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)

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
