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.

DOE: US average EV CO2e/year is 4,815 lbs, vs. 11,435 lbs for average gasoline car

Green Car Congress

Although all-electric vehicles (EVs) produce zero tailpipe emissions, there are upstream emissions of greenhouse gases from electricity production. Using electricity production data by source and state, the DOE’s Alternative Fuels Data Center has estimated the annual carbon dioxide (CO 2 e)-equivalent emissions of a typical EV.

EPA proposes rule for nationwide 30% cut in GHG from existing power plants by 2030 relative to 2005

Green Car Congress

The US Environmental Protection Agency (EPA) released the already widely-discussed (albeit without much detail) “Clean Power Plan” proposal, which mandates a national average 30% cut in greenhouse gas emissions from existing power plants from 2005 levels by 2030. EPA is only proposing goals for states with fossil fuel-fired power plants.

The Great Electric Plane Race. Unlike the national air races of the 1920s, however, the Pulitzer Electric Aircraft Race, scheduled for 19 May, will include only electric-propulsion aircraft. The plant will replace an existing coal-fired plant and generate hydrogen—which can be used in fuel cells—using solar photovoltaics.

How to Prevent Blackouts by Packetizing the Power Grid

Cars That Think

That need for balance is true of electric power grids, too. Spiking demand for electric heat collided with supply problems created by frozen natural-gas equipment and below-average wind-power production. The brown line shows the uncoordinated load from 1,000 electric water heaters for reference. Here’s how.

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.
