There has been a more significant trend from fossil fuels to renewable energy sources in recent years due to energy crises, environmental problems and sustainability. Renewable energy systems have become very useful and important especially photovoltaic and wind. This study focuses on a hybrid energy system. This hybrid system includes photovoltaic and wind energy systems as a renewable energy source. In addition, a diesel generator as a backup power source and battery storage system is used. The system is controlled with a fuzzy logic control (FLC) and optimizes energy distribution and maintains balance. A maximum power point tracking controller is developed using the perturb and observe algorithm and FLC. The photovoltaic and wind energy, has been analyzed weather conditions. The photovoltaic system produces about 3.5 kW. The wind turbine produces about 3.5 kW at 12 m/s wind speed. The diesel generator provides 5 kVA of backup power during periods of low renewable energy production. The 1000 Ah battery ensures energy balance and supports peak demand with 90% efficiency. The simulation results represent a 30% reduction in fuel consumption. In addition, this provides a 15% increase in system efficiency. The proposed approach effectively demonstrates the integration of renewable energy for sustainable power production. [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.

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]

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]

Newly industrializing economies are ardently striving for rapid development, aspiring to emulate the affluence of Western nations. However, amidst this relentless economic dynamism, the world grapples with an escalating climate change crisis. Therefore, it becomes imperative to identify the factors contributing to improving developing nations' environmental quality while concurrently advancing their sustainable development objectives. In this regard, the present study aims to dissect the environmental implications of renewable energy consumption, technological innovation, and human capital and examine the "Load Capacity Curve" (LCC) hypothesis in Türkiye through an extension of the STIRPAT model. To achieve this objective, the research operates a novel econometric methodology, namely the "augmented autoregressive distributed lag" (A-ARDL) approach with Fourier terms, to analyze yearly data from 1980 to 2019. The empirical findings substantiate the validation of the LCC hypothesis in Türkiye, both in the short and long term. Furthermore, the results unveil that renewable energy consumption and human capital significantly bolster ecological welfare over the long term, whereas technological innovation exhibits no discernible impact on the environment. Additionally, the outcomes display that population growth positively impacts the environment in the short term; nevertheless, over the long term, it becomes detrimental to environmental quality.

Today, water and wastewaters are effectively treated with many treatment technologies. However, there are deficiencies in the integration of treatment technologies with renewable energy sources. In this study, the integration of solar energy, one of the renewable energy sources, into electrooxidation (EO) process, which is one of the new generation advanced wastewater treatment techniques, is provided. Parameters affecting the EO process such as pH, current density (C.D.) and electrolysis time (E.T.) was optimized by Box Behnken Design (BBD) on elimination of soluble Chemical Oxygen Demand (sCOD) from metal processing wastewater. The study also tried to determine the optimum conditions for the treatment of metal processing wastewater with EO process by developing different scenarios. The scenario in which the energy requirement was 18.33 kWh/m³ and the COD removal efficiency was 75.23%, i.e. the scenario that maximizes the COD removal efficiency and minimizes the energy consumption (E.C.), is considered to be appropriate. In this case, the optimum pH for the EO process was 5, C.D. was 80 A/m², E.T. was 22.15 minutes with a desirability of 1. At the optimum conditions (for the 2nd scenario), the E.C. of the EO process was fulfilled from solar panel in a ratio of 15% and 318% in overcast and sunny weather, respectively. Thus, it has been determined that the solar panel integrated EO process is an approach that reduces E.C. and accordingly operating cost, and also has the potential to obtain enough energy to be stored especially in sunny weather.

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]

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]

A microgrid system has been designed and optimized via hybrid optimization of multiple energy resources (HOMER) software for the electricity needs of Eskisehir Osmangazi University (ESOGU). The microgrid consists of photovoltaic (PV) and wind turbine (WT) units with utility grid connection and battery energy storage system (BESS). The microgrid also supplies energy to electric vehicle (EV) charging units. The combination of EVs and renewable microgrids make a major contribution to the clean energy transition of the global energy system. It also minimizes the cost of energy (COE) and EV charging. Before analyzing the EV loads, a proper hybrid combination of the microgrid was optimized. The comparison and analysis of the proposed systems were performed according to their reliability, economic and environmental impact. The financial analysis of the winning microgrid system was carried out and its performance assessed throughout the duration of the project. Deferrable and on-demand EV charging modes were proposed in this study. To see the impact of EVs on the microgrid, various scenarios were created and applied to the design. The aim was to find a suitable charging method that uses mostly the renewable energy sources to minimize the cost of electricity while protecting the environment. This study demonstrates the importance of smart charging and how it manages charging sessions by leveraging renewable resources and charging only when electricity is at the lowest cost. The result also shows that the cost of the electricity bill of the investigated area is reduced by 36% by using the hybrid microgrid. [ABSTRACT FROM AUTHOR]

Apparel companies that corner the market, in line with their sustainability strategies, are looking for options that will cause the least harm to the environment, and life cycle analysis (LCA) approach is widely used for this purpose. The aim of this study is to determine the environmental effects of a hoodie with the LCA and to evaluate different alternatives for more sustainable production of this product. LCA studies were carried out with data obtained from the field of a factory that performs garment operations. The functional unit is a ready-toshipping hoodie, and first of all, the current environmental impacts of this product were determined with a cradle-to-gate approach. Then, the boundary of the gate-to-gate was used to determine the improvements that could be made only in the garment stage. Within the scope of the study, four scenarios were generated and the environmental effects of each scenario were compared with the current situation. Life cycle analyzes were performed with GaBi 6.0 LCA software. The selected impact category method is CML-2001. As a result of the evaluations, the best results were obtained with Scenario 5, which represents the use of biodiesel as a fuel type in transportation together with the use of renewable energy sources in all applications. With this scenario, reductions of 74.40%, 84.32% and 60.91% were determined in the effect categories of global warming, acidification and abiotic depletion, respectively, according to the current situation (Scenario 1).

Electrochemical wastewater treatment methods are effectively used for all type of wastewaters and pollutants. One of the huge negative impact of these processes is the energy consumption of the process. Therefore, the goal of the study is to develop a minimal energy user Electrocoagulation (EC) option with an integration of a direct photovoltaic solar panel as a subsection of electrochemical processes for the degradation of low COD (Chemical Oxygen Demand) from metal cutting wastewater. To optimize the operating parameters of the EC process such as pH, current density (C.D.) and electrolysis time (E.T.) Box-Behnken Design by RSM was used with a double criterial optimization option. COD removal and energy consumption were evaluated as responses of the model and they were well-fitted with the quadratic model. Also, it was determined that all parameters are effective on EC process. Optimum conditions were found at a pH of 7.48, a C.D. of 30 A/m², an E.T. of 65 min, an energy consumption of 3.9 kWh/m³ and a desirability of 0.954. At the optimum conditions, the energy consumption of the EC process was fulfilled from solar panel in a ratio of 71% and 1495% in overcast and sunny weather, respectively. Especially, the energy obtained by the solar panel in the sunny weather produces much more than the energy required of the process. [ABSTRACT FROM AUTHOR]

ÖZ: Ülke ekonomilerinde sürdürülebilir ekonomik büyüme ve kalkınma en önemli makroekonomik hedefler arasında yer almaktadır. Enerji ise ekonomik büyümenin gerçekleştirilmesi için en önemli girdiler arasında bulunmaktadır. Özellikle fosil yakıtlardan elde edilen enerji açısından kıt kaynaklara sahip olan Türkiye ekonomisinde, yenilenebilir enerji stratejik öneme sahiptir. İktisadi büyümenin çevre üzerindeki etkisi açısından karbon emisyonunun düşük olmasını sağlayan inovatif faaliyetler çevresel inovasyon olarak ifade edilmektedir. Bu çalışmada Türkiye ekonomisinde 1990-2018 örneklem döneminde çevresel inovasyon ile yenilenebilir enerji tüketimi ilişkisi incelenmektedir. Söz konusu ilişkinin incelendiği modele kontrol değişken olarak ekonomik büyüme ve doğrudan yabancı yatırım değişkenleri eklenmiştir. Modelde yer alan değişkenlerin birim kök süreci ADF birim kök testiyle incelenmiştir. Söz konusu değişkenler arasındaki uzun dönemli ilişki Pesaran vd. (2001) tarafından geliştirilmiş olan ARDL sınır testi ile araştırılmıştır. ARDL sınır testi bulguları eşbütünleşme ilişkisinin varlığını ortaya koymuştur. Eşbütünleşme katsayılarının tutarlılığını saptamak için hem ARDL hem de FMOLS ve CCR tahmincileri kullanılmıştır. Ampirik bulgular tüm tahmincilerde benzer sonuçları ortaya koymuştur. Bulgulara göre; çevresel inovasyon, ekonomik büyüme ve doğrudan yabancı yatırım değişkenlerinde meydana gelen artışlar, yenilenebilir enerji tüketimini azaltıcı etkiye sebep olmaktadır. ABSTRACT: Sustainable economic growth and development in national economies are among the most important macroeconomic targets. Energy is among the most important inputs for the realization of economic growth. Renewable energy has strategic importance especially in the Turkish economy, which has scarce resources in terms of energy obtained from fossil fuels. Innovative activities that ensure low carbon emissions in terms of the impact of economic growth on the environment are expressed as environmental innovation. In this study, the relationship between environmental innovation and renewable energy consumption in the 1990-2018 sample period in the Turkish economy is examined. Economic growth and foreign direct investment variables were added as control variables to the model in which the said relationship was examined. The unit root process of the variables in the model was examined with the ADF unit root test. The long-run relationship between these variables Pesaran et al. (2001) developed by ARDL bounds test. ARDL bounds test findings revealed the existence of a cointegration relationship. In order to determine the consistency of the cointegrating coefficients, both ARDL and FMOLS and CCR estimators were used. According to the findings; Increases in environmental innovation, economic growth and foreign direct investment variables cause a reduction in renewable energy consumption.

Antarctica is a continent that does not have a native population due to its climate characteristics and topographic conditions. Today, the current population on the continent consists of officials and researchers living in research stations established for scientific activities. More than 30 countries have conducted scientific studies with over 100 research stations in Antarctica. For the relevant stations to continue their activities, their energy needs must be met uninterruptedly. Even though the usage of renewable energy sources has recently increased in the relevant stations, most stations continue to produce their energy with fossil fuels. Countries carrying out their activities on this continent must protect Antarctica's ecosystem and natural and living resources. Fossil fuels release polluting gases into the environment and increase carbon emissions. In this context, it is necessary to examine the existing renewable energy potentials in the continent, and renewable energy facilities should be increased. First, this study is aimed to analyze the current renewable energy potential of 20 selected research stations in Antarctica. In the second stage of the study, a potential situation analysis was made regarding the use of renewable energy on Horseshoe Island, where the Turkish Research Station is planned to be established. Spatial analyses were conducted by comparing the MERRA-2 reanalysis data developed by NASA's Global Modeling and Assimilation Office (GMAO) with the data from the two existing research stations near Horseshoe Island. Thus, a preliminary study has been made on the renewable energy resources that the Antarctic Turkish Research Base can use. [ABSTRACT FROM AUTHOR]

Information about rainwater harvesting was given and its applicability in solar power plants was evaluated with scenarios. Rainwater harvesting is done on solar panels, and it is aimed at using the collected water for panel cleaning. For this purpose, the annual precipitation falling on the panel areas was calculated by choosing the solar power plant with the largest area in Turkey. As a result of the study, how much of the water consumption of the solar power plants can be met from rainwater was evaluated with 3 different scenarios. In the Base Scenario, the coverage rate for the amount of water required for cleaning is approximately 76% if cleaning is carried out daily. This rate drops to 59% in Scenario 1, 42% in Scenario 2 and 29% in Scenario 3. [ABSTRACT FROM AUTHOR]
