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., Among the findings: Summer surface ozone (O 3 ) decreases in most locations due to widespread reductions of traffic NO x emissions. coal, oil, natural gas, and biomass).

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.

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. Eventually, they’ll add equipment to spray tiny aerosol particles of calcium carbonate, the compound found in limestone, blackboard chalk, and Tums antacids.

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

Results of the study suggest that soot is second only to carbon dioxide in contributing to global warming. Jacobson found that the combination of the two types of soot is the second-leading cause of global warming after carbon dioxide. Soot could be further reduced by converting vehicles to run on renewable electric power.

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

Green Car Congress

The report, “ Environmental Assessment of a Full Electric Transportation Portfolio ”, is based on a projection that by 2050 electricity replaces traditional fuels for approximately half of light- and medium-duty transportation and a significant portion of non-road equipment.

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.
