When people talk about energy conservation, usually they mean using less fuel (see [[fuel conservation]]).

Almost all, about 95%, of human [[primary energy]] comes from fuels (as opposed to [[flow]]s). These fuels go into [[power plant]]s, see figure 1, [[engine]]s, [[heater]]s and anything else that humans derive [[work]] or [[heat]] from. This percentage is slightly different for [[electrical generation]]; 85% of the primary energy to [[generate electricity]] comes from fuels (as opposed to flows).

==Types of fuel==
When a fuel is used, it undergoes some process that leaves it in a form with less energy. This means that most fuels are [[renewable and sustainable energy|non-renewable]], but may be found extensively enough as to be considered [[renewable and sustainable energy|sustainable]]. [[Flow]]s, like [[wind]], are not considered fuels and are a class of primary energy supply entirely different from fuels - ''for more information on this difference please visit the page: [[fuel vs flow]]''.

[[Primary fuel]]s include [[nuclear fuel]]s, [[biofuel]]s and [[fossil fuel]]s. Often primary fuels are processed to make something chemically distinct from how they were harvested from a [[natural resource]]. For example [[crude oil]] is a primary fuel that undergoes [[fractional distillation]] to become products more useful to the consumer.
