A nonrenewable resource is a natural resource that is consumed or used up faster than it can be made by nature.
Two main types of nonrenewable resources are fossil fuels and nuclear power. Fossil fuels, such as petroleum, coal, and natural gas, formed from plant and animal remains over periods from 50 to 350 million years ago.
Nuclear power is the use of nuclear energy (nuclear fission) to create energy inside of a nuclear reactor. Nuclear power is developed from atoms in certain elements, such as uranium.
