The hybrid news continues to flood in this week. On Tuesday, we learned of Wal-Mart's
new hybrid addition to its trucking fleet, then New York City Mayor Michael
Bloomberg announced the city's decision to make all yellow cabs hybrid by 2012.
Today, UPS announced that it is adding 50 hybrid electric vehicles (HEVs) to
its delivery fleet in Atlanta, Dallas, Houston and Phoenix.
The stop and go nature of deliveries to commercial and
residential addresses make hybrid technology a perfect fit for UPS trucks.
Hybrid vehicles are most efficient in stop-and-go city traffic where the
electric motor can be called upon to handle a majority of the propulsion
"We're excited to be among the first to deploy the
latest in HEV technology because it promises a 45% increase in fuel economy in
addition to a dramatic decrease in vehicle emissions," said Robert Hall,
Director of UPS Ground Fleet Engineering.
UPS says that the 50 new HEVs improve fuel efficiency by 45 percent, will save the company 44,000
gallons of fuel per year and reduce carbon emissions by 457 metric tons per
The HEV trucks feature a smaller capacity diesel
engine, lithium-ion battery pack and an electric motor/generator. Regenerative
braking is also used to capture energy normally lost with
conventional brakes and converts it to charge the onboard battery pack. The
hybrid system being used is from Eaton Corporation -- the same company that
provides hybrid power for Wal-Mart's new Peterbilt Model 386 Hybrid.
UPS' new HEV trucks look nearly identical to the
existing "brownies" that can be seen scurrying through city streets.
What will tip you off to their hybrid functionality are "Low Emission,
Hybrid Electric Vehicle" scripting on the side of the truck and an overall
UPS currently operates over 20,000 low-emission and
alternative-fuel vehicles in the United States.
quote: Creathir, they wouldn't do it unless it were to save them money. I won't make the big corporations like Walmart and UPS look evil, because they, like any responsible corporation, do care about the environment. But, adding 50 vehicles is a bold move that would only happen if it were to cut their bottom line.
quote: As to Walmart doing "just one", that one was something like 0.5% of their fleet as I recall, and that's probably a LOT bigger percentage than these UPS trucks are in UPS's total fleet. With UPS it'd make no sense to just trial one unit because it'd be too expensive. UPS trucks are unique custom vehicles so having just one made would be very very expensive on a per-truck basis.

quote: The WindHunter is the concept of an offshore, floating system of wind turbines that make electricity, electrolyze sea water, and make hydrogen. The architects of the idea envision four two-megawatt wind turbines mounted on a moveable framework connected to the deck of a ship. The electricity produced from the turbines is sent to four electrolyzers in the hulls or inside the deck, and then the collected hydrogen is compressed and stored in tube tank trailers until transported to shore. From the website: “This continuously manned, safe and stable system will be easily maintained on-board while relocating to the best wind conditions for the wind turbines…. These large ships or platforms will operate out of sight of land either moored or anchored while facing into the wind and the oncoming waves. Millions of them can operate on the world's oceans with minimal environmental impact and human resistance.”

quote: Honda and Toyota don't have such a large stake in the oil industry so they will be more likely to release hybrids and then all electric/hydrogen/whatever vehicles.
quote: Your absolutely right, The domestic automakers are definitely the only oil lapdogs and are making a killing right now on the high oil prices.
