Energy (Second Edition), Gordon Aubrecht
Lab materials will be distributed
Questions
How do we “know” our environment-“scientifically” or otherwise?
What is energy?
What are its various forms and how do they relate to each other?
Can we do without it?
Why is understanding it important for effective dealing with our environment?
Where does it come from?
How much is available to us?
Where does it all go to?
Can we improve the dependability of our energy supplies?
What are our responsibilities to our future with respect to energy?
The Class
The class will be run as a combination of lecture and discussion, with
emphasis on the latter! Productive discussion requires that you have
read (and thought about!) the appropriate text materials (“LM” for Lab
Manual and “H” for Handout) before class. The discussions are intended
to help you understand the text materials and their implications.
If you haven’t read the materials before the class, you won’t be able to
participate in the discussion-making for a very dull class! Also,
you will not be able to ask questions appropriately about the reading materials,
which you have not understood. Since the exams will cover both class
and text material, it would be wise to participate actively and attentively
in all class sessions as well as to do all of the reading carefully.
Besides, discussing this material should be fun and how can you discuss
it if you all have not read the same stuff? “Interactive Question
Papers” (IQ’s) to stimulate discussion will be distributed for each class
via the class Webpage, as will exam hints and homework answers.

Summary
Student Energy Projects
Do one of these four projects as your final exam. Do at most two of the remaining Exercises for Extra Credit . The written reports (about 5 typewritten pages each) should be handed in on or before Monday, December 6, 1999. They will be discussed during the final week in class.
1.) (Up to 10% Extra Credit)
Using either your own computer or one in the Undergraduate Library, “visit” the Lawrence Berkeley National Laboratory Home Energy Saver at: http://hes.lbl.gov/. Working with the programs you find there (and with other linked sites, if you so desire-explore the web!) estimate the energy and monetary costs of your home, as it is, this year. Then, make some reasonable changes in your home and see how much energy and money you can save. Can/will you really make these changes? Why or why not?
2.) (up to 10% Extra Credit)
Using the library and/or the Web, estimate your current annual energy
and monetary costs of commuting to school. Then suggest some alternative
reasonable commuting models and estimate how much energy and money you
can save. Can/will you really make these changes? Why or why
not?
3.) (Up to 10% Extra Credit)
a.) Estimate, as accurately as you reasonably can, the total amount
of energy, (other than home and school), you will use as an individual,
directly and indirectly, this year.
b.) On this basis, make an estimate of the impact you will make on
the present and future environment.
c.) What other, non-energy impacts will you have?
d.) What changes can you reasonably make in your life style to significantly
diminish your impact upon the environment? Estimate, numerically,
how much less energy use would be attributed to you.
e.) What are the chances-and why-that you can/will actually carry out
these changes?
4.) (Up to 10% Extra Credit)
Using data taken from the roof of Wayne's Physics Building ( see http://hal.physics.wayne.edu
), estimate the total amount of solar energy falling on the puilding in
any one day. What fraction of the estimated cooling or heating
requirements of the building would this solar energy supply? Discuss the
reasonableness of your assumptions and results.
