Northwestern/Princeton study explores air quality impacts of aggressive conversion to EVs

Green Car Congress

For example, states in the western US (WUS) generally produce a larger fraction of their electricity from renewable and/or “emission-free” sources (i.e., coal, oil, natural gas, and biomass). Among the findings: Summer surface ozone (O 3 ) decreases in most locations due to widespread reductions of traffic NO x emissions.

Why Schools Should Electrify Their Bus Fleets

Blink Charging

Even with a flurry of activity and available funding, though, only about 1% of school buses in the country are currently electric ( matching the approximate percentage of cars and light duty trucks on the road that are electric ). Here are several reasons for school districts to switch to electric buses.

EPRI-NRDC report finds widespread vehicle electrification and a cleaner grid could lead to substantial cuts in GHG by 2050

Green Car Congress

Widespread adoption of electric transportation, including electrification in the off-road sector, could lead to substantial reductions in greenhouse gas (GHG) emissions and could modestly improve air quality, according to a new analysis released by the Electric Power Research Institute (EPRI) and the Natural Resources Defense Council (NRDC).

New Comprehensive Lifecycle Energy and Emissions Inventory Includes Non-Operational Components; Large Aircraft Can Perform Better than Light Rail

Green Car Congress

Ranges in passenger occupancy can easily change the relative performance of modes, with large aircraft performing better than light rail in some of the areas investigated. Samples of the findings include: Off-peak urban diesel buses has the largest energy consumption and GHG emissions per PKT, followed by the three light-duty vehicles.

Test of Planet-Cooling Scheme Could Start in 2022

Cars That Think

Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below. Even less is understood about the potential risks to people and the environment—could the particles deplete the ozone layer, for example, or significantly alter the weather? cancel the launch.
