Gov. Jerry Brown appears at the United Parcel Service facility in West Sacramento on Tuesday for the debut of its new delivery fleet. The all-electric, zero-emissions trucks are expected to reduce fuel consumption by 126,000 gallons a year. When a driver applies the brakes on one of the new trucks, the energy is stored and recycled back into the vehicle's battery.
