The document discusses the increasing reliance on fossil fuels for energy needs and the finite nature of these resources. It states that approximately 90% of energy requirements are met by fossil fuels like coal and petroleum, which are expected to deplete within the next 200-300 years and few decades respectively. To avoid future scarcity, the document emphasizes the need to develop alternative renewable energy sources like hydrogen, biodiesel, ethanol, and biomass, which are more environmentally friendly and sustainable than fossil fuels.

2.  The increase in energy consumption
particularly in the past several decades has
raised fears of exhausting vital natural
resources
 Rapidindustrialization and massive growth in
population has increased the dependence and
use of natural fuels
 Approximately90% of our energy
requirement are met by fossil fuels

3.  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
so we may not face scarcity of natural
resources in the future

4.  Hydrogen
 Biodiesel
 Ethanol
 Biomass

5.  Clean source of fuel
 Extracted by electrolysis of H2O
 Helps lower CO2 emissions
 End product is H2O

6.  Widely used for Rocket Engines
 Used
for Internal Combustion Engines when
mixed with natural gas
 Used extensively in fuel cells

7.  Clean burning alternative fuel source
 Derived from Soy beans and animal fats
 Has same vehicular performance as Diesel
 Completely renewable fuel source

8.  Popularly
used in vehicles and power
generators

9.  Is a renewable energy source
 canbe produced from a variety of feedstock
such as sugar cane, potatoes, sweet potatoes,
molasses, corn, etc.
 Mostly produced by Fermentation
 Is a particulate-free burning fuel source

10.  Most commonly used to power automobiles
 Additive for gasoline

11.  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 digestion converts biomass,
especially waste product such as municipal
solid waste and market waste.

12.  Canoffer local business opportunities and
support the rural economy
 Can be used as a domestic fuel
 Used for boilers

13.  The alternative fuel sources are environment-
friendly as opposed to fossil fuels
 Byusing alternative sources we can reduce,
Air pollution, soil pollution and water
pollution
 Using
alternative fuel helps diminish Global
Warming

14.  Due to technological advancements vehicles
are made with improved fuel efficiency and
also perfect hybrid vehicle are available
 Throughout the year these sources are
available without affecting the Environment
 Helps conserve natural resources
