	Fuel efficiency
		Airlines are aiming for a further 25% fuel efficiency improvement by 2020.
		In 2000 IATA airlines adopted a voluntary goal and committed to improving their fuel efficiency by 10% between 2000 and 2010.
		IATA has launched a fuel action campaign and is working with industry partners to reduce fuel requirements and associated emissions.

	Fuel efficiency - Wikipedia, the free encyclopedia
		Fuel efficiency sometimes means the same as thermal efficiency or fuel economy.
		But fuel efficiency can also mean the output one gets for a unit amount of fuel input such as "miles per gallon" for an automobile.
		This last term "liters per 100 km" is also a measure of "fuel economy" where the input is measured by the amount of fuel and the output is measured by the distance travelled.

	cars - Fuel efficiency
		Fuel efficiency relates the efficiency of conversion to kinetic energy from energy contained in a carrier fuel, specifically in a transportation vehicle, such as an automobile.
		It should be noted that despite common usage, "fuel efficiency" is not a synonym for "fuel economy" or "gas mileage".
		This is significant because the improvements in fuel efficiency achieve over the last 20 years have NOT been translated into improvements in fuel economy--much of the savings have been offset by SUVs and power-enhancing improvements.

	Fuel economy in automobiles - Wikipedia, the free encyclopedia
		Fuel economy is the amount of fuel required to move a vehicle over a given distance.
		Fuel efficiency can also be hampered by unnecessary friction in the engine where drivers do not take advantage of situations where engine speed could be reduced.
		Efficiency increased from 24 MPG to 34 MPG at 70 MPH, and from 22 MPG to 30 MPG at 77 MPH.

		ICE engines are very inefficient at converting the fuel's chemical energy to mechanical energy, losing energy to engine friction, pumping air into and out of the engine, and wasted heat.
		In addition, diesels are about 30-35% more efficient than gasoline engines, and new advances in diesel technologies and fuels are making these vehicles more attractive.
		Fuel economy improvements of up to 1% may be achievable with more efficient alternator systems and power steering pumps.

		I truly believe that even the larger vehicles can be more efficient if it were mandated and the auto makers had their feet held to the fire.
		I understand the EPA conducts the fuel economy tests at an optimum 35 mph but does not even incorporate wind resistance (like a tunnel) into the test, thus misinforming the consumer by 2 or 3 miles per gallon.
		Lets all see how efficient each vehicle is, and not just when you are in the show room, but for the life of the car.

	Fuel Cell Today - FuelCell Energy Achieves Record Performance For Direct Fuel Cell/Turbine
		For example, gas engines have an electrical efficiency of 30 to 42 percent, low temperature fuel cells have an electrical efficiency of 30 to 35 percent and microturbines have an electrical efficiency of 25 to 30 percent.
		Fuel cells produce base load electricity giving commercial and industrial customers greater control over their power generation economics, reliability and emissions.
		Emerging state, federal and international regulations to reduce harmful greenhouse gas emissions consider fuel cell power plants in the same environmentally friendly category as wind and solar energy sources -- with the added advantages of running 24 hours a day and the capacity to be installed where wind turbines or solar panels often cannot.

	Online NewsHour: Increasing Fuel Efficiency -- July 31, 2001
		And so while some improvements in fuel economy might be possible in, say, a three- or four-year time frame for specific vehicle types, in order to put these changes into effect in the whole vehicle fleet, it would probably take ten to 15 years for the most ambitious changes.
		You could probably take the fuel economy of one of those cars from, say, 20 miles per gallon which would be the average fuel economy for one of those now, up to something in the vicinity of 25, 26 miles per gallon, which is a non-trivial increase.
		Saving five billion gallons over the next six years through fuel efficiencies and technologies as recommended by the NAS Study would be equivalent to parking that fleet for two years, not even running it for two years out of the six years.

		This year's cars, vans, sport-utility vehicles and pickups are slightly more fuel efficient than in 2004, according to a report released Thursday by the Environmental Protection Agency.
		The report was released as Congress completed work on an energy bill, which did not include tighter fuel efficiency standards sought by environmentalists.
		The popularity of light trucks, including vans and sport-utility vehicles with their thirstier engines, account for much of the fuel efficiency decline since 1987, according to the report.

		Petrol (Shellite, Coleman Fuel and similar proprietary fuels), kerosene and diesel are mixtures of a large range of hydrocarbons: a different fraction from the oil refinery cracking tower which converts the crude oil into useful fuels.
		A lot of the fuels have very similar figures for energy per mass (or grams to boil 1 litre), because what really counts is the number of carbon atoms in each molecule rather than the size of the molecule.
		A factor in fuel use for a liquid fuel stove is the hassle of lighting the stove: one tends to leave a liquid fuel stove running for short periods between courses because of this.

	Plasma combustion technology could dramatically improve fuel efficiency
		Kerosene, propane, gasoline and diesel fuel are all hydrocarbons, all made up of the same basic chemical constituents but separated by the size of their individual molecules.
		The more efficient fuels, and therefore more highly refined and expensive kerosene and propane, consist of fairly small chains of carbon and hydrogen atoms, whereas the less efficient and cheaper fuels, gasoline and diesel, are made of long chains of molecules.
		According to Coates, when electrodes attached at the spray nozzle of a fuel injector apply enough voltage to the fuel, energetic plasma electrons from voltage-induced breakdown of the fuel cause reactive species to be created, changing the basic chemical composition as the fuel becomes a plasma.

		The best fuel economy is gained by a combination of the gas petal to the floor with shifts at as low an rpm as possible to sustain your desired acceleration.
		At highway speeds, the greatest effect on fuel efficiency is the speed that you choose to drive at, coupled with the wind speed and direction.
		For example, you can get a feel for when the Insight enters fuel cut mode (not to be confused with idle stop), when no fuel is being consumed at all because the engine is continuing to be turned by the wheels.
