Lesson 6: Energy Transfers and Efficiency in Large-Scale Energy Generation

Overview

Students analyze the way they personally use energy and begin to examine energy use on a much larger scale. Students discover how reliant all sectors (residential, commercial, industrial, transportation) are on electricity and fossil fuels as energy sources. As they investigate the energy transfers involved in the generation of electricity, students consider the efficiency of the transfers involved in the process.
