Nonrenewable energy comes from sources that will run out or will not be replenished in our lifetimes—or even in many, many lifetimes.. Most nonrenewable energy sources are fossil fuels: coal, petroleum, and natural is the main element in fossil fuels. For this reason, the time period that fossil fuels formed (about 360300 million years ago) is called the Carboniferous Period.
