Fuel cladding

Fuel cladding is the thin-walled metal tube that seals nuclear fuel pellets in a fuel rod, preventing corrosion and fission product release; zirconium alloys are standard in light-water reactors.

fuel cost adjustment charge

A fuel cost adjustment charge is a line item on electricity bills that raises or lowers the per-kWh price to track the utility's actual fuel and purchased power costs, usually without profit.

Fuel Direct

Fuel Direct is the informal UK scheme for deducting gas and electricity debts directly from social security benefits, dating to 1980, with around 100,000 arrangements in April 2022.

Fuel dumping

Fuel dumping, also called fuel jettison or fuel dump, is the airborne release of unused fuel from an aircraft to reduce its weight enough to land safely.

Fuel economy in aircraft measures how much fuel an airplane burns to carry a payload a given distance, driven by engine efficiency, lift-to-drag ratio, and weight; jet fuel use doubled in efficiency from 1960 to 2008.

Fuel economy in automobiles

Fuel economy in automobiles is the distance a vehicle travels per unit of fuel, measured as miles per gallon in the US and liters per 100 km elsewhere.

Fuel efficiency

Fuel efficiency, also called gas mileage or fuel economics, is a measure of useful output per unit of fuel, commonly expressed for vehicles as miles per gallon.

Fuel hedging

Fuel hedging is the practice of using financial instruments like swaps and options to lock in fuel prices in advance, used most prominently by airlines, for whom fuel is a leading operating cost.

Fuel injection

Fuel injection is the delivery of fuel into an internal combustion engine under pressure instead of by a carburetor, with modern systems controlled by an electronic unit.

Fuel oil

Fuel oil is any liquid petroleum product made from crude oil and refined or blended to burn in engines, furnaces, boilers, and heaters, or as a solvent.

Fuel performance modeling

Fuel performance modeling is the computational simulation of nuclear fuel rod behavior in a reactor, and utilities and regulators use its predictions for safety analyses and licensing.

Fuel poverty

Fuel poverty is a household's inability to keep its home warm at reasonable cost, arising from low income, high energy prices, and an energy-inefficient dwelling; the term is used mainly in the UK and Ireland.

Fuel Price Stabilization Fund

The Fuel Price Stabilization Fund (Spanish: Fondo de Estabilización de Precios de los Combustibles) is Colombia's mechanism for smoothing domestic gasoline and diesel prices, created in 2007.

Fuel pump

A fuel pump is a device that moves fuel from a vehicle's tank to its engine at the pressure and volume the fuel system requires.

Fuel rod

A fuel rod is a long, slender tube, generally made of a zirconium alloy, holding stacked fissionable pellets and serving as the basic fuel element of a nuclear reactor.

Fuel surcharge

A fuel surcharge, also called a YQ or carrier-imposed surcharge, is an extra fee airlines add to fares and award tickets to recover fuel costs.

Fuel tank

A fuel tank, also called a gas tank, is a container that safely stores fuel on board a vehicle or aircraft and supplies it to the engine.

Fuel taxes in the United States

Fuel taxes in the United States, also known as gas taxes, are federal and state per-gallon excise taxes on motor fuels, funding roads mainly through the Highway Trust Fund.

Fuel Venture Capital

Fuel Venture Capital, formerly Rokk3r Fuel, is a Miami venture capital firm founded in 2017 by Jeff Ransdell, investing in early- and growth-stage technology companies including Replit and Shield AI.

Fuel wood

Fuel wood (firewood) is unprocessed woody biomass burned for cooking and heating; about 1.87 billion m3 of annual wood harvest is fuel, one-third of households rely on it, and it competes with charcoal, kerosene and LPG.

Fuel-driven dissipative supramolecular polymers

Fuel-driven dissipative supramolecular polymers are one-dimensional assemblies of small molecules held together by non-covalent interactions that exist only while a chemical fuel is consumed; the first example came in 2010.

FuelCell Energy

FuelCell Energy is an American clean energy company based in Danbury, Connecticut, founded in 1969, that makes molten carbonate fuel cell systems for baseload power and carbon capture.

Fueled by Ramen

Fueled by Ramen (FBR) is a New York-based Warner Music Group record label founded in 1996 in Gainesville, Florida, by John Janick and Vinnie Fiorello; it defined 2000s pop-punk and emo via Fall Out Boy, Panic! at the Disco, Paramore, and twenty one pilots.

FuelEU Maritime

FuelEU Maritime is an EU regulation, Regulation (EU) 2023/1805, limiting the well-to-wake greenhouse gas intensity of energy used on commercial ships calling at EU ports from 2025.

Fuengirola

Fuengirola, a Costa del Sol municipality in Málaga province, Spain; also Roman Suel, Andalusi Sohail. About 84,857 inhabitants (2025), 8 km of Blue Flag beaches, Sohail Castle, and a mass-tourism economy.

Fuenlabrada

Fuenlabrada, municipality in the southern Madrid metropolitan area, Community of Spain. Former 12th-century Castilian repopulation village; grew from 2,908 inhabitants in 1960 to about 190,000, an industrial and services city with Hospital de Fuenlabrada and Rey Juan Carlos University.
