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
