Basics of Energy Use United States is a developed and Industrialized Nation. Energy is a part of everything we do.
Residential Energy Use Other" includes small electric devices, heating elements, motors, swimming pool heaters, hot tub heaters, outdoor grills, and natural gas outdoor lighting.” http://homeenergysaver.lbl.gov/consumer/learn
Energy and the Environment Energy sources have different impacts or effects on the environment. Some of these effects may include: emissions waste land or water use impacts others.
Greenhouse Gas Basics Climate change indicators slide show http://www.epa.gov/climatechange/scie nce/multimedia.html Did You Know? Most of our carbon dioxide emissions come from using coal and petroleum fuels. Learn more about each major energy source's impact on the environment below.
Graphing Atmospheric CO 2 Keeling Data http://www.uni.edu/free- ceee/sites/default/files/keeling_data.pdf Example of 2 year graph http://www.uni.edu/free- ceee/sites/default/files/sample_co2_grap h.pdf Blank Graphing Sheet with Directions http://www.uni.edu/free- ceee/sites/default/files/graph_keeling_ data_activity.pdf
Connection We use a lot of energy! Most of the energy we use today results in warming the earth. What happens on a warmer Earth? Do the Hot EaArth, Warm Earth activity to find out!
The earth/eaArth water cycle This activity is simple yet very effective for illustrating how a warmer earth changes our water cycle Since the water cycle is taught in every K-12 school, why not take the opportunity to enrich our student’s learning to include motivation for changes in energy production and use?
The earth/eaArth water cycle Fill one styrofoam cup 2/3 full of warm water. This is water you could bathe a baby in, warm, but not too hot! Put the cup in a quart zip-lock bag and seal it. Repeat with a cup of really hot water or coffee fresh from the pot. Do NOT put your finger in this liquid! Observe and note any differences between the two systems.
What happens on a warmer earth? Check your cups! Can you see that more heat allows more evaporation, and thus more condensation? Remove your cups and squeegee the water to a corner of the bag. How does the different amounts of water relate to flooding?
Something else to consider What you can’t see is important, too! The same amount of energy absorbed during evaporation is released during condensation. In the atmosphere this results in strong winds. Is this elaboration?
Connection We use a lot of energy! Most of the energy we use today results in warming the earth. What happens on a warmer Earth? How do we solve this problem?
Solutions Change the way we generate energy to sustainable forms Reduce the amount of waste we produce Change our energy usage behavior to conserve more energy Improve our technology to improve energy efficiency and many more…
Definition of Terms Energy Conservation: is any behavior that results in the use of less energy. Turning the lights off when you leave the room and recycling aluminum cans are both ways of conserving energy. Energy Efficiency: is the use of technology that requires less energy to perform the same function. A compact fluorescent light bulb that uses less energy than an incandescent bulb to produce the same amount of light is an example of energy efficiency. However, the decision to replace an incandescent light bulb with a compact fluorescent is an act of energy conservation.
What About “Energy Vampires”? Go to www.uni.edu/ceee/freewww.uni.edu/ceee/free Click on Energy Efficiency from the menu Watch the video on Energy Vampires Are the devices that prevent Energy Vampires Energy Efficiency or Energy Conservation? Is the decision to use the devices Energy Efficiency or Energy Conservation?
Activities (in partners) Watt’s your Consumption Energy Bike Infrared Thermometer
Recap Energy Bike- One application you could do with Energy Bike in your specialty area Watt’s Your Consumption – Classify objects into Phantom Loads/non-phantom loads Watt’s Your Consumption – What do you conclude about the advantages and disadvantages of the three types of bulbs? Infrared Thermometer-One application you could do from your specialty area
Activity: Light up your Life Before you leave today: You get to take home your own “Light up your Life Game” Please complete the FUNdamentals questionnaire Be sure to attend Solar Energy FUNdamentals Wkshp on February 28! Thanks for Coming
