INTRODUCTION METHADOLOGY APPLICATION CONCLUSION

INTRODUCTION FOSSIL FUEL ADVANTAGES• GLOBAL ECONOMY• BASIC REQUIREMENT

DISADVANTAGES• HIGH DEMAND• LESS AVAILABILITY• GLOBAL WARMING

• ALTERNATE FUEL?

ALTERNATE FUEL- BIOFUEL GENERATIONS FIRST-CROPS• SCARCITY OF FOOD• INCRESE IN FOOD PRICE

SECOND-RESIDUES• DECREASE IN ORGANIC MATTER

THIRD-ALGAE• OVERCOMES DRAWBACKS
