Study estimates fuel economy improvements to US light-duty vehicles from 1975–2018 saved 2T gallons of fuel, 17B tons of CO2

Green Car Congress

A team from the University of Tennessee and the National Renewable Energy Laboratory (NREL) has the fuel savings due to fuel economy improvements over the past 43 years amount to approximately two trillion gallons of gasoline. Fleet-wide fuel economy gains produced large fuel savings. Greene et al.

EIA AEO2015 projects elimination of net US energy imports in 2020-2030 timeframe; transportation energy consumption drops

Green Car Congress

AEO2015 presents updated projections for US energy markets through 2040 based on six cases (Reference, Low and High Economic Growth, Low and High Oil Price, and High Oil and Gas Resource) that reflect updated scenarios for future crude oil prices. trillion cubic feet (Tcf) in the Low Oil Price case to 13.1

Perspective: US Needs to Transition to Hydrous Ethanol as the Primary Renewable Transportation Fuel

Green Car Congress

The oil price shocks of the 1970s led the Brazilian government to address the strain high prices were placing on its fragile economy. Brazil, the largest and most populous country in South America, was importing 80% of its oil and 40% of its foreign exchange was used to pay for that imported oil. by Brian J.

EIA Energy Outlook 2013 reference case sees drop in fossil fuel consumption as use of petroleum-based liquid fuels falls; projects 20% higher sales of hybrids and PHEVs than AEO2012

Green Car Congress

quadrillion Btu in 2035, as a result of fuel economy improvements achieved through stock turnover as older, less efficient vehicles are replaced by newer, more fuel-efficient vehicles. Beyond 2035, LDV energy demand begins to level off as increases in travel demand begin to exceed fuel economy improvements in the vehicle stock.

EIA 2035 reference case projects drop in US imports of petroleum due to modest economic growth, increased efficiency, growing domestic oil production, and biofuels

Green Car Congress

The outlook reflects increased use of LNG in markets outside of North America, strong domestic natural gas production, reduced pipeline imports and increased pipeline exports, and relatively low natural gas prices in the United States compared to other global markets. Use of renewable fuels and natural gas for electric power generation rises.

EIA: light duty vehicle energy consumption to drop 25% by 2040; increased oil production, vehicle efficiency reduce US oil and liquid imports

Green Car Congress

The rising fuel economy of LDVs more than offsets the modest growth in VMT, resulting in a 25% decline in LDV energy consumption decline between 2012 and 2040 in the AEO2014 Reference case. Generation from renewable fuels, unlike coal and nuclear power, is higher in the AEO2014 Reference case than in AEO2013.
