Importance: Energy is used by us every day,all day and comes in many forms. Thenatural resources of the world are depleting

day by dayThe United States and other highlydeveloped societies are in serious troublewhen it comes to consuming the worlds

natural, non-renewable energy resources.Scientists and technologists must act now tounderstand and develop alternativerenewable energy sources.

THE NEED FOR ALTERNATIVERENEWABLE ENERGY

Types of hybrid systems:

+arallel% ,ses fuel for the gas

engine and batteriesfor the electric motor.

Both electric motorand gas engineconnect totransmission.

Both !ower sources

can !ower thetransmissionsimultaneously orindividually.

All !lants store energy inside themselves asa result of !hotosynthesis.

Biomass fuels utilie the energy stored in

living matter to !rovide energy for homesand automobiles. Biomass fuels include wood wood waste straw

manure sugar cane and many other by!roductsfrom a variety of agricultural !rocesses.

Biomass

Hydrogen Fuel Cell Vehicle

3t is the )evice in which Hydrogen ando$ygen are combined to !roducechemical energy that is converted

directly into electrical energy thatenergy is then used to !ower the vehicles

electric motors.
