Electric Vehicles Help Drive Climate Action - The White House 19nov2014 Efficient Drivetrains Incorporated and "Pacific Gas & Electric demonstrated their new plug-in hybrid bucket truck — a utility vehicle with emissions nearly 80% lower than a conventional truck. Not only does PG&E’s plug-in hybrid utility vehicle run cleaner, it provides up to 120 kW of exportable power — meaning that the trucks can actually be used to shorten or end power outages by plugging their reserves into the grid."
