Bio Fuels
Slide 12
What are bio fuels? Bio fuels are fuels made from recently
living organisms. They can be divided into three categories:
First-generation, second generation and third generation bio fuels
First-generation bio fuels are made largely from edible sugars and
starches. Second-generation bio fuels are made from non- edible
plant materials. Third-generation bio fuels are made from algae and
other microbes.
Slide 13
First generation bio fuels refer to the fuels that have been
derived from sources like starch, sugar, animal fats and vegetable
oil. The oil is obtained using the conventional techniques of
production. Some of the most popular types of first generation bio
fuels are: Vegetable Oil Bio gas Bio alcohol Syngas
Slide 14
Biodiesel Most common type of bio fuel, used in European
countries very commonly. Biodiesel is produced by a process called
Transesterifcation.
Slide 15
2 nd generation bio fuels Non-food bio-feedstocks are
considered as feedstock for second generation biodiesel. Energy
crops such as jatropha represent the second generation biodiesel
feedstock. Either by using standard transesterification method, or
by using technologies such as biomass to liquid (BTL), such
feedstock could be converted to biodiesel
Slide 16
Biomass Sunlight causes plants to grow and capture carbon
dioxide. The organic matter that makes up those plants is known as
biomass. The use of biomass for any of these purposes is called
biomass energy. The second major source of deriving biomass energy
is from the solid waste.biomass energy This solid waste is either
provided by municipality waste or industrial waste.
Slide 17
Third Generation Bio Fuels
Slide 18
Algae Fuel Growing algae has potential for algae oil production
due to its fast growth rate and the high oil content of some
varieties.
Slide 19
Third Generation Bio Fuels Algae Biodiesel production and algae
oil harvesting systems that work in a efficient manner (Use energy
conservatively) for growing algae and harvesting algae into Algae
biofuels will be the new and long lasting answer to our question of
"World How do we reduce our dependence on fossil fuels

Consume Less Every day U.S. Generates 4.5 million disposable
pens 5.5 million disposable razors 50 million disposable diapers
Consumes 500 million pounds of paper products
Slide 22
U.S. Production Produces 37,000 cars 25,000 hotdogs 30,000
pairs of aerobic shoes million golf balls
Slide 23
Waste Only recycles 25% of paper products 10% glass jars and
bottles EVERY person creates 3.5 pounds of waste per day
Slide 24
What you can do to consume less Double sided printing Scratch
pads Use spell check before printing Rent equipment
Slide 25
What You Can Recycle Office paper, envelopes, stapled booklets,
newspapers, flyers, cardboard boxes Hazardous materials Batteries
Used oil Light bulbs

Future Renewable Sources
Slide 30
Kinetic Energy This is energy created by motion Self powered
gyms create energy from the resistance of stationary bikes and is
sent back into the gyms power grid A nightclub in the Netherlands
installed a kinetic energy dance floor video example
Slide 31
Converting Waste Heat to Electricity An example: The excess hot
water in your shower would be converted into electricity through a
small thermoelectricity device to then fuel your air conditioning.

Slide 32
Solar Chargers Perhaps the most attainable new energy savvy
technology Solar chargers are can now be found in almost any store
with a tech department Costs range from $40-$400
Slide 33
Wave Energy Wave energy is a new technology on the brink of
success. The energy is created by the natural up and down movements
of the waves This also has been used with tides. For example the
Bay of Fundy in Canada. how it works video
Slide 34
Geothermal Energy This is thermal energy stored and generated
in the earth. The energy originates from the original formation of
the planet and from radioactive decay of minerals. According to
UCSUSA.org, the amount of heat within 33,000 feet of earths surface
contains 50,000 times more energy than all the oil and natural gas
found in the world.
