Cogeneration refers to which practice?

• A. Using solar panels to generate electricity
• B. Capturing carbon dioxide for storage
• C. Producing electricity from wind energy
• D. Using waste heat to generate electricity

Answer: (D)

Cogeneration, or combined heat and power, is about producing electricity and capturing usable heat from the same energy source. Instead of letting the heat from power generation go to waste, that heat is redirected to heating buildings, producing hot water, or driving industrial processes. This use of heat alongside electricity makes the overall energy use much more efficient because one energy input yields two useful outputs. The idea of using waste heat to generate electricity reflects that heat is not wasted but repurposed to support additional power production, which is what defines cogeneration.
