Gasoline gallon equivalent

<p>Gasoline gallon equivalent (GGE) or gasoline-equivalent gallon (GEG) is the amount of an alternative <a href="/facts/Fuel/H8DIRL1j">fuel</a> it takes to equal the energy content of one liquid <a href="/facts/Gallon/HnvMkKIz">gallon</a> of <a href="/facts/Gasoline/lcnxq5BS">gasoline</a>. GGE allows consumers to compare the energy content of competing fuels against a commonly known fuel, namely gasoline.
</p><p>It is difficult to compare the cost of gasoline with other fuels if they are sold in different units and physical forms. GGE attempts to solve this. One GGE of CNG and one GGE of electricity have exactly the same energy content as one gallon of gasoline. In this way, GGE provides a direct comparison of gasoline with alternative fuels, including those sold as a gas (<a href="/facts/Natural_gas/9MYQ7NAP">natural gas</a>, <a href="/facts/Propane/E0b23KGh">propane</a>, <a href="/facts/Hydrogen_fuel/ezoKnHe9">hydrogen</a>) and as metered <a href="/facts/Electric_power/w61ID9yQ">electricity</a>.
