DTF: Diesel dominates commercial truck, transit and school bus fleets in US

Green Car Congress

Other fuels that play a role in commercial trucking include gasoline (23%) and compressed natural gas (0.4%). Electric and other categories each register less than 1%. About 32% of all electric trucks nationwide are in California, where for every electric truck there are about 300 diesel trucks (all years, Classes 3-8).

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.
