A Steam Powered Generator

The diagram below shows the steps involved in using the energy in steam to generate electricity.

Use the diagram to help you fill in the blanks in the story. Here are the forms of energy that fit into

the blanks: chemical, electrical, heat, light, and mechanical. Some forms of energy may be

used more than once.

(9) _______________________ energy from gas, oil, or coal provides (10) _____________________

energy to water to produce steam. A turbine changes the energy of the steam into the

(11) _______________________ energy of the rotating turbine and generator. The generator

converts this energy into (12)_____________________ energy. The lamp is an energy converter,

changing (13) _______________________ energy to (14) ______________________ energy.
