Solar Economy Elements

Abstract

Initially, the promotion of efficiency and renewable energies appears to be no more than a technological revolution: replacing energy technologies using fossil fuels with others which achieve efficient capture and use of solar energy in its multiple forms. However, the extraordinary development of renewable energies and their diffuse nature have opened the gates to a decentralized electrical model of distributed generation (DG). DG involves a set of small producers (usually renewable electricity) and users connected to a local grid, which is likewise connected to the general grid. Current DG dynamics tend to dilute the limits between generators and consumers, and other sectors. Buildings can generate their own electricity and evacuate excess to the grid. By using electrical vehicles (battery and hydrogen cells), the transport sector acquires electricity storage and generation capacity. These grids not only manage supply but also demand. All this leads to a level of management complexity unknown in the past. Yet these complex systems can be efficiently managed via the use of information technologies and communications (ITCs), leading to the creation of intelligent grids.
