatırım finansmanına giderek daha fazla önem vermektedir. İslami Finans Gelişim Raporu’na göre küresel katılım finans varlıkları 2021 yılında 3.9 trilyon dolar olarak gerçekleşirken 2026’da 5.9 trilyon dolara yükseleceği tahmin edilmektedir. Bu bilgiler çerçevesinde, çalışmada katılım finans alanında önde gelen ve ampirik çalışma için analiz verilerine erişilebilen Birleşik Arap Emirlikleri, Endonezya, Kuveyt, Suudi Arabistan ve Türkiye örneklemi üzerinde katılım finans gelişimi ile enerji tüketimi ve yenilenebilir enerji etkileşiminin ortaya koyulması amaçlanmıştır. Analiz edilen ülkeler belirlenirken İslami Finansal Hizmetler Kurulu tarafından yayımlanan İslami Finansal Hizmetler Endüstrisi İstikrar Raporu referans alınmıştır. Çalışmanın temel amacı doğrultusunda üç adet panel veri modeli kurulmuştur. Modellerde enerji tüketimi, karbon emisyonu ve yenilenebilir enerji kullanımı bağımlı değişkenler olarak kullanılırken katılım finans gelişimi ve kişi başı gayri safi yurtiçi hasıla bağımsız değişkenler olarak analiz edilmiştir. Katılım finans gelişimi göstergesi olarak analiz edilen ülkelerdeki katılım finansa erişim, toplam katılım finans varlıkları ve likit varlıklar ele alınmıştır. Ampirik çalışmadaki değişkenlere ait veriler, 2013-2019 periyodundaki yıllık verilerden oluşmaktadır. Panel veri analizi kapsamında öncelikle varsayımlar test edilmiş ve ardından havuzlanmış modelin tahmin edilmesine yönelik Breush-Pagan testi yapılmıştır. Bu testin ardından modelin havuzlanamayacağı ve sabit etkiler ile rassal etkiler modelleri arasındaki seçim için Hausman testi uygulanmıştır. Araştırma modelleri için yapılan panel veri analizi sonucunda enerji tüketimi ile katılım finans varlıkları arasında pozitif yönlü ilişki tespit edilirken katılım finansa erişim ile enerji tüketimi arasında negatif yönlü bir ilişki saptanmıştır. Öte yandan yenilenebilir enerji kaynaklarının kullanımı ile katılım finans varlıkları arasında pozitif yönlü ilişki belirlenirken, katılım finansa erişim ile yenilenebilir enerji arasında istatistiksel olarak negatif yönlü bir ilişki ortaya koyulmuştur. Başka bir ifade ile analiz edilen ülkelerdeki katılım finans varlıkları ve katılım finansa erişim enerji tüketimini istatistiksel olarak etkilemektedir. Sonuç olarak elde edilen bulgular, katılım finansman kaynaklarının çevresel yatırım alanları için daha kolay erişilebilir olmasına işaret etmektedir. Ayrıca bulgular, katılım finansman ile enerji verimliliğini arttıran ve enerji tüketimini azaltan alternatif enerji kaynaklarına daha fazla ağırlık veren politikaların geliştirilmesi gerekliliğine işaret etmektedir.

The Autoregressive Distributed Lag (ARDL) bounds test approach is used in this study to provide empirical evidence about the impact of renewable energy usage, exchange rate, and inflation rate on agricultural sector employment in Turkey from 1990 to 2019. According to the study’s findings, a 1% increase in renewable energy usage will raise agricultural sector employment by 1.06% in the short run, a 1% inflation will reduce agricultural sector employment by 0.12%, and a 1% Turkish Lira appreciation will raise agricultural sector employment by 0.4%. The long-run ARDL model results show a 1.06% decrease in agricultural sector employment for every 1% increase in renewable energy use, whereas inflation shows a 0.09% decrease in agricultural employment for every 1% inflation rate, while every 1% Turkish Lira appreciation increases agricultural employment by 0.08%. Based on these study findings, renewable energy promotes agricultural employment in the short run. In the meantime, long-term renewable energy development cannot accommodate agricultural sector employment. As a result, Turkey must devise a long-term renewable energy development strategy that will increase employment while keeping inflation and exchange rates stable and not harming agricultural employment.

Today, efforts to expand renewable energy sources, which can be an alternative to fossil fuels, are increasing due to both the damage they cause to the environment and the limited resources. More efficient use of energy resources in our country will reduce Turkey's dependence on fossil energy resources and provide sustainable and environmentally friendly energy for future generations. One of the sustainable and environmentally friendly energy types is biogas. Agricultural and animal wastes have an important place among the organic wastes to be used in the production of biogas. In this study, the biogas production potential with ovine manure and poultry manure in Aksaray province was investigated. According to the research findings, the biogas potential to be obtained from ovine and poultry manure in Aksaray province is 39 670 717 m3/year in total. This amount is equivalent to 186 452 372 kWh electrical energy. It has been determined that the energy needs of 12% of the population of Aksaray can be met with the electrical energy that can be obtained. The research findings are expected to raise awareness and guide both researchers and policy makers. [ABSTRACT FROM AUTHOR]
