Abstract:Energy is one of the most important factors affecting the country's economy in developing countries. Factors such as interdependent relations, external dependence in primary energy sources such as natural gas and oil, international treaties to reduce carbon emissions, and the amount and availability of domestic conventional resources lead countries to renewable energy sources. In this study, the production sources and sectoral consumption places of the electric energy in Ankara in 2019 were examined. In additi… Show more
“…In the modern world, fossil fuels are used as the main and most common source to meet energy needs in every field [1]. Due to the negative environmental effects, high costs, and limited resources of fossil fuels, it has become necessary to search for more environmentally friendly, inexpensive, and easily obtainable energy sources [2].…”
Renewable energy sources are becoming very important in today’s World. Thermovoltaic power sources are getting cheaper and their electrical power output is getting higher due to technological developments. New, application areas of thermovoltaic power sources are being looked for. Samovars are pretty commonly used in rural areas to prepare warm drinks such as tea. They burn brushwood. Samovars only supply thermal power. Integrating a thermovoltaic power source onto a samovar would increase their overall electrical energy. Such a system may allow charging batteries of low power loads such as flashlights and cell phones. In this study, the performance of such a system is experimentally inspected. It has been found that the system power is low, the air convection around the semiconductor pairs of the module may be contributing to its low power performance, and a more complex system model is needed to model it accurately.

Enerji, ekonomik, endüstriyel ve toplumsal kalkınma için hayati öneme sahiptir. Enerji tüketimindeki artış istikrarlı bir şekilde artmaktadır. Sera gazı emisyonlarına, hava, su ve toprak kirliliğine neden olan fosil kökenli yakıtların yerini sürdürülebilir ve çevre dostu yenilenebilir enerji kaynakları almaktadır. Yenilenebilir enerji kaynaklarının temelini oluşturan güneş enerjisi, hem elektrik enerjisi üretiminde hem de termal enerji üretiminde kullanılabilmektedir. Bu çalışmada güneş enerjisi uygulamaları ile Ankara ili iklim şartlarında, iki kişilik bir evin elektrik ve ısınma ihtiyacının karşılanması incelenmiş, çevresel analizi yapılmıştır. Çalışmada fotovoltaik paneller, vakum tüplü U-borulu güneş kolektörü ve fotovoltaik termal panellerin ayrı ayrı ve birlikte kullanımı ile elde edilecek enerji miktarı hesaplanmıştır. Ayrıca fotovoltaik termal panellerde çalışma akışkanı olarak su ile birlikte Al2O3+CuO hibrit nanoakışkanı da kullanılarak, nanoakışkan kullanımının termal enerji transferine etkisi de araştırılmıştır. Çalışma sonucunda, sadece fotovoltaik panel kullanımı ile enerji ihtiyacının karşılanması için 11 adet 325 W gücünde panele, sadece fotovoltaik termal panel kullanımı ile karşılanması durumunda ise 7 adet 300 W elektrik, 600 W termal güce sahip panel gerektirdiği hesaplanmıştır. Ayrıca fotovoltaik termal sistemde Al2O3-CuO hibrit nanoakışkanının saf su yerine kullanılması ile verimde %19.41 oranında artış sağladığı görülmüştür. Enerji ihtiyacını karşılamak için güneş enerjisi kullanımının dünyada artan doğal gaz sorununa hem yerli enerji kaynağı kullanılarak ekonomiye hem de sera gazı emisyonlarını azaltarak çevresel çözüm olacağı önerilmektedir.
