The global appetite for energy is insatiable. The amount of energy generated and consumed annually is mind-boggling. Over the past two years the relevancy of “green” chemistry principles in the undergraduate chemical education curricula has increased on account of the global and national focus and emerging political debate on energy-related issues. In this presentation the author will describe “green” energy activities developed and implemented in both the general chemistry lecture and lab curricula. The learning activities cover the broad spectrum of acknowledged “green” energy resources- solar and fuel cell technologies, wind, and biomass. The activities challenge students to use thermochemical principles and data to determine both the economic and engineering feasibilities for macroscale implementation. For example, students determine the acreage required to supply 15,000 residential homes with electricity generated from photovoltaics and the carbon dioxide emissions savings derived from conversion to solar energy.
