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.
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%).
Industry has a huge variety of subsectors that differ markedly in energy consumption and intensity (energy used per $ of shipment).
This chart depicts the 2010 primary energy intensities of U.S. industry by subsector versus shipments.
Based on Lawrence Berkeley National Laboratory (LBNL) technology reports, a number of measures were considered for adoption. This table features a sampling of these measures, with information on each measure’s technical potential, associated energy savings, and cost.
Premium-efficiency motors are normally assumed to cost more because they use more and better copper and iron. Yet analysis of all models on the 2010 U.S. market, in this case for 250 hp (TEFC, NEMA Type B) shows this is untrue despite standards’ having knocked the least efficient models off the market.
Based on a Lawrence Berkeley National Laboratory (LBNL) report on technologies that generate electricity from waste heat (and other waste energy sources), our analysis adopted the options summarized in the table.
RMI analysis predicts a net increase of industrial combined heat and power (CHP) installations of 109 GW, split between traditional cogeneration units and waste heat recovery to electricity systems.
The shift from steel to carbon fiber in the transportation sector reduces steel production. With the rapid adoption of lightweight vehicles, RMI estimates that, in 2050, the auto industry will require one-fifth the steel used in 2010.
Projected reduction in U.S. steel demand will reduce the energy required by the industrial sector by 111 trillion BTU/y in 2050.
