How do we get electricity?
We get electricity, which is a secondary energy source , from the conversion of other sources of energy, like coal, natural gas, oil, nuclear power and other natural sources, which are called primary sources. Many cities and towns were built alongside waterfalls (a primary source of mechanical energy) that turned water wheels to perform work.
How is electricity produced in the United States?
Most of the electricity in the United States is produced in steam turbines. A turbine converts the kinetic energy of a moving fluid (liquid or gas) to mechanical energy. Steam turbines have a series of blades mounted on a shaft against which steam is forced, thus rotating the shaft connected to the generator.

How many watts is a kilowatt hour?
A kilowatt represents 1,000 watts. A kilowatt-hour (kWh) is equal to the energy of 1,000 watts working for one hour. The amount of electricity a power plant generates or a customer uses over a period of time is measured in kilowatt-hours (kWh).
How does water produce electricity?
The water falls through a pipe called a penstock and applies pressure against the turbine blades to drive the generator to produce electricity. In the second system, called run-of-river, the force of the river current (rather than falling water) applies pressure to the turbine blades to produce electricity.

Keep reading to learn more about how electrical energy powers your life and what examples of electrical energy you can find in the home.
What is the difference between potential and kinetic energy?
Potential vs. Kinetic Electrical Energy. Every type of energy comes in two forms: Potential energy indicates that an object is storing a type of energy, ready to work. An object’s potential energy depends on its material and position. Kinetic energy occurs when an object is actively using energy to do work.

What is the energy that is stored in an atom?
In kinetic energy, the electrons are free to move between valence shells in order to create electrical energy. Thus, the potential energy stored in that atom is converted to kinetic energy...and ultimately, electrical energy.
What is the difference between kinetic energy and kinetic energy?
On the other hand, kinetic energy is essentially energy that moves or moves something else. Kinetic energy transfers its energy onto other objects in order to generate force on that object.
What is the energy that moves when you charge your phone?
When you’re charging your phone, the electricity moving from the wall outlet into your phone battery is kinetic energy. But a battery is designed to hold electricity to use later. That held energy is potential energy, which can become kinetic energy when you’re ready to turn your phone on and use it.
What is work in physics?
In physics, “work” is the energy to an object in order to move an object As we talked about in the last section, electric energy comes from the movement of electrons between atoms, which creates a transfer of energy...also known as work. This work generates electric energy, which is measured in Joules.
How does wind work?
While explaining how wind works deserves a blog post of its own, what you need to know is that when wind hits the turbine’s blades, it turns the rotor hub like a windmill. This kinetic energy turns an internal component, called a nacelle, which contains an electrical generator.
What is electricity in science?
1 a : a fundamental form of energy observable in positive and negative forms that occurs naturally (as in lightning) or is produced (as in a generator) and that is expressed in terms of the movement and interaction of electrons. b : electric current or power.
What is the definition of electricity?
1 a : a fundamental entity of nature consisting of negative and positive kinds, observable in the attractions and repulsions of bodies electrified by friction and in natural phenomena (as lightning or the aurora borealis), and usually utilized in the form of electric currents. b : electric current or power.
What is the meaning of "electric"?
1 : an important form of energy that is found in nature but that can be artificially produced by rubbing together two unlike things (as glass and silk), by the action of chemicals, or by means of a generator. 2 : electric current.
What is electricity in science?
Electricity is the flow of tiny particles called electrons and protons. It can also mean the energy you get when electrons flow from place to place. Electricity can be seen in nature in a bolt of lightning.
How do electrons build up in an object?
Most objects have a balance of positive and negative charges, so they are considered neutral. This means that they do not push or pull on each other electrically. However, sometimes electrons can build up in an object. Two such objects can push or pull on each other because they are no longer neutral. This push or pull from extra electrons is called static electricity. Static electricity can cause interesting effects, such as sparks or lightning bolts, when it is released. Sometimes the extra electrons build up by rubbing one object against another. For example, when one rubs a balloon against one’s hair, electrons move from the balloon to the hair. Because the hairs then all have extra electrons, which all have the same kind of charge, they try to fly away from each other and end up sticking into the air like spikes!
What is the term for the push or pull of electrons?
This push or pull from extra electrons is called static electricity. Static electricity can cause interesting effects, such as sparks or lightning bolts, when it is released. Sometimes the extra electrons build up by rubbing one object against another. For example, when one rubs a balloon against one’s hair, electrons move from the balloon to ...
What is the name of the tiny particles that swirl around each other?
Everything in the universe is made of tiny objects called atoms. Each atom has even tinier particles called protons and electrons. These tiny particles swirl around each other continuously. An electron has what is called a negative charge. A proton has a positive charge.
How does a power plant work?
A city’s power plant produces a powerful electric current and sends it through wires. The electricity used for lighting, heating, and running appliances is made by machines called generators. Generators cause a current to flow by moving a magnet past a coil of wire, which pushes electrons through the wires of the coil.
Who was the first person to study electric forces?
The ancient Greeks were the first to study electric forces. In the American colonies during the 1700s, Benjamin Franklin proved that lightning is a form of electricity. Scientists later learned that electricity is related to magnetism. They then learned how to generate electricity using magnets.
What is the charge of a proton?
A proton has a positive charge. Positive and negative charges try to pull each other together. However, two positive charges, or two negative charges, will push each other away. Electricity results when electrons are pushed and pulled from atom to atom.
