hybrids that you don't hear much talk about--where is all that electricity going to come from and how will it get to your house?
Hybrids don't have to be plugged in like an all electric car like the Nissan Leaf. The newer plug-in models will run just like the older model if it isn't. They run the gas engine as needed for more power or to recharge the battery.

Prius Plug-in FAQ To charge the Prius Plug-in, you simply plug it into any standard household outlet with a dedicated 15-amp circuit. This produces a full charge in just three hours. If you have installed a dedicated 220V Electric Vehicle Supply Equipment (EVSE) outlet, charging the vehicle only takes 1.5 hours. If you run out of electric charge while driving, don't worry - the vehicle automatically transitions to hybrid mode and runs on the gas engine until you have a chance to recharge.
