Which is more efficient from a Complete Life Cycle Perspective?
The Jeep Grand Cherokee or the Toyota Prius?

The Grand Cherokee is more efficient than the Toyota Prius!!

                                                             Grand Cherokee:

Why did the Prius Receive a Lower Rating than the Cherokee?
The 15,000 mile battery commute…..

   •Prius has two engines – a conventional gas engine and an electric motor.

   •The Prius battery is made of nickel which is mined in Sudbury, Canada
       (Sudbury is so polluted it is used by NASA to simulate the moon)

   •The nickel is smelted at the Nickel Center near Georgian Bay, Canada.

   •Then it’s shipped to Europe for refinement in Wales.

   •Then it’s shipped to China for further processing into nickel foam.

   •Then it’s shipped to Japan where the batteries are manufactured.

   •Finally the completed cars are shipped back to North America for sale.

     What was the most energy efficient car in the study?
Winner – The Smart Car

Life Cycle Rating of 0.583
 Why the Smart Car?

                      •Lightweight steel unibody

                      •Plastic Body Panels that
                      can be easily replaced

  How about Electric Vehicles….?
  Cradle to Grave CO2 Emissions – Gas / Hybrid / Electric

  Study conducted in 2003
  by the Institute for
  Lifecycle Environmental

Total carbon dioxide emissions over the lifetimes of gasoline, hybrid, and electric cars.
The electric car is shown three times, with differing use energies depending on the method
of generating electricity: coal, liquefied natural gas, or hydroelectric.
Electric power losses of 7% to 8% during transmission are excluded.

Not so Easy to figure out……
   Determining whether a product is more or less environmentally friendly
   is not a subject that can be evaluated easily. Consumer Marketing
   makes being objective more difficult. It is certainly not as black and
   white as I originally thought. If anything, it taught me that there is still a
   lot of grey in the world of green.

                             Tail Pipe Emissions

In a comparative study conducted by the EPA in 2002, between
conventional diesel fuel and biodiesel, the EPA found biodiesel to cause
less (or more) pollution in the following categories:

         Unburned Hydrocarbons                                            -67%
         Carbon Monoxide                                                  -48%

   A Drop in the Bucket...
   In 2007, the US consumed 317 BILLION gallons of crude oil. 2007 production
   of Biodiesel is projected to be 500 million gallons. That’s only 0.16% of total
   petroleum consumption, and 0.71% of total diesel fuel / heating oil consumption.

Renewable and Sustainable…..
•Made from vegetables, plants and animal fats.

Better for your engine…..
•Biodiesel has inherently better lubricating properties than diesel. Engines run on
 biodiesel last longer.

Less Reliance on Foreign Oil…..
•And less potential money in the hands of terrorists

Significantly less pollution….
•Biodiesel is 10 times LESS toxic than household table salt. If you wanted to, you
 could eat it with no ill effects. It biodegrades faster than sugar.

•Can be used in any conventional diesel engine with no modifications whatsoever.


A Different Shade of Green…..
•Fuel is a commodity. “Break even business” Very dependent on oil prices.
•15 to 20% of the total fuel cost is federal and local taxes.
 Some “biodieselers” have been fined and threatened with imprisonment.

Watch Out for COLD Weather…..
•Biodiesel gels about 32 deg. F (versus -15 for Diesel)

Can only be used in a DIESEL engine…..
•Less than 2% of cars in the US have diesel engines.

Could raise food prices….
•What happened to corn with ethanol could happen to soy or other crops if
virgin oil is taken from the food supply.

Cleaner, but not the cleanest….
•Fuels like hydrogen are better, but not currently practical.
