Carbon emissions from generating electricity for electric vehicles vary greatly across the individual US states

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. Energy source Proportional amount of emissions relative to hydro Coal 175.9

MIT researchers build model simulating atmospheric transport of PAHs; how chemicals get to the Arctic

Green Car Congress

Selin and Friedman use the global 3-D chemical transport model GEOS-Chem to track the day-to-day transport of PAHs—toxic byproducts of burning wood, coal, oil and other forms of energy that remain in the atmosphere for less time than other persistent organic pollutants regulated by global standards.

CMU/DAI study finds shutting down US nuclear plants would have significant negative economic and environmental consequences

Green Car Congress

Shifting from nuclear to other types of power plants could affect the reliability of the electricity supply, electricity costs, air pollution, carbon emissions, and the reliance on fossil fuels such as coal and natural gas, the researchers said. The calculated cost of generation with the new mix of plants was a lower bound.

Perspective: Regional Greenhouse Gas Cap-and-Trade Programs May be the Solution

Green Car Congress

Cap-and-trade was first tried on a significant scale twenty years ago under the first Bush administration as a way to address the problem of airborne sulfur dioxide pollution–widely known as acid rain–from coal-burning power plants in the eastern United States. greenhouse gas emissions.
