'Oil Crisis' was a term invented in 1973 when Arab nations cut oil supplies in response to support for Isreal. During the Carter administration the term energy crisis was heard more often in the United States. President Carter supported conservation and alternative energy sources among other solutions. This latter crisis was revived by the George W. Bush administration, though not with the intent of decreasing reliance on fossil fuels, but of increasing domestic supply of fossil fuels.

The term is usually used to refer to temporary shortages, rather than the fact that the total supply available is limited, and that even that cannot be used without facing the imperfectly understood dangers of global warming.
