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

Green Car Congress

These results indicate that coal and oil are the energy sources leading to most emissions, and that hydro, wind, and nuclear are the energy sources leading to least emissions. On the two extremes, coal and oil result in about 176 times the emissions from hydro.

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

Green Car Congress

These results indicate that coal and oil are the energy sources leading to most emissions, and that hydro, wind, and nuclear are the energy sources leading to least emissions. On the two extremes, coal and oil result in about 176 times the emissions from hydro. Therefore, the data for 2008 are included here as well. from coal.

Tsinghua/Argonne Study Finds That Mass Use of EVs in China Could Result in Higher CO2 and Criteria Pollutant Emissions Than Conventional and Hybrid Gasoline Vehicles Due to Coal-Fired Generation of Electricity

Green Car Congress

The study was published online 24 May in the ACS journal Environmental Science & Technology. The study examined the fuel-cycle CO 2 , SO 2 , and NO x emissions of EVs in China in both current (2008) and future (2030) periods and compared them with those of conventional gasoline vehicles and gasoline hybrids.

Harvard SPH large-scale study links PM2.5 levels below EPA standards with higher death rates

Green Car Congress

A new study by researchers at Harvard T.H. Chan School of Public Health found that death rates among people over 65 are higher in zip codes with more fine particulate air pollution (PM 2.5 ) than in those with lower levels of PM 2.5. The open-access study is published in the journal Environmental Health Perspectives.

Study of lead isotopes provides insight into aerosols transport from Asia to US

Green Car Congress

In a first-of-its-kind study, scientists from the US Department of Energy’s Lawrence Berkeley National Laboratory and the California Air Resources Board tracked variations in the amount of lead transported across the Pacific over time. Lead’s geographical diversity was elucidated in a study conducted a decade ago by Australian scientists.

Researchers identify new nitrated PAH compounds from combustion that are hundreds of times more mutagenic than parent PAHs

Green Car Congress

These new compounds were not previously known to exist, and raise additional concerns about the health impacts of heavily-polluted urban air or dietary exposure. PAHs form naturally as the result of almost any type of combustion, from a wood stove to an automobile engine, cigarette or a coal-fired power plant. Staci Simonich.
