This short briefly, through the use of animation, covers energy sources through human history, covering the benefits and problems of oil, et cetera, before beginning a very mild sermon on the benefits and advantages of solar energy. The producer and directors were a trifle optimistic in thinking that things would take off within five years, but solar power is now one of the power sources which can be seriously considered a good alternative, particularly in areas where there's lots of sunlight most of the year.
Here in Arizona, solar is a viable option and a fair number of businesses and residential properties have gone solar and installed panels, to the point where local utilities have in some instances gotten on the bandwagon.
This short is very well done and is worth searching out. Recommended.
