Lightning is an example of static discharge. During thunderstorms, air swirls violently. Water droplets within the clouds become electrically charged. Electrons collect in the lower parts of the cloud. Electrons move from areas of negative charge to areas of positive charge. As the electrons jump, they produce a spark. The spark is lightning.
A turbine is a circular device made up of many blades. The turbine is like a propeller. The turbine turns the generator that converts mechanical energy to electrical energy.
Electric power can be produced in several ways. Each kind of generating power converts a particular kind of energy into electrical energy.
Energy is stored in the nucleus of the atom. When the nucleus is split, the energy that is released is used to heat water. The water turns into steam, which expands and turns a turbine.
Solar Energy-The sun’s rays can be focused on a tower by large mirrors to boil water. The resulting steam then turns the turbine.
Geothermal Energy- In a few locations on Earth, the underground water near the molten rock is heated until it becomes steam. This steam, which can be obtained through steam vents or drilling, is then used to turn the turbine.
Energy from falling water- Hydroelectric plant near the bases of dams or waterfalls use water to turn the turbines.
Tidal Energy-As the tide moves in and out in a basin behind a dam, the moving water can be used to turn the turbine.
Energy from fossil fuels-Coal, oil, and natural gas can be burned in generating plants to produce steam. The steam pushes against the blades of the turbine, causing it to turn.
Energy from wind- A windmill is essentially a turbine. As the wind blows, it turns the blades of the windmill, which then turn the generator.
The Energy generated goes from the generating power plant…
To the step up transformers (increase voltage)…
