The development towards the usage of green energy sources is currently a major concern in today’s lifestyle due to the limited supply of fossil-based energy. Many have turned to alternative energy resources that are less polluting to the environment. Replacement of the vehicle’s fuel-based engine to an electric-based engine by using alternative or hybrid energy is one of the possible paths that many studies are conducted. In the aviation field, harvesting solar energy by using solar panel to charge aircraft on-board batteries could reduce the dependency on fuel. As with any other energy conversion technology, the solar panel performance needs to be monitored so that the power output can always be maintained at maximum available power. This paper presents a research and development of a system to monitor the health of photovoltaic panel installed on aircraft by measuring its voltage and current. The measurement is conducted using low power microcontroller. The system is capable to automatically measure the output of every solar panel installed in the system by connecting them with a matched load during the measurement process. The power output is then compared to the initial values prior to installation to determine how much power is currently being generated. By knowing the actual power output of each solar panel, less efficient or defective panel can be identified and replaced during maintenance. The system can be implemented not only for an aircraft but also applicable to other system that uses solar panel as their energy resources.

Energy is an effective economic power which can provide people with their basic necessities such as health, education, accommodation and protection. Increasing energy efficiency depends on development of the ability of energy sources with the combination of minimum posible cost, minimum risk and environment friendly facilities. Small and Medium Sized Entrerprises (SME) those can reflect this productivity of environment friendly energy to their production can be the cornerstone of social and economic development which is the determining economic factor in the countries’ social and economic development process. It is obvious that one of the main inputs of economic and social development is energy and providing it by using alternative sources is one of the most important parameters of sustainable development. Intense usage of fossil fuels causes a dependent condition in which SME’s cannot afford their energy demands totally by their own resources. As a result of an awareness research about alternative energy sources that will increase SME’s competitive capacity and sectoral tendency towards green energy sources, it is seen that consciousness of alternative energy and trends towards renewable energy resources are not strong enough. It is also identified that their level of awareness about how much their efficiency might be affected as a result of using new energy resources is rather low. Shortly in the frame of Vision 2023, recognising the main alternative energy resources of Turkey, it aims to identify the effects of tendency of SME’s towards alternative energy resources on their productivity.

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.

Wind energy is an alternative energy resources that abundant, enviromentally friendly and potential to be develop. The Utilization of wind energy can be applied at wind turbine. Ratio of vane amount as a runner was the variable that use on this research such as . Research use natural windfor 24 hours and data became fluctuatif. Data test obtain ratio runner 6:10 have greatest rotational speed, which is 373 rpm and mean rotational speed is 83.42 rpm. Runner ratio 6:12 have lowest rotational speed 291 rpm and mean rotational speed is 20.13
