This video is great for hitting number sense skills like scale and unit conversion. Assign your students a specific source of energy and have them identify where the energy comes from (breaking chemical bonds, electron movement, etc.) and how much energy can be generated per specific unit (burning a gall of oil versus the same amount of helium in a fusion reactor). If you do this topic after a food or agriculture unit, you can have students do a problem set where they compare the energy in food using Calories (which are actually kilocalories) versus another  source of energy.

You can also make this lesson all about data visualization. These Sankey diagrams from Lawrence Livermore National Lab are great for discussions of how to communicate a great deal of information graphically. Have students analyze these and then make their own.
