As states use less coal for electricity, driving electric vehicles becomes even cleaner

Green Car Congress

This brief study analyses, for each individual state, the changes from 2008 to 2018 in the use of coal (one of the two most polluting energy sources) to generate electricity. Oil is used relatively infrequently in the United States as an energy source for electricity.

As states continue to use less coal for electricity, driving electric vehicles becomes even cleaner

Green Car Congress

This brief study analyzes, for each individual state, the changes from 2018 to 2020 in the use of coal (one of the two most polluting energy sources) to generate electricity. Oil is used relatively infrequently in the United States as an energy source for electricity.

Study finds that current approach to limiting wintertime pollution may initially backfire

Green Car Congress

The processes that create ozone pollution in the summer can also trigger the formation of wintertime air pollution, according to a new study from researchers at the University of Colorado Boulder and NOAA, in partnership with the University of Utah. A key control strategy is to reduce emissions of the limiting reagent.

Study finds farms a major source of fine-particulate air pollution

Green Car Congress

Emissions from farms outweigh all other human sources of fine-particulate air pollution in much of the United States, Europe, Russia and China, according a new study published in Geophysical Research Letters , a journal of the American Geophysical Union. micrometers across, about 1/30 the width of a human hair.

Ice core data show why air pollution is dropping more slowly in US and Western Europe despite lower sulfur emissions

Green Car Congress

The air in the United States and Western Europe is much cleaner than even a decade ago. We need to understand this multiphase chemistry in the atmosphere to design an efficient strategy to manage air pollution and accurately predict future air pollution and climate change impacts.

Study: consumer products overtake transportation as largest source of VOCs air pollution in cities

Green Car Congress

Thus, it is important to identify and quantify the most important human-produced sources of VOC emissions to effectively mitigate air pollution and improve human health, the authors said. Automotive emissions of VOCs have decreased steadily from efforts to control tailpipe emissions in the United States and Europe.
