This is a slide deck that I used with a classroom of students in a webinar provided by Nepris.com. Nepris is a company that connects classrooms with industry volunteers. Many of these slides are just points for discussion, and they don't all stand alone like a conventional presentation. Basically, the teacher requested an industry expert to discuss the strengths and weakness of alternative energy. I first laid the groundwork by defining energy and contrasting that to the concept of power. Then we discussed all the major forms of energy that we can access on earth. I then highlighted the so-called alternative energy sources. The students were very inquisitive, and I appended their text questions to the slide presentation.
