The Problem
 Transportation consumes 20% of US
energy and 20% of US CO2 emissions
 Not sustainable for the next 50 years
 “I feel more confident than ever that the
power to save the planet rests with the
individual consumer.”- Denis Hayes
 Consumers can have a positive impact on
the environment
The Solution
 HEVs and Fuel cell technology are




currently the leading solutions compatible
to sustainable development
Both have advantages and disadvantages
Barriers to fuel cell economy
Advantages to HEVs over current Internal
Combustion engines
The current disadvantages to HEVs
Fuel Cell Technology
 Potential solutions to
both HEV and Fuel
Cell Technology
 HEVs, for now, seem
to be the the more
applicable answer
 Many barriers to
overcome with fuel
cell technology
Barriers to fuel cell technology
 Availability
 Production, especially in the
short run
 Reduction of harmful emissions?
 Expensive
 Infrastructure problems
Advantages of HEVs






Use less oil than ICE
Emit less CO2 than ICE
Fuel efficiency increased
Honda Insight- 700 mi/tank
Toyota Prius- 500 mi/tank
Honda Civic Hybrid- 650 mi/tank

 Less overall mass
 Regenerative braking
 Battery level
efficiency
 Tax incentives

In the next 5 years…
 Growing demand
 Greater market
 Car companies will
respond
 More variety
Conclusion
 Air pollution is a
serious concern
 Fallbacks to Fuel Cell
economy
 In the short run HEVs
seem to be a viable
alternative
