  Background and Objective: With population growth and the pattern changes of the societies towards consuming more energy and resources, the reduction of fossil fuel reserves, lack of access to freshwater resources, and increasing environmental pollutants caused people to feel the need of using new and cleaner methods of energy production. Therefore, the use of renewable energy systems is one way to solve some of these problems. Material and Methodology: The present research is descriptive-analytical with an applied approach that its purpose is to use renewable energy in two design scenarios including solar collector, biofuels, and incineration plant in order to meet the partial need for the power and freshwater of the island. The simulation of the two proposed scenarios was performed by MATLAB, TRNSYS, and AspenTech engineering software. Techno-economical evaluations of the power and freshwater produced along with environmental impacts were also analyzed and reported. Findings: According to the results, it was found that the second scenario consisting of incineration plant - biofuel produced more power and freshwater than the first scenario and can also facilitate the management of waste in the region, while the first design including a solar collector - biofuel despite its lower power production, supplied cleaner energy with much better financial results. Discussion and Conclusion: To summarize, both proposed scenarios have high potential to meet a major portion of the region's needs, and, based on strategic policies and sustainable development, each design can be selected according to the current priorities of the region.

  In order to preserve fossil fuel reservoirs, it is necessary to find renewable resources. One option is biomass that can be converted to biofuels. One of the most important biofuels is ethanol that has been regarded as the best substituent for benzene. Bioconversion is one of the bioremediation methods in which, biomass is converted to biofuel. In this process carbohydrate content is converted to simple sugars and then fermented to ethanol. With regard to the unique structure of lignocellusic materials the pretreatment is necessary that can be done by physical and chemical methods. In saccharification, the biomass is degraded to 5 and/or 6 carbon sugars and then the fermenter microorganism is selected based on the produced sugar. In order to improve final yeild, usually this two steps will be done simulatneously. One of the most important subjects in biofuel production is development of fermentation methods to reach maximum yield one of them is biphasic fermentation. Manuscript profile

  Nowadays demands for clean power source enhanced. Bio-fuel cell (BFC) can convert chemical energy to electrical energy. The enzyme-based biofuel cell (BFC) is a special fuel cell using enzyme as catalyst and can directly convert chemical energy to electrical energy. Bio-fuel cells are energy conversion devices based on bio-electrocatalysis leveraging on enzymes or microorganisms. Enzymatic fuel cells are promising low cost, compact and flexible energy resources. The basis of enzymatic fuel cells is transfer of electron from enzyme to the electrode surface and vice versa.. The DET of laccase enzyme has been studied using Multi-walled carbon nanotubes (MWCNTs)/Nafion polymer. Laccase was entrapped by nafion polymer . As Nafion is a proton exchange polymer but not an electron conductive, the MWCNTs were also used to facilitate electron transfer of laccase. Cyclic voltammetric results showed a well-defined redox peaks at 170 µA in a solution containing 10 µM o-dianisidine as a substrate for MWCNTs/Nafion composite. The cyclic voltammetric results showed that laccase immobilization on MWCNTs/Nafion is efficient. Therefore, this method can be used to fabricate biocathode of biofuels cellor laccase based biosensors. Manuscript profile

  One of the most important issues that all the countries of the world are dealing with today is the issue of energy supply. Energy supply is one of the most basic prerequisites for social development and economic growth of many societies, especially developing countries, and access to economically sustainable and environmentally friendly energy sources seems necessary in today''''s conditions. The decrease in fossil resource reserves and the increase in the price of oil and its products, as well as the need to pay attention to the reduction of environmental pollution caused by fossil fuels, have encouraged the countries of the world to use renewable and clean energies. Biofuels are one of the renewable resources that have attracted the attention of many European and American countries. Substitution of fossil fuels with biofuels has the potential to reduce some of the adverse environmental impacts of fossil fuel production and use, including emissions of conventional pollutants and greenhouse gases, depletion of finite resources, and dependence on unstable external suppliers. In addition to environmental benefits, the use of suitable biofuels can bring economic benefits such as reducing agricultural surplus reserves, reducing unemployment and dependence on imported oil, rural development, sustainable agriculture, etc. In the current study, after introducing and expressing the characteristics of two common biofuels, biodiesel and bioethanol, the general advantages and disadvantages of using biofuels, the economic, social and environmental considerations of using biofuels have been discussed.

  Microalgae are diverse group of simple organisms, which are incorporated in pharmaceutical, cosmic, nutritional and biodiesel productions. The amount of growth in microalgae is affected by physical and chemical conditions of growth environment. In commercial scale in order to achieve highest amount of biomass or biodiesel, it is necessary to use culture media with proper combination of materials. Therefore, in this study, effects of different values of temperature, light intensity, lighting period, saltiness and pH were tested by their effect on cell concentration, biomass, lipid and biodiesel production in desmodesmus microalgae. As a result, the best temperature for increase in cell concentration of microalgae was 25 degree of Celsius,  light intensity of 4500 lux, light period of 17 hours, saltiness of 5 ppm and pH of 8. The highest amount of biomass was achieved in light intensity of 3000 lux, 18 hours of lighting, saltiness of 5 ppm and pH of 9. The highest amount of lipid was produced at temperature of 26, light intensity of 4200 lux, lighting period of 16 hours, saltiness of 12 and pH of 9. Finally, the highest amount of biodiesel was produced at temperature of 26, light intensity of 4200, lighting period of  16 hours, saltiness of 11 and pH of 9. Manuscript profile
