What Are Plug-ins?
In an all-electric car, high performance batteries store cleaner, cheaper, domestically produced electricity, and an electric motor provides propulsion with zero emissions. In a plug-in hybrid, more batteries than a conventional hybrid allow local all-electric, zero-emission driving with an internal combustion engine for longer distances.

Electric cars are very reliable. No oil changes, no tune ups. EVs have fewer than 1/10th as many parts as a gas car.  There's no engine, transmission, spark plugs, valves, fuel tank, tailpipe, distributor, starter, clutch, muffler or catalytic converter.

The best way to reduce carbon emissions is to utilize the ever cleaner, greener, more renewable grid to power transportation. Only grid-rechargeable cars can attain the end goal of zero-emissions and ensure fuel price stability.
