Fossil fuel (such as oil, petroleum, natural gas and coal) and radioactive fuel (uranium) are the most common non-renewable energy sources. These resources are indeed renewable, but the fact that it takes thousands of years to grow or generate them, makes them non-sustainable and therefore non-renewable.
Air, water and land pollution are all consequences of using fossil fuels. In the pages that follow, we shall take a look at what each source of non-renewable energy is made of, and how they are used. Note that not all non-renewable energy comes from fossil fuels. There is also uranium, which is not a fossil fuel.ome of them exist infinitely (never run out, called RENEWABLE), the rest have finite amounts (they took millions of years to form, and will run out one day, called NON-RENEWABLE). Non-renewable energy is energy from fossil fuels (coal, crude oil, natural gas) and uranium.
