Texas study finds PHEV use could increase ozone at night, decrease ozone during the day

Green Car Congress

A study by researchers at the University of Texas found that in general, use of plug-in hybrid electric vehicles (PHEVs) can lead to an increase in ozone during nighttime hours (due to decreased scavenging from both vehicles and EGU stacks) and a decrease in ozone during daytime hours.

HEI launches two new non-tailpipe particulate emission studies

Green Car Congress

Emissions from automobile exhaust systems have decreased in recent years due to the introduction of cleaner fuels and new control technologies on internal combustion engines, as well as increases in numbers of hybrid and electric vehicles. 10 ) of urban air, a fraction known to be enriched with non-tailpipe constituents.

Why Schools Should Electrify Their Bus Fleets

Blink Charging

The transition away from gasoline and diesel vehicles to electric vehicles (EVs) is going full throttle in the United States, and that includes the iconic yellow school bus. Here are several reasons for school districts to switch to electric buses.

Study Finds Controlling Soot May Be Fastest Method to Reduce Arctic Ice Loss and Global Warming; Second-Leading Cause of Global Warming After CO2

Green Car Congress

Jacobson used a computer model of global climate, air pollution and weather that he developed over the last 20 years and updated to include additional atmospheric processes to analyze how soot can heat clouds, snow and ice. Soot could be further reduced by converting vehicles to run on renewable electric power. Dessler et al.,

Modelling the Impact of PHEVs on Ozone in Denver

Green Car Congress

Researchers at the University of Colorado, Boulder and the National Renewable Energy Laboratory (NREL) modeled the emissions impact had plug-in hybrid electric vehicles (PHEVs) replaced light duty gasoline vehicles in the Denver, Colorado area in summer 2006. million vehicles and would have increased by 3 tpd from power plants.
