Learning Targets
I can convert between kWh, therms, BTUs, gallons of fuel, and lbs. of CO2
I can compare energy usage statistics at the local, state and national level and hypothesize reasons for the differences.
Classroom Heating Lab
Use your data on window square footage and temp. to complete the classroom heating lab in your lab book.
Do everything but the extension
Energy Usage Statistics
Find the document on my website called “Examining our Current Energy Status”
Complete and submit to me as a Google doc. This is due Tuesday, along with Module 35 notes and end of SECTION multiple choice.
Unit 7 Test- Farming and Land Use
Mult Choice (out of 40)A = 36-40B = 32-35C = 28-31D = 24-27Retakes for 27 and below Q’s dropped: 3 and 32 (test A)13 and 16 (test B)
FRQ (out of 10) BTW, a 1.5
multiplier was added in the gradebook, so the FRQ is out of 15
Unit 7 Test Corrections- Mult. Choice
This time- don’t correct each one. Find and record the major concept or key term you missed
associated with that question. Resolve parts of the FRQ you missed.
Need to retake it? Please do that by next Friday afternoon!

How Did We Get Here?
Industrial Revolution
Exponential Growth
Energy Crisis
Energy Crisis
Pre 1970 - Oil was relatively plentiful and cheap Formation of OPEC – started in 1960 Countries currently in OPEC: Algeria, Angola, Ecuador,
Iran, Iraq, Kuwait, Libya, Nigeria, Qatar, Saudi Arabia, the United Arab Emirates, and Venezuela
Account for 79% of world reserves & 44% of world production
Goals: Safeguarding interests by setting the price of a barrel of oil ensuring stable supply and demand in int’l oil markets
Events of the 1970’s
Arab members of OPEC refuse to ship oil to the U.S. and most of Western Europe (1973) Wanted countries to stop supporting Israel in
Yom Kippur War with Syria & Egypt U.S. was using cheap oil to make other
products (particularly plastics) and selling them back to OPEC countries at much higher rates. (Sometimes 300% inflation)
Revolution in Iran slows production (1979)
Consequences
Petroleum prices quadruple Schools close in the winter for lack of
heating oil Manufacturing plants close or lay people
off Increased interest in alternative energies Global recession
Establishment of Strategic Petroleum Reserves in 1975
Emergency supply of crude oil in salt caverns along the Gulf of Mexico
Currently holds around 1 billion gallons of oil
Approximate 57 day supply
National Petroleum Reserve Formalized in 1976 Largest area of
undisturbed wilderness in U.S.
Approximately 896 million barrels of oil
Development started in 1990’s
Disagreements with Inupiat’s & env. groups – lots of lawsuits
Bureau of Land Management just decided to allow oil production (2/2015)
ANWR
Energy Conservation TOPIC OUTLINE V.F
Two Choices …
Use less through personal choices OR Increase efficiency of use http://seattletimes.nwsource.com/html/businesstechnology/2014715242_facebookse
rver08.html
Both of these peaked in the late 1970’s, steeply dropped in the 1990’s and haven’t risen much since then
National Appliance Energy Conservation Act - 1987
Set minimum energy efficiency requirements on appliances Eventually led to formation of Energy Star
Voluntary program to build factories, office buildings, houses, and appliances that exceed these standards

Incandescent vs. Compact Fluorescent
Easy bake ovens and incandescent light bulbs
http://www.msnbc.msn.com/id/3032619/ns/nightly_news/#41768619
http://www.nytimes.com/2009/09/01/business/energy-environment/01iht-bulb.html
75% of the energy that goes into an incandescent is lost as heat and is not used for light
Next new light – LED’s http://www.msnbc.msn.com/id/3032619/ns/NBCNightlyNews/#44034437
What is saved besides electricity by using a compact fluorescent?
GHG’s, Air Pollution, Mining costs, Landfill space
If each household switched out one incandescant for a compact fluorescent the energy saved would be approximately equal to taking 1 million cars off the road
Areas targeted by efficiency improvements
Window on the right is an energy star window in winter
1) Insulation2) Windows3) Tight
construction/caulking
4) Heating/cooling systems
5) Appliances
Cogeneration - capture and reuse “waste” heat
CAFE Standards – Corporate Average Fuel Efficiency
Federal Standards for MPG in cars & trucks
2007 model year CAFE standard for cars was 27.5 mpg and light trucks 22.2 mpg (SUV’s are excempt as they are classified as heavy trucks/farm vehicles)
Many companies did not meet this standard and paid fines
Why would they make this choice?
By 2020 35 mpg
Hybrids and Electric Cars Hybrids use a combination of gas, generators, and batteries Electric cars – use electricity to charge a battery Seattle was chosen as a test city for the Nissan leaf – Why? http://www.seattlepi.com/transportation/416374_leaf9.html
