Hydrogen is readily obtained from renewable and non-renewable resources via water splitting by using thermal, electrical, photonic and biochemical energy. The major hydrogen production is generated from thermal energy through steam reforming/gasification of fossil fuel. As the commonly used non-renewable resources will be depleted in the long run, there is great demand to utilize renewable ener...
the aims of this study were to assess the energy and economic flows of biodiesel production from olive pomace oil using transesterification method with ultrasound waves. for this purpose biodiesel production from this feedstock were examined through a life-cycle process with considering five main stages of agricultural production, transportation, olive oil extraction, pomace oil extraction and ...
One of the country's issues in the renewable energy sector for sustainable development is their financing. The current research was carried out with the aim of deeply understanding the dimensions, components and indicators of renewable energy financing and explaining the causal relationships between them in order to design a suitable model using a mixed (qualitative-quantitative) approach. In t...
We develop a spatial model of energy exploitation where energy sources are differentiated by their geographic location and energy density. The spatial setting creates a scaling law that magnifies the importance of differences across energy sources. As a result, renewable sources twice as dense, provide eight times the supply; and all new non-renewable resource plays must first boom and then bus...
using photovoltaic systems is gradually expanded by increasing energy demand. abundance and availability of this energy, has turned to one of the most important sources of renewable energy. unfortunately, photovoltaic systems have two big problems: first, those have very low energy conversion efficiency (in act between 12 and 42 percent under certain circumstances). second, the power produced b...
In this paper, we use the insights of the Real Business Cycles School, to calculate effects of different approaches to allocation of non-renewable (oil) resources’ revenues on Iran’s economic growth. We compare three different approaches, namely allocating the total revenue to the government, allocating some part of the revenue to the government and the rest to investing and allocating the reve...
The displacement of non-renewable fossil fuels by renewable energy resources has occurred at a low rate in the USA. But a large number of drivers is expected to cause significant expansion of the US renewable energy industry in the near future. Included among the extrinsic drivers, or those that are not directly related to renewable energy resources, are reductions in natural gas and crude oil ...
Analysis of effecting renewable energy consumption on environment according to role of human capital
The limitation of non-renewable resources and the increasing of environmental pollution caused by the accumulative consumption of fossil fuels indicate the necessity of paying attention to renewable sources. The present study analyzes the factors affecting on the quality of the environment with emphasis on the consumption of renewable energy and human capital such as education in developing and...
Today, renewable energy source of power generation has become very promising. As we know that conventional or non-renewable source of energies are very limited and are depleting very rapidly. Increasing energy needs of the world and continually growing population there is a power demand gap and it needs alternate sources of energy. So, there is a view to generate more and more power from renewa...
