Rated 5 out of 5 by from Very objective I was impressed with the lecturer's knowledge and ability to be objective. I was afraid this was going to be a course pushing a certain political viewpoint without the facts. That was not the case, thankfully.

Rated 4 out of 5 by from The Basics of Energy Resources Every Citizen Khow As a retired electric utility tech I enjoyed this course in giving me the basics of other energy sources. It does seem to be more an economics of energy course than science, but valuable information for making wise choices was still there. I especially liked the pros and cons of each energy source. The industry I worked in tended to down play renewables and I never totally bought into that.

Rated 5 out of 5 by from Wonderful and informative course Over 50 of RVing my wife and I have been to 46 of the 50 states and 9 of 13 Canadian Provinces and 11 European Countries. So we have seen world wide examples of oil and gas fields, many different types of power plants, extensive wind farms and solar arrays. We have solar panels on our roof for nearly 40 years. This now gives me a better understanding of the full workings of the wide scope of energy recovery and use around the world.

Rated 5 out of 5 by from You sent me a request for a review before I even got the course delivered to me. By the time I get the course and watch it, I certainly won't have this email link available to me anymore. You really shouldn't ask for a review until at least a month has passed. Please feel welcomed to re-send your request for review sometime later.

Rated 4 out of 5 by from Excellent material and speaker Dr. Wysession is an excellent speaker, and the course is well organized and interesting. My only complaint is that the recording engineer turned down the treble when recording his speach so it'[s quite bass. Difficult to hear of those of us with poor high tones hearing.
