The U.S. burns 13 million barrels of oil a day for transportation. Most of this oil powers cars and light trucks. By 2050, the U.S. is expected to burn upwards of 17 million barrels of oil a day for transportation alone.
Increased adoption of energy efficient technologies as well as cogeneration and waste heat recovery systems will reduce energy use by an additional 4.7 quadrillion BTUs from business-as-usual. These and other changes (energy changes due fuel switching or transformation in other sectors) can reduce projected primary energy use by 27% in 2050.
The U.S. electricity sector has seen tremendous growth in the past 60 years. From 1949 to 2009, U.S. electricity consumption increased by a factor of 13. To meet this rising demand, the U.S has built vast amounts of new electricity generating infrastructure. The total U.S. installed capacity in 2009 was 998 GW, compared with just 65 GW in 1949.
By 2050, the U.S. can phase out its use of oil, coal and nuclear energy by relying on energy efficiency to reduce its energy needs, and meeting remaining the energy requirements with renewables and natural gas.
Electricity is 75% of primary energy consumed by U.S. buildings, but 68% of that electricity is lost in conversion and delivery. Oil and natural gas are almost 10 quads of energy, or 25% of total primary energy.
Energy use for U.S. industry is conventionally projected to grow from 24.4 quads in 2010 to 30.5 quads in 2050.
In 2010, more than four-fifths of energy use in U.S. industry came from fossil fuels. Natural gas is the dominant source of energy (~35%).
Fossil fuel combustion harms air quality and human health. A 2010 study by the Clean Air Task Force estimated that air pollution from coal-fired power plants accounts for more than 13,000 premature deaths, 20,000 heart attacks, and 1.6 million lost workdays in the U.S. each year. The total monetary cost of these health impacts is over $100 billion annually.
Humans have consumed roughly one-third of the planet’s technically and economically recoverable stock of fossil fuels. Projections from resource experts, although quite approximate, suggest that we are approaching peak consumption for oil (some assert the peak has already passed) and perhaps even for coal.
Automakers' profit margin typically hangs around 1% (in the U.S., 0.4%), far below the oil industry’s. The 2007–2008 global financial crisis sharply cut sales of new vehicles and the financial stability of the U.S. Big 3 auto manufacturers (Ford, General Motors, and Chrysler).
This chart shows why less than 0.5% of the energy in a typical modern auto’s fuel actually moves the driver, and only 5–6% moves the auto. An auto's weight is responsible for more than two-thirds of the energy needed to move it. All told, 86% of the fuel energy never reaches the wheels.
