1. Introduction
Energy is the driving force for economic development and
industrialization around the world. Fossil fuels are currently the
main resources that are used for fuel, as such they are an important
consideration in terms of finding solutions to the world's increasing
demand for energy [1]. However fossil fuels are limited, and
burning fossil fuels has a strongly negative impact on the environment [2]. Ever since the first oil crisis,renewable energy has attracted much by its renewability,sustainability and as a result of increased environmental awareness [3]. So,the role of renewable energy resources in electricity production is improving and it is currently receiving much research attention for its potential to replace with fossil fuel consumption in power plants.This has been
brought about by increased public awareness of the negative environmental impact of conventional methods of generating power,especially from coal and petroleum power plants [4].
