In June 2021, the national average price for a gallon of gas was $3.09, according to data from AAA, but as of June 2022, it had topped $5. That marks a gain of over 60% in a single year.
When burned, one liter (0.26 U.S. gal) of gasoline emits about 2.3 kilograms (5.1 lb) of CO 2, a greenhouse gas, contributing to human-caused climate change. [ 93 ] [ 94 ] Oil products, including gasoline, were responsible for about 32% of CO 2 emissions worldwide in 2021.
The Clock is a film by video artist Christian Marclay.It is a looped 24-hour video supercut (montage of scenes from film and television) that feature clocks or timepieces. . The artwork itself functions as a clock: its presentation is synchronized with the local time, resulting in the time shown in a scene being the actual t
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] One GGE of CNG pressurized at 2,400 psi (17 MPa) is 0.77 cubic feet (22 litres; 5.8 US gallons).
TSFC or SFC for thrust engines (e.g. turbojets, turbofans, ramjets, rockets, etc.) is the mass of fuel needed to provide the net thrust for a given period e.g. lb/(h·lbf) (pounds of fuel per hour-pound of thrust) or g/(s·kN) (grams of fuel per second-kilonewton). Mass of fuel is used, rather than volume (gallons or litres) for the fuel ...
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 ...
One might summarize the timeline in the following way: the first 50 years were focused on the internal combustion engine and on refinery operations and, post 1970, emphasis has been placed on safety and automobile emissions. [19] 1900-1910 invention of spray carbeurator allowed use of "straight run gasoline" with vehicles.
the development of high-pressure gas mains, and compressors (1900s); these were capable of efficiently transporting gas over long distances, allowing one manufactured gas plant to supply a relatively large area – leading to the concentration of gas-manufacturing operations, instead of their geographic distribution; this resulted in gas-works ...
