Answer: Congeneration is a process of producing electricity and heat simultaneously.
Step-by-step explanation:
The rationality of congeneration lies essentially in the saving of energy resources in the face of a conventional configuration that produces the same amounts of useful heat and work, which is usually converted to electrical or mechanical energy.
Congeneration is a very efficient energy production process, providing several benefits. At a local level, it can significantly reduce the user's energy bill, while at a global level it reduces the consumption of fossil fuel reserves, leading to a significant reduction in the environmental impact of using these fuels.
