While agricultural output increased as a result of the Green Revolution, the energy input to produce a crop has increased faster,[77] so that the ratio of crops produced to energy input has decreased over time. Green Revolution techniques also heavily rely on agricultural machinery and chemical fertilizers, pesticides, herbicides, and defoliants; which, as of 2014, are derived from crude oil, making agriculture increasingly reliant on crude oil extraction.
