Retail markup over crude oil and wholesale gasoline, 2014–2019 Oil, gas, and diesel prices RBOB Gasoline Prices. In 2008, a report by Cambridge Energy Research Associates stated that 2007 had been the year of peak gasoline usage in the United States, and that record energy prices would cause an "enduring shift" in energy consumption practices.

Consumption map of a 1.5-litre three-cylinder diesel engine. A consumption map or efficiency map [1] is a chart that displays the brake-specific fuel consumption of an internal combustion engine at a given rotational speed and mean effective pressure, in grams per kilowatt-hour (g/kWh).
Updates on reimplementing the Graph extension, which will be known as the Chart extension, can be found on Phabricator and on MediaWiki.org. Federal gasoline tax [ 14 ] The first federal gasoline tax in the United States was created on June 6, 1932, with the enactment of the Revenue Act of 1932 , which taxed 1¢/gal (0.3¢/L).
The fuel consumption per mile or per kilometre is a more appropriate comparison for aircraft that travel at very different speeds. [citation needed] There also exists power-specific fuel consumption, which equals the thrust-specific fuel consumption divided by speed. It can have units of pounds per hour per horsepower.
Fuel consumption is a more accurate measure of a vehicle's performance because it is a linear relationship while fuel economy leads to distortions in efficiency improvements. [2] Weight-specific efficiency (efficiency per unit weight) may be stated for freight , and passenger-specific efficiency (vehicle efficiency per passenger) for passenger ...
Fuel consumption is the reciprocal of fuel economy, and measures the fuel used to drive a fixed distance (units of gal/100 miles or kWh/100 miles). [36] The unit of Gal/100 miles is accurately described as fuel consumption in some EPA brochures, but this unit appears in the fuel economy section of the Monroney label (which does not use the term ...
Example of a Sankey diagram Sankey's original 1898 diagram showing energy efficiency of a steam engine. Sankey diagrams are a data visualisation technique or flow diagram that emphasizes flow/movement/change from one state to another or one time to another, [1] in which the width of the arrows is proportional to the flow rate of the depicted extensive property.
