This paper has focused on the integration of renewable energy, specifically the solar energy resources into conventional electric grid and deployment of smart architecture of hybrid energy system in the user-centric pervasive computing concept in the context of Kyoto Protocol for sustainable development of the rural and urban sector. A concept of next generation mobile smart-grid city for efficient real-time collaborative use of renewable and non-renewable energy sources at smart user-centric device for sustainable green environment in the context of climate change is proposed
