The document discusses the development of methods for managing energy consumption and efficiency in energy systems by integrating renewable energy sources (RES) with software-defined machine-to-machine (M2M) communication technology. It analyzes various RES including wind, solar, and tidal energy, highlighting their operational characteristics, efficiencies, and challenges in supporting electricity supply for large cities. The study concludes that while wind energy shows the highest potential for efficient electricity generation, a combination of different power generation methods is essential due to the variable nature of renewable energy sources.
