The context Biomass for energy plays a significant role in the EU renewable energy picture, with bioenergy expected to remain a key strategy for both the near and long term. Although biomass supplies within EU Member States are substantial, it will nonetheless be necessary to import significant volumes of fuel pellets and other forms of biomass in order to meet ambitious EU renewable energy tar...

wheat is the dominant cereal crop constituting the first staple food in iran. this paper studies the energy consumption patterns and the relationship between energy inputs and yield for wheat production in iranian agriculture during the period 1986 – 2008. the results indicated that total energy inputs in irrigated and dryland wheat production increased from 29.01 and 9.81 gj ha-1 in 1986 to 44...

open local energy requirements, the need for regional energy planning in the process of macro-planning can make significant energy. in this respect, the outer part of the direct effects of energy production and consumption locally effective, less energy planning processes will be huge. in this paper, the issue of continuity of energy supply, long-term access to resources and lower emissions fro...

geothermal investors need to be confident with the methods and results of exploration programs. also cutting the upfront cost of geothermal exploration will further encourage investors to consider investment in this emerging clean energy field. hence, it is of paramount importance to improve prospecting techniques in order to explore where economic concentrations of geothermal energy are to be ...

the renewable energy sources and plug-in electric vehicles (pevs) are becoming very popular because of the combination of high fuel costs and concerns about emission issues. this paper presents modelling and control of a building integrated fuel cell and plug-in electric vehicles (bifc-pev) in smart distribution systems. in bifc-pev system, conventional building elements could be replaced by sp...

In December 2015 the nations of the world agreed, in principle, to limit global warming to no more than 2 ◦C above pre-industrial levels. In order to achieve this goal, recent publications have shown that (1) more than 50% of known fossil fuel reserves need to remain unused, and (2) the timing of the transition away from fossil fuels needs to achieve 50% renewable energy by 2028, an expansion o...

In order to achieve self-sufficiency, increasing national milk production is a priority of the Algerian government. This will increase on-farm demand for electricity supplied primarily from fossil fuels, which contribute to the emissions of greenhouse gases and accelerate climate change. Hence, there is a need for promoting the use of renewable energy and low carbon technologies for the sustain...

The salinity difference between seawater and river water is a renewable source of enormous entropic energy, but extracting it efficiently as a form of useful energy remains a challenge. Here we demonstrate a device called "mixing entropy battery", which can extract and store it as useful electrochemical energy. The battery, containing a Na(2-x)Mn(5)O(10) nanorod electrode, was shown to extract ...

We study the optimal transition from fossil fuels to renewable energy in a neoclassical growth economy with endogenous technological progress in energy production. Technological innovations maintain a fairly constant cost of fossil fuel energy even as increased exploitation raises mining costs. Nevertheless, the economy transitions to renewable energy once energy costs escalate after about 80% ...
