I was reading about how a cogenerator can save energy in homes.

Really? How does that work?

Root Explanation

Cogenerator → It is formed from "co-" (meaning together) and "generator" (from Latin "generare", meaning to produce or create). The word "cogenerator" refers to a system or device that produces energy or power together with another process, typically in a more efficient manner.

Memory Tip

Think of 'together' ('co-') and 'producing' ('generator') to remember that a cogenerator is a system that produces energy together with another process.
