EIA: projected US CO2 emissions vary up or down depending on coal and nuclear power plant retirements

Green Car Congress

EIA’s Annual Energy Outlook 2014 (AEO2014) features several accelerated retirements cases that represent conditions leading to additional coal and nuclear plant retirements in order to examine the potential energy market and emissions effects of the loss of this capacity.

Study projects emission impacts of inexpensive, efficient EVs: 36% further reduction in LDV GHG by 2050, or 9% economy-wide

Green Car Congress

A new study by researchers at the University of Colorado at Boulder projects the emission impacts of the widespread introduction of inexpensive and efficient electric vehicles into the US light duty vehicle (LDV) sector. Total NO x , VOCs, and SO 2 emissions are similar in OPT and BAU due to inter-sectoral shifts. Click to enlarge.

Study concludes abundant shale gas is neither climate hero nor villain; need for targeted GHG reduction policy

Green Car Congress

While natural gas can reduce greenhouse emissions when it is substituted for higher-emission energy sources, abundant shale gas is not likely to substantially alter total emissions without policies targeted at greenhouse gas reduction, according to a new study by two researchers at Duke University.
