A nonrenewable source of energy means that there is only a limited supply that can be used. Nonrenewable resources, such as fossil fuels (coal, oil, natural gas) and nuclear fuels, cannot be replenished in a short time frame; they take millions of years to form, and once they are depleted, they cannot be replaced on a human timescale. Consequently, when we exhaust these resources, they are gone for good, and we must rely on alternative energy sources for the future.
What does it mean that a source of energy is nonrenewable? Once used, it needs to be reprocessed for reuse.
