Alternative Energy Resources

Bio oil is most important alternative energy resources for human life due to the production of fossil fuel tend todecline. Numbers of researches have been developed on alternative energy resources, such as the conversion ofbiomass. The palm solid waste which is consisted of wood, stem and empty bunch having size of diameter in rangeof 2 to 10 mesh were used in this work. The pyrolysis method is selected in this research. This process was donein stainless steel reactor having length and length of 60.0 and 3.81 cm respectively at temperature of 450 to 600oCunder nitrogen flow. Gas chromatography HP 5890 is utilized to analyze of the bio oil result. The result achieved thehighest yield at 500oC and particle diameter of 2-6 mesh.

Alternative Energy Resources

The need of larger quantity of energy to fulfill the demand of energy, especially thefossil fuel, forced the government of almost all nation try to find the new kind of energy orknown as alternative energy resources. Fossil fuel as non-renewable energy resources wouldbe decreased by the time if the using of it not under controlled. This kind of energy resourcesused to handle almost all the people need of energy, such as for domestic uses, industrial,tourism, etc. The used of fossil fuel for that purposed mostly for generated the electricitypower (by built the power plant). Many natural energy resources can used to generateelectricity power plant, but there always be some advantages and bad impact, especially forthe environments. One of environmental friendly alternative energy resources is exploitingthe form of wind power.Keyword: alternative energy, wind energy, windmills farms, human well-being.

The rapid development of industry causes the need for fuel and energy to increase, especially fossil fuels (petroleum). This has the effect of an energy crisis. Biomass is of particular concern as one of the renewable energy sources to address the current energy crisis.  Biomass consists of hemiselulose, cellulose, and lignin that can be converted into liquids (bio-oils) of pyrolysis. One of the wastes that can be converted into bio-oil is tobacco waste. Tobacco waste is produced by more than 2 million tons eachs. The waste has the potential to be further processed into bio oil using fast pyrolysis method with efficient and quality bio-oil manufacturing measures. The bio-oil results from tobacco waste using the fast pyrolysis method have values of carbon, hydrogen, nitrogen, oxygen and other organic compounds and the H/C ratio is greater than the yield of tobacco waste bio-oil using the low pyrolysis method. Where the bio-oil of tobacco waste using the fast pyrolysis method has a high heating value equivalent to the distribution of hydrocarbons from biodiesel, which means it has the potential as an alternative energy to replace petroleum. The potential as a substitute fuel for petroleum must also be balanced with fast and efficient production, maximizing bio-oil production by selecting the reactor and the optimum temperature usedKeywords: Waste, Tobacco, Bio-Oil, Renewable Energy, Fast-pyrolisis

Purpose Ethiopia’s energy sector faces critical challenges to meeting steadily increasing energy demand given limited infrastructure, heavy reliance on hydroelectric power and underdevelopment of alternative energy resources. The purpose of this paper was to identify optimal least cost investment decisions for integrated energy source diversification. The authors seek to contribute to the relevant literature by paying particular attention to the role of public policy for promoting renewable energy investment and to better understand future energy security implications of various sources of uncertainty. Design/methodology/approach The authors created a dynamic linear programming model using General Algebraic Modelling System software to explore the national energy security implications of uncertainties associated with increasing technological advances and efficiency, and climate change scenarios. Findings To cope with the impacts of drought expected from future climate change on hydroelectric power production, Ethiopia would need to invest in the development of alternative energy resources. Such investment would not only enhance the sustainability and reliability of energy production but also increase costs. Greater rates of technological and efficiency innovations, however, were found to improve electricity diversification and reduce production costs and shadow prices or resource scarcity, and are thus key for enhancing energy security and reducing the risks posed by drought. Originality/value The dynamic linear programming model by the authors represents a flexible sector modelling tool for exploring the sustainability and efficiency of energy resource development pathways and evaluating the effects of different sources of uncertainty on the energy sector.
