CMU county-level study shows plug-ins have larger or smaller lifecycle GHG than gasoline ICE depending on regional factors

Green Car Congress

Jeremy Michalek accounted for regional differences in emissions due to marginal grid mix; ambient temperature; patterns of vehicle miles traveled (VMT); and driving conditions (city versus highway). They used energy consumption and VMT patterns to compute timing and duration of vehicle charging.

Why the Next Microgrids Will Be Well Connected

Cars That Think

A microgrid is like a miniaturized, tightly controlled version of a power grid. Such networked microgrids can be isolated for longer periods from the main grid, which is crucial during long-term outages caused by severe weather and other natural disasters. How can a microgrid help after a power outage? percent to 2.8 percent.

Researchers find Nissan LEAF creates less CO2 than Toyota Prius hybrid in west US and Texas, but more in N. Midwest

Green Car Congress

Regionally specific lifecycle CO 2 emissions per mile traveled for plug-in hybrid electric vehicles (PHEVs) and battery electric vehicles (BEVs) in the US can vary widely based on grid emission factors (i.e., Among the findings were that: delayed charging (i.e., Among the findings were that: delayed charging (i.e.,

A closer look at minimizing AC charging losses: From the breaker to EV (Part 1)

Charged EVs

In the quest to improve efficiency even more, the focus tends to be on the flashier parts of the drivetrain, like the motor (which certainly deserves it) and inverter (which arguably doesn’t, since efficiency is typically already ~99 %), while scant attention is paid to relatively unsexy things like charging cables and auxiliary/parasitic loads.

MIT Battery Breakthrough Could Revolutionize Electric Cars : Gas 2.0

Tony Karrer Delicious EVdriven

The breakthrough could revolutionize electric car battery technology and pave the way for ultra-fast charging electric vehicles in as little as two years. When the team tested the newly-coated cathode, they discovered it could be charged and discharged in as little as 9 seconds. by RSS or sign up by email. Herron makes a valid point.

Solar Smackdown in Torrance – Installer Sues City on Behalf of the Sun

Creative Greenius

I went and spoke to their City Council and said “For $50,000 a house I’ll put in solar AND battery systems and take you off the grid. If you’re going to do it, take the homes off the grid. That’s pretty mean to the rest of the grid. And now Gainesville, Florida has a real estate boom going on only it’s for roofs and not ground.
