Fuel is any material that stores energy that can later be extracted to perform mechanical work in a controlled manner. Most fuels used by humans undergo combustion, a redox reaction in which a combustible substance releases energy after it ignites and reacts with the oxygen in the air. Other processes used to convert fuel into energy include various other exothermic chemical reactions and nuclear reactions, such as nuclear fission or nuclear fusion. Fuels are also used in the cells of organisms in a process known as cellular respiration, where organic molecules are oxidized to release usable energy. Hydrocarbons are by far the most common source of fuel used by humans, but other substances, including radioactive metals, are also utilized.

Famous quotes containing the words fuel and/or energy:
“Beware the/easy griefs, that fool and fuel nothing./It is too easy to cry AFRIKA!/and shock thy street,/and purse thy mouth,/and go home to thy Gunsmoke, to/thy Gilligans Island and the NFL.”
—Gwendolyn Brooks (b. 1917)
“The scholar may be sure that he writes the tougher truth for the calluses on his palms. They give firmness to the sentence. Indeed, the mind never makes a great and successful effort, without a corresponding energy of the body.”
—Henry David Thoreau (18171862)
