Explanation should include the relationship between the source and the final output and the concepts of
- transformation of energy from forms provided by nature to forms that can be used by humans (e.g., windmills, solar panels, hydroelectric plant)
- efficiency ― loss of energy in conversion process (put in 100 percent, never get 100 percent out)
- kinetic energy vs. potential energy.
Process/Skill Questions:
- What are some examples of energy conversion?
- How is efficiency calculated?
- What are some examples of losses in the energy conversion process? Why is energy always lost in the process?
- What factors could improve efficiency?
