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.

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? about 0.6 °C.

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

Soot—black and brown particles that absorb solar radiation—comes from two types of sources: fossil fuels such as diesel, coal, gasoline, jet fuel; and solid biofuels such as wood, manure, dung, and other solid biomass used for home heating and cooking around the world. Jacobson is a senior fellow at the Woods Institute for the Environment.

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. Ozone concentration increases were modeled for small areas near central Denver.
