ONLiNE UPSC · Accepted Answer

Statement 1 is correct: Cogeneration, also known as combined heat and power (CHP), involves the simultaneous production of electricity and useful thermal energy from a single energy source.

Statement 2 is correct: Cogeneration systems can achieve overall efficiencies of up to 80%, which is significantly higher than the efficiency of traditional power generation methods that typically range between 30% and 50%.

Statement 3 is not correct: Cogeneration is not limited to large-scale industrial facilities; it can also be implemented in smaller commercial or residential settings, depending on the specific energy needs and system design.

Statement 4 is correct: By capturing and utilizing waste heat, cogeneration systems can reduce greenhouse gas emissions compared to separate heat and power generation, contributing to environmental sustainability.
