ABSTRACT

As the world embraces sustainable energy, Hybrid Renewable Energy Systems (HRES) are becoming a practical and effective means of combining multiple renewable sources. These systems are crucial for enhancing environmental responsibility, improving energy efficiency, and ensuring reliability. This chapter examines the ecological and financial aspects of HRES. It focuses on how they can lower greenhouse gas emissions, enhance resource use, and reduce dependence on fossil fuels. Key environmental benefits of HRES include lower carbon dioxide emissions, better water and land use, and more effective waste management. The chapter discusses levelized cost of energy (LCOE), affordability, and how government incentives encourage adoption, which are the main economic topics addressed. Although upfront costs can be high, advancements in technology, integration with smart grids, and supportive financial policies are making these systems more appealing from an economic standpoint. Future research should focus on improving energy storage, enhancing grid compatibility, and refining hybrid setups to support wider use and long-term sustainability, as portrayed in the chapter.
