Energy conversion is the process of transforming one form of energy into another, usually in a more useful or practical form. This area of research involves studying the various methods and techniques used to convert energy from one form to another, such as converting mechanical energy into electrical energy or converting heat energy into mechanical energy. Energy conversion is a critical aspect of many aspects of modern society, including in the fields of renewable energy, transportation, and power generation. Researchers in this area work to develop more efficient and sustainable methods of energy conversion to meet the growing demands for energy in a clean and environmentally-friendly way.
