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

Slide 21

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. Laundromat

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.
