Energy Cogeneration: What It Is, Types, Advantages, and Trends

Energy cogeneration simultaneously produces electricity and heat from a single fuel source, utilizing waste heat that would otherwise be lost in conventional systems. This boosts energy efficiency up to 80%, cutting costs and enhancing supply reliability. The main types are Topping Cycle (fuel generates electricity first) and Bottoming Cycle (waste heat generates electricity). Technologies include internal combustion engines, gas turbines, and steam turbines. In Brazil, biomass (sugarcane bagasse) and natural gas are the primary sources used.
