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. 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.


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.


Estimated health effects from U.S. coal-fired power plant emissions

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.


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.


Electricity scenarios

In Reinventing Fire, Rocky Mountain Institute investigates the implications of four radically different future electricity scenarios - from a “business-as-usual” case to a network of intelligent microgrids powered largely by distributed renewables.


Reinventing Fire U.S. energy consumption, 2050

In 2050, Reinventing Fire envisions an economy that uses 71 quadrillion BTUs of primary energy—70% of that energy is supplied by wind, solar and biomass.


Cumulative new transmission requirements in four scenarios

Rocky Mountain Institute’s four scenarios for the future U.S. electricity system ( detailed here ) all have very different requirements for an expanded transmission infrastructure.


2050 installed capacity by case

The required generating capacity and its breakdown are very different in each of Rocky Mountain Institute’s four scenarios for the future U.S. electricity system (detailed here).
