Did you know that many energy sources are nonrenewable?

Yeah, like oil and natural gas, right?

Root Explanation

Nonrenewable → It is formed from "non-" (meaning not) and "renewable" (from Latin "renovare", meaning to make new again). The word "nonrenewable" describes resources that cannot be made new again or replenished in a short time frame.

Memory Tip

Think of 'not' ('non-') being combined with 'able to be made new' ('renewable') — that's why nonrenewable refers to resources that cannot be replenished.
