Chris Sinton University of Redlands Redlands, California

Energy and the Environment 200-level elective course (now required for Environmental Business) Present conventional and renewable energy resources and impacts Focus on quantitative evaluation Lecture mixed with in-class activities and field trips

Energy Project - Goals If it is personal, you remember it Learn how to gather personal energy data Calculate environmental impact Determine impact of efficiency Scale results to campus and state Skills using spreadsheets writing

Equipment Kill-A-Watt Meter Excel Machine(s)

Methodology Choose machine or appliance Plug in meter Take daily reading of kWh and record in Excel Repeat for five days.

Analysis Plot kWh vs. days Determine annual usage and cost Determine environmental impact using emission factors (from US EPA e-grid)US EPA e-grid SOx, NOx, and CO 2

Efficiency Impact Determine impact of efficiency Better machine – Energy Star Change in habit Economic and Environmental Scale results to campus and state
