Source: Adapted from BP Statistical Review of World Energy. The oldest continuously operated oil well, called McClintock #1, is located south of Titusville, Pennsylvania, and started operations in 1861. Its initial output was about 50 barrels of oil per day, and after more than 155 years of operation, the well

Automobile Emission Factors
Source: EPA. Three major factors influence the emission level of vehicles: Vehicle characteristics. The weight of the vehicle, including its load, has a direct impact on combustion, along with its aerodynamics and the friction between its parts (gear, transmission, brakes, wheels, etc.). As a vehicle ages, it tends to consume
Demand for Refined Petroleum Products by Sector in the United States
Source: BTS, National Transportation Statistics. Over the decades, transportation accounted for a growing share of oil consumption in the United States, while the amount of oil consumed by the industrial sector remained the same. By 2018, transportation accounted for 70.4% of petroleum consumption, while this share was 64.5% in 1990.

Sources: Federal Reserve Bank of St. Louis & US Department of Transportation, Federal Highway Administration. There is an inversely proportional relationship between energy prices and changes in travel demand, as evidenced by the United States. When oil prices rise sharply, growth rates in vehicle miles traveled (VMT) plummet, which is
Fuel Consumption and Fuel Efficiency
Among the factors of energy consumption by transportation, vehicle fuel efficiency plays a significant role. With an increase in fuel efficiency (in miles per gallon), marginal fuel consumption decreases. The most important fuel consumption benefits are achieved in the lower ranges of improvements. For instance, an improvement from 10 to
Total Motor Vehicle Fuel Consumption and Travel in the United States
Source: BTS, Table 4-9. Motor vehicles, fuel consumption and travel data include light duty vehicles, buses, trucks and motorcycles. The Oil Shocks of the 1970s and early 1980s were accompanied by an increase in the fuel efficiency of motor vehicles. While in 1970, a motor vehicle was consuming on average
Typical Energy Use for a Car
Source: US Department of Energy. Cars tend to be inefficient in their use of energy since only a marginal amount of the energy they consume is actually used to provide momentum (around 15-20% depending on the type of vehicle). What remains is lost in the engine, the power to wheels,
Energy Consumption by Transportation Mode in the United States, 1960-2020
Source: BTS, National Transportation Statistics. Road accounts for about 85% of all the energy consumed by transportation in the United States, a share that has remained relatively constant over time. After decades of continuous growth, energy consumption by the transportation sector is leveling off. This is in part due to
