Nonrenewable Energy Sources exist in fixed amounts and cannot be replenished. Which statement describes them?

• A. They Can Be Replenished
• B. They Exist in Fixed Amounts and Cannot Be Replenished
• C. They Are Renewable
• D. They Come From the Sun

Answer: (B)

Nonrenewable energy sources are limited and cannot be replenished. They exist in fixed amounts and take millions of years to form, so once we use them, they’re gone for a very long time. Coal, oil, and natural gas are examples. The energy in these fuels originally came from the sun, captured by ancient plants and animals, but the fuels themselves form so slowly that they don’t renew on human timescales. That’s why the statement that best describes them is that they exist in fixed amounts and cannot be replenished. The other ideas don’t fit because nonrenewables aren’t quickly replenished and aren’t considered renewable, even though their energy originally traces back to sunlight.
