  2. Energy efficiency in transport - Wikipedia

    en.wikipedia.org/wiki/Energy_efficiency_in_transport

    This means that a bicycle will use between 10 and 25 times less energy per distance travelled than a personal car, depending on fuel source and size of the car. This figure does depend on the speed and mass of the rider: greater speeds give higher air drag and heavier riders consume more energy per unit distance. In addition, because bicycles ...

  3. Energy-efficient driving - Wikipedia

    en.wikipedia.org/wiki/Energy-efficient_driving

    Example energy flows for a late-model (pre-2009) midsize passenger car: (a) urban driving; (b) highway driving. Source: U.S. Department of Energy [4] [5] Most of the fuel energy loss in cars occurs in the thermodynamic losses of the engine. Specifically, for driving at an average of 60 kilometres per hour (37 mph), approximately 33% of the ...

  4. Fuel efficiency - Wikipedia

    en.wikipedia.org/wiki/Fuel_efficiency

    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 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 ...

    Motorists who shifted travel modes from cars to bikes as their 'main method of travel' emitted 7.1 kg (16 lb) less CO 2 per day. [19] Regular cycling was most strongly associated with reduced life cycle CO 2 emissions for commuting and social trips. [19] Changing from motorised to non-motorised travel behaviour can also have significant effects.

    They determined that the cost of a ton of oil fuel used in steam engines was $5.04 and yielded 20.37 train miles system wide on average. Diesel fuel cost $11.61 but produced 133.13 train miles per ton. In effect, diesels ran six times as far as steamers utilizing fuel that cost only twice as much.

  7. Fuel economy in automobiles - Wikipedia

    Fuel consumption monitor from a 2006 Honda Airwave.The displayed fuel economy is 18.1 km/L (5.5 L/100 km; 43 mpg ‑US). A Briggs and Stratton Flyer from 1916. Originally an experiment in creating a fuel-saving automobile in the United States, the vehicle weighed only 135 lb (61.2 kg) and was an adaptation of a small gasoline engine originally designed to power a bicycle.

    Super credits for low-emission vehicles: The Regulation will give manufacturers additional incentives to produce cars with CO 2 emissions of 50 g/km or less (which will be electric or plug-in hybrid cars). Each of these vehicles will be counted as two vehicles in 2020, 1.67 in 2021, 1.33 in 2022, and then as one vehicle from 2023 onwards.
