At this point the quota meant that biofuel production accounted for 40% of the entire US corn crop. According to research sponsored by the United States government, the World Bank, and other organizations, there is no clear link between
1040-399: A result of higher fuel cost. A study indicates that a 10% increase in gas prices will eventually produce a 2.04% increase in fuel economy. One method by car makers to increase fuel efficiency is lightweighting in which lighter-weight materials are substituted in for improved engine performance and handling. Identical vehicles can have varying fuel consumption figures listed depending upon

Fuel consumption figures are expressed as urban , extra urban and combined , measured according to ECE Regulations 83 and 101 – which are the based on the European driving cycle ; previously, only the combined number was given. Australia also uses a star rating system, from one to five stars, that combines greenhouse gases with pollution, rating each from 0 to 10 with ten being best. To get 5 stars
1200-572: A top speed of 120 km/h (74.6 mph). EU fuel consumption numbers are often considerably lower than corresponding US EPA test results for the same vehicle. For example, the 2011 Honda CR-Z with a six-speed manual transmission is rated 6.1/4.4 L/100 km in Europe and 7.6/6.4 L/100 km (31/37 mpg ) in the United States. In the European Union advertising has to show carbon dioxide (CO 2 )-emission and fuel consumption data in
1280-546: A vacuum with frictionless wheels could travel at any speed without consuming any energy beyond what is needed to get the car up to speed. Less ideally, any vehicle must expend energy on overcoming road load forces, which consist of aerodynamic drag, tire rolling resistance, and inertial energy that is lost when the vehicle is decelerated by friction brakes. With ideal regenerative braking , the inertial energy could be completely recovered, but there are few options for reducing aerodynamic drag or rolling resistance other than optimizing
1360-550: A veto threat, "We are the Congress of the United States. We can write things even though the president may not like them." Democrats said that the tax measure was modest and only took back tax breaks the oil companies received in 2004 and that they did not need them with oil prices at about $ 90 a barrel. The House version of the bill (with $ 13 billion raised from the oil industry, a mandate that utilities rely on renewable energy for at least 15 percent of their power generation, and

For example, the current model Skoda Octavia, using Volkswagen engines, has a combined European fuel efficiency of 41.3 mpg ‑US (5.70 L/100 km) for the 105 bhp (78 kW) petrol engine and 52.3 mpg ‑US (4.50 L/100 km) for the 105 bhp (78 kW) — and heavier — diesel engine. The higher compression ratio
1600-402: Is a significant factor in air pollution, and since the importation of motor fuel can be a large part of a nation's foreign trade , many countries impose requirements for fuel economy. Different methods are used to approximate the actual performance of the vehicle. The energy in fuel is required to overcome various losses ( wind resistance , tire drag , and others) encountered while propelling
1680-534: Is helpful in raising the energy efficiency, but diesel fuel also contains approximately 10% more energy per unit volume than gasoline which contributes to the reduced fuel consumption for a given power output. In 2002, the United States had 85,174,776 trucks, and averaged 13.5 miles per US gallon (17.4 L/100 km; 16.2 mpg ‑imp ).

2640-1047: The Netherlands. When the US National Maximum Speed Law 's 55 mph (89 km/h) speed limit was mandated from 1974 to 1995, there were complaints that fuel economy could decrease instead of increase. The 1997 Toyota Celica got better fuel-efficiency at 105 km/h (65 mph) than it did at 65 km/h (40 mph) (5.41 L/100 km (43.5 mpg ‑US ) vs 5.53 L/100 km (42.5 mpg ‑US )), although even better at 60 mph (97 km/h) than at 65 mph (105 km/h) (48.4 mpg ‑US (4.86 L/100 km) vs 43.5 mpg ‑US (5.41 L/100 km)), and its best economy (52.6 mpg ‑US (4.47 L/100 km)) at only 25 mph (40 km/h). Other vehicles tested had from 1.4 to 20.2% better fuel-efficiency at 90 km/h (56 mph) vs. 105 km/h (65 mph). Their best economy

Fuel economy in automobiles The fuel economy of an automobile relates to the distance traveled by a vehicle and the amount of fuel consumed . Consumption can be expressed in terms of the volume of fuel to travel a distance, or the distance traveled per unit volume of fuel consumed. Since fuel consumption of vehicles
2800-511: The Renewable Fuel Standard increased corn prices by 30% and those of soybeans and wheat by 20%. These price hikes increased corn cultivation by 8.7% which necessitated additional fertilizer usage that increased rates of nitrous oxide emissions and water pollution. The price hikes also incited land-use change that increased the total U.S. cropland extent by 2.4% through 2016 and resulted in substantial carbon emissions. In total,
2880-474: The Senate to resolve their differences. The House took up the energy bill again in December, passing a new version on December 6. This version, renamed the "Energy Independence and Security Act of 2007", restored the oil industry tax increases of the original bill. It also added a requirement that U.S. electric utilities must obtain 15 percent of their power from renewable sources by 2020. When this bill

The U.S. Chamber of Commerce said that the bill would punish an industry that has made many Americans wealthy for generations, adding that "Congress and various Administrations have perhaps imposed more regulations on
3120-399: The U.S. will become a less attractive place to produce oil and natural gas. This essentially creates incentives for foreign importation and could kill manufacturing jobs in an industry that employs nearly 1.8 million Americans." Congressmen representing automobile manufacturing regions objected to the proposed increase in fuel economy standards. They said the measure would sharply increase
3200-647: The USA. Most European vehicles cited in the CSI study run on diesel engines, which tend to achieve greater fuel efficiency than gas engines. Selling those cars in the United States is difficult because of emission standards, notes Walter McManus, a fuel economy expert at the University of Michigan Transportation Research Institute. "For the most part, European diesels don’t meet U.S. emission standards", McManus said in 2007. Another reason why many European models are not marketed in

Published fuel economy is subject to variation between jurisdiction due to variations in testing protocols. One of the first studies to determine fuel economy in the United States was the Mobil Economy Run , which was an event that took place every year from 1936 (except during World War II ) to 1968. It
3680-543: The bill created a Strategic Energy Efficiency and Renewables Reserve, an account to hold additional money received by the Federal Government as a result of the enactment of the act, and to offset the cost of subsequent legislation. Opponents argued that the act would "increase Americans reliance on foreign sources of energy by making new domestic exploration and production more costly" and stated that markets should drive U.S. energy policy. They were concerned that

5280-520: The sources of energy loss in moving a vehicle may be summarized as follows: Fuel-efficiency decreases from electrical loads are most pronounced at lower speeds because most electrical loads are constant while engine load increases with speed. So at a lower speed, a higher proportion of engine horsepower is used by electrical loads. Hybrid cars see the greatest effect on fuel-efficiency from electrical loads because of this proportional effect. Technologies that may improve fuel efficiency, but are not yet on
5360-437: The test cycle known as ECE-15, first introduced in 1970 by EC Directive 70/220/EWG and finalized by EEC Directive 90/C81/01 in 1999. It simulates a 4,052 m (2.518 mile) urban trip at an average speed of 18.7 km/h (11.6 mph) and at a maximum speed of 50 km/h (31 mph). The extra-urban driving cycle or EUDC lasts 400 seconds (6 minutes 40 seconds) at an average speed 62.6 km/h (39 mph) and
5440-446: The testing methods of the jurisdiction. Lexus IS 250 – petrol 2.5 L 4GR-FSE V6 , 204 hp (153 kW), 6 speed automatic, rear wheel drive Since the total force opposing the vehicle's motion (at constant speed) multiplied by the distance through which the vehicle travels represents the work that the vehicle's engine must perform, the study of fuel economy (the amount of energy consumed per unit of distance traveled) requires
5520-419: The type of feedstocks produced, the management practices used to produce them, prior land use, and any land-use changes that their production might incur. In addition to greenhouse-gas emissions, production and use of biofuels affect air quality, water quality, water use, and biodiversity. A 2018 US EPA report to the Congress confirmed conclusions of the previous report and found that the expected transition to
5600-416: The vehicle's shape and the tire design. Road load energy or the energy demanded at the wheels, can be calculated by evaluating the vehicle equation of motion over a specific driving cycle. The vehicle powertrain must then provide this minimum energy to move the vehicle and will lose a large amount of additional energy in the process of converting fuel energy into work and transmitting it to the wheels. Overall,
5680-728: The vehicle, and in providing power to vehicle systems such as ignition or air conditioning. Various strategies can be employed to reduce losses at each of the conversions between the chemical energy in the fuel and the kinetic energy of the vehicle. Driver behavior can affect fuel economy; maneuvers such as sudden acceleration and heavy braking waste energy. Electric cars do not directly burn fuel, and so do not have fuel economy per se, but equivalence measures, such as miles per gallon gasoline equivalent have been created to attempt to compare them. The fuel efficiency of motor vehicles can be expressed in multiple ways: The formula for converting to miles per US gallon (3.7854 L) from L/100 km
5760-503: The wake of the 2012 North American drought , which had a devastating effect on the US corn crop, there were calls for the quota imposed by the Renewable Fuel Standard to be suspended. In August 2012, 25 senators and over 100 house members echoed the demand. The head of the Food and Agriculture Organization , José Graziano da Silva , called on the United States to suspend the quota. Writing in
5840-571: The year 2020, it is estimated to save Americans a total of $ 22 billion and have a significant reduction in emissions equivalent to removing 28 million cars from the road. Title I is responsible for 60% of the estimated energy savings of the bill. Title II contains the first legislation that specifically requires the creation of biomass-based diesel fuel, which is the addition of renewable biofuels to diesel fuel . To be labeled as Biomass-based Diesel, fuel must be able to reduce emissions by 50 percent when compared to petroleum diesel. As of now, Biodiesel
5920-621: Was designed to provide real, efficient fuel efficiency numbers during a coast-to-coast test on real roads and with regular traffic and weather conditions. The Mobil Oil Corporation sponsored it and the United States Auto Club (USAC) sanctioned and operated the run. In more recent studies, the average fuel economy for new passenger car in the United States improved from 17 mpg (13.8 L/100 km) in 1978 to more than 22 mpg (10.7 L/100 km) in 1982. The average fuel economy for new 2020 model year cars, light trucks and SUVs in
6000-437: Was introduced to the Senate, the new provisions became the focus of debate. The White House and Sen. Domenici warned that Bush would veto the bill because of the tax portion. Senate Minority Leader Mitch McConnell (R-Ky.) said Democrats had "shown how to snatch defeat from the jaws of victory" by "inserting an enormous tax hike, a tax hike they knew would doom this legislation." Reid said Congress should not be intimidated by
6080-577: Was not present. The revised Senate bill passed 86–8 on December 13. The House approved this final version 314–100 on December 18, and President Bush signed it the following day. A 2011 report from the United States National Research Council investigated the potential economic and environmental effects of reaching the Renewable Fuel Standard, which mandates that 35 billion gallons of ethanol-equivalent biofuels and 1 billion gallons of biomass-based diesel be consumed in
6160-419: Was partly based on a belief that cars achieve maximum efficiency between 40 and 50 mph (65 and 80 km/h) and that trucks and buses were most efficient at 55 mph (89 km/h). In 1998, the U.S. Transportation Research Board footnoted an estimate that the 1974 National Maximum Speed Limit (NMSL) reduced fuel consumption by 0.2 to 1.0 percent. Rural interstates, the roads most visibly affected by
6240-399: Was reached at speeds of 40 to 90 km/h (25 to 56 mph) (see graph). Officials hoped that the 55 mph (89 km/h) limit, combined with a ban on ornamental lighting, no gasoline sales on Sunday, and a 15% cut in gasoline production, would reduce total gasoline consumption by 200,000 barrels a day, representing a 2.2% drop from annualized 1973 gasoline consumption levels. This
6320-846: Was studied in 2010. The most recent study indicates greater fuel efficiency at higher speeds than earlier studies; for example, some vehicles achieve better fuel economy at 100 km/h (62 mph) rather than at 70 km/h (43 mph), although not their best economy, such as the 1994 Oldsmobile Cutlass Ciera with the LN2 2.2L engine, which has its best economy at 90 km/h (56 mph) (8.1 L/100 km (29 mpg ‑US )), and gets better economy at 105 km/h (65 mph) than at 72 km/h (45 mph) (9.4 L/100 km (25 mpg ‑US ) vs 22 mpg ‑US (11 L/100 km)). The proportion of driving on high speed roadways varies from 4% in Ireland to 41% in
6400-482: Was supported by the Alliance to Save Energy , a coalition of light bulb manufacturers, electric utilities and conservation groups. The group estimated that lighting accounts for 22% of total U.S. electricity usage, and that eliminating incandescent bulbs completely would save $ 18 billion per year (equivalent to the output of 80 coal plants ). Light bulb manufacturers also hoped a single national standard would prevent
