CMU study finds that coal retirement is needed for EVs to reduce air pollution

Green Car Congress

Electric vehicles charged in coal-heavy regions can create more human health and environmental damages from life cycle air emissions than gasoline vehicles, according to a new consequential life cycle analysis by researchers from Carnegie Mellon University.

EPA GHG Inventory shows US GHG down 1.7% y-o-y in 2019, down 13% from 2005

Green Car Congress

This decrease was driven largely by a decrease in emissions from fossil fuel combustion resulting from a decrease in total energy use in 2019 compared to 2018 and a continued shift from coal to natural gas and renewables in the electric power sector. The number of vehicle miles traveled (VMT) by light-duty vehicles (i.e.,

ANL: life-cycle water consumption of fuel cell vehicles can be cut in half compared to that of conventional ICE vehicles

Green Car Congress

The life-cycle water consumption of fuel cell electric vehicles using hydrogen produced from natural gas with steam methane reforming is almost 50% less than the life-cycle water consumption of conventional internal combustion engine vehicles using gasoline, according to a study by researchers at Argonne National Laboratory (ANL).

Tsinghua University provincial-level lifecycle study finds fuel-cycle criteria pollutants of EVs in China could be up to 5x those of natural gas vehicles due to China’s coal-dominant power mix

Green Car Congress

In regions where the share of coal-based electricity is relatively low, EVs can achieve substantial GHG reduction, the team reports in a paper in the ACS journal Environmental Science & Technology. According to the 12 th Five-Year Plan of the China Coal Industry (2011?2015)

Opinion: Why Buffett Bet A Billion On Solar: Miles Per Acre Per Year

Green Car Congress

During the late innings of the ICE-age (as in the Internal Combustion Engine age) it has become clear that feeding gasoline and diesel to the next billion new cars is not going to be easy, or cheap. The cost to operate an EV, per mile, is already well below the cost to drive a standard ICE-age model, and the advantage is likely to widen.

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. Light-duty vehicle miles traveled increases by 20% in the Reference case, growing from 2.9 trillion miles in 2018 to 3.5
