Growth is led by developing regions such as China, India, Africa and other emerging economies. Additionally, to achieve proposed fuel-economy targets, personal vehicles will need to be smaller and lighter than they are today. This edition of the annual Outlook marks the first extension of the long-term energy forecast to 2040.
The 2009 results reflect a combination of factors, EIA said, including some particular to the economic downturn; other special circumstances during the year; and other factors that may reflect persistent trends in the economy and in energy use. Increased use of natural gas in place of coal caused the sector’s carbon intensity to decrease.
However, they also noted, high PTW efficiencies and the moderate fuel economies of current compressed natural gas vehicles (CNGVs) make them a viable option as well. The study investigated the the WTW energy and emissions from the use of natural gas in CNGVs with a range of CNGV fuel economy and natural gas compressor efficiency.
A) CNG light-duty cars vs. gasoline cars; (B) CNG heavy-duty vehicles vs. diesel vehicles; and (C) combined-cycle natural gas plants vs. supercritical coal plants using low-CH 4 coal. On the one hand, a shift to natural gas is promoted as climate mitigation because it has lower carbon per unit energy than coal or oil.
The current vehicle footprint-based Corporate Average Fuel Economy (CAFE) standards create a financial incentive for automakers to increase vehicle size, except under certain limited conditions of consumer preference for vehicle size, according to a study by University of Michigan researchers Kate Whitefoot and Steven Skerlos. 10 11 –5.17×10
tons of coal burned in a power-generation plant. Further improving its on-road performance, FCA’s TorqueFlite eight-speed automatic transmission benefits fuel economy, whether mated to the 2.0-liter CO 2 e output from 7.7 CO 2 e produced when powering 2.4 average American homes for one year. liter turbocharged I-4 or the 3.6-liter
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. Natural gas overtakes coal as the largest fuel for US electricity generation. from 2012 to 2040, compared to 1.2% per year, from 21.5
Monte Carlo simulation results for different drive cycles (as a proxy for fuel economy), operational ranges (64 or 80 km; 40 or 50 miles), EVSE Level 1 or 2, and battery replacement (0 or 1) scenarios. The relative TCO is most sensitive to the diesel truck’s fuel consumption (or fuel economy), VKT, and diesel fuel price scenario.
This indicates that the carbon intensity of the economy declined by about 4.2%. meant that the energy intensity of the economy fell by 2.3%. It is estimated that the miles per gallon (mpg) of light duty vehicles improved by 1.0% (20.4 mpg) from 2010 to 2011. percent—this coupled with economic growth of 1.8%
90% is from coal. Among their findings were: The order-of-magnitude variability in EGU emission factors by region yields the same degree of variability in EV emission factors and with the same spatial pattern (highest in the Northeast because of heavy reliance on coal). 1 , equivalent to a gasoline car with a fuel economy of 5.6
MPG ghg (0.05 L/100 km) for a BEV; on the other extreme are Botswana and Gibraltar (which generate 100% of their electricity from coal and oil), each with 29.0 MPG ghg (8.1 MPG ghg (4.2 MPG ghg (4.2 MPG ghg (4.6 MPG ghg (5.9 Color-coded world map of MPG-equivalent values (MPG ghg ) for BEVs.
Significant growth in the global middle class, expansion of emerging economies and an additional 2 billion people in the world will contribute to a 35% increase in energy demand by 2040, according to ExxonMobil’s latest Outlook for Energy report. The OECD represents the developed economies. Click to enlarge. Outlook for Energy.
Where energy resources are concerned, lignite, hard coal and uranium figure principally in car production. l/100 km (31 mpg US and 31.8 mpg) at the time of the market launch in 2007 or from between 6.4 mpg) at the time of discontinuation in 2013 to between 5.5 and 47 mpg)—depending on the tires fitted.
Current fuel economy for Class 8 trucks is estimated by the US Department of Energy at 6.0 mpg and projected to rise modestly to 6.8 mpg by 2025 (EIA, 2009). This is also equivalent to the amount of CO 2 emitted from 20 coal-fired power plants in a year. million barrels per day.
Anticipated population growth will reach nearly 9 billion in 2040 from about 7 billion today, and the global economy is projected to double—at an annual growth rate of nearly 3%—largely in the developing world. billion, as the world’s population grows and more people in developing economies are able to afford cars.
Many of the vehicles on the road in 2030 will have been built by 2015, and these will lower the fuel economy of the on-road fleet. Such assessments could determine the readiness of technologies to benefit from policy support to help bring them into the market at a volume sufficient to promote economies of scale. l/100 km) by 2050.
At the same time, energy efficiency gains and increased use of renewable energy sources and lower carbon fuels, such as natural gas, are expected to help reduce by half the carbon intensity of the global economy. On-road fuel economy varies significantly by region. Average fuel economy will rise from 25 to about 45 miles per gallon.
new appliance standards and CAFE) and changes in the way energy is used in the US economy. 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. million, or less than one-half the 2.9
EIA’s AEO2015 shows that the advanced technologies are reshaping the US energy economy. Fuel economy standards and changing driver behavior keep motor gasoline consumption below recent levels through 2040 in the Reference case. quadrillion Btu in 2040, as increases in fuel economy more than offset increases in LDV travel.
It does include the revised handling of fuel economy standards to reflect the proposal for light-duty vehicles in model years 2012-2016. New light duty vehicle efficiency reaches 40 mpg by 2035. The natural gas share falls slightly due to the completion of coal plants under construction, and the addition of new renewable capacity.
Closer to home, the federal fuel economy standards require the average fleet fuel economy of OEMs that sell vehicles in the USA to be 35.5 mpg by 2016. These companies have sunk costs invested in coal, gas and oil plants and are content in maximizing the return on these investments.
How does this sound: 100+ MPG in a regular vehicle? Plug-In Hybrids Are Cleaner (Even on a Coal Grid) [ to top ] This entire section is finally obsolete -- because we now have a definitive study by the Electric Power Research Institute and the Natural Resources Defense Council. What Are Plug-In Hybrids? The GREET 1.6
The company expects to demonstrate that during an eight hour delivery day simulation this plug-in hybrid vehicle can exceed 150 miles while exhibiting an efficiency of over 75 mpg (miles per gallon). Night time electric power is available from many renewable resources therefore reducing greenhouse gas (GHG) emissions.
"However," he continued, "If carmakers decide not to take advantage of this offer, AFS Trinity intends to raise the funds to begin modifying existing hybrids or manufacture its own 150 mpg SUVs and, eventually, 250 mpg sedans. It also may have a rheostat so drivers can select a performance or fuel-economy mode. Red Herring ).
It offers 18 models that deliver 30 mpg or more.

Trump also froze fines for fleet fuel-economy violators , after his administration lost a court battle to roll the fine amounts back—another move that indirectly likely suppressed the EV market. There’s been no about-face to a clean-energy economy. jobs, with 931,000 more jobs for the broader economy. businesses.
