in the sector of electricity production, the existence of investment resources limitation and environmental factors are the main factors that influence this process. the reduction of costs and the destructive impacts of environmental have been always mentioned by specialists. consequently, the drasticality of the environmental protection and the electric-energy production lead to focus on solar...

Climate changes occur on all time scales, as illustrated in Figure 2-1 by the trend of global mean surface air temperature in the past century, the past millennium, and the past 30,000 years. The range of global mean temperature in the past 30,000 years and indeed the past million years has been of the order of 5C. At the peak of the last glacial period, the Wisconsin ice age approximately 18,0...

this paper estimates the trend of total energy subsidies from year 2003 (that is 16.68% of gdp) and running a model, predicts that energy subsidies will reach to 20% of gdp by 2019 if subsidies continue. also environmental damage costs of energy consumption have been entered the model (environmental cost-benefit analysis model: ecba model) in addition to the vast amounts of subsidies. so damage...

Abstract Rising emissions of anthropogenic greenhouse gases (GHG) have led to tropospheric warming and stratospheric cooling over recent decades. As a thermodynamic consequence, the troposphere has expanded rise tropopause, boundary between stratosphere, been suggested as one most robust fingerprints climate change. Conversely, at altitudes above ∼55 km (in mesosphere thermosphere) observationa...

The global demand for clean energy is growing, as the World looking ways to compensate Green House Gases (GHG) emissions and fight warming through what being called transition. In this context, present article has its guiding question: can solar panels be used radioactive sources generation? objective of study was explore potential usage with sources, a cogeneration systems. This documental lit...
