Coal-Power Can't Stop Plug-In Hybrids From Beating Normal Cars
As Benjamin reported on EcoGeek last week, even if all plug-in hybrid electric vehicles (PHEVs) were recharged by coal-based electricity, they would still be an improvement over regular cars. Take a look at this graph from Technology Review, who reported that “plug-ins always result in lower emissions than conventional cars.” They beat hybrids too, unless power is coming exclusively from coal:
This is important news, since the authors also estimate that by 2050, 60% of US transportation could be met by plug-in hybrid electric vehicles. Total impact on electrical generation may all depend on when the vehicles are charged. A recent study from Oak Ridge National Laboratory showed that charging vehicles during off-peak hours (after 10 pm) would result in only slight increases in energy draw, while charging them after work could require 160 new power plants over the next few decades.
