Which term describes a system that simultaneously generates heat and electricity from either the combustion of fuel or a solar heat collector?

• A. Combined Heat and Power (CHP)
• B. Converging technologies
• C. Cradle to cradle
• D. Dematerialization

Answer: (A)

This question tests the idea of generating heat and electricity together in one system to use energy more efficiently. A setup that does this captures the heat that would normally be wasted during power production (or uses solar heat) and delivers usable heat alongside electrical power. Because it leverages both outputs from the same energy source, it achieves higher overall efficiency than producing heat and power separately. This approach is called Combined Heat and Power. The other terms refer to different ideas: converging technologies means blending different technologies to create new capabilities; cradle to cradle is about sustainable product design and lifecycle; and dematerialization means using fewer materials to deliver goods or services.
