Machine learning PODA model projects the impact of COVID-19 on US motor gasoline demand

Green Car Congress

The PODA model is a machine-learning-based model to project the US gasoline demand using COVID-19 pandemic data, government policies and demographic information. The Motor Gasoline Demand Estimation Module quantifies motor gasoline demands due to the changes in travel mobility. —Ou et al.

MIT study finds fuel economy standards are 6-14 times less cost effective than fuel tax for reducing gasoline use

Green Car Congress

In a study published in the journal Energy Economics , MIT researchers have found that a fuel economy standard is at least six to fourteen times less cost effective than a fuel tax when targeting an identical reduction in cumulative gasoline use (20% by 2050). —Karplus et al.

MIT study finds significant economic and environmental benefits from designing US LDVs to use higher octane gasoline (98 RON)

Green Car Congress

In a companion study to an SAE paper presented in April ( earlier post ), researchers at MIT have quantified the net economic and CO 2 emissions benefit that could be obtained by utilizing 98 RON gasoline in light-duty vehicles, based on reasonable assumptions for possible refinery changes and the evolution of the LDV fleet.

Researchers find consumers compensate for fuel-efficient car by buying bigger second vehicle; losing 60% of fuel economy savings

Green Car Congress

An analysis by a team from the University of California, Davis, MIT and Yale suggests that households that buy a fuel-efficient vehicle tend to compensate for that purchase by buying a bigger, more powerful second vehicle. This unintended effect could erode goals of fuel economy standard policies by up to 60%. Just as Anderson et al.

Separate MIT, IEA reports both outline major expansion in role of natural gas; caution on climate benefits

Green Car Congress

” The MIT report said that natural gas should be seen as a “ bridge ” to a low-carbon regime, rather than as the ultimate long-term solution itself. MIT: The Future of Natural Gas. Separately, the International Energy Agency (IEA) released its own report exploring the potential for a “golden age” of gas. Source: IEA.
