The major benefit for me is that they are available 24/7, cover a range of topics in all of our classes, and present problems that we haven't seen before."

For the Fall Semester of 2003 the coverage oftopics was changed with students analyzing process dynamics and tuning first, followedby coverage of the mathematical aspects and then more recent developments in controlschemes. The initial homework assignments thus required that the students collect “real”data from a process. This could be accomplished by either dynamic

The first two years of the program are similar to traditional engineering disciplines.Thereafter, one takes a series of courses that introduce Energy Engineering concepts andfundamental energy engineering principles that involve material and energy balances,thermodynamics, fluid mechanics, heat and mass transfer operations, and physical and chemicalprocessing as applied to energy industries. In addition to these engineering principles, studentsenroll in required courses in renewable/sustainable energy principles. Students are trained inbasic chemistry of fuels – coal, petroleum, natural gas and biomass; combustion; petroleum andnatural gas processing; electrochemical energy conversion; and energy conversion processesincluding chemical
