Natural Resources

May be classified as non-renewable (e.g. coal, oil) and renewable. The latter may further be classified as unconditionally renewable (e.g. solar, tidal or wind energy) and conditionally renewable (e.g. fish, forest products). Conditionally renewable sources will last indefinitely if not over-exploited because that part of the resource that is used can be replaced through natural processes.
