Energy Sources and Flowcharts

The video introduces Livermore's 2015 energy flowcharts, which have been published since the 1970s. These charts provide insights into the US energy system, including energy resources, electricity generation, and energy usage. The concept of rejected energy, which is energy lost as waste heat, is explained with examples. The video also highlights energy trends in 2015, noting increased use of solar and natural gas, and decreased coal usage. Energy statistics are presented in quadrillion BTUs, with a comparison to kilowatt hours and typical costs.
