Which non-renewable energy resources are fossil fuels?

Renewable means that it comes back again tomorrow even after we have used it as much as we can today, like sunlight, or wind or tidal power.

Tropical rainforests are non-renewable (well, not for hundreds and hundreds of years) and are NOT fossil fuel.

Most non-renewable sources of energy are fossil fuels, but there are many minerals like gold and silver, etc, that are not fossil fuels, but are non-renewable. Strictly speaking if we wait around for millions of years some of them might renew, but generally we say, if we use up all the gold in the world today, then there's no more tomorrow. Non-renewable!
