- wind and hydroelectric power
- wind turbines
- used to grind corns where the term wind turbine came from
- 116 ft blades on top of a 212 ft tower which has a total of 328 ft

- wind and hydroelectric power
- hydroelectric power
- water flows down turns the generator and generates electricity.
- the lower reservoir acts as a pump which pumps water up to the top reservoir where energy is stored
- wave power
- the waves move up and down which drives air past the generators to generate electricity/

- tidal power
- when the tide comes in it drives the turbines and produces a small amount of electricity which is carried away
- the electromagnetic spectrum
- radio waves- 10 to the power of 4
- wavelength and use
- used for communication.
