U.S. installed capacity and electricity generation by energy resource, 1949 to 2009

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.


Building sector energy use, 2009

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 consumption in the U.S. economy, 2010-2050

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.


U.S. industry energy-saving potential, 2010–2050

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.


U.S. oil combustion: present and projected

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.


Primary energy consumption in U.S. industry

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 fuels: global production, 1800–2200

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.


Primary energy intensity of U.S. manufacturing industries, 2010

Industry has a huge variety of subsectors that differ markedly in energy consumption and intensity (energy used per $ of shipment).


Estimated water withdrawals in the U.S., 1950–2005

In 2005, half of U.S. water withdrawals were made by the electricity sector. A “business-as-usual” U.S. electricity future will increase reliance on large thermal power plants and keep water demands high.


U.S. natural gas consumption

In Reinventing Fire, natural gas consumption in 2050 is reduced by 36% relative to business-as-usual. This reduction is primarily enabled by improved efficiency in commercial and residential buildings and less reliance on natural gas in the electricity sector.
