Energy utilization as a research area investigates the quantitative conversion, distribution, and consumption of energy within technical, biological, or socioeconomic systems, with emphasis on efficiency, losses, and optimization under thermodynamic and engineering constraints. It encompasses analytical and experimental methods to characterize energy flows, exergy destruction, and performance metrics across processes such as industrial manufacturing, transportation, buildings, and energy conversion technologies. Research typically integrates modeling, measurement, and control strategies to minimize primary energy input for a given service output, reduce waste heat and parasitic loads, and support system-level planning, often interfacing with energy systems analysis, demand-side management, and sustainability assessment.
According to a study published in Nano Energy, a research group led by Prof. Chen Chong from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has increased the photoelectric conversion efficiency ...
