We encourage similar skepticism about the estimated effect of ethanol on gasoline prices generated from these models.
This analysis examines the effect of this downturn in driving on gasoline consumption (both total and per capita), and places the consumption in 2020 in a historical context. The results show that gasoline consumption per capita in 2020 was on par with that 55 years ago. Total consumption. Total consumption (millions of gallons).
a gasification-based drop-in advanced biofuels company, finalized a licensing agreement to use ExxonMobil Research and Engineering Company’s methanol-to-gasoline ( MTG ) technology to be incorporated into a “green gasoline” production facility.

The federal subsidy significantly favors larger battery packs to a stronger degree than their potential for additional gasoline savings. A 2011 paper by Michalek and colleagues found that strategies to promote adoption of HEVs and PHEVs with small battery packs offer more social benefits (i.e., Peterson and Michalek 2012.
Diesel is currently taxed at a lower level than gasoline in Europe; however, since 2011 the EC has been considering reversing that situation by making energy taxes systematically reflect the CO 2 performance of the energy product. A scheme including a decreased gasoline tax could bring about an increase in CO 2 emissions.
