Wiki:Plug-in electric vehicle
Plug-in cars have several benefits compared to conventional internal combustion engine vehicles. They have lower operating and maintenance costs, and produce little or no local air pollution. They reduce dependence on petroleum and may significantly reduce greenhouse gas emissions, depending on the electricity source, as motors are typically much more efficient than ICE. Plug-in hybrids capture most of these benefits when they are operating in all-electric mode.
