Cogeneration, also known as combined heat and power (CHP), is an efficient energy system that simultaneously produces electricity and useful heat from the same energy source. This process maximizes energy use by capturing heat that would otherwise be wasted during electricity generation, making it a more sustainable option for power production. Typically, cogeneration systems are used in industrial facilities, large buildings, and district heating applications. By utilizing fuels like natural gas or biomass, cogeneration can significantly reduce greenhouse gas emissions and lower energy costs, contributing to a more environmentally friendly energy landscape.
