This article presents a review about the application of various non‐conventional & renewable energy sources especially solar energy. Renewable energy sources are indigenous, and can therefore contribute to reducing dependency on energy imports and increasing security of supply. Development of renewable energy sources can actively contribute to job creation, predominantly among the small and medium sized enterprises which are so central to the community economic fabric, and indeed themselves form the majority in the various renewable energy sectors. Deployment of renewables can be a key feature in regional development with the aim of achieving greater social and economic cohesion within the community. Finally, this paper explores six broad types of renewable energy sources, their characteristics and typical application: solar energy, wind energy, bio energy, hydro energy, geothermal energy, wave and tidal energy.
