    Weekend homework

    Team,
    Please also check on Haiku:
    Three assignments, due 6PM Sunday night: questions, reading and TYC

    e2 video: Growing energy

    1. Google Steve Chu

    what did he get an award for?

    why is this important to the end of this story?


    2. Google Dan Kammen

    on what?

    why does he cite Brazilian sugar ethanol as sustainable?

    compare this with corn ethanol grown in the US (e.g. Nebraska)


    3. Compare sugar ethanol from Brazil with US corn ethanol

    which competes for food?

    which needs petrochemical to fertilize?

    what is the energy balance like for each?

    what is/was bagasse used for?

    what is bagasse made of?

    how did sugar cane mills here in Hawaii fuel their boilers?

    was sugar indigenous, and could it grow here again? explain.


    4. Google Vijay

    5. Oil Embargo

    when did this happen?

    why?

    what happened?

    how did this change the lifestyle of people in the US?

    is this similar to today?


    6. Corn Ethanol

    why is this so prevalent in the US?

    who backs it and why?

    who was president in 2002, when many of the corn ethanol policies began?

    what was his line of work before?

    what about his vice president?


    7. Cars

    why do you think VW has put more research into biofuel cars than hybrids?

    what is a CAFE standard?

    what was made exempt from CAFE standards around 1995?

    what impact did this have on the country?


    8. Cellulosic Ethanol

    what is this?

    how is it different from corn ethanol or sugar ethanol?

    now rethink your bagasse question from above

    why is Steve Chu key to this?

    imagine Brazil with sugar ethanol AND cellulosic ethanol-your thoughts?



    Please read chapter 21 in Withgott 4e here:

    http://physics.hpa.edu/physics/apenvsci/withgott%204e/text/21-renewable%20energy.pdf

    And complete the Testing your comprehension on page 614
