13. What is the energy efficiency in most electric power planTs

1. energy is the ability to work, for example: people use energy to walk and bicycle, to move cars along roads and boats through water and more.

2. energy can produce heat, power life, move objects, or produce electricity.

3. two types of energy are potential and kinetic energy.

4. kinetic energy

5. four types of potential energy are: elastic, electrical (electromagnetic) , gravitational , and nuclear potential

6. kinetic energy

7. the five types of kinetic energy are: radiant, thermal, sound, electrical and mechanical

8. the law of conservation of energy states that the amount of energy is neither created nor destroyed. for example, when you roll a toy car down a ramp and it hits a wall, the energy is transferred from kinetic energy to potential energy

9. yes energy can change from one form to another

10. there is no exception to this law.

11. energy efficiency is a means of measuring the energy-expenditure required to achieve a certain benefit

12. it changes to heat energy

13. the overall average for the USA is 7% to 8%
