Energy Efficiency FUNdamentals WorkshopPat HigbyIntroduction to Energy Efficiency WorkshopBasics of Energy UseEnergy Use Environmental EffectsDefinitions of Energy Efficiency and ConservationActivities (x 4)Watts your Consumption and other smart DevicesEnergy BikeInfrared thermometerRecapActivity: Light Up Your LifeBasics of Energy UseUnited 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.

Transportation Energy Use

Energy and the EnvironmentEnergy sources have different impacts or effects on the environment. Some of these effects may include:emissionswasteland or water use impactsothers.Greenhouse Gas BasicsClimate change indicators slide showhttp://www.epa.gov/climatechange/science/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.

ConnectionWe 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 cycleSince the water cycle is taught in every K-12 school, why not take the opportunity to enrich our students learning to include motivation for changes in energy production and use?

The earth/eaArth water cycleFill 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.

Please volunteer to draw the water cycle!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 considerWhat you cant 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?

How do we solve this problem?

SolutionsChange the way we generate energy to sustainable formsReduce the amount of waste we produceChange our energy usage behavior to conserve more energyImprove our technology to improve energy efficiencyand many moreDefinition of TermsEnergy 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/freeClick on Energy Efficiency from the menuWatch the video on Energy VampiresAre 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)Watts your ConsumptionEnergy Bike

Activity: Light up your LifeBefore you leave today:

You get to take home your own Light up your Life Game
