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.

Plug-in Hybrid Study: Electricity Better

Plugs and Cars

UCS advocates relentlessly for cleaner gasoline vehicles and dismisses plug-ins of all sorts, the Sierra Club strikes deals with Ford to promote a few thousand gasoline-dependent hybrids in exchange for advertising dollars, and the NRDC jumped on the biofuels bandwagon just as the cost of corn ethanol became impossible to ignore.

Perspective: US Needs to Transition to Hydrous Ethanol as the Primary Renewable Transportation Fuel

Green Car Congress

In 1975, General Ernesto Geisel, then-president of Brazil, ordered the country’s gasoline supply mixed with 10% ethanol. The level was raised to 25% over the next five years, which was intended to maintain a constant Brazilian gasoline supply for an ever-increasing demand. These were arguably the first flex-fuel vehicles.
