Renewable energy, which is the type of energy that plays a major role in development and growth countries, an important today’s world, considering life depleted resources finite. Compared to fossil sources, except its source infinite, noticeable difference carbon dioxide emission seen as reason for preferring renewable sources. Many studies literature investigate relationship between consumptio...
this paper, examines the factors that influence energy intensity- the ratio of energy consumption to gdp- in 42 oil exporting and none-oil exporting countries in the period 1985 to 2009. the research applies panel data models to analyze the impacts of oil price, gdp, exchange rate, co2 emissions, population, surface area and productivity on energy intensity. an attempt is made in this paper, to...
Apart from being the most urbanized and largest emitter of CO2 emissions in Africa, South Africa currently harbours an ecological deficit territory mainly due to its desire attain more growth with less attention natural environment. Since environmental distortions are outcome human activities, this study becomes first investigate linkage between resource (NR), capital, energy consumption, footp...
مسائل زیست محیطی به خصوص تغییرات آب و هوایی به دلیل افزایش گازهای گلخانه ای در چند دهه اخیر مسئله ای جهانی شده است. انتشار co2 مهمترین عامل در افزایش گازهای گلخانه ای می باشد. آمار موجود در ایران نشان می دهد که سرانه انتشار co2 از607 کیلوگرم در سال1346 به 7/4977 کیلوگرم در سال1382 و7/6881 کیلوگرم در سال 1386 رسیده است که بیش از11 برابر شده است. هزینه های اجتماعی تخریب محیط زیست در اثر مصرف حامل...
In recent years, fossil energy consumption has increased because of economic growth and this has led to carbon dioxide emissions and environmental crises. Governments struggle to solve this problem by appropriate policies such as green or environmental tax policies. This policy is based on costs and can control pollution and increase renewable energy consumption as a substitute for fossil ener...
Electricity waste is a bottleneck in availing clean, green, uninterrupted, and sustainable electricity supply. The synthesis of the studied literature portrays that irresponsible behavior indulges consumers to take action, which leads crisis. Therefore, get know-how behavior, this study aims investigate role awareness concerning consumption, wastage, gadget efficiency, conservation. A questionn...

We analyze various regulatory regimes for electricity transmission investment in the context of a transformation of the power system towards renewable energy. We study distinctive developments of the generation mix with different implications on network congestion, assuming that a shift from conventional power plants towards renewables may go along with exogenous shocks on transmission requirem...
This study aims to investigate the determinants of capital structure (CS), how they differ among levels (upstream, midstream, and downstream), identify Which CS theory is more relevant oil gas companies in GCC. It uses secondary data 22 listed GCC over ten years (2010 2019). The will add literature as there few studies about petroleum industry it only sector. Using pooled ordinary least square ...
