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

Green Car Congress

by Michael Sivak, Sivak Applied Research The overall advantage of battery electric over gasoline vehicles, in terms of well-to-wheels emissions of greenhouse gases, has been well documented. However, the emissions of electric vehicles depend greatly on the energy source used to generate the electricity that powers them.

The Case for Nuclear Cargo Ships

Cars That Think

Nearly all of the world’s ship fleet still runs on diesel fuel, with about a quarter of new ships on order being built to run on somewhat lower-carbon alternatives like liquefied natural gas, methanol, or hybrid propulsion. Shipping uses over 300 million tonnes of fossil fuels every year, producing 3 percent of greenhouse gas emissions.

EIA releases report on CO2 emissions by state; California led in 2010 with transportation-sector emissions

Green Car Congress

For example, some states are located near abundant hydroelectric supplies, while others contain abundant coal resources. To the extent that fuels are used in one state to generate electricity that is consumed in another state, emissions are attributed to the former rather than the latter.

OriginOil, Carbon Sciences Apply for DOE Grants for CO2 to Fuels

Green Car Congress

The consortium includes the Idaho National Laboratory of the Department of Energy (DOE), two top US universities, and materials technology firm Media & Process Technology. Plants with electric power output greater than 50% of total energy output that operate on more than 55% coal as a feedstock are ineligible.

Sandia progressing to demo stage with supercritical CO2 Brayton-cycle turbines; up to 50% increase in efficiency of thermal-to-electric conversion

Green Car Congress

Research focuses on supercritical carbon dioxide (S-CO 2 ) Brayton-cycle turbines, which typically would be used for bulk thermal and nuclear generation of electricity, including next-generation power reactors. The Brayton cycle could yield 20 MW of electricity from a package with a volume as small as four cubic meters.

California Air Resources Board Pushes for Restoration of DOE Funding for Hydrogen Fuel Cell Vehicles; Tackles the Four Miracles

Green Car Congress

In ARB’s analysis, most vehicles on the road in 2050 will need to be electric drive, or ultra low-carbon fuel vehicles—i.e., electricity or hydrogen—by 2050 in order to achieve the required 80% reduction in greenhouse gases.
