(Optional) Analyze continuous supply and intermittent supply.

Analysis should address the concept that some sources (e.g., fossil fuel, nuclear, biomass) provide a continuous supply where other sources (e.g., hydro, solar, wind, battery) provide supply intermittently. 

Process/Skill Questions:

• Why are wind and solar considered intermittent supplies of energy?
• What sources are considered continuous? What makes them continuous? What is dispatchability?
• What does off the grid mean? Is it possible to receive continuous energy supply off the grid?
• What can the consumer do to conserve energy? What can producers use to conserve energy?
