{{main|Hubbert peak theory}}
Hubbert models have been used to predict the production trends of various resources, such as [[peak gas|natural gas]] (Hubbert's attempt in the late 1970s resulted in an inaccurate prediction that natural gas production would fall dramatically in the 1980s), [[Peak coal|Coal]], [[Peak uranium|fissionable materials]], [[peak helium|Helium]], transition metals (such as [[Peak copper|copper]]), and [[peak water|water]].  At least one researcher has attempted to create a Hubbert curve for the [[whaling]] industry and caviar,<ref>Ugo Bardi and Leigh Yaxley.
