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

http://www.rmi.org/RFGraph-Energy_consumption_in_US_economy
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. installed capacity and electricity generation by energy resource, 1949 to 2009

http://www.rmi.org/RFGraph-US_capacaity_elecricity_generation_by_energy
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

http://www.rmi.org/RFGraph-building_sector_energy_use
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.

 

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

http://www.rmi.org/RFGraph-US_industry_energy_saving_potential
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.

 

Primary energy consumption in U.S. industry

http://www.rmi.org/RFGraph-Primary_energy_consumption_US_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%).

 

U.S. natural gas consumption

http://www.rmi.org/RFGraph-US_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

http://www.rmi.org/RFGraph-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.

 

Where does the money go

http://www.rmi.org/RFGraph-where_does_the_money_go
Despite large aggregate expenditures on buildings, average U.S. consumers spend only ~4% of their total budget on fuel and electricity bills. Consumers have little incentive to reduce their energy bills, despite a variety of ways to do so profitably.

 

Historic and projected CO2 emissions from the U.S. electric sector, 1990–2050

http://www.rmi.org/RFGraph-CO2_emissions_from_US_electric_sector
Rocky Mountain Institute’s four scenarios for the future U.S. electricity system ( detailed here ) all have markedly different projected CO2 emissions over the next 40 years.

 

Reinventing Fire U.S. energy consumption, 2050

http://www.rmi.org/RFGraph-RF_US_energy_consumption
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.
