ALTERNATIVE FUEL & THEIR USES

INTRODUCTION

The increase in energy consumption particularly in the past several decade has raised fears of exhausting vital natural resources

Rapid industrialization and massive growth in population has increased the dependence and use of natural fuels

Approximately 90% of our energy requirement are met by fossil fuels

Studies suggest that if exploited at the same rate, the coal reserves will deplete in the next 200-300 years and petroleum deposits will deplete in the next few decades.

So, it is important for us to engage in research and development of alternative fuels s we may not face scarcity of natural resources in the future.

Alternative Fuel Sources Hydrogen

Biodiesel

Ethanol

Biomass

Hydrogen

Clean source of fuel

Extracted by electrolysis of H2O

Helps lower CO2 emissions

End product is H2O

Uses

Widely used for rocket engines

Used in Internal Combustion Engines when mixed with natural gas Used extensively in fuel cells

Biodiesel

Clean burning alternative fuel source

Derived from Soy beans and animal fats

Has same vehicular performance as Diesel

Completely renewable fuel source

Uses

Popularly used in vehicles and power generators

Ethanol

Is a renewable energy source

Can be produced from variety of feedstock such as sugar cane , potatoes , sweet potatoes , molasses , corn , etc.

Mostly produced by Fermentation

Is a particulate _ free burning fuel source

Uses

Most commonly used to power automobiles

Additive for gasoline

Biomass Is the most important

source for energy productions supplied by agriculture Is a “carbon lean’’ fuel producing a fraction of the Carbon emissions of fossil Anaerobic digestions converts biomass, especially waste product such as municipal solid waste and market waste

Uses

Can offer local business opportunities and support the rural economy

Can be used as a domestic fuel

Used for boilers

Conclusion

The alternative fuel sources are environment friendly as compare to fossil fuels.

By using alternative sources we can reduce Air pollution , which is cause of many deadly diseases.

Using alternative fuel helps diminish Global Warming.

Throughout the year these sources are available without affecting the Environment.

Helps conserve natural resources.
