Integration of renewable energy solutions into virtual systems is a crucial step towards obtaining sustainable energy systems. Virtual systems provide for effective energy management, optimization, and trading processes, providing a platform for revolutionized energy solutions. A few of the renewable energy strategies appropriate for virtual systems are deliberated in this chapter, including hybrid renewable energy systems, block-chain-based energy trading, and artificial intelligence-based optimization. Second, the chapter also discusses the application of digital twins, additive manufacturing, and automation in increasing energy efficiency and sustainability. The results outlined are intended to lead the researchers and practitioners to develop robust renewable energy frameworks that will be usable in virtual environments.
