1. Time for an energy boost!
Please get out objectives #16 and 17 for a stamp.
Also, please have your ANWR summary out for a stamp.
RTB!

2. Quiz reflection/objective check

3. #7
Nonrenewable – longer than a human lifetime to form.
Fossil Fuels are nonrenewable because they take millions of years to form.
(If we use trees faster than they are growing, they are still a renewable resource)

4. #8 Because fossil fuels contain hydrocarbons with lots of bonds
NUMBER OF BONDS (not the length or the strength of bonds)

5. #9
US natural gas production peaked in 1973 until fracking really started in 2005.
US production has increased 10 times
DOE – unproven resources of shale gas = about 500 trillion cubic feet

6. Check your ANWR summary
Compare with your neighbor and highlight similar concepts.
Make sure you have the big ideas:
Where
Issue being debated
Parties/groups involved

7. ANWR: Arctic National Wildlife Refuge – 5 min summary!

10. National Petroleum Reserve in Alaska
 Technically recoverable, undiscovered oil billion barrels.
An estimated 1.3 to 5.6 billion barrels of those technically recoverable oil resources is economically recoverable at market prices of $22 to $30 per barrel.
Technically recoverable, natural gas for the same area trillion cubic feet. - USGS, 2002

17. Rank the arguments For your given position,
Write one argument to support your side on each board.
Put them in order from strongest argument to weakest.
Be ready to defend your choices.

18. Add to your summary (and label it objective #24)

19. A proposition:
We NEED energy. The FORM of energy and the FUELS we use to create convenient energy are a matter of choice.

20. Evaluating energy sources should include net energy
Net energy is the energy provided by the resource (fuel) minus the energy required to produce the fuel.

21. The limitations (or opportunities) of physics
Potential Energy
Position
Chemical bonds
Kinetic Energy
Heat (molecules)
Light (photons)
Motion/mechanical
Electrical (electrons)
Thermodynamics #1 – energy is neither created or destroyed, it just changes form.
Thermodynamics #2 – every time energy changes form, some is lost to the surrounding environment; energy generally becomes less organized as it changes form.

22. How many energy conversions to create natural gas?

23. Unconventional fuels have lower net energy (tar sands and oil shales)

24. Tar sands contain bitumen

25. Tar sands extraction Mining Steam injection Refining
Requires significantly more energy than petroleum extraction

26. A proposition:
We NEED energy. The FORM of energy and the FUELS we use to create convenient energy are a matter of choice.
