 ON-LINE Lecture Discussion Requirement of 2 questions: (this topic only)

1. Do one question from the QUES 1 OR 2. You may self select which side of the issue you would like to be on.

2. One question from QUES 4. (worth 4 pts)

3. The third question is (optional or 1 point extra credit) this week, but you might answer QUES. 3,
or use General Questions to ask a general question the Prof or others might answer.

Requirements for the Lecture On-Line Discussion
Method to list references and citations.

Use CHAP 13 as a first resource, but the online sources are also very good.

1. Conservation

 A. Fossil Fuel Energy Reserves

(text p.386-388)

 When will the Oil run out? Gives some information and scenarios about how long oil supplies may last.

Future Scenarios on Oil Supplies

 B. Use less energy and improve efficiencies of existing devices - more energy efficient automobiles? energy efficient furnaces, new types of fluorescent light bulbs, energy efficiency ratings on new appliances.

 Pick one of the following two questions.

QUES. 1: Should oil drilling be permitted in the Arctic National Wildlife Refuge? Some in Congress have tried to pass laws permitting this, but so far unsuccessfully. Currently the energy bill passed by the House has the ANWR oil drilling included. The Senate bill does not have this provision.

Debate - has both yes and no sides.

Oil on Ice - Check out explore the issue - more on no side

ARCTIC NATIONAL WILDLIFE REFUGE -This site supports the YES side. From the home page, check out Background. Also has some 10 top reasons to permit drilling. Also check Native Alaskans that are pro development.

 QUES. 2: Should the US raise CAFE (Corporate Automobile Fuel Efficiency) standards for light trucks and SUVs?

Last year, bills were introduced in the U.S. House (HR 1815) and in the Senate (S 804) that would gradually raise the CAFE standards for light trucks to 27.5 mpg by 2007. The House rejected this part of the energy bill.

 QUES. 3. List some things that you could do in your home to increase efficiency and decrease the use of energy. The ideas should be quite specific and things that you will actually do now or in the near future. List one or two items that you did not know about previously.

 QUES. 4: Each student is required to do ONE of the following alternative energy sources.

First look at the Chemistry Discussion Board to select any that are not already taken. At this time you may reserve a topic and post it after doing the research. Then you may double up and add to the first report. Use the extensive internet sources which follow below.

Report on ALL of the following:
1. The science behind how it works,
2. benefits,
3. drawbacks,
4. environmental effects to secure the resources (where do the materials come from to make the device?),
5. environmental effects during use or pollution or other side effects.

You may not find written or visual info on all of the items, but think about it anyway. Five paragraph brief summaries of each energy source. Do not write a term paper on each. These may appear again as part of the next exam and may serve as a resource.
Solar Houses - Active
Solar Houses - Passive
Solar Power Towers or "farms"
Solar Ponds

Biomass - wood or wastes
Biomass - Ethanol
Geothermal - hot or dry steam
Geothermal - Ground heat pumps
Coal to liquids
Coal gasification
Natural gas alternative reserve sources

Hydrogen - direct
Fuel Cell - cars
Fuel Cell - power plants
Electric cars (may do several of these - include electric battery, hybrid)
