What is cogeneration and why is it important?

Cogeneration, also known as combined heat and power (CHP), is the simultaneous production of electricity and useful heat from the same energy source, typically fossil fuels or biomass. It is important because it enhances energy efficiency by utilizing the waste heat that would otherwise be lost in conventional power generation, resulting in lower fuel consumption and reduced greenhouse gas emissions. Cogeneration systems can provide reliable energy supply and contribute to energy security, making them a vital component in efforts to transition to more sustainable energy practices.
