8th Natural Resources (C18) Practice Test

Coal energy comes from a fossil fuel that formed over millions of years. Because coal is finite and the rate at which we use it is far faster than its formation, it cannot be replenished on human timescales. That’s why energy from coal is nonrenewable. Saying it varies by region isn’t accurate for renewability—the resource itself is finite worldwide, even though regional availability or usage patterns may differ. Renewable energy, in contrast, comes from sources that naturally replenish quickly, like sunlight, wind, and flowing water.
