Energy and the Environment200-level elective course (now required
for Environmental Business) Present conventional and renewable
energy resources and impactsFocus on quantitative evaluationLecture mixed with in-class activities and
field trips
Energy Project - GoalsIf it is personal, you remember itLearn how to gather personal energy data Calculate environmental impact Determine impact of efficiency Scale results to campus and stateSkills
using spreadsheets writing
EquipmentKill-A-Watt MeterExcelMachine(s)
MethodologyChoose machine or appliancePlug in meterTake daily reading of kWh and record in
ExcelRepeat for five days.
AnalysisPlot kWh vs. daysDetermine annual usage and costDetermine environmental impact using
emission factors (from US EPA e-grid) SOx, NOx, and CO2
Efficiency ImpactDetermine impact of efficiency
Better machine – Energy StarChange in habit
