In the example provided by the US DoE in its final rule, an electric car with an energy consumption of 265 Watt hour per mile in urban driving, and 220 Watt hour per mile in highway driving, results in a petroleum-equivalent fuel economy of 335.24 miles per gallon, based on a driving schedule factor of 55 percent urban, and 45 percent highway ...
At the time of writing, the national average price of regular gas is $3.62 per gallon, $0.02 higher than this time last year. Drivers who use premium gas are paying $0.07 more this year than last ...
Depending on the marketplace, the price of natural gas is often expressed in currency units per volume or currency units per energy content. For example, US dollars or other currency per million British thermal units, thousand cubic feet, or 1,000 cubic meters. Note that, for natural gas price comparisons$, per million Btu multiplied by 1.025 ...
One GGE of natural gas is 126.67 cubic feet (3.587 m 3) at standard conditions. This volume of natural gas has the same energy content as one US gallon of gasoline (based on lower heating values: 900 BTU/cu ft (9.3 kWh/m 3) of natural gas and 114,000 BTU/US gal (8.8 kWh/L) for gasoline). [22]
Average fuel economy in the United States gradually declined until 1973, when it reached a low of 13.4 miles per US gallon (17.6 L/100 km; 16.1 mpg ‑imp) and gradually has increased since, as a result of higher fuel cost. [25] A study indicates that a 10% increase in gas prices will eventually produce a 2.04% increase in fuel economy. [26]
US marketed gas production reached a peak in 1973 at about 22.6 trillion cubic feet (640 km 3), and declined to a low of 16.9 trillion cubic feet (480 km 3) in 1986. But then instead of declining further, as predicted by the Hubbert curve , natural gas production rose slowly but steadily for the next 15 years, and reached 20.6 TCF in 2001.
Yet other definitions are in use for industrial gas, [5] where, in the US, a standard cubic foot for industrial gas use is defined at 70 °F (21.1 °C) and 14.696 psia (101.325 kPa), while in Canada, a standard cubic meter for industrial gas use is defined at 15 °C (59 °F) and 101.325 kPa (14.696 psia).
Currently over 700,000 vehicles enter the congestion charge area in Manhattan daily, according to the Metropolitan Transport Authority, traveling at an average of just 7 mph.With the congestion ...
