ORNL study finds best current use of natural gas for cars is efficient production of electricity for EVs

Green Car Congress

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. If CNG were to be eventually used in hybrids, the advantage of the electric generation/EV option shrinks. —Curran et al.

Rice study finds using natural gas for electricity and heating, not transportation, more effective in reducing GHGs

Green Car Congress

Rice University researchers have determined a more effective way to use natural gas to reduce climate-warming emissions would be in the replacement of existing coal-fired power plants and fuel-oil furnaces rather than burning it in cars and buses.

EIA projects decline in transportation sector energy consumption through 2037 despite increase in VMT, followed by increase

Green Car Congress

EIA’s Annual Energy Outlook 2019 projects continued robust growth in US energy production, emergence of the United States as an energy exporter, and a cleaner S electric power generation mix. This growth arises from increases in air transportation outpacing increases in aircraft fuel efficiency. trillion miles in 2018 to 3.5
