We’ll see how fossil fuels such as coal, oil, and natural gas are used to produce mechanical motion and how that mechanical motion is used to produce electric power. We’ll also examine solar and wind power generation Since the electric current extracts energy from the generator, something must do work on it to keep it turning.
When you turn a bicycle generator rapidly by hand, you can tell whether it’s part
of a completed circuit. If it isn’t part of a circuit, the generator turns relatively easily. If it is, the generator is hard to turn. Why?
we will talk also sbout Heating and Cooling the Steam , Solar Cells and Wind and Water Power
