Renewable Energy Technologies for Sustainable and Smart Communities

Accelerating climate change, urban expansion, and rising electricity demand have intensified the transition toward renewable-powered smart communities. Advanced renewable energy technologies, coupled with intelligent digital infrastructures, provide a transformative pathway for achieving carbon neutrality, grid resilience, and sustainable urban development. This chapter presents a comprehensive examination of next-generation renewable systems—including solar photovoltaics, wind energy, energy storage technologies, and green hydrogen production—integrated within smart grid architectures and digitally managed energy ecosystems. Emphasis was placed on artificial intelligence–driven optimization, blockchain-enabled peer-to-peer energy trading, sector coupling, and decentralized microgrid configurations that enhance operational flexibility and energy autonomy at the community scale. The study further analyzes resilience-oriented infrastructure planning, cyber-physical security frameworks, and policy–economic mechanisms that govern renewable deployment in urban environments. Sustainable urban design principles and renewable zoning strategies are evaluated to demonstrate how spatial planning and regulatory alignment accelerate low-carbon transitions. Comparative insights from renewable-driven smart cities highlight best practices, implementation challenges, and scalable models for integrated energy management. By synthesizing technological innovation, governance structures, digital transformation, and community-level implementation strategies, this chapter establishes a multidisciplinary framework for renewable integration within sustainable and smart communities. The findings contribute to the advancement of resilient, secure, and economically viable energy ecosystems aligned with global decarbonization objectives and next-generation urban sustainability paradigms.
