ENVIRON 157 Chapter Notes - Chapter N/A: Gross Domestic Product, Liquefied Natural Gas, Energy Intensity
Document Summary
U. s. energy consumption grows at a slower rate than gross domestic product through 2050 as u. s. energy eciency continues to increase. Us total energy consumption from 2019 to 2050 is projected to be . 3% while it gross domestic product will me 1. 9% U. s. energy intensity continues its long-term decline through 2050. Residential and commercial sector energy efficiency improvements, increases in distributed generation, and regional population shifts partially offset the effects of higher growth rates in population, number of households, and commercial floorspace. Energy intensity declines in the industrial sector as a result of increased energy efficiency of new capital equipment and the higher growth rate in non-energy-intensive manufacturing industries relative to energy-intensive manufacturing industries. Energy use in the transportation sector per passenger-mile of travel in vehicles declines as newer, more fuel-efficient vehicles enter the market. In the transportation sector, adoption of energy-efficient technology and practices results in decreasing energy use per passenger-mile for rail, bus, and air travel.
