Slide 15
The Corporate Average Fuel Economy (CAF) Regulations initiated
by Congress in 1975 Intended to improve the average fuel economy of
cars and light trucks It is the mpg of cars and light trucks that
dont go over 8,500 pounds The standard for passenger cars is 27.5
mpg and the standard for SUVs and light trucks is 22.2 mpg In 2011
the standard will change to include larger vehicles When first
enacted the fuel economy dramatically increased then quickly
declined back down again but as of recently it has started to
slowly improve once more The standards have not changed since the
1980s
Slide 16
Electric Cars An electric motor is used in place of a gas
powered engine. The motor is in turn powered by a controller which
draws its energy from rechargeable, electric batteries. Cut
pollution emissions up to 50% compared to gasoline powered cars
Most argue that they use energy more efficiently One con is that
when electric cars crash the batteries can get wired, a risk that
some consider heavier than the benefits Require a long time to
recharge and there are few places beside home where cars can be
charged Can have high repair cost Are quieter than other cars
Hybrid Cars Most feature ISGs Cut emission rates by up to 35%
One con is there is not an efficient/safe way to dispose of the
batteries and motors The metal materials used in the batteries and
motors are rare and can cause environmental degradation to access
There are government tax breaks if you buy a hybrid They run half
and half on energy from electric and gas Typical 8 year warranty
for the vehicle system Tend to be more costly than average gasoline
powered cars Quieter than average cars Save more money on gas
Factories creating hybrid cars can create as much or more pollution
as factories creating gasoline powered cars Gas engine can help
recharge electric battery while driving and if needed can switch
over
Slide 19
Plug-In Hybrid Cars Runs on gasoline and electricity like
regular hybrid cars but has specific modifications: Larger battery
packs which can be recharged using common household electricity Can
drive very long distances without using any gasoline at all Can run
on biofuel which helps reduce its use of gas It is not possible for
an individual consumer to buy one but they are in the testing
stage

Slide 22
Will save $52 billion per year in fuel costs Already has more
than 100 hybrids in operation 7,200 trucks already 15% fuel
efficient Keeps driver warm without keeping the engine on Trucks
now average about 7 mpg with 80,000 pound load Promises to double
fuel efficiency of trucks from 6.5 to 13 mpgs by 2015 The changes
help to keep 26 billion pounds of carbon dioxide out of the air by
2020 http://www.greencarcongress.com/2005/12/walmart_seeks_t.htm l

Nissan Leaf First affordable car that claims to have 0
emissions and is 100% electric Due to be released by the end of
this year It runs on laminated compact lithium-ion batteries It can
seat up to 5 adults and has a 100 mile range 80% of its battery can
be charged in as little as 30 minutes Has LED headlights that only
consume 10% power of that of traditional lamps It claims to get 367
miles a gallon

Slide 24
Chevrolet Volt It has a 40 mile range It is going to be
launched in November of this year It can run efficiently without
being plugged in for days but gets top performance when charged
everyday Takes 8 hours to fully charge when using a normal outlet
Can charge in as little as 3 hours when a 240v outlet is used
