Day 2 Plan Recap: 1a, 2a, 3, 4a & 4b #5) Examples of Waste #6) Energy Pie Charts #7) Alternate Energy Systems #8) Careers #2b) Demonstrate Hair Dryer, Solar & Mag Glass #1b) What have you learned? Collect Papers & Sign Blue Cards

Requirement 5 In a notebook, identify and describe FIVE examples of energy waste in your school or community. Suggest in each case possible ways to reduce this waste. Describe the idea of trade-offs in energy use. 5a) Explain how the changes you suggest would lower costs, reduce pollution, or otherwise improve your community. 5b) Explain what changes to routines, habits or convenience are necessary to reduce energy waste. Tell why people might resist the changes you suggest.

Requirement 6 Prepare pie charts showing the following information, and explain to your counselor the important idea each chart reveals. Tell where you got your information. Explain how cost affects the use of a nonrenewable resource and makes alternatives practical.

Requirement 6a The energy resources that supply the United States with most of its energy. http://www.eia.gov/

Requirement 6a - 2014

Requirement 6a-2015

Requirement 6b

Requirement 6c

Requirement 6d-2014

Requirement 6d-2015

Requirement 6e

Requirement 7 Tell what is being done to make FIVE of the following energy systems produce more usable energy. In your explanation, describe the technology, cost, environmental impacts and safety concerns.

7) Biomass or waste to energy plants

7) Combined Heat & Power (CHP) Highly efficient system to provide power & heat with a single fuel input source (generally natural gas) Recovered heat (by-product of fuel combustion) is used for cooling or heating makes CHP systems typically achieve 60/% to 80% in efficiency Facilities can use CHP to produce both electricity and heat on-site instead of obtaining separately electricity from the grid and producing heat from a boiler in a Separate Heat Power (SHP) configuration

Efficiency of CHP vs. SHP 7) Combined Heat & Power (CHP) Efficiency of CHP vs. SHP CHP: combined heat & power, electricity and heat are both generated from on fuel SHP: separate heat & power, electricity is purchased outside & boilers generate heat CHP efficiency: 75% SHP efficiency: 51% An efficiency gain of 24% That yields 32% energy savings Conventional system is SHP

7) Combined Heat & Power (CHP) Emission of CHP vs. SHP CHP: combined heat & power, electricity and heat are both generated from on fuel SHP: separate heat & power, electricity is purchased outside & boilers generate heat CHP emissions: 23kTon/yr SHP emissions: 45 kTon/yr A reduction of 22 kTon/yr Conventional system is SHP

7) Combined Heat & Power (CHP)

7) Fuel Cells

7) Fuel Cells

7) Geothermal, Wind, Nuclear

Requirement 8 Find out what opportunities are available for a career in energy. Choose one position that interest you and describe the education and training required.

Requirement 8

Requirement 2b Use a system that makes at least two energy conversions and explain this to your counselor.

Requirement 1b After you have completed requirements 2-8, revisit the article you found for requirement 1a. Explain to your counselor what you have learned in completing the requirements that helps you better understand the article. Write this in your Energy MB Notebook. When complete – bring it up to me for Blue Card.

Now go out and make or save energy!
