{ "item_title" : "Future of Decentralized Energy", "item_author" : [" Fouad Soliman", "Karima Mahmoud "], "item_description" : "Distributed generation, also distributed energy, on-site generation, or district/ decentralized energy, is electrical generation and storage performed by a variety of small, grid-connected or distribution system-connected devices referred to as distributed energy resources (DER). In this concern, conventional power stations, such as coal-fired, gas, and nuclear powered plants, as well as hydroelectric dams and large-scale solar power stations, are centralized and often require electric energy to be transmitted over long distances. By contrast, DER systems are decentralized, modular, and more flexible technologies that are located close to the load they serve, albeit having capacities of only 10 megawatts (MW) or less. These systems can comprise multiple generation and storage components; in this instance, they are referred to as hybrid power systems. DER systems typically use renewable energy sources, including small hydro, biomass, biogas, solar power, wind power, and geothermal power, and increasingly play an important role for the electric power distribution system.", "item_img_path" : "https://covers3.booksamillion.com/covers/bam/6/20/923/507/6209235077_b.jpg", "price_data" : { "retail_price" : "88.04", "online_price" : "88.04", "our_price" : "88.04", "club_price" : "88.04", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
