Lesson Summary. To review, nonrenewable resources are those resources found inside the earth that are in a fixed amount. They are being used at a faster rate than they can be replenished and, therefore, cannot be renewed. These resources include the fossil fuels, which consist of oil, natural gas and coal. Nuclear energy is also a nonrenewable resource that uses uranium as an energy source. Each of these nonrenewable resources is either pumped or mined from the subsurface of the earth.
