“…As seen, PV systems have important advantages to compete with other energy generation systems for sustainability such as availability, CO 2 emission, land use, fresh water consumption, social and environmental impacts. However, especially high initial and unit energy costs are major disadvantages although decreases with each passing year as a result of technological developments and investment (Varun et al, 2009). It is expected that the unit cost of PV energy will be half of present day value until 2025 that decline is quite high compared to other renewable systems (Fig.…”

Abstract. The conversion of solar energy into electricity reveals a huge importance in the production of "clean" energy , mainly when applied to decentralized production systems (micro-generation). However, there is the need to develop and optimize these processes in order to turn it more sustainable in economic and technological scoops. The main purpose of this work is to study the solar energy conversion into electricity through photovoltaic cells, characterizing the process efficiencies. This study intends to evaluate the energetic and exergetic efficiencies defining them as indicators in the formulation of a sustainability index. All the procedures are in a theoretical scope with an illustrative example in the end of this work.

The Smart Grid, regarded as the next generation power grid, uses two-way flows of electricity and information to create a widely distributed automated energy delivery network. Energy/power plays a critical role for social, economic and industrial development. Because of industrial generalization, especially in agricultural and economical activities, the energy demand has increased rapidly in developed countries. Generation and usage of energy has direct impact on modern power grid. In this scenario energy management is a hard task because load is dynamic and we don't have control over it. Renewable or undepleted energy resources have great applications and impact in current electric power system situation. For example it gives pollution free (green) energy which is environment and user friendly. It is cost effective; it uses natural resources for its generation and hence do not waste any coal, gas etc. There are many inducements to empower energy productivity. As current smart grid is complex and non linear in operation and design, it used an optimized method that provides maximum efficiency with minimum input. Our work depicts a case study of hybrid electric aircraft for achieving high performance.
